assumptions**. --- -## �️ Proven Patterns for Complex Tasks (FerrisScript Learnings) - -**When to Use These Patterns**: Multi-hour implementations (4+ hours), cross-crate changes, reflection/metadata systems, or features touching multiple pipeline stages. - -### Pattern 1: Checkpoint Methodology ✅ - -**Source**: Phase 4.5 struct literal implementation (50% faster than Phase 4) - -**Problem**: Large features are hard to pause/resume, risky to implement all-at-once - -**Solution**: Break into 8 structured checkpoints with natural test/commit points - -**Checkpoint Structure**: - -1. **Checkpoint 1-2**: Foundation (AST nodes, basic parsing) -2. **Checkpoint 3-4**: Core logic (type checking, validation) -3. **Checkpoint 5-6**: Integration (runtime, conversions) -4. **Checkpoint 7**: Error handling + recovery -5. **Checkpoint 8**: Integration tests + documentation - -**Benefits**: - -- Natural pause points every 15-30 minutes -- Easy to resume work (clear next checkpoint) -- Early bug detection (test after each checkpoint) -- Clear progress tracking (8/8 checkpoints = done) - -**Example Application** (Phase 4.5): - -- Checkpoint 1: AST StructLiteral node -- Checkpoint 2: Parser basic syntax (`Type { }`) -- Checkpoint 3: Parser field parsing (`field: value`) -- Checkpoint 4: Type checker validate type name -- Checkpoint 5: Type checker validate fields -- Checkpoint 6: Runtime evaluate literal -- Checkpoint 7: Error recovery (missing fields) -- Checkpoint 8: Integration tests (all types) - -**How to Apply**: - -- For 4-6 hour feature: 8 checkpoints (~30 min each) -- For 10+ hour feature: 3 sub-phases × 8 checkpoints each (24 total) -- Test after each checkpoint (no commit until passing) -- Document checkpoint completion in execution plan - -**Metrics**: 50% faster implementation, 3 bugs caught early (vs late-stage rework) - ---- - -### Pattern 2: MVP + Robustness Split ✅ - -**Source**: Phase 4.5 robustness testing (39 tests added after MVP) - -**Problem**: Trying to cover all edge cases during MVP slows progress - -**Solution**: Separate MVP implementation from robustness testing - -**MVP Phase** (Focus on happy path): - -- Basic functionality working -- Core tests passing (feature works) -- Integration with existing systems - -**Robustness Phase** (Focus on edge cases): - -- Missing/wrong/extra data -- Type coercion and conversions -- Error recovery and diagnostics -- Integration examples -- Performance edge cases - -**Benefits**: - -- MVP completes faster (don't get stuck on edge cases) -- MVP proves feasibility early -- Robustness testing validates production-readiness -- Zero bugs found during robustness = good MVP quality - -**Example Application** (Phase 4.5): - -**MVP** (2.5 hours): - -- Struct literal syntax working -- 31 tests re-enabled -- 548 tests passing - -**Robustness** (3 hours): - -- 27 compiler edge case tests -- 12 runtime execution tests -- 5 integration examples -- 587 tests passing (+39) - -**How to Apply**: - -- MVP first: Get feature working, basic tests passing -- Commit MVP: "feat: [Feature] MVP complete" -- Robustness next: Add edge case tests, examples -- Commit robustness: "feat: [Feature] complete - robustness testing" - -**Metrics**: 0 bugs found during robustness testing (good MVP indicator) - ---- - -### Pattern 3: Error Code Semantic Grouping ✅ - -**Source**: Phase 4.5 struct literal errors (E701-E710 range) - -**Problem**: Large error code ranges (E100-E199) hard to navigate - -**Solution**: Allocate semantic ranges for feature families - -**Grouping Strategy**: - -- E70x: Struct literal errors (all types) -- E801-E815: Export annotation errors (future) -- Semantic > unique codes per type - -**Benefits**: - -- Easy to find related errors (all struct errors start with E7) -- Can reuse codes across similar types (E701 = unknown field on ANY type) -- Clear documentation patterns (E70x documentation section) - -**Example Application** (Phase 4.5): - -- E701-E703: Unknown field (Color, Rect2, Transform2D) -- E704-E706: Missing field (reserved for future) -- E707-E710: Type mismatch (reserved for future) -- Reused E205 for Vector2 (existing error code) - -**How to Apply**: - -- Allocate 10-15 code range for feature -- Group by category (parser, type checker, runtime) -- Reuse codes across similar types -- Document range in ERROR_CODES.md - -**Anti-Pattern**: E701 = Color field, E702 = Rect2 field → hard to remember - ---- - -### Pattern 4: Integration Examples as Tests ✅ - -**Source**: Phase 4.5 integration examples (5 .ferris files) - -**Problem**: Unit tests don't validate real-world usage patterns - -**Solution**: Create example files demonstrating practical patterns - -**Example File Structure**: - -```rust -// examples/struct_literals_color.ferris -# TEST: Color RGBA manipulation -# CATEGORY: Type System -# DESCRIPTION: Demonstrates Color struct literals with integer coercion -# EXPECT: success - -// Real-world code here -let red = Color { r: 1, g: 0, b: 0, a: 1 }; // Integer coercion -``` - -**Benefits**: - -- Examples serve as documentation -- Examples validate real-world patterns -- Examples can be used in test harness (metadata protocol) -- Examples show best practices - -**Example Application** (Phase 4.5): - -- `struct_literals_color.ferris` - RGBA manipulation -- `struct_literals_vector2.ferris` - Vector math -- `struct_literals_rect2.ferris` - Boundaries -- `struct_literals_transform2d.ferris` - Transformations -- `struct_literals_functions.ferris` - Function patterns - -**How to Apply**: - -- Create 3-5 example files per feature -- Include TEST metadata for harness integration -- Demonstrate practical patterns (not just syntax) -- Add to examples/ directory - -**Note**: Examples may not run through test harness immediately (Phase 5 work), but serve as reference - ---- - -### Pattern 5: Sub-Phase Decomposition ✅ - -**Source**: Phase 5 execution plan (3 sub-phases for @export) - -**Problem**: 20+ hour features too large for single-session implementation - -**Solution**: Decompose into independent sub-phases - -**Sub-Phase Structure**: - -1. **Sub-Phase 1: Parser & AST** (4-6 hours) - - Lexer tokens - - Parser grammar extension - - AST node definitions - - 8 checkpoints - -2. **Sub-Phase 2: Type Checker & Validation** (5-7 hours) - - Semantic validation - - Error code implementation - - Compatibility matrix - - 8 checkpoints - -3. **Sub-Phase 3: Runtime & Integration** (9-13 hours) - - Metadata storage - - Cross-crate integration - - Godot binding - - 8 checkpoints - -**Benefits**: - -- Each sub-phase can be implemented in separate session -- Clear dependencies (must do Phase 1 before Phase 2) -- Natural commit points (commit after each sub-phase) -- Parallel work possible (if independent) - -**Example Application** (Phase 5): - -- Session 1: Parser + AST (4-6 hours) -- Session 2: Type Checker (5-7 hours) -- Session 3: Runtime + Godot (9-13 hours) -- Total: 18-26 hours across 3 sessions - -**How to Apply**: - -- For 10+ hour feature: Split into 3 sub-phases -- For 20+ hour feature: Split into 3-4 sub-phases -- Each sub-phase has 8 checkpoints -- Document sub-phase dependencies in execution plan - -**Metrics**: Phase 5 estimate = 23-31 hours → 3 sub-phases × 8 checkpoints = 24 total - ---- - -### Pattern 6: Test-First Checkpoint Validation ✅ - -**Source**: Phase 4.5 zero bugs during robustness testing - -**Problem**: Late-stage bugs require rework and context switching - -**Solution**: Write tests before implementation, validate at each checkpoint - -**Test-First Workflow**: - -1. Write test for checkpoint functionality -2. Run test (expect failure) -3. Implement checkpoint code -4. Run test (expect pass) -5. Move to next checkpoint - -**Benefits**: - -- Tests catch issues immediately -- Clear success criteria (test passes = checkpoint done) -- Zero bugs found during robustness = good quality -- Tests serve as specification - -**Example Application** (Phase 4.5): - -- Checkpoint 3: Type checker validate type name - - Test: `test_struct_literal_wrong_type_name()` (write first) - - Implement: Type name validation (implement second) - - Result: Test passes → checkpoint complete - -**How to Apply**: - -- Write test before each checkpoint -- Run test after implementation -- Don't move to next checkpoint until tests pass -- Document test count in checkpoint tracking - -**Metrics**: 0 bugs found during robustness testing = MVP quality validated - ---- - -### Pattern 7: Execution Plan Template ✅ - -**Source**: Phase 5 execution plan (comprehensive planning doc) - -**Problem**: Ad-hoc planning leads to scope creep and missed requirements - -**Solution**: Use structured execution plan template - -**Required Sections**: - -1. **Executive Summary** (goal, scope, why deferred if applicable) -2. **Effort Estimation** (breakdown by category, total hours) -3. **Sub-Phase Breakdown** (if 10+ hours) -4. **Checkpoint Tracking** (24 total for complex features) -5. **Testing Strategy** (MVP + robustness split) -6. **Error Code Definitions** (allocated range) -7. **File Modifications** (what will change) -8. **Success Criteria** (functional + quality + integration) -9. **Learnings from Previous Phases** (apply proven patterns) -10. **Implementation Notes** (technical approach) - -**Benefits**: - -- Complete planning before implementation -- Clear scope and requirements -- Effort estimation for scheduling -- Pattern reuse (apply Phase 4.5 learnings) - -**Example Application** (Phase 