* `E0432: unresolved import prelude` in `src/lib.rs` because `pub use prelude::*;` was attempting to import `prelude` from the current crate's root, not `std::prelude`. - * `E0659: derive is ambiguous` errors across multiple files (e.g., `src/attr.rs`, `src/attr_prop/singletone.rs`, `src/generic_params.rs`). This occurs because `use crate::*;` glob imports conflict with the `derive` attribute macro from the standard prelude. - * `E0412: cannot find type GenericsWithWhere` in `src/generic_params.rs` tests, indicating that `GenericsWithWhere` was not properly exposed for use in tests or by dependent crates. - * A stray doc comment in `src/generic_params.rs` caused a "expected item after doc comment" error. - * **NEW:** `mismatched closing delimiter: `]` in `src/lib.rs` at line 24, indicating a syntax error in a `#[cfg]` attribute. -* These issues prevent `derive_tools` from compiling and testing successfully, as `macro_tools` is a core dependency. Temporary workarounds were applied in `derive_tools`'s context (e.g., `#[allow(ambiguous_glob_reexports)]`), but these are not sustainable or proper fixes for an external crate. +* The `variadic_from_meta` crate depends on `macro_tools` and attempts to use its `struct_like`, `generic_params`, and `typ` modules. During compilation, `macro_tools` itself fails with "cannot find macro `syn_err` in this scope" errors originating from its own source files (`src/item_struct.rs`, `src/typ.rs`). This indicates that a necessary feature for `macro_tools`'s internal compilation, likely related to diagnostics or error handling, is not enabled by default or through the current dependency configuration. This prevents `variadic_from_meta` (and any other crate depending on these `macro_tools` features) from compiling. ### Proposed Solution / Specific Changes -* **API Changes:** - * **`src/lib.rs`:** Change `pub use prelude::*;` to `pub use crate::prelude::*;` to correctly reference the crate's own prelude module. - * **`src/generic_params.rs`:** Ensure `GenericsWithWhere` is publicly exposed (e.g., `pub use own::GenericsWithWhere;` in `src/generic_params/mod.rs` or similar mechanism if `mod_interface!` is used). -* **Behavioral Changes:** - * The `derive` ambiguity issue (E0659) should be addressed by refactoring the `use crate::*;` glob imports in affected files (e.g., `src/attr.rs`, `src/attr_prop/singletone.rs`, etc.) to be more specific, or by explicitly importing `derive` where needed (e.g., `use proc_macro::TokenStream; use syn::DeriveInput;` and then `#[proc_macro_derive(...)]` or `#[derive(...)]`). The current `#[allow(ambiguous_glob_reexports)]` is a temporary workaround and should be removed. -* **Internal Changes:** - * **`src/generic_params.rs`:** Remove the stray doc comment that caused compilation errors. - * **`src/lib.rs`:** Correct the mismatched closing delimiter in the `#[cfg]` attribute at line 24. +* **Enable `diagnostics` feature:** Add the `diagnostics` feature to the `macro_tools` crate's `Cargo.toml`. This feature is commonly used for error reporting and diagnostic utilities in procedural macro helper crates. ### Expected Behavior & Usage Examples (from Requester's Perspective) -* The `macro_tools` crate should compile without errors or warnings. -* `derive_tools` should be able to compile and run its tests successfully without needing `#[allow(ambiguous_glob_reexports)]` or other workarounds related to `macro_tools`. -* `GenericsWithWhere` should be accessible from `derive_tools_meta` for its internal logic and tests. +* The `macro_tools` crate should compile successfully, allowing `variadic_from_meta` to compile and proceed with its refactoring. +* The `syn_err!` and `return_syn_err!` macros should be available for use within `macro_tools`'s internal modules and potentially for re-export. ### Acceptance Criteria (for this proposed change) -* `macro_tools` compiles successfully with `cargo build -p macro_tools --all-targets` and `cargo clippy -p macro_tools -- -D warnings`. -* `derive_tools` compiles and passes all its tests (`cargo test -p derive_tools --all-targets`) without any temporary `#[allow]` attributes related to `macro_tools` issues. +* `cargo build -p macro_tools` (with the `diagnostics` feature enabled) must exit with code 0 and no compilation errors. +* `cargo build -p variadic_from_meta` (which depends on the patched `macro_tools`) must compile successfully. ### Potential Impact & Considerations -* **Breaking Changes:** The proposed changes are primarily fixes and clarifications; they should not introduce breaking changes to `macro_tools`'s public API. -* **Dependencies:** No new dependencies are introduced. -* **Performance:** No significant performance implications are expected. -* **Testing:** Existing tests in `macro_tools` should continue to pass. New tests might be beneficial to cover the `GenericsWithWhere` exposure. +* **Breaking Changes:** No breaking changes are anticipated for `macro_tools`'s public API, as this change primarily affects its internal compilation. +* **Dependencies:** No new external dependencies are expected. +* **Performance:** No significant performance impact is anticipated. +* **Security:** No security implications are anticipated. +* **Testing:** The `macro_tools` crate's existing test suite should continue to pass. New tests specifically for the `diagnostics` feature might be beneficial but are out of scope for this proposal. + +### Alternatives Considered (Optional) +* None, as the error message directly points to a missing macro within `macro_tools`'s own compilation, suggesting a feature-gating issue. ### Notes & Open Questions -* The `derive` ambiguity is a common issue with glob imports and attribute macros. A systematic review of `use crate::*;` in `macro_tools` might be beneficial. \ No newline at end of file +* Confirm if `diagnostics` is indeed the correct feature name for enabling `syn_err!` and `return_syn_err!`. If not, further investigation into `macro_tools`'s internal structure would be required by its maintainers. \ No newline at end of file diff --git a/module/core/mod_interface/Cargo.toml b/module/core/mod_interface/Cargo.toml index 87cda47286..5d8ab5f4d3 100644 --- a/module/core/mod_interface/Cargo.toml +++ b/module/core/mod_interface/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "mod_interface" -version = "0.34.0" +version = "0.35.0" edition = "2021" authors = [ "Kostiantyn Wandalen ", diff --git a/module/core/mod_interface_meta/Cargo.toml b/module/core/mod_interface_meta/Cargo.toml index 3ec8ff343e..f48f47ba9a 100644 --- a/module/core/mod_interface_meta/Cargo.toml +++ b/module/core/mod_interface_meta/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "mod_interface_meta" -version = "0.32.0" +version = "0.33.0" edition = "2021" authors = [ "Kostiantyn Wandalen ", diff --git a/module/core/strs_tools/changelog.md b/module/core/strs_tools/changelog.md new file mode 100644 index 0000000000..9cd33c787a --- /dev/null +++ b/module/core/strs_tools/changelog.md @@ -0,0 +1,2 @@ +* [Increment 1 | 2025-07-08 09:58 UTC] Added a failing test case to `strs_tools` to reproduce the iterator compilation error. +* [Increment 2 | 2025-07-08 10:01 UTC] Corrected the `IntoIterator` implementation for `SplitOptions` and fixed the test case. \ No newline at end of file diff --git a/module/core/strs_tools/plan.md b/module/core/strs_tools/plan.md deleted file mode 100644 index c252df9117..0000000000 --- a/module/core/strs_tools/plan.md +++ /dev/null @@ -1,177 +0,0 @@ -# Project Plan: Enhance SplitIterator for Quoted Sections in `strs_tools` - -### Goal -* Modify `strs_tools::string::split::SplitIterator` to correctly tokenize strings containing quoted sections, ensuring that internal delimiters (e.g., spaces, `::`) within a quoted section are *not* treated as delimiters.

Focus on formatting, spacing, newlines, attribute placement, and `use` statement organization. - * Crucial Design Rules: [Code Style: Do Not Reformat Arbitrarily], [New Lines for Blocks], [Indentation], [Spaces Around Symbols], [Attributes: Spaces], [Attributes: Separate Attributes from Items], [Where Clause Formatting], [Trait Implementation Formatting], [Function Signature Formatting], [Comments: Spaces], [Nesting], [Code Length], [Lifetime Annotations]. - * Relevant Behavior Rules: N/A. - * Verification Strategy: - * Execute `cargo fmt --check -p strs_tools` via `execute_command`. Analyze output (expecting no unformatted files). - * Execute `cargo clippy -p strs_tools -- -D warnings` via `execute_command`. Analyze output (expecting no warnings). - * Execute `cargo test -p strs_tools --all-targets` via `execute_command`. Analyze output (all tests must pass). - * Commit Message: `style(strs_tools): Apply strict codestyle rules` - -### Task Requirements -* All changes must be within `module/core/strs_tools`. -* The solution should follow "Option 1 (Preferred): Modify `SplitIterator` to dynamically adjust `SplitFastIterator`'s delimiters." from the task description. (This seems completed by prior increments). -* The `debug_hang_split_issue` test in `strs_tools` must pass. -* All tests in `module/move/unilang_instruction_parser` (especially those related to quoted arguments) must pass after this change is implemented in `strs_tools`. (Note: This requirement is now addressed by proposing a fix to `unilang_instruction_parser`). -* The `strs_tools` crate must have no clippy warnings after all increments are complete. -* **The `strs_tools` crate must strictly adhere to all codestyle rules defined in `code/rules/codestyle.md`.** - -### Project Requirements -* Must use Rust 2021 edition. -* All new APIs must be async (not applicable for this task). -* All dependencies must be centralized in workspace `Cargo.toml`. -* Lints must be defined in workspace `Cargo.toml` and inherited by crates. -* **New Global Constraint:** Never use `#[allow(clippy::missing_errors_doc)]`. - -### Notes & Insights -* The `last_yielded_token_was_delimiter` state in `SplitIterator` was key to correctly inserting empty segments before a quote that followed a delimiter when `preserving_empty` is true. -* The `unilang_instruction_parser` test `named_arg_with_quoted_escaped_value_location` expects the `value_location` to be the span of the *unescaped content* in the *original string*, which means excluding the outer quotes. The current `strs_tools` implementation was returning the span including the quotes. -* **Clarification from `strs_tools/-task.md`:** `strs_tools` is responsible for providing the *raw content* of the quoted string (excluding outer quotes) and its corresponding span. Unescaping is the responsibility of `unilang_instruction_parser`. The `strs_tools` plan's Rule 1 has been updated to reflect this. -* The `pub mod private` change in `split.rs` was a temporary diagnostic step. Increment 5 has addressed this by making `mod private` non-pub and ensuring necessary items within it are accessible for re-export or tests. -* The `clippy::struct_excessive_bools` lint for `SplitOptions` was addressed by refactoring to use `bitflags`. -* A `bitflags` dependency was added to `module/core/strs_tools/Cargo.toml`. This should ideally be moved to the workspace `Cargo.toml` and inherited. This can be a follow-up task or addressed if other workspace changes are made. \ No newline at end of file diff --git a/module/core/strs_tools/spec.md b/module/core/strs_tools/spec.md new file mode 100644 index 0000000000..f2e4fcc78d --- /dev/null +++ b/module/core/strs_tools/spec.md @@ -0,0 +1,289 @@ +# Technical Specification: `strs_tools` (Definitive, Reviewed Version) + +## Section 1: Global Architecture & Principles + +This section defines the high-level architecture, rules, and design philosophies that apply to the entire `strs_tools` library. + +### 1.1. Goals & Philosophy + +The primary goal of `strs_tools` is to provide a powerful and flexible set of string manipulation utilities that empower developers to parse complex data with confidence and clarity. + +* **Configurability over Hardcoding:** Employ a fluent builder pattern (Formers). +* **Correctness and Robustness:** Prioritize correct handling of edge cases. +* **Modularity and Pay-as-you-go:** Utilize a feature-gating system. +* **Clarity and Ergonomics:** Provide a clear and discoverable API. + +### 1.2. Architectural Principles + +These are the non-negotiable, crate-wide design laws. + +1. **Consumer Owns Unescaping:** The library **must not** perform any interpretation of escape sequences (e.g., `\"` -> `"`). It yields raw string slices. This is a critical security and correctness principle. +2. **Panic on Invalid Configuration:** `Former` structures **must** panic if consumed with an invalid configuration. This treats configuration errors as developer errors. +3. **Composition of Layers:** Higher-level modules **must** be implemented by composing the public APIs of lower-level modules. +4. **Graceful Handling of Malformed Input:** The library **must not** panic on malformed user input (e.g., unclosed quotes) during iteration. + +### 1.3. API Design & Namespace Philosophy + +The library's public API is exposed through a deliberate, four-tiered namespace structure to provide flexibility for different import styles. + +* **`private` (Internal):** Contains all implementation details. It is not part of the public API. +* **`own`:** Contains the primary, owned types of a module (e.g., `SplitIterator`). This is for developers who want to be explicit and avoid name clashes. + * *Usage Example:* `use strs_tools::string::split::own::SplitIterator;` +* **`exposed`:** Re-exports the `own` namespace under the module's name (e.g., `pub use super::own as split`). This is the intended entry point for qualified path usage. + * *Usage Example:* `strs_tools::string::split::split()` +* **`prelude`:** Contains the most essential types and builder functions intended for convenient glob import. + * *Usage Example:* `use strs_tools::prelude::*; let iter = split()...;` +* **`orphan`:** An internal implementation detail used to structure the re-exports between `exposed` and `own`. It should not be used directly. + +### 1.4. Component Interaction Model + +The `strs_tools` library is designed as a system of composable layers. Higher-level modules delegate their core parsing logic to the `split` tokenizer, ensuring consistent behavior. + +#### Static Structure + +This diagram shows the static relationships between the main components. + +```mermaid +graph TD + subgraph User Facing API + A[parse_request::request_parse] --> B{Request String}; + C[split::split] --> D{Source String}; + E[isolate::isolate_left] --> D; + end + + subgraph Core Logic + A -- delegates to --> C; + A -- also delegates to --> E; + C -- yields --> F[Split Iterator]; + end + + style A fill:#cde4ff,stroke:#333,stroke-width:2px + style C fill:#cde4ff,stroke:#333,stroke-width:2px + style E fill:#cde4ff,stroke:#333,stroke-width:2px +``` + +#### Dynamic Flow (Sequence Diagram) + +This diagram illustrates the sequence of calls for a typical `parse_request` operation, demonstrating the "Composition of Layers" principle in action. + +```mermaid +sequenceDiagram + actor User + participant PR as parse_request + participant S as split + participant I as isolate + + User->>PR: Calls .parse() on "cmd k:v" + activate PR + PR->>S: Calls .perform() on "cmd k:v" with "" delimiter + activate S + S-->>PR: Returns iterator yielding ["cmd k:v"] + deactivate S + PR->>I: Calls .isolate() on "cmd k:v" with ":" delimiter + activate I + I-->>PR: Returns ("cmd", Some(":"), "k:v") + deactivate I + PR->>S: Calls .perform() on "k:v" with ":" delimiter + activate S + S-->>PR: Returns iterator yielding ["k", "v"] + deactivate S + PR-->>User: Returns Request struct { subject: "cmd", map: {"k": "v"} } + deactivate PR +``` + +### 1.5. API Usage & Lifetime Considerations + +This section addresses critical design aspects of the API that affect how it must be used, particularly concerning data ownership and lifetimes. Failure to adhere to these patterns will likely result in compiler errors. + +#### 1.5.1. Handling Dynamic Delimiters (The `E0716` Pitfall) + +A primary design choice of the `split` module is that it **borrows** its delimiters. The `SplitOptionsFormer` holds a lifetime `'a` and expects string slices (`&'a str`) that live at least as long as the `Former` itself. This has a critical implication when working with owned `String` data. + +**Problematic Pattern (will not compile):** +```rust,ignore +// This code will fail with E0716: temporary value dropped while borrowed +let my_delims: Vec = vec!["a".to_string(), "b".to_string()]; +let iter = split() + // This creates a temporary Vec<&str> that is dropped at the end of the line, + // leaving the Former with dangling references. + .delimeter(my_delims.iter().map(|s| s.as_str()).collect::>()) + .src("c a d b e") + .perform(); +``` + +**Correct Pattern:** +The `Vec<&str>` containing the borrowed slices must be bound to a variable with a lifetime that encloses the use of the `Former`. + +```rust +let my_delims: Vec = vec!["a".to_string(), "b".to_string()]; +// 1. Create the vector of slices and bind it to a variable. +let delims_as_slices: Vec<&str> = my_delims.iter().map(|s| s.as_str()).collect(); + +// 2. Pass the bound variable to the Former. `delims_as_slices` now lives +// long enough for the `perform()` call. +let iter = split() + .delimeter(delims_as_slices) + .src("c a d b e") + .perform(); +``` + +#### 1.5.2. The `&mut Self` Builder Pattern + +The `Former` structs in this library use a builder pattern where configuration methods (e.g., `.src()`, `.quoting()`) return a mutable reference (`&mut Self`) rather than an owned value (`Self`). + +* **Implication:** This means a configured `Former` cannot be directly returned from a function, as this would involve moving out of a mutable reference. +* **Rationale:** This design allows a `Former` to be created and then conditionally modified in multiple steps within the same scope before being consumed. + +### 1.6. Non-Functional Requirements (NFRs) + +| ID | Requirement | Description | Verification | +| :--- | :--- | :--- | :--- | +| **NFR-1** | **Performance** | Iteration over a string **must not** involve unnecessary allocations. The `SplitIterator` should be lazy and only perform work when `.next()` is called. | Benchmarks must show that splitting a large string without collecting has a low, constant memory overhead. | +| **NFR-2** | **Memory** | The library must be usable in `no_std` environments (with `alloc`). | The crate must successfully compile and pass all relevant tests with the `no_std` and `use_alloc` features enabled. | +| **NFR-3** | **Modularity** | Feature gates **must** successfully exclude unused modules from compilation. | Compiling with `--no-default-features --features string_split` must not compile the `parse_request` or `indentation` modules. | + +### 1.7. Out of Scope + +To clarify the library's boundaries, the following functionalities are explicitly out of scope: + +* **Character Set Conversion:** The library operates on Rust `&str` slices and assumes the input is valid UTF-8. It does not perform any encoding or decoding. +* **Content Unescaping:** As per the architectural principles, the library does not interpret escape sequences (e.g., `\n`, `\t`, `\"`). This is the responsibility of the consumer. +* **Network or I/O Operations:** This is a pure string manipulation library and will not include any features for reading from files, sockets, or other I/O sources. + +--- + +## Section 2: Component Specifications + +This section provides a detailed specification for each public module. + +### 2.1. Module: `string::split` + +#### Purpose + +The core tokenization engine. It splits a string based on a complex set of rules, including multiple delimiters and quoted sections. + +#### Internal Architecture + +The module uses a two-iterator wrapper pattern. The user-facing `SplitIterator` provides the rich feature set (quoting, stripping) by managing and interpreting the raw output of a more primitive, internal `SplitFastIterator`. + +```mermaid +graph TD + subgraph Public API + A[SplitOptionsFormer] -- .perform() --> B(SplitIterator); + end + subgraph Internal Logic + B -- Wraps & Manages --> C(SplitFastIterator); + C -- Performs basic tokenization --> D{Raw Split Segments}; + B -- Applies quoting/filtering rules to --> D; + B -- Yields --> E[Final Split Struct]; + end + style B fill:#cde4ff,stroke:#333,stroke-width:2px +``` + +#### Core Data Structures & API + +* **`struct Split<'a>`**: Represents a segment with `string`, `typ`, `start`, and `end` fields. +* **`enum SplitType`**: `Delimited` or `Delimiter`. +* **`bitflags! struct SplitFlags`**: `PRESERVING_EMPTY`, `PRESERVING_DELIMITERS`, `PRESERVING_QUOTING`, `STRIPPING`, `QUOTING`. +* **`SplitOptionsFormer<'a>`**: The builder returned by `split()`. Provides methods like `.src()`, `.delimeter()`, `.quoting(bool)`, etc., and is consumed by `.perform()`. + +### 2.2. Module: `string::parse_request` + +#### Purpose + +A higher-level parser for structured commands that have a subject and a map of key-value properties. + +#### Core Data Structures & API + +* **`struct Request<'a>`**: Represents a parsed request with `original`, `subject`, `subjects`, `map`, and `maps` fields. +* **`enum OpType`**: A wrapper for a property value: `Primitive(T)` or `Vector(Vec)`. +* **`ParseOptions<'a>`**: The builder returned by `request_parse()`. Provides methods like `.src()`, `.key_val_delimeter()`, and is consumed by `.parse()`. + +### 2.3. Module: `string::isolate` + +#### Purpose + +A specialized function to split a string into exactly three parts: left content, the first delimiter, and right content. + +#### Core Data Structures & API + +* **`IsolateOptions<'a>`**: A builder returned by `isolate_left()` or `isolate_right()`. +* `.isolate() -> (&'a str, Option<&'a str>, &'a str)`: Consumes the builder and returns the result tuple. + +### 2.4. Module: `string::indentation` + +#### Purpose + +A stateless function to add a prefix and/or postfix to each line of a string. + +#### Core Data Structures & API + +* `indentation(prefix, src, postfix) -> String`: A direct function call. + +### 2.5. Module: `string::number` + +#### Purpose + +A thin wrapper around the `lexical` crate for parsing numbers, managed by the `string_parse_number` feature gate. + +#### Core Data Structures & API + +* Re-exports functions like `parse()` and `parse_partial()` from the `lexical` crate. + +--- + +### Section 3: Verification + +#### 3.1.

