This unstable feature is not available on stable Rust, blocking compilation for any dependent crates. +* Additionally, `former_meta` generates clippy warnings: `unused import: quote::quote_spanned`, `unreachable expression`, and `unused variable: attr_property`. These warnings prevent clean builds when `-D warnings` is enabled. + +### Proposed Solution / Specific Changes +* **File:** `src/lib.rs` + * **Change:** Remove or conditionally compile `#![ feature( proc_macro_totokens ) ]`.

(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/src/string/split.rs b/module/core/strs_tools/src/string/split.rs index 1eb75926bb..9a6007cd4b 100644 --- a/module/core/strs_tools/src/string/split.rs +++ b/module/core/strs_tools/src/string/split.rs @@ -1,22 +1,43 @@ -/// Private namespace. +//!

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. + +### 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. + +### 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. + +### 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). + +### 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`. + +### 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. + +### 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. diff --git a/module/core/strs_tools/tests/debug_hang_split_issue.rs b/module/core/strs_tools/tests/debug_hang_split_issue.rs new file mode 100644 index 0000000000..ad8b91eed6 --- /dev/null +++ b/module/core/strs_tools/tests/debug_hang_split_issue.rs @@ -0,0 +1,22 @@ +//!

The `analyze_items_to_instructions` function will need to be aware of segment boundaries if it needs to report errors spanning multiple original segments, or the `Parser` will need to pass `seg_idx` to error creation. For now, assume `analyze_items_to_instructions` receives a flat `Vec>` and error locations are based on these items' local spans. The final `ParseError` constructor will need `seg_idx` if the error is tied to an item from a slice. - * A simpler way for `parse_slice`: itemize each segment, then in `analyze_items_to_instructions`, if an error occurs with an `Item`, its original `item.location` (from `strs_tools`) is used along with the `segment_index` (which needs to be tracked alongside items from slices) to form the `SourceLocation::SliceSegment`. - * Pass the combined `Vec>` (potentially with segment origin info) to `analyze_items_to_instructions`. - * Detailed Plan Step 7: Add basic tests for `parse_single_str` and `parse_slice` (empty input, single command name). - * Relevant Behavior Rules: E0, E9, E10. - * Verification Strategy: `cargo test --package unilang_instruction_parser`. - * Commit Message: `feat(unilang_parser): Impl parser config, entry points, and initial input handling` - -* ⚫ **Increment 3: Syntactic Analyzer - Command Structure (Path, Help, Command Separation)** - * Target Crate(s): `unilang_instruction_parser` - * Detailed Plan Step 1: In `parser_engine.rs`, implement `fn analyze_items_to_instructions<'input>(&self, items: Vec>, input_origin: InputOrigin /* enum { SingleStr, Slice(&'input [&'input str]) } */ ) -> Result>, ParseError>`.