5): - -- 23-31 hour estimate (6 categories) -- 3 sub-phases (Parser, Type Checker, Runtime) -- 24 checkpoints (8 per sub-phase) -- 51 total tests (30 MVP + 21 robustness) -- Learnings from Phase 4.5 applied - -**How to Apply**: - -- Create execution plan before implementation -- Use PHASE_X_EXECUTION_PLAN.md template -- Document all decisions and assumptions -- Update plan during implementation - ---- - -### When to Use These Patterns - -**Use Checkpoint Methodology When**: - -- Feature will take 4+ hours -- Multiple pipeline stages affected (parser + type checker + runtime) -- Easy to get lost in implementation details - -**Use MVP + Robustness Split When**: - -- Feature has many edge cases -- Want to prove feasibility quickly -- Risk of scope creep - -**Use Sub-Phase Decomposition When**: - -- Feature will take 10+ hours -- Can break into independent phases -- Want to implement across multiple sessions - -**Use Test-First Validation When**: - -- Feature has clear specifications -- Want to minimize bugs -- Need confidence in implementation quality - -**Use All Patterns Together When**: - -- Complex feature (20+ hours) -- Cross-crate changes -- Reflection/metadata systems -- High-risk implementation - -**Example**: Phase 5 @export uses ALL patterns: - -- ✅ Checkpoint methodology (24 checkpoints) -- ✅ MVP + robustness split (30 MVP + 21 robustness) -- ✅ Sub-phase decomposition (3 sub-phases) -- ✅ Error code grouping (E801-E815) -- ✅ Integration examples (3 files) -- ✅ Test-first validation (51 tests) -- ✅ Execution plan template (comprehensive doc) - ---- - -## �🎭 Your Role & Expertise +## 🎭 Your Role & Expertise You are a **senior software engineer** with: diff --git a/.gitignore b/.gitignore index e896247..26fe42e 100644 --- a/.gitignore +++ b/.gitignore @@ -25,7 +25,6 @@ node_modules/ # Temporary files (PR bodies, scripts) /temp/ -.github/PR_DESCRIPTION.md # OS Thumbs.db diff --git a/CHANGELOG.md b/CHANGELOG.md index e009c96..240cb6b 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -23,94 +23,6 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 --- -## [0.0.4] - 2025-10-08 - -**Codename**: "Godot API Expansion" 🔔🌳 - -This release significantly expands FerrisScript's Godot integration, adding signal support, lifecycle callbacks, and node query functions.

Following Established Patterns ✅ - -**Pattern**: Vector2 implementation provided excellent blueprint - -- **AST**: Type enum addition pattern clear -- **Type Checker**: Field access validation reusable -- **Runtime**: Value enum + field get/set established -- **Testing**: Test structure consistent across types - -**Evidence**: Phase 4 completed in focused session with minimal refactoring - -**Lesson**: Invest in reference implementations early - they compound value - ---- - -#### 2. Nested Type Handling (Box) ✅ - -**Challenge**: Rect2 and Transform2D contain Vector2 fields - -- **Solution**: Use `Box` for nested types to avoid recursive enum size issues -- **Pattern**: - - ```rust - pub enum Value { - Color { r: f32, g: f32, b: f32, a: f32 }, - Rect2 { position: Box, size: Box }, // ✅ Boxed - Transform2D { position: Box, rotation: f32, scale: Box }, - } - ``` - -**Evidence**: No compiler errors about "infinite size", runtime performance unaffected - -**Lesson**: Nested types in enums require heap indirection - use Box proactively - ---- - -#### 3. Error Code Pre-Allocation ✅ - -**Strategy**: Reserve error code ranges during planning phase - -- E701-E710: Reserved for Phase 4 types before implementation -- Clear semantic grouping (E701-E703: field access, E704-E706: construction, E707-E710: type mismatches) - -**Benefits**: - -- No code conflicts during implementation -- Clear error categorization -- Easy to reference in tests -- Documentation writes itself - -**Lesson**: Pre-allocate error codes in blocks of 10 during planning - ---- - -#### 4. Type System Extensibility Validated ✅ - -**Achievement**: Added 3 new types without modifying existing type system architecture - -- Type enum addition: Straightforward -- Field access: Generic pattern scaled -- Runtime execution: No fundamental changes needed - -**Evidence**: 517 tests passing, no regressions - -**Lesson**: Well-designed type system pays dividends - invest in architecture upfront - ---- - -### 🚧 What Could Be Improved - -#### 1. Test-First Development Gap ⚠️ - -**Problem**: Wrote tests before implementing struct literal syntax - -- 30 tests commented out immediately after writing -- Tests had hidden dependency on unimplemented parser feature -- Reduced validation capability during development - -**Better Approach**: - -1. Implement struct literals FIRST (or use workaround syntax) -2. Write tests that can actually run -3.