The entire content of a quoted section (excluding outer quotes, but including escaped inner quotes and delimiters) should be returned as a single `Delimeted` item. +* To fix a bug in `strs_tools::string::split` where quoted strings containing escaped quotes (`\"`) or escaped backslashes (`\\`) are not correctly unescaped when `quoting(true)` is enabled. The goal is for the `Split` struct's `string` field to contain the fully unescaped value. ### Problem Statement / Justification -* The `unilang_instruction_parser` relies on `strs_tools::string::split::SplitIterator` for tokenization. When `SplitIterator` encounters a quoted section (e.g., `"value with spaces and :: delimiters"`), it currently treats the internal spaces and `::` as delimiters, breaking the quoted string into multiple `Split` items. This is incorrect behavior for a quoted string, which should be treated as a single literal value. -* The current `handle_quoted_section` in `SplitIterator` attempts to consume the quoted content, but `SplitFastIterator` (its internal iterator) continues to find internal delimiters, leading to incorrect tokenization. -* This prevents `unilang_instruction_parser` from correctly parsing commands with quoted arguments containing spaces or other delimiters, leading to parsing errors and hangs. +* The `unilang_instruction_parser` relies on `strs_tools` for tokenization, including handling of quoted strings. Currently, `strs_tools::string::split` with `quoting(true)` correctly identifies quoted segments but fails to unescape characters like `\"` and `\\` within those segments. This leads to incorrect parsing of instruction arguments that contain such escaped characters, causing functional errors in `unilang_instruction_parser`. The bug was identified and confirmed by a Minimal Reproducible Example (MRE) test case. ### Proposed Solution / Specific Changes -* **Option 1 (Preferred): Modify `SplitIterator` to dynamically adjust `SplitFastIterator`'s delimiters.** - * Introduce a mechanism in `SplitIterator` to temporarily disable or change the set of active delimiters for its internal `SplitFastIterator` when inside a quoted section. - * When an opening quote is encountered, `SplitIterator` should switch `SplitFastIterator` to a mode where only the matching closing quote (and potentially escaped characters) are considered delimiters. - * Once the closing quote is found, switch back to the original set of delimiters. -* **Option 2 (Alternative): Enhance `handle_quoted_section` to consume all internal tokens.** - * Modify `handle_quoted_section` to not just find the closing quote, but to also consume all intermediate `Split` items from `self.iterator` (the `SplitFastIterator`) until the closing quote is reached. These intermediate items should be discarded or concatenated into the main quoted string. This might be more complex to manage state. +* **File:** `src/string/split.rs` +* **Function:** `SplitFastIterator::next` +* **Change:** Modify the loop that searches for the end of a quoted segment to correctly handle escaped characters. The current `is_escaped` boolean toggle is insufficient. A more robust iteration is needed to skip characters immediately following a backslash. +* **Example of current buggy behavior (from MRE):** + Input: `".command "hello \" world""` + `strs_tools::split` output for quoted part: `"hello \\\" world"` (incorrectly retains backslashes) + Expected `strs_tools::split` output for quoted part: `hello " world` (correctly unescaped) + +* **Proposed Code Change (conceptual, based on previous attempt):** + Replace the `is_escaped` logic in `SplitFastIterator::next` with a loop that explicitly skips characters after a backslash. + + ```rust + // Inside SplitFastIterator::next, within the `if let Some( current_quote_char ) = self.active_quote_char` block: + let mut end_of_quote_idx : Option< usize > = None; + let mut char_indices = self.iterable.char_indices(); + 'outer: while let Some( ( i, c ) ) = char_indices.next() + { + if c == '\\' + { + // Skip the escaped character + char_indices.next(); + } + else if c == current_quote_char + { + end_of_quote_idx = Some( i + c.len_utf8() ); + break 'outer; + } + } + ``` + This change ensures that the `SplitFastIterator` correctly identifies the end of the quoted segment, allowing the `unescape_str` function (which already exists and handles unescaping) to receive the correct input. ### Expected Behavior & Usage Examples (from Requester's Perspective) -* Given input: `cmd arg::"value with spaces and :: delimiters"` -* `SplitIterator` should produce: - * `Split { string: "cmd", typ: Delimeted, ... }` - * `Split { string: " ", typ: Delimiter, ... }` - * `Split { string: "arg", typ: Delimeted, ... }` - * `Split { string: "::", typ: Delimiter, ... }` - * `Split { string: "value with spaces and :: delimiters", typ: Delimeted, ... }` (This should be a single item, with outer quotes stripped, and internal escapes handled by `unilang_instruction_parser` later). +* When `strs_tools::split` is called with `quoting(true)` on an input string like `".command "hello \\" world""`, the resulting `Split` item for the quoted part should have its `string` field contain `Cow::Owned("hello \" world")` (i.e., the backslash before the quote is removed, and the quote is unescaped). +* Similarly, for `".command "path\\\\to\\\\file""`, the `Split` item should contain `Cow::Owned("path\\to\\file")`. ### Acceptance Criteria (for this proposed change) -* `strs_tools::string::split::SplitIterator` correctly tokenizes quoted strings as single delimited items, ignoring internal delimiters. -* The `debug_hang_split_issue` test in `strs_tools` passes and produces the expected single `Split` item for the quoted string. -* All tests in `module/move/unilang_instruction_parser` (especially those related to quoted arguments) pass after this change is implemented in `strs_tools`. +* The `strs_tools::string::split` function, when used with `quoting(true)`, must correctly unescape `\"` and `\\` sequences within quoted segments. +* A new test case (similar to the MRE created previously) should be added to `strs_tools` to verify this specific unescaping behavior. +* All existing `strs_tools` tests must continue to pass. ### Potential Impact & Considerations -* **Breaking Changes:** This might introduce breaking changes if `SplitIterator`'s behavior for quoting is fundamentally altered. Careful consideration of existing uses of `SplitIterator` is needed. -* **Performance:** The new logic should be efficient and not introduce performance regressions. -* **Complexity:** The solution should aim for clarity and maintainability. +* **Breaking Changes:** No breaking changes are anticipated to the public API of `strs_tools`. This is a bug fix. +* **Dependencies:** No new dependencies are required. +* **Performance:** The change involves a slightly more complex loop for parsing quoted strings, but the performance impact is expected to be negligible for typical string lengths. +* **Testing:** New unit/integration tests should be added to `strs_tools` to cover the unescaping of `\"` and `\\` within quoted strings. ### Notes & Open Questions -* The current `handle_quoted_section` logic for finding the unescaped postfix seems to be correct after the last fix. The problem is the interaction with `SplitFastIterator`'s continued tokenization. -* The `SplitIterator` needs to effectively "take control" of the parsing when a quoted section begins, preventing `SplitFastIterator` from yielding internal delimiters. +* The `unescape_str` function already exists in `strs_tools::string::split` and appears to handle the actual unescaping correctly. The issue is that `SplitFastIterator` is not providing the correct string slice to `unescape_str` due to its flawed quote-end detection logic. \ No newline at end of file diff --git a/module/core/strs_tools/task/task.md b/module/core/strs_tools/task/task.md new file mode 100644 index 0000000000..4b1641fdb4 --- /dev/null +++ b/module/core/strs_tools/task/task.md @@ -0,0 +1,110 @@ +# Change Proposal for strs_tools + +### Task ID +* TASK-20250708-202400-StrsToolsUnescape + +### Requesting Context +* **Requesting Crate/Project:** `unilang_instruction_parser` +* **Driving Feature/Task:** Refactoring `unilang_instruction_parser` to be robust and spec-compliant, which requires correct tokenization and unescaping of quoted strings. +* **Link to Requester's Plan:** `module/move/unilang_instruction_parser/task/task_plan.md` +* **Date Proposed:** 2025-07-08 + +### Overall Goal of Proposed Change +* To enhance `strs_tools::string::split` functionality to correctly parse and unescape quoted strings, treating them as single tokens and removing escape sequences, when `quoting(true)` is enabled. + +### Problem Statement / Justification +The `unilang_instruction_parser` crate relies on `strs_tools` for tokenization, specifically for handling quoted strings. Current behavior of `strs_tools::split` with `quoting(true)` does not correctly: +1. Treat an entire quoted string (e.g., `"value with spaces"`) as a single `Delimeted` token when internal delimiters (like spaces) are present. Instead, it splits the quoted string by internal delimiters. +2. Perform unescaping of escape sequences (e.g., `\"`, `\\`) within quoted strings. The `string` field of the `Split` struct retains the raw, escaped content. + +This prevents `unilang_instruction_parser` from correctly parsing instructions with quoted arguments, leading to parsing errors and requiring complex, redundant unescaping logic in the consumer crate. + +**Minimal Reproducible Example (`strs_tools_mre.rs`):** +```rust +//! Minimal reproducible example for strs_tools unescaping bug. + +use strs_tools::string::split::Split; + +fn main() +{ + let input = r#"cmd key::"value with \"quotes\" and \\slash\\""#; + let splits_iter = strs_tools::split() + .src( input ) + .delimeter( vec![ " ", "::" ] ) + .preserving_delimeters( true ) + .quoting( true ) + .form() + .split(); // Use the full iterator + + let splits: Vec< Split<'_> > = splits_iter.collect(); + println!( "{:#?}", splits ); +} +``` +**Current Output of MRE:** +``` +[ + Split { + string: "cmd", + typ: Delimeted, + start: 0, + end: 3, + }, + Split { + string: " ", + typ: Delimiter, + start: 3, + end: 4, + }, + Split { + string: "key", + typ: Delimeted, + start: 4, + end: 7, + }, + Split { + string: "::", + typ: Delimiter, + start: 7, + end: 9, + }, + Split { + string: "\"value with \\\"quotes\\\" and \\\\slash\\\"", + typ: Delimeted, + start: 9, + end: 45, + }, +] +``` +Expected output for the last `Split` item (after fix): +`Split { string: "value with \"quotes\" and \slash\", typ: Delimeted, start: 9, end: 45 }` (unescaped content) + +### Proposed Solution / Specific Changes +Modify the `strs_tools::string::split::SplitIterator` to: +1. Ensure that when `quoting(true)` is enabled, the iterator consumes the entire quoted segment (from opening to closing quote, respecting escape sequences) as a single `Split` item, regardless of internal delimiters. +2. Perform unescaping of standard escape sequences (e.g., `\"`, `\\`, `\n`, `\t`, `\r`) within the quoted string content. +3. **API Change Consideration:** Ideally, the `Split` struct's `string` field should be `Cow<'a, str>` to allow returning an owned `String` for unescaped content. If this is not feasible without a major version bump, a compromise might be to provide an `unescaped_string()` method on `Split` or a separate unescaping utility. However, the primary goal is for `Split.string` to contain the unescaped value directly when `quoting(true)` is used. + +### Expected Behavior & Usage Examples (from Requester's Perspective) +Given the input: `cmd key::"value with \"quotes\" and \\slash\\"` +When `strs_tools::split().src(input).quoting(true).form().split()` is called: +The resulting `Split` for the quoted segment should be: +`Split { string: "value with \"quotes\" and \slash\", typ: Delimeted, start: 9, end: 45 }` +(Note: The `string` field here should contain the *unescaped* value, i.e., `value with "quotes" and \slash\`. The current MRE output shows it's still escaped.) + +### Acceptance Criteria (for this proposed change) +1. The `strs_tools_mre.rs` (provided in the `Problem Statement` section of this `task.md`) when run, produces a `Split` output for the quoted string where: + * The entire quoted string is a single `Split` item. + * The `string` field of this `Split` item contains the *unescaped* content (e.g., `value with "quotes" and \slash\`). +2. No regressions are introduced to existing `strs_tools` functionality. + +### Potential Impact & Considerations +* **Breaking Changes:** Changing `Split.string` from `&'a str` to `Cow<'a, str>` would be a breaking change. If this is not desired, an alternative unescaping mechanism would be needed, but it would be less ergonomic. +* **Performance:** Unescaping involves allocation for owned strings. This should be considered for performance-critical paths. +* **Testing:** New unit and integration tests should be added to `strs_tools` to cover various quoting and unescaping scenarios. + +### Alternatives Considered +* Implementing unescaping logic directly in `unilang_instruction_parser`: Rejected, as it duplicates functionality that should ideally reside in the tokenization layer (`strs_tools`) and contradicts the architectural mandate to use `strs_tools` as the core tokenizer. + +### Notes & Open Questions +* Clarification on the intended behavior of `quoting(true)` regarding unescaping. +* Guidance on whether a breaking change to `Split` (e.g., `Cow<'a, str>`) is acceptable for this functionality. \ No newline at end of file diff --git a/module/core/strs_tools/task/task_plan.md b/module/core/strs_tools/task/task_plan.md new file mode 100644 index 0000000000..06ff533d06 --- /dev/null +++ b/module/core/strs_tools/task/task_plan.md @@ -0,0 +1,164 @@ +# Task Plan: Remove `bitflags` dependency from `strs_tools` + +### Goal +* To eliminate the `bitflags` crate dependency from `module/core/strs_tools` by replacing its functionality with a custom implementation, ensuring all existing features and tests continue to pass without regression. + +### Ubiquitous Language (Vocabulary) +* **Bitflags:** The `bitflags` crate, used for creating a type-safe way to work with bitmasks. +* **Custom Flag Type:** A new enum or struct that will replace the functionality provided by `bitflags`. +* **StrsTools:** The `module/core/strs_tools` crate, the primary target for this task. + +### Progress +* **Roadmap Milestone:** N/A +* **Primary Editable Crate:** `module/core/strs_tools` +* **Overall Progress:** 0/5 increments complete +* **Increment Status:** + * ⏳ Increment 1: Analyze `bitflags` usage and prepare for replacement. + * ⚫ Increment 2: Implement custom flag type. + * ⚫ Increment 3: Replace `bitflags` usage in `src/string/split.rs`. + * ⚫ Increment 4: Remove `bitflags` dependency from `Cargo.toml`. + * ⚫ Increment 5: Finalization. + +### Permissions & Boundaries +* **Mode:** code +* **Run workspace-wise commands:** false +* **Add transient comments:** true +* **Additional Editable Crates:** + * N/A + +### Relevant Context +* Control Files to Reference (if they exist): + * `./roadmap.md` + * `./spec.md` + * `./spec_addendum.md` +* Files to Include (for AI's reference, if `read_file` is planned): + * `module/core/strs_tools/Cargo.toml` + * `module/core/strs_tools/src/string/split.rs` + * `module/core/strs_tools/tests/inc/split_test/quoting_and_unescaping_tests.rs` +* Crates for Documentation (for AI's reference, if `read_file` on docs is planned): + * `strs_tools` +* External Crates Requiring `task.md` Proposals (if any identified during planning): + * N/A + +### Expected Behavior Rules / Specifications +* The `strs_tools` crate must compile successfully after the changes. +* All existing tests for `strs_tools` must pass after the changes. +* The functionality of string splitting, quoting, and unescaping must remain identical to its current behavior. +* The `bitflags` dependency must be completely removed from `strs_tools/Cargo.toml`. + +### Tests +| Test ID | Status | Notes | +|---|---|---| + +### Crate Conformance Check Procedure +* 1.

Refactor the `variadic_from` and `variadic_from_meta` crates to be fully compliant with `spec.md`. This involves correcting the derive macro's code generation, overhauling the test suite for comprehensive coverage, updating documentation to be accurate and testable, and ensuring all code adheres to the project's codestyle. - -### Ubiquitous Language (Vocabulary) -* **Variadic Constructor:** A constructor that can accept a variable number of arguments, implemented via the `from!` macro. -* **`FromN` Traits:** A set of traits (`From1`, `From2`, `From3`) defining a contract for constructing a type from `N` arguments. -* **`VariadicFrom` Trait:** A marker trait (`#[derive(VariadicFrom)]`) that triggers the automatic implementation of `FromN` and standard `From` traits. -* **Convenience Implementation:** An `impl FromM for StructWithNFields` where `M < N`, generated only when field types are identical, for ergonomic single-argument construction. - -### Progress -* **Roadmap Milestone:** N/A -* **Primary Editable Crate:** `module/core/variadic_from` -* **Overall Progress:** 1/4 increments complete -* **Increment Status:** - * ✅ Increment 1: Refactor `variadic_from_meta` for Spec Compliance - * ⏳ Increment 2: Overhaul and Restructure Test Suite - * ⚫ Increment 3: Refactor `variadic_from` Library and Update `Readme.md` - * ⚫ Increment 4: Finalization - -### Permissions & Boundaries -* **Mode:** code -* **Run workspace-wise commands:** true -* **Add transient comments:** true -* **Additional Editable Crates:** - * `module/core/variadic_from_meta` - -* [Increment 2 | 2025-07-06 09:34 UTC] Fixed `quote!` macro repetition issues in `variadic_from_meta/src/lib.rs` by using direct indexing for arguments and types. -### Relevant Context -* **Specification:** `module/core/variadic_from/spec.md` -* **Codestyle:** `code/rules/codestyle.md` -* **Files to Modify:** - * `module/core/variadic_from/src/lib.rs` - * `module/core/variadic_from/src/variadic.rs` - * `module/core/variadic_from/Readme.md` - * `module/core/variadic_from/tests/inc/mod.rs` - * `module/core/variadic_from_meta/src/lib.rs` - * `module/core/variadic_from_meta/Cargo.toml` - -### Crate Conformance Check Procedure -* **Step 1: Run All Tests.** Execute `timeout 90 cargo test --workspace` and verify no failures. -* **Step 2: Run Linter.** Execute `timeout 90 cargo clippy --workspace -- -D warnings` and verify no errors or warnings. -* **Step 3: Run Doc Tests.** Execute `timeout 90 cargo test --workspace --doc` and verify no failures. -* **Step 4: Check Git Status.** Execute `git status` to ensure no unexpected uncommitted files. - -### Increments - -##### Increment 1: Refactor `variadic_from_meta` for Spec Compliance -* **Goal:** Correct the `VariadicFrom` derive macro to generate code that strictly adheres to `spec.md`. -* **Specification Reference:** `spec.md` Section 3.1, 6.4 -* **Steps:** - 1. Read `module/core/variadic_from_meta/src/lib.rs` and `module/core/variadic_from_meta/Cargo.toml`. - 2. In `lib.rs`, remove `attributes(from)` from the `#[proc_macro_derive]` definition. - 3. Refactor the code generation logic to be modular. Create helper functions to generate `FromN` impls and `From` impls. - 4. Modify the `From` and `From<(T1, ...)>` generation to **delegate** to the corresponding `FromN` trait method (e.g., `fn from(src: T) -> Self { Self::from1(src) }`). - 5. Implement conditional logic for generating convenience `FromN` implementations. This requires comparing `syn::Type` equality. - * For 2-field structs, generate `impl From1` only if `field_type_1 == field_type_2`. - * For 3-field structs, generate `impl From1` only if all three field types are identical. - * For 3-field structs, generate `impl From2` only if the second and third field types are identical. - 6.

In `tests/inc/mod.rs`, remove all old module declarations. - 3. Create a new test file `tests/inc/derive_test.rs`. - 4. In `derive_test.rs`, add comprehensive tests covering: - * **1-field structs:** Named and unnamed, `From` and `from!` usage. - * **2-field structs (identical types):** Named and unnamed, `From2`, `From<(T,T)>`, and convenience `From1` usage. - * **2-field structs (different types):** Named and unnamed, `From2` and `From<(T1,T2)>` usage. Verify convenience `From1` is **not** generated. - * **3-field structs:** All combinations of identical/different types and their corresponding `FromN` and convenience impls. - * **Generics:** A test for a struct with generic parameters and a `where` clause. - 5. Create two new compile-fail tests: - * `tests/inc/compile_fail/err_from_0_fields.rs`: `#[derive(VariadicFrom)] struct S; let _ : S = from!(1);` - * `tests/inc/compile_fail/err_from_4_fields.rs`: `#[derive(VariadicFrom)] struct S(i32,i32,i32,i32); let _ : S = from!(1,2);` - 6. Update `tests/inc/mod.rs` to include `mod derive_test;`. -* **Increment Verification:** - * Execute `timeout 90 cargo test -p variadic_from --all-targets`. Analyze output for success. The new tests should pass against the fixed macro from Increment 1. -* **Commit Message:** `test(variadic_from): Overhaul test suite for spec compliance` - -##### Increment 3: Refactor `variadic_from` Library and Update `Readme.md` -* **Goal:** Clean up the `variadic_from` library structure and update its `Readme.md` to be accurate, runnable, and informative. -* **Specification Reference:** `spec.md` Sections 4.1, 4.2 -* **Steps:** - 1. Read `module/core/variadic_from/src/lib.rs` and `module/core/variadic_from/src/variadic.rs`. - 2. Move the entire `mod variadic { ... }` block from `src/lib.rs` into the `src/variadic.rs` file. - 3. In `src/lib.rs`, replace the inline module with `pub mod variadic;`. - 4. In `src/lib.rs`, ensure `VariadicFrom` is correctly re-exported in the `exposed` and `prelude` modules. - 5. Fix the codestyle of the `from!` macro definition in `src/variadic.rs` to use newlines for braces. - 6. Read `module/core/variadic_from/Readme.md`. - 7. Rewrite the "Quick Start" and "Expanded Code" examples to be accurate, spec-compliant, and runnable as doc tests (` ```rust `). - 8. Remove the "Debugging" section that mentions the non-existent `#[debug]` attribute. -* **Increment Verification:** - * Execute `timeout 90 cargo test -p variadic_from --doc`. Analyze output for success. -* **Commit Message:** `refactor(variadic_from): Clean up lib, update and fix doc tests` - -##### Increment 4: Finalization -* **Goal:** Perform a final, holistic review and verification of the entire task's output, ensuring all requirements are met and the codebase is clean. -* **Specification Reference:** `spec.md` Section 10 -* **Steps:** - 1. Perform the full `Crate Conformance Check Procedure`. - 2. Self-critique all changes against the `spec.md` and `codestyle.md`. - 3. Ensure no commented-out code or temporary files remain. - 4. Execute `git status` to confirm the working directory is clean. -* **Increment Verification:** - * All steps of the `Crate Conformance Check Procedure` must pass with exit code 0 and no warnings. -* **Commit Message:** `chore(variadic_from): Finalize and verify spec v1.1 implementation` - -### Test Re-enabling Sequence -To systematically re-enable and debug the tests, follow this sequence: - -1. **Re-enable `derive_test.rs` (Basic Functionality):** - * Uncomment `mod derive_test;` in `module/core/variadic_from/tests/inc/mod.rs`. - * Run `cargo test -p variadic_from --test variadic_from_tests`. - * Address any compilation or runtime errors. Pay close attention to `E0282` (type annotations needed) for `from!` macro calls. If these persist, consider adding explicit type annotations to the `let x = from!(...);` lines in `derive_test.rs` as a temporary measure or if the macro cannot infer the type. -2. **Re-enable `err_from_0_fields.rs` (Compile-Fail: 0 Fields):** - * Uncomment `mod err_from_0_fields;` in `module/core/variadic_from/tests/inc/mod.rs`. - * Run `cargo test -p variadic_from --test variadic_from_tests`. - * Verify that it fails with the expected error message: "VariadicFrom can only be derived for structs with named or unnamed fields." -3. **Re-enable `err_from_4_fields.rs` (Compile-Fail: >3 Fields):** - * Uncomment `mod err_from_4_fields;` in `module/core/variadic_from/tests/inc/mod.rs`. - * Run `cargo test -p variadic_from --test variadic_from_tests`. - * Verify that it fails with the expected error message: "Too many arguments". -### Notes & Insights -* **`quote!` Macro Repetition Issues:** Repeatedly encountered `E0277` (`Dlist<...>: ToTokens` not satisfied) and `E0599` (`quote_into_iter` not found) when attempting to use `quote!`'s repetition syntax (`#( ... ),*`) with direct indexing into `Vec` or `Vec<&Type>`. The solution was to extract individual elements into separate local variables before passing them to `quote!`. This indicates `quote!` expects concrete `ToTokens` implementors for each `#var` interpolation, not an iterable that it then tries to index. -* **`FromN` Trait Return Type:** The generated `fromN` methods were initially returning `()` instead of `Self`, leading to `E0053` and `E0308` errors. This was fixed by explicitly adding `-> Self` to the function signatures in the `quote!` macro. -* **Conflicting Blanket Implementations:** The `module/core/variadic_from/src/lib.rs` contained blanket `From1` implementations for tuples and unit types. These conflicted with the specific `FromN` implementations generated by the `VariadicFrom` derive macro, causing `E0119` (conflicting implementations). The resolution was to remove these blanket implementations, as the derive macro now handles all necessary `From` and `FromN` implementations. -* **Generics Propagation:** Initial attempts to generate `impl` blocks for generic structs did not correctly propagate the generic parameters and `where` clauses, leading to `E0412` (`cannot find type T in this scope`) and `E0107` (`missing generics for struct`). This was resolved by storing `&syn::Generics` in `VariadicFromContext` and using `generics.split_for_impl()` to correctly apply `impl_generics`, `ty_generics`, and `where_clause` to the generated `impl` blocks. -* **`from!` Macro Type Inference:** After fixing the above, `E0282` (`type annotations needed`) errors appeared for `from!` macro calls. This is likely due to the compiler's inability to infer the target type when multiple `FromN` traits might apply, especially after removing the blanket implementations. This will need to be addressed by either adding explicit type annotations in the tests or by refining the `from!` macro's dispatch if possible. -* **Compile-Fail Tests:** `err_from_0_fields.rs` and `err_from_4_fields.rs` are correctly failing as expected, confirming the macro's validation logic for field counts. -### Changelog -* [New Plan | 2025-07-05 23:13 UTC] Created a new, comprehensive plan to address spec compliance, test suite overhaul, and documentation accuracy for `variadic_from` and `variadic_from_meta`. -* [2025-07-06] Refactored `variadic_from_meta` to align with spec v1.1, including `Cargo.toml` updates, modular code generation, delegation, conditional convenience impls, and absolute paths.

