LUMOS Development Execution Plan

Status: ✅ Phase 3.2 COMPLETE - VSCode Extension Ready Last Updated: 2025-11-18 Current Focus: Phase 3.3 Planning - Advanced Features (LSP, Validation, Publishing)

Overview

LUMOS is a type-safe schema language and code generator for Solana development, bridging TypeScript and Rust with seamless Borsh serialization.

Pipeline: .lumos → Parser → AST → IR → Rust + TypeScript code generation

Phase 1: Core Parser & Generators ✅ COMPLETED

Goal: Build fully functional .lumos parser and code generators Status: ✅ ALL SECTIONS COMPLETE Completion Date: 2025-01-17 Test Results: 50/50 tests passing (100%)

1.1 Parser Implementation ✅

Files:

packages/core/src/parser.rs - syn-based parser
packages/core/src/ast.rs - AST definitions
packages/core/src/transform.rs - AST → IR transformer
packages/core/src/ir.rs - Intermediate representation

Features:

Rust-style #[attribute] syntax
Full type system: primitives, arrays, optionals, user-defined types
Metadata support: #[solana], #[account], #[key], #[max(n)]
Tested with 5 real-world example schemas

Tests: 21 unit + integration tests passing

1.2 Rust Code Generator ✅

Files:

packages/core/src/generators/rust.rs (340 lines)
packages/core/tests/test_rust_generator.rs (170 lines)

Features:

Context-aware generation: Detects Anchor usage at module level
Smart imports:
- anchor_lang::prelude::* for modules with any #[account] struct
- borsh::{BorshSerialize, BorshDeserialize} for pure Borsh modules
Intelligent derives:
- NO derives for #[account] structs (Anchor provides them)
- AnchorSerialize/AnchorDeserialize for non-account structs in Anchor modules
- BorshSerialize/BorshDeserialize for pure Borsh modules
Type mapping:
- Pubkey → Pubkey
- PublicKey → Pubkey
- Signature → String (base58)
- [T] → Vec<T>
- Option<T> → Option<T>

Generated Code Example:

// Auto-generated by LUMOS
use anchor_lang::prelude::*;
use solana_program::pubkey::Pubkey;

#[account]
pub struct UserAccount {
    pub wallet: Pubkey,
    pub balance: u64,
}

Tests: 11 unit + integration tests passing

1.3 TypeScript Code Generator ✅

Files:

packages/core/src/generators/typescript.rs (387 lines)
packages/core/tests/test_typescript_generator.rs (237 lines)

Features:

TypeScript interface generation
Complete Borsh schema generation for serialization
Type mapping:
- u8, u16, u32, u64, i8, i16, i32, i64 → number
- u128, i128 → bigint
- bool → boolean
- String → string
- Pubkey, PublicKey → PublicKey
- Signature → string
- [T] → T[]
- Option<T> → T | undefined (with ? marker)
Smart imports:
- import { PublicKey } from '@solana/web3.js'
- import * as borsh from '@coral-xyz/borsh'

Generated Code Example:

// Auto-generated by LUMOS
import { PublicKey } from '@solana/web3.js';
import * as borsh from '@coral-xyz/borsh';

export interface UserAccount {
  wallet: PublicKey;
  balance: number;
}

export const UserAccountSchema = borsh.struct([
  borsh.publicKey('wallet'),
  borsh.u64('balance'),
]);

Tests: 12 unit + integration tests passing

1.4 End-to-End Integration Testing ✅

Files:

packages/core/tests/test_e2e.rs (352 lines)

Test Coverage:

Rust Compilation Tests (4):
- Gaming schema (mixed: 3 #[account] + 1 non-account)
- NFT Marketplace (mixed)
- DeFi Staking (mixed)
- DAO Governance (all #[account])
- Method: Creates temporary Cargo projects, runs cargo check
TypeScript Validation Tests (2):
- Gaming schema syntax validation
- NFT Marketplace syntax validation
Complete Pipeline Test (1):
- Full flow: parse → IR → Rust + TypeScript → compile
Type Compatibility Test (1):
- Verifies Rust ↔ TypeScript type matching
- Confirms Borsh serialization compatibility

Tests: 8 E2E tests passing

Phase 1 Summary

Key Technical Achievements

Context-Aware Code Generation
- Automatically detects Anchor framework usage
- Prevents import conflicts in mixed modules
- Smart derive selection based on context
Production-Ready Output
- Clean, idiomatic code in both languages
- Proper imports and formatting
- Comprehensive type safety
Borsh Serialization Compatibility
- Matching schemas between Rust and TypeScript
- Type-safe serialization/deserialization
- Support for all Solana-specific types
Comprehensive Testing
- 50/50 tests passing (100% pass rate)
- E2E verification with actual compilation
- All 5 example schemas validated

Technical Challenges Solved

1. Borsh Import Ambiguity

Problem: Modules with both #[account] and non-#[account] structs had conflicting imports. Solution: If ANY struct uses #[account], use Anchor prelude for entire module; non-account structs use AnchorSerialize/AnchorDeserialize.

2. Derive Conflicts

Problem: Manual derives conflicted with Anchor's automatic derives. Solution: Context-aware derive generation - no derives for #[account] structs.

3. Signature Type Mapping

Problem: solana_program::signature::Signature import path doesn't exist. Solution: Map Signature → String (base58 representation) in both languages.

Phase 2: CLI & Developer Tools ✅ COMPLETED

}

✅ Added EnumDefinition and EnumVariantDefinition types:

pub enum EnumVariantDefinition {
    Unit { name: String },
    Tuple { name: String, types: Vec<TypeInfo> },

export const GameInstructionSchema = borsh.rustEnum([
  borsh.struct([
    borsh.publicKey('authority'),
    borsh.u32('max_players'),
  ], 'Initialize'),
  borsh.struct([
    borsh.publicKey('player'),
    borsh.u64('new_score'),
  ], 'UpdateScore'),
]);

- Bidirectional code generation (Rust ↔ TypeScript)
- Borsh serialization compatibility guaranteed
Type-Safe Discriminated Unions
- TypeScript kind field enables type narrowing

Example Schemas Tested

All 6 example schemas successfully generate and compile:

Gaming (examples/gaming/schema.lumos)
- Player accounts, items, leaderboards, match results
- Mixed: 3 #[account] + 1 non-account struct
NFT Marketplace (examples/nft-marketplace/schema.lumos)
- Marketplace, listings, metadata, receipts
- Signature type handling
DeFi Staking (examples/defi-staking/schema.lumos)
- Staking pools, staker accounts, events
- Complex optional types
DAO Governance (examples/dao-governance/schema.lumos)
- DAO config, proposals, votes, members
- All structs use #[account]
Token Vesting (examples/token-vesting/schema.lumos)
- Vesting schedules, beneficiaries
- Time-based logic
Enums (examples/enums/schema.lumos) ✨ NEW
- Comprehensive enum patterns (8 different use cases)
- Unit enums (state machines)