Store locations. - * Handle errors for malformed named args (e.g., name without `::` or value). - * Relevant Behavior Rules: E1, E2 (`::`), E3. - * Verification Strategy: `cargo test --package unilang_instruction_parser` for arguments. - * Commit Message: `feat(unilang_parser): Implement named and positional argument parsing` - -### Phase 3: Refinements and Testing - -* ⚫ **Increment 5: Error Reporting and `SourceLocation` Integration** - * Target Crate(s): `unilang_instruction_parser` - * Detailed Plan Step 1: Ensure all paths in `analyze_items_to_instructions` that generate `ParseError` correctly populate `ParseError::location` with a `SourceLocation`. - * If processing items from `parse_single_str`, use `SourceLocation::StrSpan` based on `item.location`. - * If processing items from `parse_slice`, this is where the `segment_index` associated with the failing `item` is crucial to construct `SourceLocation::SliceSegment`. The `analyze_items_to_instructions` might need to receive items as `Vec<(Item<'input>, Option/*seg_idx*/)>` or the `Parser` needs a way to map a global item index back to its original segment if `parse_slice` flattens everything. - * *Decision for Slice Location:* `parse_slice` should probably not flatten items immediately. It could call `analyze_items_to_instructions` per segment, or `analyze_items_to_instructions` needs to be more aware. A simpler start: `parse_slice` itemizes segment by segment. If an itemization error occurs within a segment, its location is already relative. If a syntactic error occurs later with items from a slice, the `Item` itself should carry enough info (or be wrappable) to trace back to its original segment_index and its local location. - * *Revised approach for Slice Location in `analyze_items_to_instructions`*: The `Item` struct from `strs_tools` only has `start/end` byte offsets. When `parse_slice` calls `itemize_all` on each segment, it gets `Item`s whose locations are relative to *that segment*. `parse_slice` must then transform these `Item`s (or wrap them) to include the `segment_index` before passing them to a flattened analysis stage, OR the analysis must happen per-segment and results aggregated. - * **Let's simplify:** `analyze_items_to_instructions` takes `items: Vec>` and `segment_index: Option`. `parse_single_str` calls it with `None`. `parse_slice` calls it for *each segment's items* with `Some(seg_idx)`. This means `analyze_items_to_instructions` might produce partial `GenericInstruction`s if a unilang command spans multiple shell arguments, which then need to be stitched together. This is getting complex. - * **Alternative for `parse_slice`:** Concatenate all string segments from the slice into one temporary owned `String` (with a special, non-printable separator if needed to map locations back accurately, or by tracking original segment lengths). Then parse this single string. This simplifies location tracking to always be `StrSpan` but introduces an allocation and copying. - * **Chosen Path (Compromise):** `parse_slice` will itemize each segment. The `Vec>` passed to `analyze_items_to_instructions` will be flat. Each `Item` needs to be augmented or wrapped to carry its original `segment_idx`. - ```rust - // In unilang_instruction_parser, perhaps in input_adapter.rs or alongside Item - struct RichItem<'a> { - inner: strs_tools::string::parser::Item<'a>, - segment_idx: Option, // None for single_str input - } - ``` - `analyze_items_to_instructions` works on `Vec>`. - * Verification Strategy: Tests for errors in both input modes, checking `ParseError.location`. - * Commit Message: `fix(unilang_parser): Integrate SourceLocation for precise error reporting` - -* ⚫ **Increment 6: Comprehensive Test Suite (Test Matrix)** - * (As per previous plan: cover input types, command structures, arg types, value types, delimiters, operators, quoting, errors, edge cases). - * Verification Strategy: `cargo test --package unilang_instruction_parser --all-features`. - * Commit Message: `test(unilang_parser): Implement comprehensive test suite` - -* ⚫ **Increment 7: Documentation and Examples** - * (As per previous plan: crate-level, public API docs, example file). - * Verification Strategy: Manual review, `cargo test --doc --package unilang_instruction_parser`. - * Commit Message: `docs(unilang_parser): Add documentation and examples` - -## Requirements (for `unilang_instruction_parser` - Expanded) -* **R1: Dependency on `strs_tools::string::parser`:** Must use the itemizer from `strs_tools`. -* **R2: Unilang Specific Syntax:** Syntactic analyzer implements `unilang` grammar from spec. -* **R3: Dual Input Handling & Abstraction:** Public API supports `&str` and `&[&str]`. Internal logic must correctly map locations for both. -* **R4: Value Unescaping:** Argument values in `GenericInstruction` must be unescaped, likely using `Cow<'a, str>`. -* **R5: Precise Location-Aware Errors:** `ParseError` uses `SourceLocation` (distinguishing `StrSpan` and `SliceSegment`). -* **R6: No Command Definitions Dependency:** Purely syntactic. -* **R7: Comprehensive Test Coverage:** Including Test Matrix for various scenarios. -* **R8: Adherence to Workspace Rules:** Standard project cargo command rules. -* **R9: API Clarity:** Public API of `unilang_instruction_parser` is clear. -* **R10: Correct `ItemizerOptions` Configuration:** `Parser::new()` must correctly configure `strs_tools::ItemizerOptions` for `unilang`'s specific lexemes (quotes, escapes, delimiters, operators, comments). -* **R11: Handling of `strs_tools` Items:** The syntactic analyzer must correctly interpret the stream of `strs_tools::Item`s, typically ignoring `Whitespace` and `PotentialComment` kinds. -* **R12: Lifetime Management:** All `&'a str` and `Cow<'a, str>` in output structures must correctly borrow from the original input. -* **R13: Error Propagation:** Errors from `strs_tools::Itemizer` must be cleanly converted and propagated as `unilang_instruction_parser::ParseError`. - -## Notes & Insights -* The `strs_tools::string::parser::Item` struct should ideally contain `kind: ItemKind` where `ItemKind` itself can store the matched delimiter/operator string (e.g., `Delimiter(&'static str)`), making the `unilang_parser`'s job easier. This was noted for the `strs_tools` plan. -* The most complex part of this new plan is handling `SourceLocation` correctly, especially when itemizing `&[&str]` and then performing syntactic analysis on a potentially flattened list of `RichItem`s.