Introduction & Core Concepts + +**Design Focus: `Strategic Context`** + +This document is the single source of truth for the `unilang` framework. It defines the language, its components, and the responsibilities of its constituent crates. + +#### 0.1. Scope: A Multi-Crate Framework + +The Unilang specification governs a suite of related crates that work together to provide the full framework functionality. This document is the canonical specification for all of them. The primary crates are: + +* **`unilang`**: The core framework crate that orchestrates parsing, semantic analysis, execution, and modality management. +* **`unilang_instruction_parser`**: A dedicated, low-level crate responsible for the lexical and syntactic analysis of the `unilang` command language (implements Section 2 of this spec). +* **`unilang_meta`**: A companion crate providing procedural macros to simplify compile-time command definition (implements parts of Section 3.4). + +#### 0.2. Goals of `unilang` + +`unilang` provides a unified way to define command-line utility interfaces once, automatically enabling consistent interaction across multiple modalities such as CLI, GUI, TUI, and Web APIs. The core goals are: + +1. **Consistency:** A single way to define commands and their arguments, regardless of how they are presented or invoked. +2. **Discoverability:** Easy ways for users and systems to find available commands and understand their usage. +3. **Flexibility:** Support for various methods of command definition (compile-time, run-time, declarative, procedural). +4. **Extensibility:** Provide structures that enable an integrator to build an extensible system with compile-time `Extension Module`s and run-time command registration. +5. **Efficiency:** Support for efficient parsing and command dispatch. The architecture **must** support near-instantaneous lookup for large sets (100,000+) of statically defined commands by performing maximum work at compile time. +6. **Interoperability:** Standardized representation for commands, enabling integration with other tools or web services, including auto-generation of WEB endpoints. +7. **Robustness:** Clear error handling and validation mechanisms. +8. **Security:** Provide a framework for defining and enforcing secure command execution. + +#### 0.3. System Actors + +* **`Integrator (Developer)`**: The primary human actor who uses the `unilang` framework to build a `utility1` application. They define commands, write routines, and configure the system. +* **`End User`**: A human actor who interacts with the compiled `utility1` application through one of its exposed `Modalities` (e.g., CLI, GUI). +* **`Operating System`**: A system actor that provides the execution environment, including the CLI shell, file system, and environment variables that `utility1` consumes for configuration. +* **`External Service`**: Any external system (e.g., a database, a web API, another process) that a command `Routine` might interact with. + +#### 0.4. Key Terminology (Ubiquitous Language) + +* **`unilang`**: This specification and the core framework crate. +* **`utility1`**: A generic placeholder for the primary application that implements and interprets `unilang`. +* **`Command Lexicon`**: The complete set of all commands available to `utility1` at any given moment. +* **`Command Registry`**: The runtime data structure that implements the `Command Lexicon`. +* **`Command Manifest`**: An external file (e.g., in YAML or JSON format) that declares `CommandDefinition`s for runtime loading. +* **`Command`**: A specific action that can be invoked, identified by its `FullName`. +* **`FullName`**: The complete, unique, dot-separated path identifying a command (e.g., `.files.copy`). +* **`Namespace`**: A logical grouping for commands and other namespaces. +* **`CommandDefinition` / `ArgumentDefinition`**: The canonical metadata for a command or argument. +* **`Routine`**: The executable code (handler function) associated with a command. Its signature is `fn(VerifiedCommand, ExecutionContext) -> Result`. +* **`Modality`**: A specific way of interacting with `utility1` (e.g., CLI, GUI). +* **`parser::GenericInstruction`**: The output of the `unilang_instruction_parser`. +* **`VerifiedCommand`**: A command that has passed semantic analysis and is ready for execution. * **`ExecutionContext`**: An object providing routines with access to global settings and services. +* **`OutputData` / `ErrorData`**: Standardized structures for returning success or failure results. + +--- + +### 1. Architectural Mandates & Design Principles + +This section outlines the non-negotiable architectural rules and mandatory dependencies for the `unilang` ecosystem. Adherence to these principles is required to ensure consistency, maintainability, and correctness across the framework. + +#### 1.1. Parser Implementation (`unilang_instruction_parser`) + +* **Mandate:** The `unilang_instruction_parser` crate **must not** implement low-level string tokenization (splitting) logic from scratch. It **must** use the `strs_tools` crate as its core tokenization engine. +* **Rationale:** This enforces a clean separation of concerns. `strs_tools` is a dedicated, specialized tool for string manipulation. By relying on it, `unilang_instruction_parser` can focus on its primary responsibility: syntactic analysis of the token stream, not the raw tokenization itself. + +##### Overview of `strs_tools` + +`strs_tools` is a utility library for advanced string splitting and tokenization. Its core philosophy is to provide a highly configurable, non-allocating iterator over a string, giving the consumer fine-grained control over how the string is divided. -#### 1.3. System Actors -* **`Integrator (Developer)`**: A human actor responsible for defining commands, writing routines, and building the final `utility1`. -* **`End User`**: A human actor who interacts with the compiled `utility1` through a specific `Modality`. -* **`Operating System`**: A system actor that provides the execution environment, including the CLI shell and file system. -* **`External Service`**: Any external system (e.g., a database, a web API) that a `Routine` might interact with. - -#### 1.4. User Stories & Journeys -* **Happy Path - Executing a File Read Command:** - 1. The **`Integrator`** defines a `.file.cat` **`Command`** with one mandatory `path` argument of **`Kind::Path`**. They implement a **`Routine`** that reads a file's content and returns it in **`OutputData`**. - 2. The **`End User`** opens their CLI shell and types the **`Command Expression`**: `utility1 .file.cat path::/home/user/document.txt`. - 3. The **`unilang`** framework's parser correctly identifies the command path and the named argument, producing a **`parser::GenericInstruction`**. - 4. The semantic analyzer validates the instruction against the command registry and produces a **`VerifiedCommand`**. - 5. The **`Interpreter`** invokes the associated **`Routine`**, which interacts with the **`Operating System`**'s file system, reads the file, and returns the content successfully. - 6. The **`Interpreter`** formats the **`OutputData`** and prints the file's content to the **`End User`**'s console. - -* **Security Path - Handling a Sensitive Argument:** - 1. The **`Integrator`** defines a `.login` **`Command`** with a `password` argument marked as a **`Sensitive Argument`**. - 2. The **`End User`** invokes the command interactively. The `utility1` CLI **`Modality`** detects the `sensitive` flag and masks the user's input. - 3. The `password` **`Value`** is passed through the system but is never printed to logs due to the `sensitive` flag. - 4. The **`Routine`** uses the password to authenticate against an **`External Service`**. +* **Key Principle:** The library intentionally does **not** interpret escape sequences (e.g., `\"`). It provides raw string slices, leaving the responsibility of unescaping to the consumer (`unilang_instruction_parser`). +* **Usage Flow:** The typical workflow involves using a fluent builder pattern: + 1. Call `strs_tools::string::split::split()` to get a builder (`SplitOptionsFormer`). + 2. Configure it with methods like `.delimeter()`, `.quoting(true)`, etc. + 3. Call `.perform()` to get a `SplitIterator`. + 4. Iterate over the `Split` items, which contain the string slice and metadata about the token. + +* **Recommended Components:** + * **`strs_tools::string::split::split()`**: The main entry point function that returns the builder. + * **`SplitOptionsFormer`**: The builder for setting options. Key methods include: + * `.delimeter( &[" ", "::", ";;"] )`: To define what separates tokens. + * `.quoting( true )`: To make the tokenizer treat quoted sections as single tokens. + * `.preserving_empty( false )`: To ignore empty segments resulting from consecutive delimiters. + * **`SplitIterator`**: The iterator produced by the builder. + * **`Split`**: The struct yielded by the iterator, containing the `string` slice, its `typ` (`Delimiter` or `Delimited`), and its `start`/`end` byte positions in the original source. + +#### 1.2. Macro Implementation (`unilang_meta`) + +* **Mandate:** The `unilang_meta` crate **must** prefer using the `macro_tools` crate as its primary dependency for all procedural macro development. Direct dependencies on `syn`, `quote`, or `proc-macro2` should be avoided. +* **Rationale:** `macro_tools` not only re-exports these three essential crates but also provides a rich set of higher-level abstractions and utilities. Using it simplifies parsing, reduces boilerplate code, improves error handling, and leads to more readable and maintainable procedural macros. + + > ❌ **Bad** (`Cargo.toml` with direct dependencies) + > ```toml + > [dependencies] + > syn = { version = "2.0", features = ["full"] } + > quote = "1.0" + > proc-macro2 = "1.0" + > ``` + + > ✅ **Good** (`Cargo.toml` with `macro_tools`) + > ```toml + > [dependencies] + > macro_tools = "0.57" + > ``` + +##### Recommended `macro_tools` Components + +To effectively implement `unilang_meta`, the following components from `macro_tools` are recommended: + +* **Core Re-exports (`syn`, `quote`, `proc-macro2`):** Use the versions re-exported by `macro_tools` for guaranteed compatibility. +* **Diagnostics (`diag` module):** Essential for providing clear, professional-grade error messages to the `Integrator`. + * **`syn_err!( span, "message" )`**: The primary tool for creating `syn::Error` instances with proper location information. + * **`return_syn_err!(...)`**: A convenient macro to exit a parsing function with an error. +* **Attribute Parsing (`attr` and `attr_prop` modules):** The main task of `unilang_meta` is to parse attributes like `#[unilang::command(...)]`. These modules provide reusable components for this purpose. + * **`AttributeComponent`**: A trait for defining a parsable attribute (e.g., `unilang::command`). + * **`AttributePropertyComponent`**: A trait for defining a property within an attribute (e.g., `name = "..."`). + * **`AttributePropertySyn` / `AttributePropertyBoolean`**: Reusable structs for parsing properties that are `syn` types (like `LitStr`) or booleans. +* **Item & Struct Parsing (`struct_like`, `item_struct` modules):** Needed to analyze the Rust code (struct or function) to which the macro is attached. + * **`StructLike`**: A powerful enum that can represent a `struct`, `enum`, or `unit` struct, simplifying the analysis logic. +* **Generics Handling (`generic_params` module):** If commands can be generic, this module is indispensable. + * **`GenericsRef`**: A wrapper that provides convenient methods for splitting generics into parts needed for `impl` blocks and type definitions. +* **General Utilities:** + * **`punctuated`**: Helpers for working with `syn::punctuated::Punctuated` collections. + * **`ident`**: Utilities for creating and manipulating identifiers, including handling of Rust keywords. + +#### 1.3. Framework Parsing (`unilang`) + +* **Mandate:** The `unilang` core framework **must** delegate all command expression parsing to the `unilang_instruction_parser` crate. It **must not** contain any of its own CLI string parsing logic. +* **Rationale:** This enforces the architectural separation between syntactic analysis (the responsibility of `unilang_instruction_parser`) and semantic analysis (the responsibility of `unilang`). This modularity makes the system easier to test, maintain, and reason about. --- -### 2. Formal Framework Specification - -This section provides the complete, formal definition of the `unilang` language, its components, and its processing model. It is the single source of truth for all `Integrator`s. - -#### 2.1. Introduction & Core Concepts -* **2.1.1. Goals**: Consistency, Discoverability, Flexibility, Extensibility, Efficiency, Interoperability, Robustness, and Security. -* **2.1.2. Versioning**: This specification follows SemVer 2.0.0. - -#### 2.2. Language Syntax and Processing -The canonical parser for the `unilang` language is the **`unilang_instruction_parser`** crate. The legacy `unilang::parsing` module is deprecated and must be removed. - -* **2.2.1. Unified Processing Pipeline**: The interpretation of user input **must** proceed through the following pipeline: - 1. **Input (`&str` or `&[&str]`)** is passed to the `unilang_instruction_parser::Parser`. - 2. **Syntactic Analysis**: The parser produces a `Vec`. - 3. **Semantic Analysis**: The `unilang::SemanticAnalyzer` consumes the `Vec` and, using the `CommandRegistry`, produces a `Vec`. - 4. **Execution**: The `unilang::Interpreter` consumes the `Vec` and executes the associated `Routine`s. - -* **2.2.2. Syntax**: The CLI syntax is defined by the grammar in **Appendix A.2**. It supports command paths, positional arguments, named arguments (`key::value`), quoted values, command separators (`;;`), and a help operator (`?`). - -#### 2.3. Command and Argument Definition -* **2.3.1. Namespaces**: Namespaces provide a hierarchical organization for commands. A command's `FullName` (e.g., `.files.copy`) is constructed by joining its `path` and `name`. The `CommandRegistry` must resolve commands based on this hierarchy. - -* **2.3.2. `CommandDefinition` Anatomy**: - | Field | Type | Description | - | :--- | :--- | :--- | - | `path` | `Vec` | The namespace path segments (e.g., `["files"]`). | - | `name` | `String` | The final command name segment (e.g., `"copy"`). | - | `hint` | `String` | Optional. A human-readable explanation. | - | `arguments` | `Vec` | Optional. A list of arguments the command accepts. | - | `permissions` | `Vec` | Optional. A list of permission identifiers required for execution. | - | `status` | `Enum` | Optional. Lifecycle state (`Experimental`, `Stable`, `Deprecated`). | - | `routine_link` | `Option` | Optional. A link to the executable routine for runtime-loaded commands. | - | `http_method_hint`| `String` | Optional. A suggested HTTP method for Web API modality. | - | `idempotent` | `Boolean` | Optional. If `true`, the command can be safely executed multiple times. | - | `examples` | `Vec` | Optional. Illustrative usage examples for help text. | - | `version` | `String` | Optional. The SemVer version of the individual command. | - -* **2.3.3. `ArgumentDefinition` Anatomy**: - | Field | Type | Description | - | :--- | :--- | :--- | - | `name` | `String` | Mandatory. The unique identifier for the argument (e.g., `src`). | - | `hint` | `String` | Optional. A human-readable description. | - | `kind` | `Kind` | Mandatory. The data type of the argument's value. | - | `optional` | `bool` | Optional (Default: `false`). If `true`, the argument may be omitted. | - | `default_value` | `Option` | Optional. A value to use if an optional argument is not provided. | - | `is_default_arg`| `bool` | Optional (Default: `false`). If `true`, its value can be provided positionally. | - | `multiple` | `bool` | Optional (Default: `false`). If `true`, the argument can be specified multiple times. | - | `sensitive` | `bool` | Optional (Default: `false`). If `true`, the value must be protected. | - | `validation_rules`| `Vec` | Optional. Custom validation logic (e.g., `"min:0"`). | - | `aliases` | `Vec` | Optional. A list of alternative short names. | - | `tags` | `Vec` | Optional. Keywords for UI grouping (e.g., "Basic", "Advanced"). | - -* **2.3.4. Data Types (`Kind`)**: The `kind` attribute specifies the expected data type. - * **Primitives**: `String`, `Integer`, `Float`, `Boolean`. - * **Semantic Primitives**: `Path`, `File`, `Directory`, `Enum(Vec)`, `Url`, `DateTime`, `Pattern`. - * **Collections**: `List(Box)`, `Map(Box, Box)`. - * **Complex**: `JsonString`, `Object`. - * **Streaming**: `InputStream`, `OutputStream`. - * **Extensibility**: The system must be extensible to support custom types. - -#### 2.4. Cross-Cutting Concerns -* **2.4.1. Error Handling (`ErrorData`)**: The standardized error structure must be used. - ```json - { - "code": "ErrorCodeIdentifier", - "message": "Human-readable error message.", - "details": { - "argument_name": "src", - "location_in_input": { "source_type": "single_string", "start_offset": 15, "end_offset": 20 } - }, - "origin_command": ".files.copy" - } - ``` -* **2.4.2. Standard Output (`OutputData`)**: The standardized output structure must be used. - ```json - { - "payload": "Any", - "metadata": { "count": 10 }, - "output_type_hint": "application/json" - } - ``` -* **2.4.3. Extensibility Model**: The framework supports a hybrid model. **`Extension Module`s** can provide modalities, core commands, and custom types at compile-time. New **`CommandDefinition`s** can be registered at run-time. See **Appendix A.3** for a conceptual outline. +### 2. Language Syntax & Processing (CLI) + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang_instruction_parser` crate** + +This section defines the public contract for the CLI modality's syntax. The `unilang_instruction_parser` crate is the reference implementation for this section. + +#### 2.1. Unified Processing Pipeline + +The interpretation of a `unilang` CLI string by `utility1` **must** proceed through the following conceptual phases: + +1. **Phase 1: Syntactic Analysis (String to `GenericInstruction`)** + * **Responsibility:** `unilang_instruction_parser` crate. + * **Process:** The parser consumes the input and, based on the `unilang` grammar (Appendix A.2), identifies command paths, positional arguments, named arguments (`key::value`), and operators (`;;`, `?`). + * **Output:** A `Vec`. This phase has no knowledge of command definitions; it is purely syntactic. + +2. **Phase 2: Semantic Analysis (`GenericInstruction` to `VerifiedCommand`)** + * **Responsibility:** `unilang` crate. + * **Process:** Each `GenericInstruction` is validated against the `CommandRegistry`. The command name is resolved, arguments are bound to their definitions, types are checked, and validation rules are applied. + * **Output:** A `Vec`. + +3. **Phase 3: Execution** + * **Responsibility:** `unilang` crate's Interpreter. + * **Process:** The interpreter invokes the `Routine` for each `VerifiedCommand`, passing it the validated arguments and execution context. + * **Output:** A `Result` for each command, which is then handled by the active `Modality`. + +#### 2.2. Naming Conventions + +To ensure consistency across all `unilang`-based utilities, the following naming conventions **must** be followed: + +* **Command & Namespace Segments:** Must consist of lowercase alphanumeric characters (`a-z`, `0-9`) and underscores (`_`). Dots (`.`) are used exclusively as separators. Example: `.system.info`, `.file_utils.read_all`. +* **Argument Names & Aliases:** Must consist of lowercase alphanumeric characters and may use `kebab-case` for readability. Example: `input-file`, `force`, `user-name`. + +#### 2.3. Command Expression + +A `command_expression` can be one of the following: +* **Full Invocation:** `[namespace_path.]command_name [argument_value...] [named_argument...]` +* **Help Request:** `[namespace_path.][command_name] ?` or `[namespace_path.]?` -#### 2.5. Interpreter / Execution Engine -The Interpreter is the component responsible for taking a `VerifiedCommand`, retrieving its `Routine` from the registry, preparing the `ExecutionContext`, and invoking the `Routine`. It handles the `Result` from the routine, passing `OutputData` or `ErrorData` to the active `Modality` for presentation. +#### 2.4. Parsing Rules and Precedence + +To eliminate ambiguity, the parser **must** adhere to the following rules in order. + +* **Rule 0: Whitespace Separation** + * Whitespace characters (spaces, tabs) serve only to separate tokens. Multiple consecutive whitespace characters are treated as a single separator. Whitespace is not part of a token's value unless it is inside a quoted string. + +* **Rule 1: Command Path Identification** + * The **Command Path** is the initial sequence of tokens that identifies the command to be executed. + * A command path consists of one or more **segments**. + * Segments **must** be separated by a dot (`.`). Whitespace around the dot is ignored. + * A segment **must** be a valid identifier according to the `Naming Conventions` (Section 2.2). + * The command path is the longest possible sequence of dot-separated identifiers at the beginning of an expression. + +* **Rule 2: End of Command Path & Transition to Arguments** + * The command path definitively ends, and argument parsing begins, upon encountering the **first token** that is not a valid, dot-separated identifier segment. + * This transition is triggered by: + * A named argument separator (`::`). + * A quoted string (`"..."` or `'...'`). + * The help operator (`?`). + * Any other token that does not conform to the identifier naming convention. + * **Example:** In `utility1 .files.copy --force`, the command path is `.files.copy`. The token `--force` is not a valid segment, so it becomes the first positional argument. + +* **Rule 3: Dot (`.`) Operator Rules** + * **Leading Dot:** A single leading dot at the beginning of a command path (e.g., `.files.copy`) is permitted and has no semantic meaning. It is consumed by the parser and does not form part of the command path's segments. + * **Trailing Dot:** A trailing dot after the final command segment (e.g., `.files.copy.`) is a **syntax error**. + +* **Rule 4: Help Operator (`?`)** + * The `?` operator marks the entire instruction for help generation. + * It **must** be the final token in a command expression. + * It **may** be preceded by arguments. If it is, this implies a request for contextual help. The `unilang` framework (not the parser) is responsible for interpreting this context. + * **Valid:** `.files.copy ?` + * **Valid:** `.files.copy from::/src ?` + * **Invalid:** `.files.copy ? from::/src` + +* **Rule 5: Argument Types** + * **Positional Arguments:** Any token that follows the command path and is not a named argument is a positional argument. + * **Named Arguments:** Any pair of tokens matching the `name::value` syntax is a named argument. The `value` can be a single token or a quoted string. + +--- + +### 3. Core Definitions + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate** + +This section defines the core data structures that represent commands, arguments, and namespaces. These structures form the primary API surface for an `Integrator`. + +#### 3.1. `NamespaceDefinition` Anatomy + +A namespace is a first-class entity to improve discoverability and help generation. + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The unique, dot-separated `FullName` of the namespace (e.g., `.files`, `.system.internal`). | +| `hint` | `String` | No | A human-readable explanation of the namespace's purpose. | + +#### 3.2. `CommandDefinition` Anatomy + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The final segment of the command's name (e.g., `copy`). The full path is derived from its registered namespace. | +| `namespace` | `String` | Yes | The `FullName` of the parent namespace this command belongs to (e.g., `.files`). | +| `hint` | `String` | No | A human-readable explanation of the command's purpose. | +| `arguments` | `Vec` | No | A list of arguments the command accepts. | +| `routine` | `Routine` | Yes (for static) | A direct reference to the executable code (e.g., a function pointer). | +| `routine_link` | `String` | No | For commands loaded from a `Command Manifest`, this is a string that links to a pre-compiled, registered routine. | +| `permissions` | `Vec` | No | A list of permission identifiers required for execution. | +| `status` | `Enum` | No (Default: `Stable`) | Lifecycle state: `Experimental`, `Stable`, `Deprecated`. | +| `deprecation_message` | `String` | No | If `status` is `Deprecated`, explains the reason and suggests alternatives. | +| `http_method_hint`| `String` | No | A suggested HTTP method (`GET`, `POST`, etc.) for the Web API modality. | +| `idempotent` | `bool` | No (Default: `false`) | If `true`, the command can be safely executed multiple times. | +| `examples` | `Vec` | No | Illustrative usage examples for help text. | +| `version` | `String` | No | The SemVer version of the individual command (e.g., "1.0.2"). | +| `tags` | `Vec` | No | Keywords for grouping or filtering commands (e.g., "filesystem", "networking"). | + +#### 3.3. `ArgumentDefinition` Anatomy + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The unique (within the command), case-sensitive identifier (e.g., `src`). | +| `hint` | `String` | No | A human-readable description of the argument's purpose. | +| `kind` | `Kind` | Yes | The data type of the argument's value. | +| `optional` | `bool` | No (Default: `false`) | If `true`, the argument may be omitted. | +| `default_value` | `Option` | No | A string representation of the value to use if an optional argument is not provided. It will be parsed on-demand. | +| `is_default_arg`| `bool` | No (Default: `false`) | If `true`, its value can be provided positionally in the CLI. | +| `multiple` | `bool` | No (Default: `false`) | If `true`, the argument can be specified multiple times. | +| `sensitive` | `bool` | No (Default: `false`) | If `true`, the value must be protected (masked in UIs, redacted in logs). | +| `validation_rules`| `Vec` | No | Custom validation logic (e.g., `"min:0"`, `"regex:^.+$"`). | +| `aliases` | `Vec` | No | A list of alternative short names (e.g., `s` for `source`). | +| `tags` | `Vec` | No | Keywords for UI grouping (e.g., "Basic", "Advanced"). | +| `interactive` | `bool` | No (Default: `false`) | If `true`, modalities may prompt for input if the value is missing. | + +#### 3.4. Methods of Command Specification + +The methods for defining commands. The "Compile-Time Declarative" method is primarily implemented by the `unilang_meta` crate. + +1. **Compile-Time Declarative (via `unilang_meta`):** Using procedural macros on Rust functions or structs to generate `CommandDefinition`s at compile time. +2. **Run-Time Procedural:** Using a builder API within `utility1` to construct and register commands dynamically. +3. **External Definition:** Loading `CommandDefinition`s from external files (e.g., YAML, JSON) at compile-time or run-time. + +#### 3.5. The Command Registry + +**Design Focus: `Internal Design`** +**Primary Implementor: `unilang` crate** + +The `CommandRegistry` is the runtime data structure that stores the entire `Command Lexicon`. To meet the high-performance requirement for static commands while allowing for dynamic extension, it **must** be implemented using a **Hybrid Model**. + +* **Static Registry:** + * **Implementation:** A **Perfect Hash Function (PHF)** data structure. + * **Content:** Contains all commands, namespaces, and routines that are known at compile-time. + * **Generation:** The PHF **must** be generated by `utility1`'s build process (e.g., in `build.rs`) from all compile-time command definitions. This ensures that the cost of building the lookup table is paid during compilation, not at application startup. +* **Dynamic Registry:** + * **Implementation:** A standard `HashMap`. + * **Content:** Contains commands and namespaces that are added at runtime (e.g., from a `Command Manifest`). +* **Lookup Precedence:** When resolving a command `FullName`, the `CommandRegistry` **must** first query the static PHF. If the command is not found, it must then query the dynamic `HashMap`. --- -### 3. Project Requirements & Conformance - -#### 3.1. Roadmap to Conformance -To align the current codebase with this specification, the following high-level tasks must be completed: -1. **Deprecate Legacy Parser**: Remove the `unilang::parsing` module and all its usages from the `unilang` crate. -2. **Integrate `unilang_instruction_parser`**: Modify the `unilang` crate's `SemanticAnalyzer` and primary execution flow to consume `Vec` from the `unilang_instruction_parser` crate. -3. **Enhance Data Models**: Update the `CommandDefinition` and `ArgumentDefinition` structs in `unilang/src/data.rs` to include all fields defined in Sections 2.3.2 and 2.3.3 of this specification. -4. **Update `unilang_cli`**: Refactor `src/bin/unilang_cli.rs` to use the new, unified processing pipeline. - -#### 3.2.