Dependency Planning ⚠️ - -**Problem**: Didn't identify struct literal syntax as prerequisite - -- Assumed function parameters were sufficient testing mechanism -- Underestimated value of direct construction tests -- Created "blocked" work (30 tests waiting) - -**Better Approach**: - -1.

Checkpoint Methodology ✅ - -**Approach**: 8 structured checkpoints (Modify → Validate → Test → Document) - -- Checkpoint 1: AST modification (10 min) - Added StructLiteral variant -- Checkpoint 2: Parser implementation (30 min) - Uppercase heuristic prevents `if x {}` ambiguity -- Checkpoint 3: Type checker validation (45 min) - All 4 types validated -- Checkpoint 4: Runtime evaluation (30 min) - Value construction working -- Checkpoints 5-8: Incremental test validation (35 min total) - -**Benefits**: - -- Early issue detection (caught uppercase heuristic bug in Checkpoint 2) -- Clear progress tracking -- Easy to pause/resume work -- Natural documentation points - -**Evidence**: **2.5 hours total** from start to 548 tests passing, **3 bugs caught early** - -**Lesson**: Checkpoint methodology prevents time loss from late-stage bugs - ---- - -#### 2. Error Code Reuse Strategy ✅ - -**Pattern**: Reuse existing error codes across similar types - -- **E704**: Missing field (Color, Vector2) -- **E705**: Missing field (Rect2) -- **E706**: Missing field (Transform2D) -- **E701-E703**: Unknown field (respective types) -- **E707-E709**: Type mismatch (respective types) - -**Benefits**: - -- Semantic grouping maintained -- No error code explosion -- Clear documentation patterns -- Easy to remember (E70x = struct literal errors) - -**Evidence**: 27 compiler robustness tests cover all error codes - -**Lesson**: Error code ranges don't need 1:1 mapping to features - semantic grouping more valuable - ---- - -#### 3. Robustness Testing Strategy ✅ - -**Approach**: Test edge cases after MVP implementation - -- **27 compiler tests** (missing fields, wrong types, extra fields, coercion) -- **12 runtime tests** (execution, functions, loops, conditionals, chains) -- **5 integration examples** (real-world patterns in `.ferris` files) - -**Coverage**: - -- ✅ Missing required fields (Vector2, Color, Rect2, Transform2D) -- ✅ Unknown/extra fields -- ✅ Type mismatches (string → numeric, primitive → Vector2) -- ✅ Integer coercion (i32 → f32 in Color/Vector2) -- ✅ Nested field access chains (`rect.position.x`) -- ✅ Function parameters and returns -- ✅ Conditionals and loops with struct literals - -**Evidence**: Test count increased **548 → 587 (+39 tests, +7% coverage)** - -**Lesson**: Robustness testing after MVP validates production-readiness - ---- - -#### 4. Test-First Validation ✅ - -**Achievement**: Re-enabled 31 Phase 4 tests after struct literal implementation - -- **Original state**: 30+ tests commented out (Phase 4 blocked) -- **Post-MVP**: All tests passing -- **Validation**: Feature works as originally designed - -**Evidence**: Zero test modifications needed - implementation matched original expectations - -**Lesson**: Well-designed test suite validates implementation correctness - ---- - -### 🚧 What Could Be Improved - -#### 1. Nested Literal Limitation ⚠️ - -**Problem**: Nested struct literals not supported in MVP - -```rust -// ❌ Not supported (MVP limitation): -let rect = Rect2 { - position: Vector2 { x: 0.0, y: 0.0 }, // Error: parser doesn't handle nesting - size: Vector2 { x: 100.0, y: 50.0 } -}; - -// ✅ Workaround required: -let pos = Vector2 { x: 0.0, y: 0.0 }; -let size = Vector2 { x: 100.0, y: 50.0 }; -let rect = Rect2 { position: pos, size: size }; -``` - -**Impact**: - -- Slightly more verbose syntax -- Extra variable declarations needed -- Still fully functional, just less convenient - -**Better Approach**: - -- Implement nested literals as part of MVP (adds ~1-2 hours) -- OR document limitation clearly in examples -- Defer to Phase 4.6 if time-constrained - -**Lesson**: MVP scope decisions have UX trade-offs - document limitations explicitly - ---- - -#### 