Focus is now on overall crate health, comprehensive testing, and adherence to `spec.md`. The `named_arg_with_quoted_escaped_value_location` test has a `qqq:` comment regarding its span that might need to be addressed if `strs_tools` behavior is confirmed. + * Crucial Design Rules: Adherence to specifications.

The span should accurately reflect the range of the *unescaped* value within the original input string. + +### Problem Statement / Justification +* The `strs_tools` crate's `SplitIterator` now correctly provides the *raw* content of quoted strings (excluding outer quotes) and the span of this raw content in the original input. +* The `unilang_instruction_parser` test `named_arg_with_quoted_escaped_value_location` currently fails. Analysis indicates that while the `start` of the `value_location` span might be calculated correctly (relative to the parser's internal logic), the `end` of this span appears to be calculated using the length of the *raw* token string received from `strs_tools`, rather than the length of the *unescaped* string. +* For example, if `strs_tools` provides a raw token `value with \\\"quotes\\\" and \\\\\\\\slash\\\\\\\\` (length 37) with its original span, `unilang_instruction_parser` unescapes this to `value with "quotes" and \\slash\\` (length 33). The `value_location` span should then reflect this unescaped length (33). The current failure shows an end point consistent with the raw length (37). + +### Proposed Solution / Specific Changes +* **In `unilang_instruction_parser` (likely within the argument parsing logic, specifically where `Value::String` and its `location` are constructed for named arguments):** + 1. When a quoted string token is received from `strs_tools` (or any tokenizer providing raw quoted content): + 2. Perform the unescaping of the raw string content. + 3. Calculate the length of the *unescaped* string. + 4. When constructing the `StrSpan` for `value_location`, ensure the `end` field is calculated based on the `start` field plus the length of the *unescaped* string. + * Example: If the determined `start_offset` for the value (e.g., after `arg_name::`) is `S`, and the unescaped string length is `L_unescaped`, then `value_location.end` should be `S + L_unescaped`. + +### Expected Behavior & Usage Examples (from Requester's Perspective) +* After the fix, the `named_arg_with_quoted_escaped_value_location` test in `unilang_instruction_parser/tests/argument_parsing_tests.rs` should pass. +* Specifically, for an input like `cmd arg_name::"value with \\\"quotes\\\" and \\\\\\\\slash\\\\\\\""`, if the parser determines the logical start of the value (after `::` and opening quote) to be, for instance, conceptually at original string index `X` (which the test seems to anchor at `9` relative to something), and the unescaped value is `value with "quotes" and \\slash\\` (length 33), then the `value_location` span should be `StrSpan { start: X_adjusted, end: X_adjusted + 33 }`. The current test expects `StrSpan { start: 9, end: 42 }`, which implies an unescaped length of 33. + +### Acceptance Criteria (for this proposed change) +* The `named_arg_with_quoted_escaped_value_location` test in `unilang_instruction_parser` passes. +* Other related argument parsing tests in `unilang_instruction_parser` continue to pass, ensuring no regressions. +* The `value_location` span for quoted arguments accurately reflects the start and end of the unescaped value content in the original input string. + +### Potential Impact & Considerations +* **Breaking Changes:** Unlikely to be breaking if the current behavior is a bug. This change aims to correct span reporting. +* **Dependencies:** No new dependencies. +* **Performance:** Negligible impact; involves using the correct length value (unescaped vs. raw) which should already be available post-unescaping. +* **Testing:** The existing `named_arg_with_quoted_escaped_value_location` test is the primary verification. Additional tests for various escaped sequences within quoted arguments could be beneficial to ensure robustness. + +### Alternatives Considered (Optional) +* None, as `strs_tools` is now correctly providing raw content and its span as per its design. The unescaping and subsequent span calculation for the unescaped value is the responsibility of `unilang_instruction_parser`. + +### Notes & Open Questions +* The exact location in `unilang_instruction_parser` code that needs modification will require inspecting its parsing logic for named arguments. It's where the raw token from the splitter is processed, unescaped, and its `StrSpan` is determined. \ No newline at end of file diff --git a/module/move/unilang_instruction_parser/tests/argument_parsing_tests.rs b/module/move/unilang_instruction_parser/tests/argument_parsing_tests.rs index 3daf4ec334..3c48c6808e 100644 --- a/module/move/unilang_instruction_parser/tests/argument_parsing_tests.rs +++ b/module/move/unilang_instruction_parser/tests/argument_parsing_tests.rs @@ -1,183 +1,352 @@ +//!