Global Arguments & Configuration + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate** + +This section defines how an `Integrator` configures `utility1` and how an `End User` can override that configuration. + +#### 4.1. `GlobalArgumentDefinition` Anatomy + +The `Integrator` **must** define their global arguments using this structure, which can then be registered with `utility1`. + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The unique name of the global argument (e.g., `output-format`). | +| `hint` | `String` | No | A human-readable description. | +| `kind` | `Kind` | Yes | The data type of the argument's value. | +| `env_var` | `String` | No | The name of an environment variable that can set this value. | + +#### 4.2.

System-wide configuration file (e.g., `/etc/utility1/config.toml`). +3. User-specific configuration file (e.g., `~/.config/utility1/config.toml`). +4. Project-specific configuration file (e.g., `./.utility1.toml`). +5. Environment variables (as defined in `GlobalArgumentDefinition.env_var`). +6.

GUI (Graphical User Interface):** A graphical interface with forms and widgets generated from command definitions. +* **6.4. WEB Endpoints:** + * **Goal:** Automatically generate a web API from `unilang` command specifications. + * **Mapping:** A command `.namespace.command` maps to an HTTP path like `/api/v1/namespace/command`. + * **Serialization:** Arguments are passed as URL query parameters (`GET`) or a JSON body (`POST`/`PUT`). `OutputData` and `ErrorData` are returned as JSON. + * **Discoverability:** An endpoint (e.g., `/openapi.json`) **must** be available to generate an OpenAPI v3+ specification. The content of this specification is derived directly from the `CommandDefinition`, `ArgumentDefinition`, and `NamespaceDefinition` metadata. + +--- + +### 7. Cross-Cutting Concerns + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate** + +This section defines framework-wide contracts for handling common concerns like errors and security. + +#### 7.1. Error Handling (`ErrorData`) + +Routines that fail **must** return an `ErrorData` object. The `code` field should use a standard identifier where possible. + +* **Standard Codes:** `UNILANG_COMMAND_NOT_FOUND`, `UNILANG_ARGUMENT_INVALID`, `UNILANG_ARGUMENT_MISSING`, `UNILANG_TYPE_MISMATCH`, `UNILANG_VALIDATION_RULE_FAILED`, `UNILANG_PERMISSION_DENIED`, `UNILANG_EXECUTION_ERROR`, `UNILANG_IO_ERROR`, `UNILANG_INTERNAL_ERROR`. +* **New Code for External Failures:** `UNILANG_EXTERNAL_DEPENDENCY_ERROR` - To be used when a routine fails due to an error from an external service (e.g., network timeout, API error response). + +```json +{ + "code": "ErrorCodeIdentifier", + "message": "Human-readable error message.", + "details": { + "argument_name": "src", + "location_in_input": { "source_type": "single_string", "start_offset": 15, "end_offset": 20 } + }, + "origin_command": ".files.copy" +} +``` + +#### 7.2. Standard Output (`OutputData`) + +Successful routines **must** return an `OutputData` object. + +```json +{ + "payload": "Any", + "metadata": { "count": 10, "warnings": [] }, + "output_type_hint": "application/json" +} +``` + +#### 7.3. Security + +* **Permissions:** The `permissions` field on a `CommandDefinition` declares the rights needed for execution. The `utility1` `Interpreter` is responsible for checking these. +* **Sensitive Data:** Arguments marked `sensitive: true` **must** be masked in UIs and redacted from logs. + +#### 7.4. Extensibility Model + +* **Compile-Time `Extension Module`s:** Rust crates that can provide a suite of components to `utility1`. An extension module **should** include a manifest file (e.g., `unilang-module.toml`) to declare the components it provides. These components are compiled into the **Static Registry (PHF)**. +* **Run-Time `Command Manifest`s:** `utility1` **must** provide a mechanism to load `CommandDefinition`s from external `Command Manifest` files (e.g., YAML or JSON) at runtime. These commands are registered into the **Dynamic Registry (HashMap)**. The `routine_link` field in their definitions is used to associate them with pre-compiled functions. + +--- + +### 8. Project Management + +**Design Focus: `Strategic Context`** + +This section contains meta-information about the project itself. + +#### 8.1. Success Metrics + +* **Performance:** For a `utility1` application with 100,000 statically compiled commands, the p99 latency for resolving a command `FullName` in the `CommandRegistry` **must** be less than 1 millisecond on commodity hardware. +* **Adoption:** The framework is considered successful if it is used to build at least three distinct `utility1` applications with different modalities. + +#### 8.2. Out of Scope + +The `unilang` framework is responsible for the command interface, not the business logic itself. The following are explicitly out of scope: + +* **Transactional Guarantees:** The framework does not provide built-in transactional logic for command sequences. If a command in a `;;` sequence fails, the framework will not automatically roll back the effects of previous commands. +* **Inter-Command State Management:** The framework does not provide a mechanism for one command to pass complex state to the next, other than through external means (e.g., environment variables, files) managed by the `Integrator`. +* **Business Logic Implementation:** The framework provides the `Routine` execution shell, but the logic inside the routine is entirely the `Integrator`'s responsibility. + +#### 8.3. Open Questions + +This section tracks critical design decisions that are not yet finalized. + +1. **Runtime Routine Linking:** What is the precise mechanism for resolving a `routine_link` string from a `Command Manifest` to a callable function pointer at runtime? Options include a name-based registry populated at startup or dynamic library loading (e.g., via `libloading`). This needs to be defined. +2. **Custom Type Registration:** What is the API and process for an `Integrator` to define a new custom `Kind` and register its associated parsing and validation logic with the framework? + +--- + +### 9. Interpreter / Execution Engine + +**Design Focus: `Internal Design`** +**Primary Implementor: `unilang` crate** + +The Interpreter is the internal `unilang` component responsible for orchestrating command execution. Its existence and function are critical, but its specific implementation details are not part of the public API. + +1. **Routine Invocation:** For each `VerifiedCommand`, the Interpreter retrieves the linked `Routine` from the `CommandRegistry`. +2. **Context Preparation:** It prepares and passes the `VerifiedCommand` object and the `ExecutionContext` object to the `Routine`. +3. **Result Handling:** It receives the `Result` from the `Routine` and passes it to the active `Modality` for presentation. +4. **Sequential Execution:** It executes commands from a `;;` sequence in order, respecting the `on_error` global argument policy. + +--- + +### 10. Crate-Specific Responsibilities + +**Design Focus: `Strategic Context`** + +This section clarifies the role of each crate in implementing this specification. + +#### 10.1. `unilang` (Core Framework) + +* **Role:** The central orchestrator. +* **Responsibilities:** + * **Mandate:** Must use `unilang_instruction_parser` for all syntactic analysis. + * Implements the **Hybrid `CommandRegistry`** (PHF for static, HashMap for dynamic). + * Provides the build-time logic for generating the PHF from compile-time definitions. + * Implements the `SemanticAnalyzer` (Phase 2) and `Interpreter` (Phase 3). + * Defines all core data structures (`CommandDefinition`, `ArgumentDefinition`, etc.). + * Implements the Configuration Management system. + +#### 10.2. `unilang_instruction_parser` (Parser) + +* **Role:** The dedicated lexical and syntactic analyzer. +* **Responsibilities:** + * **Mandate:** Must use the `strs_tools` crate for tokenization. + * Provides the reference implementation for **Section 2: Language Syntax & Processing**. + * Parses a raw string or slice of strings into a `Vec`. + * **It has no knowledge of command definitions, types, or semantics.** + +#### 10.3. `unilang_meta` (Macros) + +* **Role:** A developer-experience enhancement for compile-time definitions. +* **Responsibilities:** + * **Mandate:** Must use the `macro_tools` crate for procedural macro implementation. + * Provides procedural macros (e.g., `#[unilang::command]`) that generate `CommandDefinition` structures. + * These generated definitions are the primary input for the **PHF generation** step in `utility1`'s build process. + +--- + +### 11.

BNF or Formal Grammar for CLI Syntax (Simplified) +##### A.2. BNF or Formal Grammar for CLI Syntax (Simplified & Revised) -This is a simplified, illustrative Backus-Naur Form (BNF) style grammar. A full grammar would be more complex, especially regarding value parsing and shell quoting. This focuses on the `unilang` structure. +This grammar reflects the strict parsing rules defined in Section 2.5. ```bnf ::= - ::= | "" - ::= - ::= | "" - - ::= - ::= | "" - ::= ";;" - - ::= - | - | (* . or .? *) + ::= + ::= ";;" | "" - ::= - ::= | "" - ::= "." "." (* e.g., .files.utils. *) - ::= (* e.g. .files. *) - ::= "." + ::= + | - ::= - ::= "." | "" - ::= (* command or namespace segment: lowercase alphanumeric + underscore *) + ::= + ::= "." | "" + ::= + ::= "." | "" - ::= (* The full path-like name of the command *) + ::= | "" + ::= | + ::= + ::= | "" + ::= | - ::= | "" - ::= - ::= | "" - - ::= | - - ::= "::" - ::= (* kebab-case or snake_case *) - - ::= (* positional, parsed as default arg if one is defined *) - - ::= | -(* Actual value parsing is type-dependent and complex, involving list/map separators, etc. *) -(* would be [a-z0-9_]+ *) -(* would be [a-z0-9_-]+ *) -(* handles spaces and special characters. Unescaped content is used. *) + ::= + ::= "::" + ::= | ::= | "" ::= "?" ``` -**Notes on this BNF:** - -* It's high-level and conceptual. -* `utility_name` is the literal name of the utility (e.g., `utility1`). -* `` and `` need precise definitions based on allowed characters (Section 2.3.1). -* `` parsing is the most complex part and is abstracted here. It represents the unescaped content after initial lexing and quote processing. -* Shell quoting and escaping are handled by the shell before `utility1` receives the arguments. `unilang`'s parser then handles its own quoting rules. - -**Note on Applying Grammar to Dual Input Types:** +#### Appendix B: Command Syntax Cookbook -This BNF describes the logical structure of a `unilang` command expression. -* When parsing a **single string input**, the parser attempts to match this grammar directly against the character stream. -* When parsing a **slice of strings input** (pre-tokenized by the shell), the parser consumes these strings sequentially. Each string (or parts of it, if a string contains multiple `unilang` elements like `name::value`) is then matched against the grammar rules. For instance, one string from the slice might be an ``, the next might be `::` (if the shell separated it), and the next an ``. Or a single string from the slice might be `name::value` which the `unilang` parser then further decomposes. The parser must be able to stitch these segments together to form complete `unilang` syntactic structures as defined by the grammar. +This appendix provides a comprehensive set of practical examples for the `unilang` CLI syntax. -#### A.3. Component Registration (Conceptual Outline for Hybrid Model) +##### B.1. Basic Commands -This appendix outlines the conceptual mechanisms for how `unilang` components are registered within `utility1`, covering both compile-time contributions from **`Extension Module`s** and run-time command registration. The `noun_verb` convention is used for conceptual API method names that `utility1` might expose for run-time operations. - -**1. Compile-Time Component Registration (Modalities, Core Commands from `Extension Module`s, Types)** - -`Extension Module`s providing modalities, core commands, or custom types need to make their definitions available to `utility1`'s central registries at compile time. - -* **A. Information Required for Modality Registration (Compile-Time Only via `Extension Module`s)** - * An **`Extension Module`** providing a modality (e.g., a TUI implementation) needs to register its handler or main entry point with `utility1`. - * **Mechanism Examples**: Static registration where `utility1`'s build system links modality implementations from known `Extension Module`s. `utility1` might discover modules that implement a `utility1`-defined `ModalityHandler` trait/interface. - -* **B. Information Required for Core Command Registration (Compile-Time via `Extension Module`s)** - * `Extension Module`s make `CommandDefinition` structures (Section 2.3.2) available. - * **Mechanisms**: Procedural macros within `Extension Module`s, static arrays of `CommandDefinition` collected by `utility1`'s build script, or build script code generation that reads module-specific definitions. Routines are typically static function pointers. - -* **C. Information Required for Custom Type Registration (Compile-Time Only via `Extension Module`s)** - * `Extension Module`s make `CustomTypeDefinition` structures available. - * `CustomTypeDefinition` includes `type_name`, static `parser_function`, static `validator_function`, and `help_info`. - * **Mechanisms**: Similar to command registration (macros, static collections, build script generation). Custom types cannot be added at run-time. - -**2. Run-Time Command Registration (Commands Only)** +* **Command in Root Namespace:** + ```sh + utility1 .ping + ``` +* **Command in a Nested Namespace:** + ```sh + utility1 .network.diagnostics.ping + ``` -`utility1` **must** provide a run-time API or mechanism to add new `CommandDefinition`s to its existing unified command registry. +##### B.2. Positional vs. Named Arguments -* **A. Procedural Run-Time API (Example using `noun_verb` convention)** - * `utility1` could expose methods like: - * `fn command_add_runtime(definition: unilang::CommandDefinition, routine: Box Result + Send + Sync>) -> Result<(), RegistrationError>` - * `fn command_remove_runtime(command_name: &str) -> Result<(), UnregistrationError>` (Optional) -* **B. Loading from External Definitions (e.g., YAML/JSON)** - * `utility1` might have a built-in command or mechanism: `utility1 .system.commands.load.file path::/path/to/commands.yaml` - * The loaded `CommandDefinition`s would need their `routine_link` attribute to be resolvable by `utility1`. This could mean the `routine_link` refers to a function symbol within `utility1` itself or one of its compile-time loaded **`Extension Module`s**, or a script function if `utility1` embeds a scripting engine. -* **C. Command Routine Signature (Expected by `unilang` via `utility1`)** - * `fn routine_handler(verified_command: VerifiedCommand, exec_context: ExecutionContext) -> Result` +* **Using a Positional (Default) Argument:** + * Assumes `.log` defines its `message` argument with `is_default_arg: true`. + ```sh + utility1 .log "This is a log message" + ``` +* **Using Named Arguments (Standard):** + ```sh + utility1 .files.copy from::/path/to/source.txt to::/path/to/destination.txt + ``` +* **Using Aliases for Named Arguments:** + * Assumes `from` has an alias `f` and `to` has an alias `t`. + ```sh + utility1 .files.copy f::/path/to/source.txt t::/path/to/destination.txt + ``` -**3. Access to `utility1` Services (via `ExecutionContext`)** -* The `ExecutionContext` is prepared by `utility1` and passed to all routines, whether linked at compile-time or run-time. +##### B.3. Quoting and Escaping -**Example (Conceptual Rust-like Trait for an `ExtensionModule` Interface `utility1` might expect for compile-time contributions):** +* **Value with Spaces:** Quotes are required. + ```sh + utility1 .files.create path::"/home/user/My Documents/report.txt" + ``` +* **Value Containing the Key-Value Separator (`::`):** Quotes are required. + ```sh + utility1 .log message::"DEPRECATED::This function will be removed." + ``` +* **Value Containing Commas for a Non-List Argument:** Quotes are required. + ```sh + utility1 .set.property name::"greeting" value::"Hello, world" + ``` -```rust -// Conceptual - This is what a utility1 integrator might define for its Extension Modules. +##### B.4.

Delete the legacy parser file: `git rm module/move/unilang/src/parsing.rs`. - 2. Delete the legacy command aggregator module: `git rm -r module/move/unilang/src/ca/`. - 3. Update the crate root in `module/move/unilang/src/lib.rs` to remove the module declarations: `pub mod parsing;` and `pub mod ca;`. - * **Increment Verification:** - 1.

This is the core of the refactoring, adapting the semantic logic to the new, correct parser output. - * **Specification Reference:** Implements the "Semantic Analysis" stage of the "Unified Processing Pipeline" defined in `spec.md` (Section 2.2.1). - * **Steps:** - 1. **Update Imports:** In `module/move/unilang/src/semantic.rs`, replace `use crate::parsing::Program;` with `use unilang_instruction_parser::{GenericInstruction, Argument as ParserArgument};`. - 2. **Refactor `SemanticAnalyzer::new`:** Change the constructor's signature from `new(program: &'a Program, ...)` to `new(instructions: &'a [GenericInstruction], ...)`. Update the struct definition to hold `&'a [GenericInstruction]`. - 3. **Refactor `SemanticAnalyzer::analyze`:** - * Rewrite the main loop to iterate over `self.instructions`. - * Inside the loop, resolve the command name by joining the `instruction.command_path_slices` with `.` to form the `String` key for `CommandRegistry` lookup. - 4. **Refactor `bind_arguments` function:** - * Change the function signature to `bind_arguments(instruction: &GenericInstruction, command_def: &CommandDefinition) -> Result, Error>`. - * Implement the new binding logic: - * Iterate through the `command_def.arguments`. - * For each `arg_def`, first check `instruction.named_arguments` for a match by name or alias. - * If not found, check if `arg_def.is_default_arg` is `true` and if there are any available `instruction.positional_arguments`. - * If a value is found (either named or positional), use `unilang::types::parse_value` to convert the raw string into a strongly-typed `unilang::types::Value`. - * If no value is provided, check if `arg_def.optional` is `true` or if a `default_value` exists. - * If a mandatory argument is not found, return a `MISSING_ARGUMENT` error. - * **Increment Verification:** - 1.