2. Duplicate Field Handling ⚠️ - -**Behavior**: Parser accepts duplicate fields (last value wins) - -```rust -// Currently accepted (no error): -let v = Vector2 { x: 10.0, x: 20.0, y: 30.0 }; // x = 20.0 (last wins) -``` - -**Pros**: - -- Consistent with JSON/Rust behavior -- Simple implementation -- No parser complexity - -**Cons**: - -- Likely programmer error (typo/copy-paste) -- Silent bug potential -- Not caught until runtime (if at all) - -**Better Approach**: - -- Add duplicate field detection in parser -- Error code E7xx reserved for duplicates -- Fail fast at compile time - -**Lesson**: Silent failures are worse than inconvenient errors - fail fast - ---- - -#### 3. Godot Test Harness Integration Gap ⚠️ - -**Problem**: Integration examples can't run through `ferris-test` tool yet - -- Examples created: `struct_literals_color.ferris`, `struct_literals_vector2.ferris`, etc. -- Compilation works -- But Godot test harness doesn't compile scripts correctly - -**Root Cause**: Godot integration uses different compilation pipeline - -**Workaround**: Examples validated via unit tests - -**Better Approach**: - -- Test harness integration in Phase 5 -- OR use simpler compile-only validation for examples -- Document "examples are illustrative, not executable yet" - -**Lesson**: Integration layers have independent testing requirements - ---- - -### 🎓 Actionable Takeaways - -#### For Phase 5 (@export) - -1. ✅ **Use checkpoint methodology** - 8 checkpoints worked perfectly -2. ✅ **Test edge cases explicitly** - Robustness tests found no bugs (good MVP quality) -3. ✅ **Document limitations upfront** - Nested literals limitation documented -4. ✅ **Re-enable blocked tests early** - 31 tests passing validates design -5. ✅ **Separate MVP from polish** - Nested literals deferred without impact - -#### For Future Features - -1. ✅ **Robustness test template** - Edge cases, error paths, coercion, nesting -2. ✅ **Compiler + Runtime testing** - Both layers need coverage -3. ✅ **Error code reuse** - Semantic grouping > unique codes -4. ✅ **Integration examples** - Show real-world usage patterns -5. ✅ **MVP scope discipline** - 2.5 hours for working feature > 5 hours for perfect feature - ---- - -### 📊 Metrics - -| Metric | Phase 4 | Phase 4.5 MVP | Phase 4.5 Complete | -|--------|---------|---------------|-------------------| -| Implementation Time | ~4-5 hours | **2.5 hours** | 5 hours | -| Tests Written | 30 (commented) | 31 re-enabled | +39 robustness | -| Tests Passing | 517 | 548 | **587** | -| Checkpoints | None | 8 | 8 | -| Bugs Found During | ~3 | **3 (caught early)** | 0 | -| Files Modified | 5 | 4 core + 7 docs | +5 examples | -| LOC Added | ~400 | ~250 core + 2500 docs | +150 tests | - -**Key Insight**: Checkpoint methodology caught bugs early (no late-stage rework), resulting in **50% faster implementation** than Phase 4 - ---- - -### 🔬 Testing Insights - -#### Error Code Coverage - -- **E704-E706**: Missing field validation (3 types) -- **E701-E703**: Unknown field validation (3 types) -- **E707-E709**: Type mismatch validation (3 types) -- **E205, E708**: Reused for Vector2/Rect2 field errors - -#### Test Categories - -**Compiler (27 tests)**: - -- 4 Vector2 (missing, wrong type, extra field, coercion) -- 7 Color (all 4 fields missing, wrong type, unknown, coercion) -- 5 Rect2 (missing, wrong type, extra) -- 6 Transform2D (missing, wrong type, extra, coercion) -- 5 Mixed (type mismatch, functions, expressions, duplicates) - -**Runtime (12 tests)**: - -- 4 Type execution (Vector2, Color, Rect2, Transform2D) -- 2 Function tests (parameters, returns) -- 1 Nested access chain test -- 2 Control flow tests (conditional, loop) -- 2 Coercion tests (integer → float) -- 1 Complex expression test - -**Integration (5 examples)**: - -- struct_literals_color.ferris -- struct_literals_vector2.ferris -- struct_literals_rect2.ferris -- struct_literals_transform2d.ferris -- struct_literals_functions.ferris - ---- - -### 🚀 Next Steps - -**Immediate** (Post-MVP): - -1.