This indicates that both crates are trying to produce executables with the same names, leading to conflicts in the `target/debug/` (or `target/release/`) directory. While currently warnings, Cargo explicitly states this "may become a hard error in the future". This issue affects the cleanliness and reliability of workspace builds. + +### Proposed Solution / Specific Changes +* **Option 1 (Preferred): Rename binary targets in one of the crates.** + * For example, in `module/alias/cargo_will/Cargo.toml`, rename the `[[bin]]` sections to have unique names (e.g., `cargo-will-alias`, `will-alias`, `willbe-alias`). This is generally preferred if `cargo_will` is intended as an alias or wrapper. +* **Option 2: Configure `Cargo.toml` to compile separately.** + * If both crates are intended to produce binaries with the same names but are used in different contexts, their `Cargo.toml` files could be configured to compile them separately (e.g., by using `package.default-run` or by ensuring they are not built simultaneously in a way that causes collision). However, renaming is usually simpler. + +### Expected Behavior & Usage Examples (from Requester's Perspective) +* `cargo test --workspace` and `cargo build --workspace` should complete without any "output filename collision" warnings. +* The functionality of both `willbe` and `cargo_will` should remain as intended, with their respective binaries accessible by their (potentially new) names. + +### Acceptance Criteria (for this proposed change) +* `cargo test --workspace` and `cargo build --workspace` exit with code 0 and no "output filename collision" warnings. +* The binaries produced by `willbe` and `cargo_will` are distinct and functional. + +### Potential Impact & Considerations +* **Breaking Changes:** Renaming binary targets would be a breaking change for any scripts or users directly invoking `cargo-will`, `will`, or `willbe` from the affected crate by its old name. This should be communicated. +* **Dependencies:** No new dependencies. +* **Performance:** No significant performance impact. +* **Security:** No security implications. +* **Testing:** Existing tests for both `willbe` and `cargo_will` should continue to pass. + +### Notes & Open Questions +* Which crate should be prioritized for renaming? `cargo_will` seems like a more likely candidate for renaming its binaries if `willbe` is the primary tool. \ No newline at end of file