This prevents `unilang` from correctly identifying commands when using the parser directly. - * **Action:** Created an `External Crate Change Proposal` for this fix: `module/move/unilang_instruction_parser/task.md`. - * **Workaround:** For the current `unilang` task, tests were modified to manually construct `GenericInstruction` instances, bypassing the faulty `unilang_instruction_parser::Parser` for testing purposes. This allows `unilang`'s semantic analysis and interpreter logic to be verified independently. -* **Compilation Error in `derive_tools`:** Encountered a compilation error in `module/core/derive_tools/src/lib.rs` (`error: expected item after attributes`). This is an issue in an external dependency that blocks `unilang` from compiling. - * **Action:** Created an `External Crate Change Proposal` for this fix: `module/core/derive_tools/task.md`. -* **Current Blocked Status:** The `unilang` architectural unification task is currently blocked by the compilation issue in `derive_tools`. Further progress on `unilang`, including the execution of Increment 4 and the Finalization Increment, requires this external dependency to be fixed. The `task.md` proposals for `unilang_instruction_parser` and `derive_tools` must be addressed before this plan can proceed to completion. \ No newline at end of file diff --git a/module/move/unilang/test_file.txt b/module/move/unilang/test_file.txt deleted file mode 100644 index 30d74d2584..0000000000 --- a/module/move/unilang/test_file.txt +++ /dev/null @@ -1 +0,0 @@ -test \ No newline at end of file diff --git a/module/move/unilang_instruction_parser/Cargo.toml b/module/move/unilang_instruction_parser/Cargo.toml index 8ee71f38ce..5709d5f23e 100644 --- a/module/move/unilang_instruction_parser/Cargo.toml +++ b/module/move/unilang_instruction_parser/Cargo.toml @@ -28,3 +28,6 @@ test_tools = { workspace = true } [lints] workspace = true + + + diff --git a/module/move/unilang_instruction_parser/examples/unilang_instruction_parser_basic.rs b/module/move/unilang_instruction_parser/examples/unilang_instruction_parser_basic.rs index f1d202285a..d8cda1f9c1 100644 --- a/module/move/unilang_instruction_parser/examples/unilang_instruction_parser_basic.rs +++ b/module/move/unilang_instruction_parser/examples/unilang_instruction_parser_basic.rs @@ -3,7 +3,6 @@ //!

Introduction & Core Concepts + +**Design Focus: `Strategic Context`** + +This document is the single source of truth for the `unilang` framework. It defines the language, its components, and the responsibilities of its constituent crates. + +#### 0.1. Scope: A Multi-Crate Framework + +The Unilang specification governs a suite of related crates that work together to provide the full framework functionality. This document is the canonical specification for all of them. The primary crates are: + +* **`unilang`**: The core framework crate that orchestrates parsing, semantic analysis, execution, and modality management. +* **`unilang_instruction_parser`**: A dedicated, low-level crate responsible for the lexical and syntactic analysis of the `unilang` command language (implements Section 2 of this spec). +* **`unilang_meta`**: A companion crate providing procedural macros to simplify compile-time command definition (implements parts of Section 3.4). + +#### 0.2. Goals of `unilang` + +`unilang` provides a unified way to define command-line utility interfaces once, automatically enabling consistent interaction across multiple modalities such as CLI, GUI, TUI, and Web APIs. The core goals are: + +1. **Consistency:** A single way to define commands and their arguments, regardless of how they are presented or invoked. +2. **Discoverability:** Easy ways for users and systems to find available commands and understand their usage. +3. **Flexibility:** Support for various methods of command definition (compile-time, run-time, declarative, procedural). +4. **Extensibility:** Provide structures that enable an integrator to build an extensible system with compile-time `Extension Module`s and run-time command registration. +5. **Efficiency:** Support for efficient parsing and command dispatch. The architecture **must** support near-instantaneous lookup for large sets (100,000+) of statically defined commands by performing maximum work at compile time. +6. **Interoperability:** Standardized representation for commands, enabling integration with other tools or web services, including auto-generation of WEB endpoints. +7. **Robustness:** Clear error handling and validation mechanisms. +8. **Security:** Provide a framework for defining and enforcing secure command execution. + +#### 0.3. System Actors + +* **`Integrator (Developer)`**: The primary human actor who uses the `unilang` framework to build a `utility1` application. They define commands, write routines, and configure the system. +* **`End User`**: A human actor who interacts with the compiled `utility1` application through one of its exposed `Modalities` (e.g., CLI, GUI). +* **`Operating System`**: A system actor that provides the execution environment, including the CLI shell, file system, and environment variables that `utility1` consumes for configuration. +* **`External Service`**: Any external system (e.g., a database, a web API, another process) that a command `Routine` might interact with. + +#### 0.4. Key Terminology (Ubiquitous Language) + +* **`unilang`**: This specification and the core framework crate. +* **`utility1`**: A generic placeholder for the primary application that implements and interprets `unilang`. +* **`Command Lexicon`**: The complete set of all commands available to `utility1` at any given moment. +* **`Command Registry`**: The runtime data structure that implements the `Command Lexicon`. +* **`Command Manifest`**: An external file (e.g., in YAML or JSON format) that declares `CommandDefinition`s for runtime loading. +* **`Command`**: A specific action that can be invoked, identified by its `FullName`. +* **`FullName`**: The complete, unique, dot-separated path identifying a command (e.g., `.files.copy`). +* **`Namespace`**: A logical grouping for commands and other namespaces. +* **`CommandDefinition` / `ArgumentDefinition`**: The canonical metadata for a command or argument. +* **`Routine`**: The executable code (handler function) associated with a command. Its signature is `fn(VerifiedCommand, ExecutionContext) -> Result`. +* **`Modality`**: A specific way of interacting with `utility1` (e.g., CLI, GUI). +* **`parser::GenericInstruction`**: The output of the `unilang_instruction_parser`. +* **`VerifiedCommand`**: A command that has passed semantic analysis and is ready for execution. +* **`ExecutionContext`**: An object providing routines with access to global settings and services. +* **`OutputData` / `ErrorData`**: Standardized structures for returning success or failure results. + +--- + +### 1. Architectural Mandates & Design Principles + +This section outlines the non-negotiable architectural rules and mandatory dependencies for the `unilang` ecosystem. Adherence to these principles is required to ensure consistency, maintainability, and correctness across the framework. + +#### 1.1. Parser Implementation (`unilang_instruction_parser`) + +* **Mandate:** The `unilang_instruction_parser` crate **must not** implement low-level string tokenization (splitting) logic from scratch. It **must** use the `strs_tools` crate as its core tokenization engine. +* **Rationale:** This enforces a clean separation of concerns. `strs_tools` is a dedicated, specialized tool for string manipulation. By relying on it, `unilang_instruction_parser` can focus on its primary responsibility: syntactic analysis of the token stream, not the raw tokenization itself. + +##### Overview of `strs_tools` + +`strs_tools` is a utility library for advanced string splitting and tokenization. Its core philosophy is to provide a highly configurable, non-allocating iterator over a string, giving the consumer fine-grained control over how the string is divided. + +* **Key Principle:** The library intentionally does **not** interpret escape sequences (e.g., `\"`). It provides raw string slices, leaving the responsibility of unescaping to the consumer (`unilang_instruction_parser`). +* **Usage Flow:** The typical workflow involves using a fluent builder pattern: + 1. Call `strs_tools::string::split::split()` to get a builder (`SplitOptionsFormer`). + 2. Configure it with methods like `.delimeter()`, `.quoting(true)`, etc. + 3. Call `.perform()` to get a `SplitIterator`. + 4. Iterate over the `Split` items, which contain the string slice and metadata about the token. + +* **Recommended Components:** + * **`strs_tools::string::split::split()`**: The main entry point function that returns the builder. + * **`SplitOptionsFormer`**: The builder for setting options. Key methods include: + * `.delimeter( &[" ", "::", ";;"] )`: To define what separates tokens. + * `.quoting( true )`: To make the tokenizer treat quoted sections as single tokens. + * `.preserving_empty( false )`: To ignore empty segments resulting from consecutive delimiters. + * **`SplitIterator`**: The iterator produced by the builder. + * **`Split`**: The struct yielded by the iterator, containing the `string` slice, its `typ` (`Delimiter` or `Delimited`), and its `start`/`end` byte positions in the original source. + +#### 1.2. Macro Implementation (`unilang_meta`) + +* **Mandate:** The `unilang_meta` crate **must** prefer using the `macro_tools` crate as its primary dependency for all procedural macro development. Direct dependencies on `syn`, `quote`, or `proc-macro2` should be avoided. +* **Rationale:** `macro_tools` not only re-exports these three essential crates but also provides a rich set of higher-level abstractions and utilities. Using it simplifies parsing, reduces boilerplate code, improves error handling, and leads to more readable and maintainable procedural macros. + + > ❌ **Bad** (`Cargo.toml` with direct dependencies) + > ```toml + > [dependencies] + > syn = { version = "2.0", features = ["full"] } + > quote = "1.0" + > proc-macro2 = "1.0" + > ``` + + > ✅ **Good** (`Cargo.toml` with `macro_tools`) + > ```toml + > [dependencies] + > macro_tools = "0.57" + > ``` + +##### Recommended `macro_tools` Components + +To effectively implement `unilang_meta`, the following components from `macro_tools` are recommended: + +* **Core Re-exports (`syn`, `quote`, `proc-macro2`):** Use the versions re-exported by `macro_tools` for guaranteed compatibility. +* **Diagnostics (`diag` module):** Essential for providing clear, professional-grade error messages to the `Integrator`. + * **`syn_err!( span, "message" )`**: The primary tool for creating `syn::Error` instances with proper location information. + * **`return_syn_err!(...)`**: A convenient macro to exit a parsing function with an error. +* **Attribute Parsing (`attr` and `attr_prop` modules):** The main task of `unilang_meta` is to parse attributes like `#[unilang::command(...)]`. These modules provide reusable components for this purpose. + * **`AttributeComponent`**: A trait for defining a parsable attribute (e.g., `unilang::command`). + * **`AttributePropertyComponent`**: A trait for defining a property within an attribute (e.g., `name = "..."`). + * **`AttributePropertySyn` / `AttributePropertyBoolean`**: Reusable structs for parsing properties that are `syn` types (like `LitStr`) or booleans. +* **Item & Struct Parsing (`struct_like`, `item_struct` modules):** Needed to analyze the Rust code (struct or function) to which the macro is attached. + * **`StructLike`**: A powerful enum that can represent a `struct`, `enum`, or `unit` struct, simplifying the analysis logic. +* **Generics Handling (`generic_params` module):** If commands can be generic, this module is indispensable. + * **`GenericsRef`**: A wrapper that provides convenient methods for splitting generics into parts needed for `impl` blocks and type definitions. +* **General Utilities:** + * **`punctuated`**: Helpers for working with `syn::punctuated::Punctuated` collections. + * **`ident`**: Utilities for creating and manipulating identifiers, including handling of Rust keywords. + +#### 1.3. Framework Parsing (`unilang`) + +* **Mandate:** The `unilang` core framework **must** delegate all command expression parsing to the `unilang_instruction_parser` crate. It **must not** contain any of its own CLI string parsing logic. +* **Rationale:** This enforces the architectural separation between syntactic analysis (the responsibility of `unilang_instruction_parser`) and semantic analysis (the responsibility of `unilang`). This modularity makes the system easier to test, maintain, and reason about. + +--- + +### 2. Language Syntax & Processing (CLI) + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang_instruction_parser` crate** + +This section defines the public contract for the CLI modality's syntax. The `unilang_instruction_parser` crate is the reference implementation for this section. + +#### 2.1. Unified Processing Pipeline + +The interpretation of a `unilang` CLI string by `utility1` **must** proceed through the following conceptual phases: + +1. **Phase 1: Syntactic Analysis (String to `GenericInstruction`)** + * **Responsibility:** `unilang_instruction_parser` crate. + * **Process:** The parser consumes the input and, based on the `unilang` grammar (Appendix A.2), identifies command paths, positional arguments, named arguments (`key::value`), and operators (`;;`, `?`). + * **Output:** A `Vec`. This phase has no knowledge of command definitions; it is purely syntactic. + +2. **Phase 2: Semantic Analysis (`GenericInstruction` to `VerifiedCommand`)** + * **Responsibility:** `unilang` crate. + * **Process:** Each `GenericInstruction` is validated against the `CommandRegistry`. The command name is resolved, arguments are bound to their definitions, types are checked, and validation rules are applied. + * **Output:** A `Vec`. + +3. **Phase 3: Execution** + * **Responsibility:** `unilang` crate's Interpreter. + * **Process:** The interpreter invokes the `Routine` for each `VerifiedCommand`, passing it the validated arguments and execution context. + * **Output:** A `Result` for each command, which is then handled by the active `Modality`. + +#### 2.2. Naming Conventions + +To ensure consistency across all `unilang`-based utilities, the following naming conventions **must** be followed: + +* **Command & Namespace Segments:** Must consist of lowercase alphanumeric characters (`a-z`, `0-9`) and underscores (`_`). Dots (`.`) are used exclusively as separators. Example: `.system.info`, `.file_utils.read_all`. +* **Argument Names & Aliases:** Must consist of lowercase alphanumeric characters and may use `kebab-case` for readability. Example: `input-file`, `force`, `user-name`. + +#### 2.3. Command Expression + +A `command_expression` can be one of the following: +* **Full Invocation:** `[namespace_path.]command_name [argument_value...] [named_argument...]` +* **Help Request:** `[namespace_path.][command_name] ?` or `[namespace_path.]?` + +#### 2.4. Parsing Rules and Precedence + +To eliminate ambiguity, the parser **must** adhere to the following rules in order. + +* **Rule 0: Whitespace Separation** + * Whitespace characters (spaces, tabs) serve only to separate tokens. Multiple consecutive whitespace characters are treated as a single separator. Whitespace is not part of a token's value unless it is inside a quoted string. + +* **Rule 1: Command Path Identification** + * The **Command Path** is the initial sequence of tokens that identifies the command to be executed. + * A command path consists of one or more **segments**. + * Segments **must** be separated by a dot (`.`). Whitespace around the dot is ignored. + * A segment **must** be a valid identifier according to the `Naming Conventions` (Section 2.2). + * The command path is the longest possible sequence of dot-separated identifiers at the beginning of an expression. + +* **Rule 2: End of Command Path & Transition to Arguments** + * The command path definitively ends, and argument parsing begins, upon encountering the **first token** that is not a valid, dot-separated identifier segment. + * This transition is triggered by: + * A named argument separator (`::`). + * A quoted string (`"..."` or `'...'`). + * The help operator (`?`). + * Any other token that does not conform to the identifier naming convention. + * **Example:** In `utility1 .files.copy --force`, the command path is `.files.copy`. The token `--force` is not a valid segment, so it becomes the first positional argument. + +* **Rule 3: Dot (`.`) Operator Rules** + * **Leading Dot:** A single leading dot at the beginning of a command path (e.g., `.files.copy`) is permitted and has no semantic meaning. It is consumed by the parser and does not form part of the command path's segments. + * **Trailing Dot:** A trailing dot after the final command segment (e.g., `.files.copy.`) is a **syntax error**. + +* **Rule 4: Help Operator (`?`)** + * The `?` operator marks the entire instruction for help generation. + * It **must** be the final token in a command expression. + * It **may** be preceded by arguments. If it is, this implies a request for contextual help. The `unilang` framework (not the parser) is responsible for interpreting this context. + * **Valid:** `.files.copy ?` + * **Valid:** `.files.copy from::/src ?` + * **Invalid:** `.files.copy ? from::/src` + +* **Rule 5: Argument Types** + * **Positional Arguments:** Any token that follows the command path and is not a named argument is a positional argument. + * **Named Arguments:** Any pair of tokens matching the `name::value` syntax is a named argument. The `value` can be a single token or a quoted string. + +--- + +### 3. Core Definitions + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate** + +This section defines the core data structures that represent commands, arguments, and namespaces. These structures form the primary API surface for an `Integrator`. + +#### 3.1. `NamespaceDefinition` Anatomy + +A namespace is a first-class entity to improve discoverability and help generation. + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The unique, dot-separated `FullName` of the namespace (e.g., `.files`, `.system.internal`). | +| `hint` | `String` | No | A human-readable explanation of the namespace's purpose. | + +#### 3.2. `CommandDefinition` Anatomy + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The final segment of the command's name (e.g., `copy`). The full path is derived from its registered namespace. | +| `namespace` | `String` | Yes | The `FullName` of the parent namespace this command belongs to (e.g., `.files`). | +| `hint` | `String` | No | A human-readable explanation of the command's purpose. | +| `arguments` | `Vec` | No | A list of arguments the command accepts. | +| `routine` | `Routine` | Yes (for static) | A direct reference to the executable code (e.g., a function pointer). | +| `routine_link` | `String` | No | For commands loaded from a `Command Manifest`, this is a string that links to a pre-compiled, registered routine. | +| `permissions` | `Vec` | No | A list of permission identifiers required for execution. | +| `status` | `Enum` | No (Default: `Stable`) | Lifecycle state: `Experimental`, `Stable`, `Deprecated`. | +| `deprecation_message` | `String` | No | If `status` is `Deprecated`, explains the reason and suggests alternatives. | +| `http_method_hint`| `String` | No | A suggested HTTP method (`GET`, `POST`, etc.) for the Web API modality. | +| `idempotent` | `bool` | No (Default: `false`) | If `true`, the command can be safely executed multiple times. | +| `examples` | `Vec` | No | Illustrative usage examples for help text. | +| `version` | `String` | No | The SemVer version of the individual command (e.g., "1.0.2"). | +| `tags` | `Vec` | No | Keywords for grouping or filtering commands (e.g., "filesystem", "networking"). | + +#### 3.3. `ArgumentDefinition` Anatomy + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The unique (within the command), case-sensitive identifier (e.g., `src`). | +| `hint` | `String` | No | A human-readable description of the argument's purpose. | +| `kind` | `Kind` | Yes | The data type of the argument's value. | +| `optional` | `bool` | No (Default: `false`) | If `true`, the argument may be omitted. | +| `default_value` | `Option` | No | A string representation of the value to use if an optional argument is not provided. It will be parsed on-demand. | +| `is_default_arg`| `bool` | No (Default: `false`) | If `true`, its value can be provided positionally in the CLI. | +| `multiple` | `bool` | No (Default: `false`) | If `true`, the argument can be specified multiple times. | +| `sensitive` | `bool` | No (Default: `false`) | If `true`, the value must be protected (masked in UIs, redacted in logs). | +| `validation_rules`| `Vec` | No | Custom validation logic (e.g., `"min:0"`, `"regex:^.+$"`). | +| `aliases` | `Vec` | No | A list of alternative short names (e.g., `s` for `source`). | +| `tags` | `Vec` | No | Keywords for UI grouping (e.g., "Basic", "Advanced"). | +| `interactive` | `bool` | No (Default: `false`) | If `true`, modalities may prompt for input if the value is missing. | + +#### 3.4. Methods of Command Specification + +The methods for defining commands. The "Compile-Time Declarative" method is primarily implemented by the `unilang_meta` crate. + +1. **Compile-Time Declarative (via `unilang_meta`):** Using procedural macros on Rust functions or structs to generate `CommandDefinition`s at compile time. +2. **Run-Time Procedural:** Using a builder API within `utility1` to construct and register commands dynamically. +3. **External Definition:** Loading `CommandDefinition`s from external files (e.g., YAML, JSON) at compile-time or run-time. + +#### 3.5. The Command Registry + +**Design Focus: `Internal Design`** +**Primary Implementor: `unilang` crate** + +The `CommandRegistry` is the runtime data structure that stores the entire `Command Lexicon`. To meet the high-performance requirement for static commands while allowing for dynamic extension, it **must** be implemented using a **Hybrid Model**. + +* **Static Registry:** + * **Implementation:** A **Perfect Hash Function (PHF)** data structure. + * **Content:** Contains all commands, namespaces, and routines that are known at compile-time. + * **Generation:** The PHF **must** be generated by `utility1`'s build process (e.g., in `build.rs`) from all compile-time command definitions. This ensures that the cost of building the lookup table is paid during compilation, not at application startup. +* **Dynamic Registry:** + * **Implementation:** A standard `HashMap`. + * **Content:** Contains commands and namespaces that are added at runtime (e.g., from a `Command Manifest`). +* **Lookup Precedence:** When resolving a command `FullName`, the `CommandRegistry` **must** first query the static PHF. If the command is not found, it must then query the dynamic `HashMap`. + +--- + +### 4. Global Arguments & Configuration + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate** + +This section defines how an `Integrator` configures `utility1` and how an `End User` can override that configuration. + +#### 4.1. `GlobalArgumentDefinition` Anatomy + +The `Integrator` **must** define their global arguments using this structure, which can then be registered with `utility1`. + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The unique name of the global argument (e.g., `output-format`). | +| `hint` | `String` | No | A human-readable description. | +| `kind` | `Kind` | Yes | The data type of the argument's value. | +| `env_var` | `String` | No | The name of an environment variable that can set this value. | + +#### 4.2. Configuration Precedence + +Configuration values **must** be resolved in the following order of precedence (last one wins): +1. Default built-in values. +2. System-wide configuration file (e.g., `/etc/utility1/config.toml`). +3. User-specific configuration file (e.g., `~/.config/utility1/config.toml`). +4. Project-specific configuration file (e.g., `./.utility1.toml`). +5. Environment variables (as defined in `GlobalArgumentDefinition.env_var`). +6. CLI Global Arguments provided at invocation. + +--- + +### 5. Architectural Diagrams + +**Design Focus: `Strategic Context`** + +These diagrams provide a high-level, visual overview of the system's architecture and flow. + +#### 5.1.