This creates an infinite loop where the parser repeatedly processes the same bad token. The `advance()` call before `synchronize()` guarantees forward progress. - -**Application**: Any compiler implementing panic-mode error recovery must follow this pattern. Document it prominently in implementation guides. - ---- - -## ✅ Quality Gates - Strict Standards Prevent Tech Debt - -### Established Quality Standards (v0.0.3) - -**Strict Clippy Mode**: - -```bash -cargo clippy --workspace --all-targets --all-features -- -D warnings -``` - -**Key Insight**: Standard `cargo clippy` is **too lenient** for production quality. Strict mode (`-D warnings`) catches: - -- Issues in test code (not just main code) -- Issues in benchmark code -- Issues in example code -- Issues with all feature combinations - -**Impact**: Phase 1 passed standard clippy but failed strict mode, revealing: - -- `useless_vec` warnings in test code (should use arrays) -- Deprecated `criterion::black_box` (should use `std::hint::black_box`) - -**Recommendation**: Establish strict clippy as the **only** acceptable standard from project start. Easier to maintain than to retroactively fix. - -### Format Before Commit - -**Standard**: - -```bash -cargo fmt --all -``` - -**Why**: Prevents formatting diff noise in code reviews, maintains consistency, shows professionalism. - -**Integration**: Add to: - -- Pre-commit hooks (automated) -- CI/CD validation (gated) -- Contributor checklists (documented) - -### Documentation Validation - -**Tools**: - -```bash -npm run docs:lint # Markdownlint -npx markdown-link-check # Link validation -``` - -**Discovery**: Found 11 broken links in v0.0.3 planning docs during Phase 1 validation. Systematic link checking prevents: - -- Broken navigation in documentation -- 404 errors for users -- Outdated cross-references - -**Best Practice**: Run link checks on ALL modified markdown files before commit, not just at release time. - ---- - -## 🧪 Testing Strategies - -### Integration Tests > Unit Tests (For User-Facing Features) - -**Discovery**: For features like error messages and suggestions, integration tests (full compiler pipeline) are more valuable than unit tests (algorithm internals). - -**Rationale**: - -- Users see **output** (error messages), not **algorithm behavior** (Levenshtein distance) -- Integration tests verify the complete user experience -- Unit tests only verify internal correctness - -**Example**: - -```rust -// ❌ Less Valuable: Unit test of suggestion algorithm -#[test] -fn test_levenshtein_distance() { - assert_eq!(levenshtein("hello", "helo"), 1); -} - -// ✅ More Valuable: Integration test of user-visible output -#[test] -fn test_typo_suggestion() { - let result = compile("let x: i32 = 5; let y = palyer;"); - assert!(result.err().unwrap().contains("did you mean 'player'?")); -} -``` - -**Application**: For user-facing features (error messages, diagnostics, suggestions), write integration tests first. Add unit tests only if algorithm complexity justifies them. - -### Test Both Success and Failure Paths - -**Discovery**: When implementing error recovery, must test that: - -1. ✅ Recovery works (parser continues after errors) -2. ✅ Valid code still compiles (recovery doesn't break normal parsing) - -**Example**: - -```rust -// Test recovery works -#[test] -fn test_parser_recovers_from_missing_semicolon() { - let code = "let x = 5\nlet y = 10;"; // Missing semicolon - let result = parse(code); - assert!(result.errors.len() > 0); // Error detected - assert!(result.program.is_some()); // But parsing continued -} - -// Test valid code unaffected -#[test] -fn test_valid_code_still_works() { - let code = "let x = 5;\nlet y = 10;"; // Valid code - let result = parse(code); - assert_eq!(result.errors.len(), 0); // No errors - assert!(result.program.is_some()); // Parsing succeeded -} -``` - -**Rationale**: Error recovery can accidentally break normal parsing if sync points are too aggressive or if panic mode isn't cleared properly. - ---- - -## 🔧 Debugging Techniques - -### Debug Output First, Assertions Second - -**Problem**: Integration test fails with "Expected error message X, got Y" - -**Wrong Approach**: - -```rust -assert!(error.contains("Expected ';'")); // Fails, no idea what actual message is -``` - -**Right Approach**: - -```rust -println!("Actual error: {}", error); // See what it actually says -// Output: "Error[E108]: Expected token\nExpected ;, found let" -assert!(error.contains("Expected")); // Now write flexible assertion -``` - -**Rationale**: Exact error message strings change during development. Debug output reveals actual format so you can write flexible assertions that check for patterns rather than exact strings. - -### Verify Data Structures Before Testing - -**Problem**: Test fails with "Token::Int(1) doesn't exist" - -**Discovery**: FerrisScript lexer uses `Token::Number(f32)` for all numeric literals, not separate `Token::Int(i32)` and `Token::Float(f32)` variants. - -**Lesson**: When writing parser tests, **always check the actual token enum definition** in the lexer. Don't assume token variant names - verify them to avoid cryptic compilation errors. - -**Application**: Before writing tests for any data structure (AST nodes, tokens, types), read the actual definitions in source code. - ---- - -## 📐 Adaptive Algorithms - -### Threshold Tuning Through Testing - -**Discovery**: String similarity thresholds must adapt to identifier length. Short names need strict edit distance, long names need percentage similarity. - -**Implementation**: - -```rust -fn is_similar(candidate: &str, target: &str) -> bool { - let distance = levenshtein(candidate, target); - - if target.len() <= 8 { - // Short names: strict edit distance - distance <= 2 || (target.len() <= 4 && distance <= 1) - } else { - // Long names: percentage similarity - let similarity = 1.0 - (distance as f32 / target.len() as f32); - similarity >= 0.70 - } -} -``` - -**Lesson**: Don't guess at algorithm parameters. Write comprehensive tests first, then adjust parameters until tests pass with good precision/recall balance. - -**Application**: For any algorithm with tunable parameters (thresholds, weights, limits), use test-driven parameter tuning rather than intuition. - ---- - -## 📝 Documentation Best Practices - -### Document Critical Bugs Thoroughly - -**Discovery**: When you find a severe bug (like infinite loop in error recovery), document it with: - -1. **Symptoms**: What the user sees (memory consumption, hang) -2. **Root Cause**: Why it happened (synchronize without advance) -3. **Fix**: What changed (add advance before synchronize) -4. **Prevention**: How to avoid in future (always advance first) - -**Example Documentation** (from Phase 3C): - -> **Critical Infinite Loop Bug**: Initial implementation caused infinite memory consumption when parser encountered unexpected top-level tokens. Root cause: Called `synchronize()` without first advancing past the bad token. If `synchronize()` returned immediately (token was already at sync point), parser stayed at same position forever, repeatedly processing same token. -> -> **Fix**: Added mandatory `self.advance()` call before `synchronize()` in error recovery path. This guarantees forward progress even if sync point is reached immediately. - -**Rationale**: These insights prevent similar bugs in future work. Future contributors can learn from past mistakes without repeating them. - ---- - -## 🎯 Best Practices Summary - -**From v0.0.3 Development**: - -1. **Error Recovery**: Always advance before synchronize (prevent infinite loops) -2. **Quality Gates**: Use strict clippy (`-D warnings`) from day one -3. **Testing Priority**: Integration tests > unit tests for user-facing features -4. **Test Coverage**: Test both error paths AND success paths -5. **Debugging**: Print actual values before writing assertions -6. **Algorithms**: Tune parameters through testing, not intuition -7. **Documentation**: Document severe bugs thoroughly (symptoms, cause, fix, prevention) -8. **Verification**: Verify data structure definitions before writing tests -9. **Format Consistency**: Run `cargo fmt --all` before every commit -10. **Link Validation**: Check markdown links before committing documentation - -**Application**: These practices apply to all future development phases and versions.

Phased Implementation Approach ✅ - -**Strategy**: Implement Bundle 7 in two phases (verification stub → full integration) - -**Phase 1** (10 min): - -- Added `#[class(tool)]` annotation -- Implemented logging stubs for `get_property()` and `set_property()` -- Verified hooks are called correctly -- **Commit**: 8a65223 - -**Phase 2** (35 min): - -- Replaced stubs with full runtime integration -- 65+ lines of comprehensive documentation -- Connected to runtime storage -- **Commit**: 55ba87f - -**Benefits**: - -- Early validation of API usage (hooks actually called) -- Clear checkpoint if issues arise -- Reduced risk for complex integration -- Clean git history showing progression - -**Evidence**: No API errors, implementation smooth - -**Lesson**: **Use phased approach for risky integrations:** - -1. **Verification stub**: Minimal implementation to validate API -2. **Full integration**: Complete logic with confidence -3. **Each phase is a commit**: Clear progression, easy rollback - -**When to Use**: - -- New API with unclear behavior -- Complex integration across modules -- High-risk changes that might need rollback - ---- - -#### 3. Fallback Pattern for Coexistence ✅ - -**Pattern**: Property hooks use `Option` and `bool` return types for fallback - -**Implementation**: - -```rust -fn get_property(&self, property: StringName) -> Option { - if let Some(env) = &self.env { - if let Ok(value) = env.get_exported_property(&prop_name) { - return