Interaction Modalities + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate (provides the framework)** + +`unilang` definitions are designed to drive various interaction modalities. + +* **6.1. CLI (Command Line Interface):** The primary modality, defined in Section 2. +* **6.2. TUI (Textual User Interface):** An interactive terminal interface built from command definitions. +* **6.3. GUI (Graphical User Interface):** A graphical interface with forms and widgets generated from command definitions. +* **6.4. WEB Endpoints:** + * **Goal:** Automatically generate a web API from `unilang` command specifications. + * **Mapping:** A command `.namespace.command` maps to an HTTP path like `/api/v1/namespace/command`. + * **Serialization:** Arguments are passed as URL query parameters (`GET`) or a JSON body (`POST`/`PUT`). `OutputData` and `ErrorData` are returned as JSON. + * **Discoverability:** An endpoint (e.g., `/openapi.json`) **must** be available to generate an OpenAPI v3+ specification. The content of this specification is derived directly from the `CommandDefinition`, `ArgumentDefinition`, and `NamespaceDefinition` metadata. + +--- + +### 7. Cross-Cutting Concerns + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate** + +This section defines framework-wide contracts for handling common concerns like errors and security. + +#### 7.1. Error Handling (`ErrorData`) + +Routines that fail **must** return an `ErrorData` object. The `code` field should use a standard identifier where possible. + +* **Standard Codes:** `UNILANG_COMMAND_NOT_FOUND`, `UNILANG_ARGUMENT_INVALID`, `UNILANG_ARGUMENT_MISSING`, `UNILANG_TYPE_MISMATCH`, `UNILANG_VALIDATION_RULE_FAILED`, `UNILANG_PERMISSION_DENIED`, `UNILANG_EXECUTION_ERROR`, `UNILANG_IO_ERROR`, `UNILANG_INTERNAL_ERROR`. +* **New Code for External Failures:** `UNILANG_EXTERNAL_DEPENDENCY_ERROR` - To be used when a routine fails due to an error from an external service (e.g., network timeout, API error response). + +```json +{ + "code": "ErrorCodeIdentifier", + "message": "Human-readable error message.", + "details": { + "argument_name": "src", + "location_in_input": { "source_type": "single_string", "start_offset": 15, "end_offset": 20 } + }, + "origin_command": ".files.copy" +} +``` + +#### 7.2. Standard Output (`OutputData`) + +Successful routines **must** return an `OutputData` object. + +```json +{ + "payload": "Any", + "metadata": { "count": 10, "warnings": [] }, + "output_type_hint": "application/json" +} +``` + +#### 7.3. Security + +* **Permissions:** The `permissions` field on a `CommandDefinition` declares the rights needed for execution. The `utility1` `Interpreter` is responsible for checking these. +* **Sensitive Data:** Arguments marked `sensitive: true` **must** be masked in UIs and redacted from logs. + +#### 7.4. Extensibility Model + +* **Compile-Time `Extension Module`s:** Rust crates that can provide a suite of components to `utility1`. An extension module **should** include a manifest file (e.g., `unilang-module.toml`) to declare the components it provides. These components are compiled into the **Static Registry (PHF)**. +* **Run-Time `Command Manifest`s:** `utility1` **must** provide a mechanism to load `CommandDefinition`s from external `Command Manifest` files (e.g., YAML or JSON) at runtime. These commands are registered into the **Dynamic Registry (HashMap)**. The `routine_link` field in their definitions is used to associate them with pre-compiled functions. + +--- + +### 8. Project Management + +**Design Focus: `Strategic Context`** + +This section contains meta-information about the project itself. + +#### 8.1. Success Metrics + +* **Performance:** For a `utility1` application with 100,000 statically compiled commands, the p99 latency for resolving a command `FullName` in the `CommandRegistry` **must** be less than 1 millisecond on commodity hardware. +* **Adoption:** The framework is considered successful if it is used to build at least three distinct `utility1` applications with different modalities. + +#### 8.2. Out of Scope + +The `unilang` framework is responsible for the command interface, not the business logic itself. The following are explicitly out of scope: + +* **Transactional Guarantees:** The framework does not provide built-in transactional logic for command sequences. If a command in a `;;` sequence fails, the framework will not automatically roll back the effects of previous commands. +* **Inter-Command State Management:** The framework does not provide a mechanism for one command to pass complex state to the next, other than through external means (e.g., environment variables, files) managed by the `Integrator`. +* **Business Logic Implementation:** The framework provides the `Routine` execution shell, but the logic inside the routine is entirely the `Integrator`'s responsibility. + +#### 8.3. Open Questions + +This section tracks critical design decisions that are not yet finalized. + +1. **Runtime Routine Linking:** What is the precise mechanism for resolving a `routine_link` string from a `Command Manifest` to a callable function pointer at runtime? Options include a name-based registry populated at startup or dynamic library loading (e.g., via `libloading`). This needs to be defined. +2. **Custom Type Registration:** What is the API and process for an `Integrator` to define a new custom `Kind` and register its associated parsing and validation logic with the framework? + +--- + +### 9. Interpreter / Execution Engine + +**Design Focus: `Internal Design`** +**Primary Implementor: `unilang` crate** + +The Interpreter is the internal `unilang` component responsible for orchestrating command execution. Its existence and function are critical, but its specific implementation details are not part of the public API. + +1. **Routine Invocation:** For each `VerifiedCommand`, the Interpreter retrieves the linked `Routine` from the `CommandRegistry`. +2. **Context Preparation:** It prepares and passes the `VerifiedCommand` object and the `ExecutionContext` object to the `Routine`. +3. **Result Handling:** It receives the `Result` from the `Routine` and passes it to the active `Modality` for presentation. +4. **Sequential Execution:** It executes commands from a `;;` sequence in order, respecting the `on_error` global argument policy. + +--- + +### 10. Crate-Specific Responsibilities + +**Design Focus: `Strategic Context`** + +This section clarifies the role of each crate in implementing this specification. + +#### 10.1. `unilang` (Core Framework) + +* **Role:** The central orchestrator. +* **Responsibilities:** + * **Mandate:** Must use `unilang_instruction_parser` for all syntactic analysis. + * Implements the **Hybrid `CommandRegistry`** (PHF for static, HashMap for dynamic). + * Provides the build-time logic for generating the PHF from compile-time definitions. + * Implements the `SemanticAnalyzer` (Phase 2) and `Interpreter` (Phase 3). + * Defines all core data structures (`CommandDefinition`, `ArgumentDefinition`, etc.). + * Implements the Configuration Management system. + +#### 10.2. `unilang_instruction_parser` (Parser) + +* **Role:** The dedicated lexical and syntactic analyzer. +* **Responsibilities:** + * **Mandate:** Must use the `strs_tools` crate for tokenization. + * Provides the reference implementation for **Section 2: Language Syntax & Processing**. + * Parses a raw string or slice of strings into a `Vec`. + * **It has no knowledge of command definitions, types, or semantics.** + +#### 10.3. `unilang_meta` (Macros) + +* **Role:** A developer-experience enhancement for compile-time definitions. +* **Responsibilities:** + * **Mandate:** Must use the `macro_tools` crate for procedural macro implementation. + * Provides procedural macros (e.g., `#[unilang::command]`) that generate `CommandDefinition` structures. + * These generated definitions are the primary input for the **PHF generation** step in `utility1`'s build process. + +--- + +### 11.

The parser remains in the `ParsingPath` state until a non-identifier/non-dot token is encountered, at which point it transitions to the `ParsingArguments` state and does not transition back. + +### Finalized Internal Design Decisions +*A space for the developer to document key implementation choices for the system's internal design, especially where they differ from the initial recommendations in `specification.md`.* + +- **Decision 1: PHF Crate Selection:** After evaluation, the `phf` crate (version `X.Y.Z`) was chosen for the static registry implementation due to its robust build-time code generation and minimal runtime overhead. +- **Decision 2: Runtime Routine Linking:** The `routine_link` mechanism will be implemented using a `HashMap`. `utility1` integrators will be responsible for registering their linkable functions into this map at startup.

This prevents `unilang` from correctly identifying commands. - -### Problem Statement / Justification -* When `unilang_instruction_parser::Parser::parse_single_str` or `parse_slice` is used with a command string like `.test.command arg1 arg2`, the parser incorrectly populates `GenericInstruction.positional_arguments` with `".test.command"` and `command_path_slices` remains empty. -* This leads to `unilang::semantic::SemanticAnalyzer` failing to find the command, as it expects the command name to be in `command_path_slices`. -* This bug fundamentally breaks the integration of `unilang_instruction_parser` with `unilang` and prevents the `unilang` architectural unification task from proceeding. - -### Proposed Solution / Specific Changes -* **Modify `unilang_instruction_parser::Parser`'s parsing logic:** - * The parser needs to correctly identify the first segment of the input as the command name (or command path slices if it contains dots) and populate `GenericInstruction.command_path_slices` accordingly. - * Subsequent segments should then be treated as arguments (named or positional). -* **Expected API Changes:** No public API changes are expected for `Parser::parse_single_str` or `parse_slice`, but their internal behavior must be corrected. - -### Expected Behavior & Usage Examples (from Requester's Perspective) -* Given the input string `".test.command arg1 arg2"`, `parser.parse_single_str(".test.command arg1 arg2")` should produce a `GenericInstruction` similar to: - ```rust - GenericInstruction { - command_path_slices: vec!["test", "command"], // Or ["test_command"] if it's a single segment - named_arguments: HashMap::new(), - positional_arguments: vec![ - Argument { value: "arg1", ... }, - Argument { value: "arg2", ... }, - ], - // ... other fields - } - ``` -* The `unilang::semantic::SemanticAnalyzer` should then be able to successfully resolve the command. - -### Acceptance Criteria (for this proposed change) -* `unilang_instruction_parser`'s tests related to command parsing (if any exist) should pass after the fix. -* After this fix is applied to `unilang_instruction_parser`, the `unilang` tests (specifically `test_path_argument_type` and others that currently fail with `COMMAND_NOT_FOUND`) should pass without requiring manual construction of `GenericInstruction` in `unilang`. - -### Potential Impact & Considerations -* **Breaking Changes:** No breaking changes to the public API are anticipated, only a correction of existing behavior. -* **Dependencies:** No new dependencies. -* **Performance:** The fix should not negatively impact parsing performance. -* **Testing:** New unit tests should be added to `unilang_instruction_parser` to specifically cover the correct parsing of command names and arguments. - -### Notes & Open Questions -* The current `unilang` task will proceed by temporarily working around this parser bug by manually constructing `GenericInstruction` for its tests. \ No newline at end of file diff --git a/module/move/unilang_instruction_parser/task/.-task_plan.md b/module/move/unilang_instruction_parser/task/.-task_plan.md deleted file mode 100644 index 47ebaf2561..0000000000 --- a/module/move/unilang_instruction_parser/task/.-task_plan.md +++ /dev/null @@ -1,120 +0,0 @@ -# Task Plan: Investigate `strs_tools` API (Blocking Issue) - -### Goal -* To conduct a deeper investigation into the `strs_tools` crate's `SplitOptionsFormer` API to find a definitive, idiomatic solution for passing dynamic delimiters (from `Vec`) without encountering persistent lifetime (`E0716: temporary value dropped while borrowed`) and ownership (`E0308: mismatched types` due to `&mut Self` return) errors.

Verification will be manual review of findings and proposed solution/alternative.) - -### Increments -##### Increment 1: Deep dive into `strs_tools` API and propose solution or alternative -* **Goal:** Find a definitive solution for the `strs_tools` API interaction or propose a justified alternative. -* **Specification Reference:** N/A -* **Steps:** - * Step 1: **(Completed)** Re-read `module/core/strs_tools/src/string/split.rs` and `module/core/strs_tools/src/string/parse_request.rs` to thoroughly understand the `SplitOptionsFormer` and `OpType` definitions, focusing on how lifetimes are handled for delimiters. - * Step 2: **(Completed)** Investigated the `new` method of `SplitOptionsFormer` and `delimeter` method. Confirmed they expect `&'a str` or `Vec<&'a str>`, and `SplitOptionsFormer` stores these references. The `E0716` error is due to `Vec<&str>` being a temporary. The `E0308` error is due to `SplitOptionsFormer` methods returning `&mut Self`, making it impossible to return by value without `Copy` trait. - * Step 3: **(Completed)** Determined that `strs_tools`'s API for dynamic delimiters with `Vec` is fundamentally problematic due to its borrowing nature and the lack of a clear way to extend the lifetime of `Vec<&str>` without complex ownership management or `static` data. - * Step 4: **(Completed)** Researched alternative Rust string splitting libraries. The `regex` crate is a suitable alternative that can handle dynamic delimiters and quoting. - * Step 5: **(Completed)** Documented all findings, including the `strs_tools` API behavior, the proposed alternative library (`regex`), and the rationale. See "Investigation Findings" and "Proposed Solution" sections below. - * Step 6: Perform Increment Verification. -* **Investigation Findings:** - 1. **`strs_tools` API Design:** The `strs_tools::string::split::SplitOptionsFormer` is designed to borrow string slices (`&'a str`) for its delimiters. Its `new` and `delimeter` methods take `D: Into>`, meaning they expect `&'a str` or `Vec<&'a str>`. The `SplitOptionsFormer` then stores these `&'a str` references. - 2. **Root Cause of Errors:** - * `E0716: temporary value dropped while borrowed`: This occurs because when `Vec<&str>` is created from `Vec` (e.g., `self.options.main_delimiters.iter().map(|s| s.as_str()).collect()`) and passed directly to `SplitOptionsFormer::new`, this `Vec<&str>` is a temporary local variable. It is dropped at the end of the statement, but `SplitOptionsFormer` holds references to its contents, leading to dangling pointers. - * `E0308: mismatched types` (for `former` return): This occurs because `SplitOptionsFormer`'s builder methods (like `src`, `quoting`) return `&mut Self` instead of `Self`. This means the `former` variable remains a mutable reference (`&mut SplitOptionsFormer`), and it cannot be returned by value (`SplitOptionsFormer`) because `SplitOptionsFormer` does not implement the `Copy` trait. This makes the builder pattern difficult to use idiomatically for returning the built object. - 3. **Conclusion on `strs_tools`:** Due to these fundamental design choices (borrowing delimiters and `&mut Self` builder returns), `strs_tools` is not suitable for dynamic delimiters from `Vec` without introducing complex lifetime management (e.g., making `Vec<&str>` a field of `Parser` or `UnilangParserOptions` and managing its lifetime, which is overly complex for this use case) or relying on `static` data (which is not applicable for dynamic delimiters). - -* **Proposed Solution: Switch to `regex` crate for string splitting.** - The `regex` crate provides a robust and idiomatic way to split strings using regular expressions, which can be dynamically constructed from a `Vec` of delimiters. It avoids the lifetime complexities of `strs_tools` because the compiled `Regex` object owns its pattern. - - **Steps for Implementation (in a future task):** - 1. Add `regex` as a dependency to `unilang_instruction_parser`'s `Cargo.toml`. - 2. Remove `strs_tools` as a dependency. - 3. In `src/parser_engine.rs`, modify the `tokenize_input` function: - * Construct a regex pattern from `self.options.main_delimiters` (e.g., `delimiters.join("|")`). - * Compile the regex: `let re = Regex::new(&delimiter_pattern).unwrap();` (error handling for regex compilation would be needed). - * Use `re.split(input)` to get an iterator of string slices. - * Re-implement the logic to handle quoted strings. Since `regex`'s basic `split` doesn't handle quotes, the `pre_tokenize_with_quotes` function (or a similar mechanism) would need to be re-introduced and adapted to work with `regex`'s output, or a more advanced regex pattern that captures quoted strings would be needed. - * Classify the resulting segments into `RichItem`s with appropriate `UnilangTokenKind`s. - 4. Update `src/config.rs` and `src/item_adapter.rs` to remove any `strs_tools`-specific logic. - - **Justification for `regex`:** - * **Lifetime Safety:** `regex` handles pattern ownership internally, eliminating the `E0716` and `E0308` lifetime issues encountered with `strs_tools`. - * **Flexibility:** Regular expressions offer powerful and flexible pattern matching for delimiters, including complex multi-character delimiters and character classes. - * **Performance:** `regex` is highly optimized for performance. - * **Idiomatic:** Using `regex` for complex splitting is a common and well-understood pattern in Rust. - -* **Increment Verification:** - * Step 1: **(Completed)** The proposed solution and documentation are clear, correct, and directly address the task's goal. - * Step 2: **(Completed)** The proposed code snippets are conceptual but demonstrate the pattern that resolves the described compilation errors. - * Step 3: **(Completed)** The justification for `regex` as an alternative is strong and considers the blocking issues. -* **Commit Message:** "feat(unilang_instruction_parser): Investigate strs_tools API blocking issue and propose solution/alternative" - -### Task Requirements -* The solution must definitively resolve the `E0716` and `E0308` errors when using `strs_tools` with dynamic delimiters. -* The proposed solution must be implementable within the `unilang_instruction_parser` crate. -* If an alternative library is proposed, it must be a viable replacement for `strs_tools`'s splitting functionality. - -### Project Requirements -* All code must strictly adhere to the `codestyle` rulebook provided by the user at the start of the task. -* Must use Rust 2021 edition. -* All new APIs must be async. - -### Assumptions -* There is a way to resolve the `strs_tools` API interaction, or a suitable alternative exists. - -### Out of Scope -* Implementing the proposed solution in `unilang_instruction_parser` (this task is only for investigation and proposal). -* Full refactoring of `strs_tools` (unless a minimal, targeted change proposal is explicitly approved). - -### External System Dependencies (Optional) -* None - -### Notes & Insights -* The `strs_tools` API for `SplitOptionsFormer` has proven challenging due to its lifetime requirements and builder pattern. - -### Changelog -* [Initial] Task created to investigate blocking `strs_tools` API issues. -* [Increment 1 | 2025-07-06 06:40 UTC] Deep dived into `strs_tools` API.

Introduction & Core Concepts + +**Design Focus: `Strategic Context`** + +This document is the single source of truth for the `unilang` framework. It defines the language, its components, and the responsibilities of its constituent crates. + +#### 0.1. Scope: A Multi-Crate Framework + +The Unilang specification governs a suite of related crates that work together to provide the full framework functionality. This document is the canonical specification for all of them. The primary crates are: + +* **`unilang`**: The core framework crate that orchestrates parsing, semantic analysis, execution, and modality management. +* **`unilang_instruction_parser`**: A dedicated, low-level crate responsible for the lexical and syntactic analysis of the `unilang` command language (implements Section 2 of this spec). +* **`unilang_meta`**: A companion crate providing procedural macros to simplify compile-time command definition (implements parts of Section 3.4). + +#### 0.2. Goals of `unilang` + +`unilang` provides a unified way to define command-line utility interfaces once, automatically enabling consistent interaction across multiple modalities such as CLI, GUI, TUI, and Web APIs. The core goals are: + +1. **Consistency:** A single way to define commands and their arguments, regardless of how they are presented or invoked. +2. **Discoverability:** Easy ways for users and systems to find available commands and understand their usage. +3. **Flexibility:** Support for various methods of command definition (compile-time, run-time, declarative, procedural). +4. **Extensibility:** Provide structures that enable an integrator to build an extensible system with compile-time `Extension Module`s and run-time command registration. +5. **Efficiency:** Support for efficient parsing and command dispatch. The architecture **must** support near-instantaneous lookup for large sets (100,000+) of statically defined commands by performing maximum work at compile time. +6. **Interoperability:** Standardized representation for commands, enabling integration with other tools or web services, including auto-generation of WEB endpoints. +7. **Robustness:** Clear error handling and validation mechanisms. +8. **Security:** Provide a framework for defining and enforcing secure command execution. + +#### 0.3. System Actors + +* **`Integrator (Developer)`**: The primary human actor who uses the `unilang` framework to build a `utility1` application. They define commands, write routines, and configure the system. +* **`End User`**: A human actor who interacts with the compiled `utility1` application through one of its exposed `Modalities` (e.g., CLI, GUI). +* **`Operating System`**: A system actor that provides the execution environment, including the CLI shell, file system, and environment variables that `utility1` consumes for configuration. +* **`External Service`**: Any external system (e.g., a database, a web API, another process) that a command `Routine` might interact with. + +#### 0.4. Key Terminology (Ubiquitous Language) + +* **`unilang`**: This specification and the core framework crate. +* **`utility1`**: A generic placeholder for the primary application that implements and interprets `unilang`. +* **`Command Lexicon`**: The complete set of all commands available to `utility1` at any given moment. +* **`Command Registry`**: The runtime data structure that implements the `Command Lexicon`. +* **`Command Manifest`**: An external file (e.g., in YAML or JSON format) that declares `CommandDefinition`s for runtime loading. +* **`Command`**: A specific action that can be invoked, identified by its `FullName`. +* **`FullName`**: The complete, unique, dot-separated path identifying a command (e.g., `.files.copy`). +* **`Namespace`**: A logical grouping for commands and other namespaces. +* **`CommandDefinition` / `ArgumentDefinition`**: The canonical metadata for a command or argument. +* **`Routine`**: The executable code (handler function) associated with a command. Its signature is `fn(VerifiedCommand, ExecutionContext) -> Result`. +* **`Modality`**: A specific way of interacting with `utility1` (e.g., CLI, GUI). +* **`parser::GenericInstruction`**: The output of the `unilang_instruction_parser`. +* **`VerifiedCommand`**: A command that has passed semantic analysis and is ready for execution. +* **`ExecutionContext`**: An object providing routines with access to global settings and services. +* **`OutputData` / `ErrorData`**: Standardized structures for returning success or failure results. + +--- + +### 1. Architectural Mandates & Design Principles + +This section outlines the non-negotiable architectural rules and mandatory dependencies for the `unilang` ecosystem. Adherence to these principles is required to ensure consistency, maintainability, and correctness across the framework. + +#### 1.1. Parser Implementation (`unilang_instruction_parser`) + +* **Mandate:** The `unilang_instruction_parser` crate **must not** implement low-level string tokenization (splitting) logic from scratch. It **must** use the `strs_tools` crate as its core tokenization engine. +* **Rationale:** This enforces a clean separation of concerns. `strs_tools` is a dedicated, specialized tool for string manipulation. By relying on it, `unilang_instruction_parser` can focus on its primary responsibility: syntactic analysis of the token stream, not the raw tokenization itself. + +##### Overview of `strs_tools` + +`strs_tools` is a utility library for advanced string splitting and tokenization. Its core philosophy is to provide a highly configurable, non-allocating iterator over a string, giving the consumer fine-grained control over how the string is divided. + +* **Key Principle:** The library intentionally does **not** interpret escape sequences (e.g., `\"`). It provides raw string slices, leaving the responsibility of unescaping to the consumer (`unilang_instruction_parser`). +* **Usage Flow:** The typical workflow involves using a fluent builder pattern: + 1. Call `strs_tools::string::split::split()` to get a builder (`SplitOptionsFormer`). + 2. Configure it with methods like `.delimeter()`, `.quoting(true)`, etc. + 3. Call `.perform()` to get a `SplitIterator`. + 4. Iterate over the `Split` items, which contain the string slice and metadata about the token. + +* **Recommended Components:** + * **`strs_tools::string::split::split()`**: The main entry point function that returns the builder. + * **`SplitOptionsFormer`**: The builder for setting options. Key methods include: + * `.delimeter( &[" ", "::", ";;"] )`: To define what separates tokens. + * `.quoting( true )`: To make the tokenizer treat quoted sections as single tokens. + * `.preserving_empty( false )`: To ignore empty segments resulting from consecutive delimiters. + * **`SplitIterator`**: The iterator produced by the builder. + * **`Split`**: The struct yielded by the iterator, containing the `string` slice, its `typ` (`Delimiter` or `Delimited`), and its `start`/`end` byte positions in the original source. + +#### 1.2. Macro Implementation (`unilang_meta`) + +* **Mandate:** The `unilang_meta` crate **must** prefer using the `macro_tools` crate as its primary dependency for all procedural macro development. Direct dependencies on `syn`, `quote`, or `proc-macro2` should be avoided. +* **Rationale:** `macro_tools` not only re-exports these three essential crates but also provides a rich set of higher-level abstractions and utilities. Using it simplifies parsing, reduces boilerplate code, improves error handling, and leads to more readable and maintainable procedural macros. + + > ❌ **Bad** (`Cargo.toml` with direct dependencies) + > ```toml + > [dependencies] + > syn = { version = "2.0", features = ["full"] } + > quote = "1.0" + > proc-macro2 = "1.0" + > ``` + + > ✅ **Good** (`Cargo.toml` with `macro_tools`) + > ```toml + > [dependencies] + > macro_tools = "0.57" + > ``` + +##### Recommended `macro_tools` Components + +To effectively implement `unilang_meta`, the following components from `macro_tools` are recommended: + +* **Core Re-exports (`syn`, `quote`, `proc-macro2`):** Use the versions re-exported by `macro_tools` for guaranteed compatibility. +* **Diagnostics (`diag` module):** Essential for providing clear, professional-grade error messages to the `Integrator`. + * **`syn_err!( span, "message" )`**: The primary tool for creating `syn::Error` instances with proper location information. + * **`return_syn_err!(...)`**: A convenient macro to exit a parsing function with an error. +* **Attribute Parsing (`attr` and `attr_prop` modules):** The main task of `unilang_meta` is to parse attributes like `#[unilang::command(...)]`. These modules provide reusable components for this purpose. + * **`AttributeComponent`**: A trait for defining a parsable attribute (e.g., `unilang::command`). + * **`AttributePropertyComponent`**: A trait for defining a property within an attribute (e.g., `name = "..."`). + * **`AttributePropertySyn` / `AttributePropertyBoolean`**: Reusable structs for parsing properties that are `syn` types (like `LitStr`) or booleans. +* **Item & Struct Parsing (`struct_like`, `item_struct` modules):** Needed to analyze the Rust code (struct or function) to which the macro is attached. + * **`StructLike`**: A powerful enum that can represent a `struct`, `enum`, or `unit` struct, simplifying the analysis logic. +* **Generics Handling (`generic_params` module):** If commands can be generic, this module is indispensable. + * **`GenericsRef`**: A wrapper that provides convenient methods for splitting generics into parts needed for `impl` blocks and type definitions. +* **General Utilities:** + * **`punctuated`**: Helpers for working with `syn::punctuated::Punctuated` collections. + * **`ident`**: Utilities for creating and manipulating identifiers, including handling of Rust keywords. + +#### 1.3. Framework Parsing (`unilang`) + +* **Mandate:** The `unilang` core framework **must** delegate all command expression parsing to the `unilang_instruction_parser` crate. It **must not** contain any of its own CLI string parsing logic. +* **Rationale:** This enforces the architectural separation between syntactic analysis (the responsibility of `unilang_instruction_parser`) and semantic analysis (the responsibility of `unilang`). This modularity makes the system easier to test, maintain, and reason about. + +--- + +### 2. Language Syntax & Processing (CLI) + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang_instruction_parser` crate** + +This section defines the public contract for the CLI modality's syntax. The `unilang_instruction_parser` crate is the reference implementation for this section. + +#### 2.1. Unified Processing Pipeline + +The interpretation of a `unilang` CLI string by `utility1` **must** proceed through the following conceptual phases: + +1. **Phase 1: Syntactic Analysis (String to `GenericInstruction`)** + * **Responsibility:** `unilang_instruction_parser` crate. + * **Process:** The parser consumes the input and, based on the `unilang` grammar (Appendix A.2), identifies command paths, positional arguments, named arguments (`key::value`), and operators (`;;`, `?`). + * **Output:** A `Vec`. This phase has no knowledge of command definitions; it is purely syntactic. + +2. **Phase 2: Semantic Analysis (`GenericInstruction` to `VerifiedCommand`)** + * **Responsibility:** `unilang` crate. + * **Process:** Each `GenericInstruction` is validated against the `CommandRegistry`. The command name is resolved, arguments are bound to their definitions, types are checked, and validation rules are applied. + * **Output:** A `Vec`. + +3. **Phase 3: Execution** + * **Responsibility:** `unilang` crate's Interpreter. + * **Process:** The interpreter invokes the `Routine` for each `VerifiedCommand`, passing it the validated arguments and execution context. + * **Output:** A `Result` for each command, which is then handled by the active `Modality`. + +#### 2.2. Naming Conventions + +To ensure consistency across all `unilang`-based utilities, the following naming conventions **must** be followed: + +* **Command & Namespace Segments:** Must consist of lowercase alphanumeric characters (`a-z`, `0-9`) and underscores (`_`). Dots (`.`) are used exclusively as separators. Example: `.system.info`, `.file_utils.read_all`. +* **Argument Names & Aliases:** Must consist of lowercase alphanumeric characters and may use `kebab-case` for readability. Example: `input-file`, `force`, `user-name`. + +#### 2.3. Command Expression + +A `command_expression` can be one of the following: +* **Full Invocation:** `[namespace_path.]command_name [argument_value...] [named_argument...]` +* **Help Request:** `[namespace_path.][command_name] ?` or `[namespace_path.]?` + +#### 2.4. Parsing Rules and Precedence + +To eliminate ambiguity, the parser **must** adhere to the following rules in order. + +* **Rule 0: Whitespace Separation** + * Whitespace characters (spaces, tabs) serve only to separate tokens. Multiple consecutive whitespace characters are treated as a single separator. Whitespace is not part of a token's value unless it is inside a quoted string. + +* **Rule 1: Command Path Identification** + * The **Command Path** is the initial sequence of tokens that identifies the command to be executed. + * A command path consists of one or more **segments**. + * Segments **must** be separated by a dot (`.`). Whitespace around the dot is ignored. + * A segment **must** be a valid identifier according to the `Naming Conventions` (Section 2.2). + * The command path is the longest possible sequence of dot-separated identifiers at the beginning of an expression. + +* **Rule 2: End of Command Path & Transition to Arguments** + * The command path definitively ends, and argument parsing begins, upon encountering the **first token** that is not a valid, dot-separated identifier segment. + * This transition is triggered by: + * A named argument separator (`::`). + * A quoted string (`"..."` or `'...'`). + * The help operator (`?`). + * Any other token that does not conform to the identifier naming convention. + * **Example:** In `utility1 .files.copy --force`, the command path is `.files.copy`. The token `--force` is not a valid segment, so it becomes the first positional argument. + +* **Rule 3: Dot (`.`) Operator Rules** + * **Leading Dot:** A single leading dot at the beginning of a command path (e.g., `.files.copy`) is permitted and has no semantic meaning. It is consumed by the parser and does not form part of the command path's segments. + * **Trailing Dot:** A trailing dot after the final command segment (e.g., `.files.copy.`) is a **syntax error**. + +* **Rule 4: Help Operator (`?`)** + * The `?` operator marks the entire instruction for help generation. + * It **must** be the final token in a command expression. + * It **may** be preceded by arguments. If it is, this implies a request for contextual help. The `unilang` framework (not the parser) is responsible for interpreting this context. + * **Valid:** `.files.copy ?` + * **Valid:** `.files.copy from::/src ?` + * **Invalid:** `.files.copy ? from::/src` + +* **Rule 5: Argument Types** + * **Positional Arguments:** Any token that follows the command path and is not a named argument is a positional argument. + * **Named Arguments:** Any pair of tokens matching the `name::value` syntax is a named argument. The `value` can be a single token or a quoted string. + +--- + +### 3. Core Definitions + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate** + +This section defines the core data structures that represent commands, arguments, and namespaces. These structures form the primary API surface for an `Integrator`. + +#### 3.1. `NamespaceDefinition` Anatomy + +A namespace is a first-class entity to improve discoverability and help generation. + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The unique, dot-separated `FullName` of the namespace (e.g., `.files`, `.system.internal`). | +| `hint` | `String` | No | A human-readable explanation of the namespace's purpose. | + +#### 3.2. `CommandDefinition` Anatomy + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The final segment of the command's name (e.g., `copy`). The full path is derived from its registered namespace. | +| `namespace` | `String` | Yes | The `FullName` of the parent namespace this command belongs to (e.g., `.files`). | +| `hint` | `String` | No | A human-readable explanation of the command's purpose. | +| `arguments` | `Vec` | No | A list of arguments the command accepts. | +| `routine` | `Routine` | Yes (for static) | A direct reference to the executable code (e.g., a function pointer). | +| `routine_link` | `String` | No | For commands loaded from a `Command Manifest`, this is a string that links to a pre-compiled, registered routine. | +| `permissions` | `Vec` | No | A list of permission identifiers required for execution. | +| `status` | `Enum` | No (Default: `Stable`) | Lifecycle state: `Experimental`, `Stable`, `Deprecated`. | +| `deprecation_message` | `String` | No | If `status` is `Deprecated`, explains the reason and suggests alternatives. | +| `http_method_hint`| `String` | No | A suggested HTTP method (`GET`, `POST`, etc.) for the Web API modality. | +| `idempotent` | `bool` | No (Default: `false`) | If `true`, the command can be safely executed multiple times. | +| `examples` | `Vec` | No | Illustrative usage examples for help text. | +| `version` | `String` | No | The SemVer version of the individual command (e.g., "1.0.2"). | +| `tags` | `Vec` | No | Keywords for grouping or filtering commands (e.g., "filesystem", "networking"). | + +#### 3.3. `ArgumentDefinition` Anatomy + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The unique (within the command), case-sensitive identifier (e.g., `src`). | +| `hint` | `String` | No | A human-readable description of the argument's purpose. | +| `kind` | `Kind` | Yes | The data type of the argument's value. | +| `optional` | `bool` | No (Default: `false`) | If `true`, the argument may be omitted. | +| `default_value` | `Option` | No | A string representation of the value to use if an optional argument is not provided. It will be parsed on-demand. | +| `is_default_arg`| `bool` | No (Default: `false`) | If `true`, its value can be provided positionally in the CLI. | +| `multiple` | `bool` | No (Default: `false`) | If `true`, the argument can be specified multiple times. | +| `sensitive` | `bool` | No (Default: `false`) | If `true`, the value must be protected (masked in UIs, redacted in logs). | +| `validation_rules`| `Vec` | No | Custom validation logic (e.g., `"min:0"`, `"regex:^.+$"`). | +| `aliases` | `Vec` | No | A list of alternative short names (e.g., `s` for `source`). | +| `tags` | `Vec` | No | Keywords for UI grouping (e.g., "Basic", "Advanced"). | +| `interactive` | `bool` | No (Default: `false`) | If `true`, modalities may prompt for input if the value is missing. | + +#### 3.4. Methods of Command Specification + +The methods for defining commands. The "Compile-Time Declarative" method is primarily implemented by the `unilang_meta` crate. + +1. **Compile-Time Declarative (via `unilang_meta`):** Using procedural macros on Rust functions or structs to generate `CommandDefinition`s at compile time. +2. **Run-Time Procedural:** Using a builder API within `utility1` to construct and register commands dynamically. +3. **External Definition:** Loading `CommandDefinition`s from external files (e.g., YAML, JSON) at compile-time or run-time. + +#### 3.5. The Command Registry + +**Design Focus: `Internal Design`** +**Primary Implementor: `unilang` crate** + +The `CommandRegistry` is the runtime data structure that stores the entire `Command Lexicon`. To meet the high-performance requirement for static commands while allowing for dynamic extension, it **must** be implemented using a **Hybrid Model**. + +* **Static Registry:** + * **Implementation:** A **Perfect Hash Function (PHF)** data structure. + * **Content:** Contains all commands, namespaces, and routines that are known at compile-time. + * **Generation:** The PHF **must** be generated by `utility1`'s build process (e.g., in `build.rs`) from all compile-time command definitions. This ensures that the cost of building the lookup table is paid during compilation, not at application startup. +* **Dynamic Registry:** + * **Implementation:** A standard `HashMap`. + * **Content:** Contains commands and namespaces that are added at runtime (e.g., from a `Command Manifest`). +* **Lookup Precedence:** When resolving a command `FullName`, the `CommandRegistry` **must** first query the static PHF. If the command is not found, it must then query the dynamic `HashMap`. + +--- + +### 4. Global Arguments & Configuration + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate** + +This section defines how an `Integrator` configures `utility1` and how an `End User` can override that configuration. + +#### 4.1. `GlobalArgumentDefinition` Anatomy + +The `Integrator` **must** define their global arguments using this structure, which can then be registered with `utility1`. + +| Field | Type | Mandatory | Description | +| :--- | :--- | :--- | :--- | +| `name` | `String` | Yes | The unique name of the global argument (e.g., `output-format`). | +| `hint` | `String` | No | A human-readable description. | +| `kind` | `Kind` | Yes | The data type of the argument's value. | +| `env_var` | `String` | No | The name of an environment variable that can set this value. | + +#### 4.2. Configuration Precedence + +Configuration values **must** be resolved in the following order of precedence (last one wins): +1. Default built-in values. +2. System-wide configuration file (e.g., `/etc/utility1/config.toml`). +3. User-specific configuration file (e.g., `~/.config/utility1/config.toml`). +4. Project-specific configuration file (e.g., `./.utility1.toml`). +5. Environment variables (as defined in `GlobalArgumentDefinition.env_var`). +6. CLI Global Arguments provided at invocation. + +--- + +### 5. Architectural Diagrams + +**Design Focus: `Strategic Context`** + +These diagrams provide a high-level, visual overview of the system's architecture and flow. + +#### 5.1.

Interaction Modalities + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate (provides the framework)** + +`unilang` definitions are designed to drive various interaction modalities. + +* **6.1. CLI (Command Line Interface):** The primary modality, defined in Section 2. +* **6.2. TUI (Textual User Interface):** An interactive terminal interface built from command definitions. +* **6.3. GUI (Graphical User Interface):** A graphical interface with forms and widgets generated from command definitions. +* **6.4. WEB Endpoints:** + * **Goal:** Automatically generate a web API from `unilang` command specifications. + * **Mapping:** A command `.namespace.command` maps to an HTTP path like `/api/v1/namespace/command`. + * **Serialization:** Arguments are passed as URL query parameters (`GET`) or a JSON body (`POST`/`PUT`). `OutputData` and `ErrorData` are returned as JSON. + * **Discoverability:** An endpoint (e.g., `/openapi.json`) **must** be available to generate an OpenAPI v3+ specification. The content of this specification is derived directly from the `CommandDefinition`, `ArgumentDefinition`, and `NamespaceDefinition` metadata. + +--- + +### 7. Cross-Cutting Concerns + +**Design Focus: `Public Contract`** +**Primary Implementor: `unilang` crate** + +This section defines framework-wide contracts for handling common concerns like errors and security. + +#### 7.1. Error Handling (`ErrorData`) + +Routines that fail **must** return an `ErrorData` object. The `code` field should use a standard identifier where possible. + +* **Standard Codes:** `UNILANG_COMMAND_NOT_FOUND`, `UNILANG_ARGUMENT_INVALID`, `UNILANG_ARGUMENT_MISSING`, `UNILANG_TYPE_MISMATCH`, `UNILANG_VALIDATION_RULE_FAILED`, `UNILANG_PERMISSION_DENIED`, `UNILANG_EXECUTION_ERROR`, `UNILANG_IO_ERROR`, `UNILANG_INTERNAL_ERROR`. +* **New Code for External Failures:** `UNILANG_EXTERNAL_DEPENDENCY_ERROR` - To be used when a routine fails due to an error from an external service (e.g., network timeout, API error response). + +```json +{ + "code": "ErrorCodeIdentifier", + "message": "Human-readable error message.", + "details": { + "argument_name": "src", + "location_in_input": { "source_type": "single_string", "start_offset": 15, "end_offset": 20 } + }, + "origin_command": ".files.copy" +} +``` + +#### 7.2. Standard Output (`OutputData`) + +Successful routines **must** return an `OutputData` object. + +```json +{ + "payload": "Any", + "metadata": { "count": 10, "warnings": [] }, + "output_type_hint": "application/json" +} +``` + +#### 7.3. Security + +* **Permissions:** The `permissions` field on a `CommandDefinition` declares the rights needed for execution. The `utility1` `Interpreter` is responsible for checking these. +* **Sensitive Data:** Arguments marked `sensitive: true` **must** be masked in UIs and redacted from logs. + +#### 7.4. Extensibility Model + +* **Compile-Time `Extension Module`s:** Rust crates that can provide a suite of components to `utility1`. An extension module **should** include a manifest file (e.g., `unilang-module.toml`) to declare the components it provides. These components are compiled into the **Static Registry (PHF)**. +* **Run-Time `Command Manifest`s:** `utility1` **must** provide a mechanism to load `CommandDefinition`s from external `Command Manifest` files (e.g., YAML or JSON) at runtime. These commands are registered into the **Dynamic Registry (HashMap)**. The `routine_link` field in their definitions is used to associate them with pre-compiled functions. + +--- + +### 8. Project Management + +**Design Focus: `Strategic Context`** + +This section contains meta-information about the project itself. + +#### 8.1. Success Metrics + +* **Performance:** For a `utility1` application with 100,000 statically compiled commands, the p99 latency for resolving a command `FullName` in the `CommandRegistry` **must** be less than 1 millisecond on commodity hardware. +* **Adoption:** The framework is considered successful if it is used to build at least three distinct `utility1` applications with different modalities. + +#### 8.2. Out of Scope + +The `unilang` framework is responsible for the command interface, not the business logic itself. The following are explicitly out of scope: + +* **Transactional Guarantees:** The framework does not provide built-in transactional logic for command sequences. If a command in a `;;` sequence fails, the framework will not automatically roll back the effects of previous commands. +* **Inter-Command State Management:** The framework does not provide a mechanism for one command to pass complex state to the next, other than through external means (e.g., environment variables, files) managed by the `Integrator`. +* **Business Logic Implementation:** The framework provides the `Routine` execution shell, but the logic inside the routine is entirely the `Integrator`'s responsibility. + +#### 8.3. Open Questions + +This section tracks critical design decisions that are not yet finalized. + +1. **Runtime Routine Linking:** What is the precise mechanism for resolving a `routine_link` string from a `Command Manifest` to a callable function pointer at runtime? Options include a name-based registry populated at startup or dynamic library loading (e.g., via `libloading`). This needs to be defined. +2. **Custom Type Registration:** What is the API and process for an `Integrator` to define a new custom `Kind` and register its associated parsing and validation logic with the framework? + +--- + +### 9. Interpreter / Execution Engine + +**Design Focus: `Internal Design`** +**Primary Implementor: `unilang` crate** + +The Interpreter is the internal `unilang` component responsible for orchestrating command execution. Its existence and function are critical, but its specific implementation details are not part of the public API. + +1. **Routine Invocation:** For each `VerifiedCommand`, the Interpreter retrieves the linked `Routine` from the `CommandRegistry`. +2. **Context Preparation:** It prepares and passes the `VerifiedCommand` object and the `ExecutionContext` object to the `Routine`. +3. **Result Handling:** It receives the `Result` from the `Routine` and passes it to the active `Modality` for presentation. +4. **Sequential Execution:** It executes commands from a `;;` sequence in order, respecting the `on_error` global argument policy. + +--- + +### 10. Crate-Specific Responsibilities + +**Design Focus: `Strategic Context`** + +This section clarifies the role of each crate in implementing this specification. + +#### 10.1. `unilang` (Core Framework) + +* **Role:** The central orchestrator. +* **Responsibilities:** + * **Mandate:** Must use `unilang_instruction_parser` for all syntactic analysis. + * Implements the **Hybrid `CommandRegistry`** (PHF for static, HashMap for dynamic). + * Provides the build-time logic for generating the PHF from compile-time definitions. + * Implements the `SemanticAnalyzer` (Phase 2) and `Interpreter` (Phase 3). + * Defines all core data structures (`CommandDefinition`, `ArgumentDefinition`, etc.). + * Implements the Configuration Management system. + +#### 10.2. `unilang_instruction_parser` (Parser) + +* **Role:** The dedicated lexical and syntactic analyzer. +* **Responsibilities:** + * **Mandate:** Must use the `strs_tools` crate for tokenization. + * Provides the reference implementation for **Section 2: Language Syntax & Processing**. + * Parses a raw string or slice of strings into a `Vec`. + * **It has no knowledge of command definitions, types, or semantics.** + +#### 10.3. `unilang_meta` (Macros) + +* **Role:** A developer-experience enhancement for compile-time definitions. +* **Responsibilities:** + * **Mandate:** Must use the `macro_tools` crate for procedural macro implementation. + * Provides procedural macros (e.g., `#[unilang::command]`) that generate `CommandDefinition` structures. + * These generated definitions are the primary input for the **PHF generation** step in `utility1`'s build process. + +--- + +### 11.

Modify `unilang_meta/Cargo.toml`: + * Add `unilang = { path = "../unilang" }` to `[dependencies]`. + * Add `trybuild = "1.0"` to `[dev-dependencies]`. + 2. Create `tests/` directory and `tests/trybuild.rs` test harness. + 3. In `src/lib.rs`, define the main proc-macro function `command(attr: TokenStream, item: TokenStream) -> TokenStream`. + 4. Using the `macro_tools` API guide, define a struct `CommandAttributes` to parse `name = "..."`, `namespace = "..."`, and `hint = "..."`. + 5. Implement the parsing logic. For this increment, the macro will only parse inputs and return the original function unmodified. + 6. Create a `trybuild` test case (`tests/ui/01-basic-command-compiles.rs`) to verify the macro can be applied and parses correctly without errors. +* **Increment Verification:** + 1. Execute `timeout 90 cargo test -p unilang_meta` via `execute_command`. The `trybuild` test must pass. +* **Commit Message:** "feat(meta): Initial setup for command macro and basic attribute parsing" + +##### Increment 2: Infer `ArgumentDefinition`s from Function Parameters +* **Goal:** Enhance the macro to inspect the parameters of the annotated function and generate the `quote!` block for a `Vec`. +* **Steps:** + 1. In `src/lib.rs`, iterate over the `inputs` of the parsed `syn::ItemFn`. + 2. For each `syn::FnArg`, extract the parameter name (`pat`) and type (`ty`). + 3. Implement a helper function `fn map_type_to_kind(ty: &syn::Type) -> Result<(proc_macro2::TokenStream, bool), syn::Error>` which returns the `unilang::data::Kind` variant as a `TokenStream` and a boolean indicating if the type was an `Option`. + 4. This function must handle `String`, `i64`, `bool`, `PathBuf`, and `Option`. For `Option`, it should recursively call itself on `T` and return `true` for the optional flag. + 5. Generate the `quote!` block that constructs the `Vec`. + 6. Create a `trybuild` test (`tests/ui/02-argument-inference-compiles.rs`) that annotates a function with various parameter types. The test will use a `const` to hold a stringified version of the generated code, which can be asserted in a `.stdout` file. +* **Increment Verification:** + 1. Execute `timeout 90 cargo test -p unilang_meta` via `execute_command`. The new `trybuild` test must pass. +* **Commit Message:** "feat(meta): Infer ArgumentDefinitions from function parameters" + +##### Increment 3: Generate the Routine Wrapper Function +* **Goal:** Generate the crucial wrapper function that translates from the `unilang` interpreter's call signature to the user's function signature. +* **Steps:** + 1. Use `format_ident!` to create a unique name for the wrapper, e.g., `__unilang_wrapper_{user_function_name}`. + 2. Generate the wrapper function with the signature `fn(command: unilang::semantic::VerifiedCommand, context: unilang::interpreter::ExecutionContext) -> Result`. + 3. Inside the wrapper, generate the argument marshalling logic: + * For each parameter of the `User Function`, generate a `let` binding. + * This binding will get the value from `command.arguments.get("arg_name")`. + * It will then match on the `unilang::types::Value` enum (e.g., `Value::Integer(i)`) to extract the raw Rust type. + * Handle `Option` types by checking if the argument exists in the map. + * If a required argument is missing or has the wrong type, return an `Err(ErrorData { ... })`. + 4. Generate the call to the original `User Function` using the now-bound local variables. + 5. Wrap the return value of the `User Function` in `Ok(OutputData { payload: result.to_string(), ... })`. + 6. Create a `trybuild` test (`tests/ui/03-wrapper-generation-compiles.rs`) to ensure this complex generation results in valid, compilable code. +* **Increment Verification:** + 1. Execute `timeout 90 cargo test -p unilang_meta` via `execute_command`. The new `trybuild` test must pass. +* **Commit Message:** "feat(meta): Generate routine wrapper function for signature translation" + +##### Increment 4: Generate Static `CommandDefinition` +* **Goal:** Generate the final `static CommandDefinition` instance and a unique registration function that ties everything together. +* **Steps:** + 1. Use `format_ident!` to create a unique name for the static definition, e.g., `__UNILANG_DEF_MY_COMMAND`. + 2. Generate the `static` item, populating its fields with the parsed attributes (Increment 1) and the generated `Vec` (Increment 2). + 3. Set the `routine` field to be a function pointer to the **wrapper function** generated in Increment 3. + 4. Generate a public registration function (e.g., `pub fn __unilang_register_my_command() -> &'static CommandDefinition`) that returns a reference to the static definition. + 5. The macro will now output the original user function, the wrapper function, the static definition, and the registration function. + 6. Create a `trybuild` test (`tests/ui/04-generates-full-definition.rs`) that calls the registration function and asserts that the fields of the returned `CommandDefinition` are correct. +* **Increment Verification:** + 1. Execute `timeout 90 cargo test -p unilang_meta` via `execute_command`. The new `trybuild` test must pass. +* **Commit Message:** "feat(meta): Generate static CommandDefinition pointing to wrapper routine" + +##### Increment 5: Finalization and Advanced Features +* **Goal:** Add support for more complex attributes, improve error handling, and finalize the implementation. +* **Steps:** + 1. Extend the attribute parser to handle more `CommandDefinition` fields (`status`, `permissions`, etc.). + 2. Enhance argument inference to allow overrides via an attribute on the function parameter itself, e.g., `#[unilang::arg(hint = "...", multiple = true)] src: String`. + 3. Implement robust error handling using `macro_tools::diag::syn_err!` for invalid usage. + 4. Add `trybuild` tests for all new features and, crucially, add failing test cases (`.rs` files that are expected to produce a specific `.stderr` output) to verify the error messages. + 5. Add documentation to `src/lib.rs` explaining how to use the macro. + 6. Perform the final Crate Conformance Check. +* **Increment Verification:** + 1. Execute `timeout 90 cargo test -p unilang_meta --all-targets`. All tests must pass. + 2. Execute `timeout 90 cargo clippy -p unilang_meta -- -D warnings`. No warnings should be present. +* **Commit Message:** "feat(meta): Add advanced attributes and robust error handling" + +### Changelog +* [Initial] Plan created to implement the `#[unilang::command]` procedural macro with a focus on generating a routine wrapper. \ No newline at end of file diff --git a/module/move/unilang_meta/task/tasks.md b/module/move/unilang_meta/task/tasks.md new file mode 100644 index 0000000000..d4532831c0 --- /dev/null +++ b/module/move/unilang_meta/task/tasks.md @@ -0,0 +1,16 @@ +#### Tasks + +| Task | Status | Priority | Responsible | +|---|---|---|---| +| [`implement_command_macro_task.md`](./implement_command_macro_task.md) | Not Started | High | @user | + +--- + +### Issues Index + +| ID | Name | Status | Priority | +|---|---|---|---| + +--- + +### Issues diff --git a/module/move/wca/Cargo.toml b/module/move/wca/Cargo.toml index eaa9e446bc..153e3c7571 100644 --- a/module/move/wca/Cargo.toml +++ b/module/move/wca/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "wca" -version = "0.25.0" +version = "0.26.0" edition = "2021" authors = [ "Kostiantyn Wandalen ", diff --git a/patch b/patch deleted file mode 100644 index f21a1e0395..0000000000 --- a/patch +++ /dev/null @@ -1,69 +0,0 @@ ---- a/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs -+++ b/module/core/former_meta/src/derive_former/former_enum/struct_non_zero.rs -@@ -753,7 +753,7 @@ - } - // Construct DefinitionTypes generics list for the bound - // FIX: Use iter().cloned() to get owned GenericParams -- let mut def_types_bound_generics_vec : Vec = enum_generics_ty_no_comma.iter().cloned().collect();

Goals & Philosophy + +The primary goal of `strs_tools` is to provide a powerful and flexible set of string manipulation utilities that empower developers to parse complex data with confidence and clarity. + +* **Configurability over Hardcoding:** Employ a fluent builder pattern (Formers). +* **Correctness and Robustness:** Prioritize correct handling of edge cases. +* **Modularity and Pay-as-you-go:** Utilize a feature-gating system. +* **Clarity and Ergonomics:** Provide a clear and discoverable API. + +### 1.2. Architectural Principles + +These are the non-negotiable, crate-wide design laws. + +1. **Consumer Owns Unescaping:** The library **must not** perform any interpretation of escape sequences (e.g., `\"` -> `"`). It yields raw string slices. This is a critical security and correctness principle. +2. **Panic on Invalid Configuration:** `Former` structures **must** panic if consumed with an invalid configuration. This treats configuration errors as developer errors. +3. **Composition of Layers:** Higher-level modules **must** be implemented by composing the public APIs of lower-level modules. +4. **Graceful Handling of Malformed Input:** The library **must not** panic on malformed user input (e.g., unclosed quotes) during iteration. + +### 1.3. API Design & Namespace Philosophy + +The library's public API is exposed through a deliberate, four-tiered namespace structure to provide flexibility for different import styles. + +* **`private` (Internal):** Contains all implementation details. It is not part of the public API. +* **`own`:** Contains the primary, owned types of a module (e.g., `SplitIterator`). This is for developers who want to be explicit and avoid name clashes. + * *Usage Example:* `use strs_tools::string::split::own::SplitIterator;` +* **`exposed`:** Re-exports the `own` namespace under the module's name (e.g., `pub use super::own as split`). This is the intended entry point for qualified path usage. + * *Usage Example:* `strs_tools::string::split::split()` +* **`prelude`:** Contains the most essential types and builder functions intended for convenient glob import. + * *Usage Example:* `use strs_tools::prelude::*; let iter = split()...;` +* **`orphan`:** An internal implementation detail used to structure the re-exports between `exposed` and `own`. It should not be used directly. + +### 1.4. Component Interaction Model + +The `strs_tools` library is designed as a system of composable layers. Higher-level modules delegate their core parsing logic to the `split` tokenizer, ensuring consistent behavior. + +#### Static Structure + +This diagram shows the static relationships between the main components. + +```mermaid +graph TD + subgraph User Facing API + A[parse_request::request_parse] --> B{Request String}; + C[split::split] --> D{Source String}; + E[isolate::isolate_left] --> D; + end + + subgraph Core Logic + A -- delegates to --> C; + A -- also delegates to --> E; + C -- yields --> F[Split Iterator]; + end + + style A fill:#cde4ff,stroke:#333,stroke-width:2px + style C fill:#cde4ff,stroke:#333,stroke-width:2px + style E fill:#cde4ff,stroke:#333,stroke-width:2px +``` + +#### Dynamic Flow (Sequence Diagram) + +This diagram illustrates the sequence of calls for a typical `parse_request` operation, demonstrating the "Composition of Layers" principle in action. + +```mermaid +sequenceDiagram + actor User + participant PR as parse_request + participant S as split + participant I as isolate + + User->>PR: Calls .parse() on "cmd k:v" + activate PR + PR->>S: Calls .perform() on "cmd k:v" with "" delimiter + activate S + S-->>PR: Returns iterator yielding ["cmd k:v"] + deactivate S + PR->>I: Calls .isolate() on "cmd k:v" with ":" delimiter + activate I + I-->>PR: Returns ("cmd", Some(":"), "k:v") + deactivate I + PR->>S: Calls .perform() on "k:v" with ":" delimiter + activate S + S-->>PR: Returns iterator yielding ["k", "v"] + deactivate S + PR-->>User: Returns Request struct { subject: "cmd", map: {"k": "v"} } + deactivate PR +``` + +### 1.5. API Usage & Lifetime Considerations + +This section addresses critical design aspects of the API that affect how it must be used, particularly concerning data ownership and lifetimes. Failure to adhere to these patterns will likely result in compiler errors. + +#### 1.5.1. Handling Dynamic Delimiters (The `E0716` Pitfall) + +A primary design choice of the `split` module is that it **borrows** its delimiters. The `SplitOptionsFormer` holds a lifetime `'a` and expects string slices (`&'a str`) that live at least as long as the `Former` itself. This has a critical implication when working with owned `String` data. + +**Problematic Pattern (will not compile):** +```rust,ignore +// This code will fail with E0716: temporary value dropped while borrowed +let my_delims: Vec = vec!["a".to_string(), "b".to_string()]; +let iter = split() + // This creates a temporary Vec<&str> that is dropped at the end of the line, + // leaving the Former with dangling references. + .delimeter(my_delims.iter().map(|s| s.as_str()).collect::>()) + .src("c a d b e") + .perform(); +``` + +**Correct Pattern:** +The `Vec<&str>` containing the borrowed slices must be bound to a variable with a lifetime that encloses the use of the `Former`. + +```rust +let my_delims: Vec = vec!["a".to_string(), "b".to_string()]; +// 1. Create the vector of slices and bind it to a variable. +let delims_as_slices: Vec<&str> = my_delims.iter().map(|s| s.as_str()).collect(); + +// 2. Pass the bound variable to the Former. `delims_as_slices` now lives +// long enough for the `perform()` call. +let iter = split() + .delimeter(delims_as_slices) + .src("c a d b e") + .perform(); +``` + +#### 1.5.2. The `&mut Self` Builder Pattern + +The `Former` structs in this library use a builder pattern where configuration methods (e.g., `.src()`, `.quoting()`) return a mutable reference (`&mut Self`) rather than an owned value (`Self`). + +* **Implication:** This means a configured `Former` cannot be directly returned from a function, as this would involve moving out of a mutable reference. +* **Rationale:** This design allows a `Former` to be created and then conditionally modified in multiple steps within the same scope before being consumed. + +### 1.6. Non-Functional Requirements (NFRs) + +| ID | Requirement | Description | Verification | +| :--- | :--- | :--- | :--- | +| **NFR-1** | **Performance** | Iteration over a string **must not** involve unnecessary allocations. The `SplitIterator` should be lazy and only perform work when `.next()` is called. | Benchmarks must show that splitting a large string without collecting has a low, constant memory overhead. | +| **NFR-2** | **Memory** | The library must be usable in `no_std` environments (with `alloc`). | The crate must successfully compile and pass all relevant tests with the `no_std` and `use_alloc` features enabled. | +| **NFR-3** | **Modularity** | Feature gates **must** successfully exclude unused modules from compilation. | Compiling with `--no-default-features --features string_split` must not compile the `parse_request` or `indentation` modules. | + +### 1.7. Out of Scope + +To clarify the library's boundaries, the following functionalities are explicitly out of scope: + +* **Character Set Conversion:** The library operates on Rust `&str` slices and assumes the input is valid UTF-8. It does not perform any encoding or decoding. +* **Content Unescaping:** As per the architectural principles, the library does not interpret escape sequences (e.g., `\n`, `\t`, `\"`). This is the responsibility of the consumer. +* **Network or I/O Operations:** This is a pure string manipulation library and will not include any features for reading from files, sockets, or other I/O sources. + +--- + +## Section 2: Component Specifications + +This section provides a detailed specification for each public module. + +### 2.1. Module: `string::split` + +#### Purpose + +The core tokenization engine. It splits a string based on a complex set of rules, including multiple delimiters and quoted sections. + +#### Internal Architecture + +The module uses a two-iterator wrapper pattern. The user-facing `SplitIterator` provides the rich feature set (quoting, stripping) by managing and interpreting the raw output of a more primitive, internal `SplitFastIterator`. + +```mermaid +graph TD + subgraph Public API + A[SplitOptionsFormer] -- .perform() --> B(SplitIterator); + end + subgraph Internal Logic + B -- Wraps & Manages --> C(SplitFastIterator); + C -- Performs basic tokenization --> D{Raw Split Segments}; + B -- Applies quoting/filtering rules to --> D; + B -- Yields --> E[Final Split Struct]; + end + style B fill:#cde4ff,stroke:#333,stroke-width:2px +``` + +#### Core Data Structures & API + +* **`struct Split<'a>`**: Represents a segment with `string`, `typ`, `start`, and `end` fields. +* **`enum SplitType`**: `Delimited` or `Delimiter`. +* **`bitflags! struct SplitFlags`**: `PRESERVING_EMPTY`, `PRESERVING_DELIMITERS`, `PRESERVING_QUOTING`, `STRIPPING`, `QUOTING`. +* **`SplitOptionsFormer<'a>`**: The builder returned by `split()`. Provides methods like `.src()`, `.delimeter()`, `.quoting(bool)`, etc., and is consumed by `.perform()`. + +### 2.2. Module: `string::parse_request` + +#### Purpose + +A higher-level parser for structured commands that have a subject and a map of key-value properties. + +#### Core Data Structures & API + +* **`struct Request<'a>`**: Represents a parsed request with `original`, `subject`, `subjects`, `map`, and `maps` fields. +* **`enum OpType`**: A wrapper for a property value: `Primitive(T)` or `Vector(Vec)`. +* **`ParseOptions<'a>`**: The builder returned by `request_parse()`. Provides methods like `.src()`, `.key_val_delimeter()`, and is consumed by `.parse()`. + +### 2.3. Module: `string::isolate` + +#### Purpose + +A specialized function to split a string into exactly three parts: left content, the first delimiter, and right content. + +#### Core Data Structures & API + +* **`IsolateOptions<'a>`**: A builder returned by `isolate_left()` or `isolate_right()`. +* `.isolate() -> (&'a str, Option<&'a str>, &'a str)`: Consumes the builder and returns the result tuple. + +### 2.4. Module: `string::indentation` + +#### Purpose + +A stateless function to add a prefix and/or postfix to each line of a string. + +#### Core Data Structures & API + +* `indentation(prefix, src, postfix) -> String`: A direct function call. + +### 2.5. Module: `string::number` + +#### Purpose + +A thin wrapper around the `lexical` crate for parsing numbers, managed by the `string_parse_number` feature gate. + +#### Core Data Structures & API + +* Re-exports functions like `parse()` and `parse_partial()` from the `lexical` crate. + +--- + +### Section 3: Verification + +#### 3.1. Conformance Check Procedure + +This procedure verifies that an implementation conforms to this specification. + +| Check ID | Module | Description | Rationale | +| :--- | :--- | :--- | :--- | +| **CHK-SPL-01** | `split` | **Default Behavior:** Correctly splits a simple string. | Ensures the most basic functionality is correct. | +| **CHK-SPL-02** | `split` | **Quoting:** Correctly treats a quoted section as a single token. | Verifies the core logic for handling complex, user-provided content. | +| **CHK-SPL-03** | `split` | **Span Indices:** Correctly reports the start/end byte indices. | Ensures that downstream tools can reliably locate tokens in the original source. | +| **CHK-REQ-01** | `parse_request` | **Composition:** Correctly parses a command with a subject and properties. | Verifies the composition of `split` and `isolate` to build a higher-level parser. | +| **CHK-ISO-01** | `isolate` | **Directional Isolate:** Correctly isolates the first delimiter from the specified direction. | Ensures the lightweight wrapper around `splitn`/`rsplitn` is functioning as expected. | +| **CHK-ARC-01** | Crate-wide | **Unescaping Principle:** Verify that escaped quotes are not unescaped by `split`. | Verifies strict adherence to the 'Consumer Owns Unescaping' architectural principle. | +| **CHK-API-01** | Crate-wide | **Dynamic Delimiter Lifetime:** Verify the documented pattern for using `Vec` as delimiters compiles and works correctly. | To ensure the primary API pitfall is explicitly tested and the documented solution remains valid. | +| **CHK-NFR-03** | Crate-wide | **Modularity Principle:** Verify feature gates correctly exclude code. | Verifies adherence to the 'Modularity' NFR and ensures lean builds are possible. | + +# Specification Addendum + +### Purpose +This document is a companion to the main `specification.md`. It is intended to be completed by the **Developer** during the implementation phase. While the main specification defines the "what" and "why" of the project architecture, this addendum captures the "how" of the final implementation. + +### Instructions for the Developer +As you build the system, please fill out the sections below with the relevant details. This creates a crucial record for future maintenance, debugging, and onboarding. + +--- + +### Implementation Notes +*A space for any key decisions, trade-offs, or discoveries made during development that are not captured elsewhere. For example: "Chose library X over Y because of its superior error handling for our specific use case."* + +- [Note 1] +- [Note 2] + +### Environment Variables +*List all environment variables required to run the application. Include the variable name, a brief description of its purpose, and an example value (use placeholders for secrets).* + +| Variable | Description | Example | +| :--- | :--- | :--- | +| `API_KEY_SERVICE_X` | The API key for connecting to Service X. | `sk_xxxxxxxxxxxx` | +| `DATABASE_URL` | The connection string for the production database. | `postgres://user:pass@host:port/db` | + +### Finalized Library & Tool Versions +*List the critical libraries, frameworks, or tools used and their exact locked versions (e.g., from `package.json` or `requirements.txt`).* + +- `rustc`: `1.78.0` +- `lexical`: `7.0.4` +- `bitflags`: `2.5.0` + +### Deployment Checklist +*A step-by-step guide for deploying the application from scratch. Include steps for setting up the environment, running migrations, and starting the services.* + +1. Clone the repository: `git clone ...` +2. Install dependencies: `cargo build` +3.

Currently, when `strs_tools::split()...form()` is used with a `Vec<&str>` as the delimiter type (e.g., `delimeter(vec!["...", "..."])`), the resulting `split::private::SplitOptions` struct fails to satisfy the `Iterator` trait bounds, leading to compilation errors like `error[E0599]: the method `into_iter` exists for struct ..., but its trait bounds were not satisfied`. This prevents the `unilang_instruction_parser` from compiling and utilizing `strs_tools` as intended. A Minimal Reproducible Example (MRE) demonstrating this issue has been created at `module/move/unilang_instruction_parser/tests/strs_tools_mre.rs`. + +### Proposed Solution / Specific Changes +* **API Changes:** No public API changes are expected for `strs_tools`. The change is internal to ensure existing `Iterator` trait implementations are correctly satisfied for all valid `D` types, specifically `Vec<&str>`. +* **Behavioral Changes:** `strs_tools::split::SplitOptions` should behave as a standard iterator when `Vec<&str>` is used as the delimiter type, allowing direct iteration and collection into `Vec>`. +* **Internal Changes:** The internal implementation of `SplitOptions` or its `Iterator` trait bounds may need adjustment to correctly handle the `Vec<&str>` delimiter type. This might involve ensuring lifetimes are correctly propagated or that `OpType` correctly implements `From>` in all necessary contexts for iteration. + +### Expected Behavior & Usage Examples (from Requester's Perspective) +* The `unilang_instruction_parser` expects to be able to use `strs_tools::split()...form().iter().collect()` or `for s in strs_tools::split()...form()` without compilation errors. +* Example from `unilang_instruction_parser`: + ```rust + use strs_tools::string::split::{ Split, SplitType }; + let input = "test string"; + let delimiters = vec![ " " ]; + let splits : Vec< Split<'_> > = strs_tools::split() + .src( input ) + .delimeter( delimiters ) + .form() + .iter() // This line currently causes the error + .collect(); + // Expected: `splits` contains the correctly parsed `Split` items. + ``` + +### Acceptance Criteria (for this proposed change) +* The `module/move/unilang_instruction_parser/tests/strs_tools_mre.rs` test compiles and passes (or is ignored if the fix makes it unnecessary to run). +* The `unilang_instruction_parser` crate compiles successfully when using `strs_tools::split()...form().iter().collect()` with `Vec<&str>` delimiters. + +### Potential Impact & Considerations +* **Breaking Changes:** No breaking changes are anticipated, as this aims to fix an existing compilation issue and ensure expected `Iterator` behavior. +* **Dependencies:** No new dependencies. +* **Performance:** No significant performance impact is expected. +* **Testing:** The `strs_tools` crate's test suite should be updated to include a test case similar to the provided MRE to prevent regressions. + +### Notes & Open Questions +* The exact cause of the unsatisfied trait bounds for `SplitOptions<'_, Vec<&str>>: Iterator` needs to be investigated within the `strs_tools` crate. \ No newline at end of file diff --git a/temp_strs_tools_fix/tests/debug_hang_split_issue.rs b/temp_strs_tools_fix/tests/debug_hang_split_issue.rs new file mode 100644 index 0000000000..ad8b91eed6 --- /dev/null +++ b/temp_strs_tools_fix/tests/debug_hang_split_issue.rs @@ -0,0 +1,22 @@ +//!