Some(value_to_variant(&value)); // ✅ We handle it - } - } - None // ❌ Fallback to Godot -} - -fn set_property(&mut self, property: StringName, value: Variant) -> bool { - if let Some(env) = &mut self.env { - match env.set_exported_property(&prop_name, fs_value, true) { - Ok(_) => return true, // ✅ We handled it - Err(_) => return false, // ❌ Fallback to Godot - } - } - false // ❌ Fallback to Godot -} -``` - -**Benefits**: - -- Built-in Node2D properties (position, rotation) still work -- No conflicts between FerrisScript and Godot systems -- Clean separation of concerns -- Graceful degradation on errors - -**Evidence**: Can use `node.position` in Inspector alongside `@export` properties - -**Lesson**: **Use Option/bool return types for fallback behavior** - -- `Some(value)` / `true` = "I handled this" -- `None` / `false` = "Let someone else handle this" -- Enables coexistence with existing systems -- Prevents conflicts and confusion - ---- - -#### 4. Context-Aware Behavior with `from_inspector` Parameter ✅ - -**Discovery**: Runtime `set_exported_property()` has `from_inspector: bool` parameter - -**Behavior**: - -- `from_inspector = true` → Apply range clamping (user-friendly) -- `from_inspector = false` → No clamping (full control for scripts) - -**Example**: - -```ferris -@export(range(0, 100)) -let mut health: i32 = 50; - -fn damage(amount: i32) { - health = health - amount; // Can go negative (from_inspector=false) -} -``` - -In Inspector: - -- User sets health to 150 → Clamped to 100 (from_inspector=true) - -In Runtime: - -- `damage(60)` called → health = -10 (from_inspector=false, no clamp) - -**Benefits**: - -- Inspector UX friendly (prevents invalid values) -- Runtime has full control (can exceed limits temporarily) -- Single API serves both use cases - -**Lesson**: **Context-aware parameters enable elegant dual behavior** - -- Identify who's calling (Inspector vs Runtime) -- Adjust behavior appropriately -- One function, multiple UX patterns -- Document both behaviors clearly - ---- - -#### 5. Documentation-First Accelerates Development ✅ - -**Approach**: Write comprehensive doc comments before/during implementation - -**Bundle 7 Example**: 65+ lines of documentation for ~65 lines of code (1:1 ratio!) - -**Doc Structure**: - -```rust -// ========== Phase 5 Sub-Phase 3: Property Hooks (Bundle 7) ========== - -/// Called by Godot Inspector when reading a property value. -/// -/// This enables Inspector to display FerrisScript @export properties. -/// -/// Flow: -/// 1. Inspector needs property value → calls get_property("health") -/// 2. Check if we have runtime storage (script loaded) -/// 3. Query FerrisScript storage: env.get_exported_property("health") -/// 4. Found → convert Value to Variant, return Some(variant) -/// 5. Not found → return None (fallback to Godot) -/// -/// Return Semantics: -/// - Some(value) = "We have this property, here's the value" -/// - None = "Not our property, try Godot's implementation" -/// -/// Example: -/// - "health" → Some(Variant::from(100)) (FerrisScript property) -/// - "position" → None (Node2D built-in, fallback) -fn get_property(&self, property: StringName) -> Option { - // ... implementation -} -``` - -**Benefits**: - -- Implementation writes itself from docs -- Edge cases documented while fresh -- Return semantics crystal clear -- Future maintainers understand quickly -- +15 min writing time, saves hours debugging - -**Evidence**: Bundle 7 Phase 2 completed in 35 minutes with no logic errors - -**Lesson**: **Invest in documentation during implementation** - -- Write flow diagrams in comments -- Document return semantics clearly -- Explain edge cases inline -- Doc-to-code ratio of 1:1 or higher for complex features -- **Time saved debugging > Time spent documenting** - ---- - -#### 6. Single-Line Changes with Massive Impact ✅ - -**Bundle 8**: One line of code, huge workflow improvement - -**Change**: - -```rust -self.base_mut().notify_property_list_changed(); // ⬅️ This one line -``` - -**Impact**: - -- Inspector auto-refreshes on script reload -- Properties update automatically when script modified -- No manual scene reload needed -- Seamless hot-reload experience - -**Result**: 20 minutes implementation time for major UX improvement - -**Lesson**: **Don't underestimate "small" changes** - -- Research where strategic calls go -- One well-placed function call can transform UX -- High-leverage changes exist - find them -- **Impact ≠ Lines of code** - ---- - -#### 7. Pre-Commit Hooks Save Time ✅ - -**Setup**: Pre-commit hooks run formatting, linting, tests - -**Issue During Session**: Forgot to run `cargo fmt` before committing Bundle 7 Phase 2 - -**Hook Caught**: - -``` -✅ Formatting check... -❌ Formatting failed - fixing... -``` - -**Result**: Hook auto-fixed, then accepted commit - -**Time Saved**: ~5 minutes of manual fix + re-commit - -**Lesson**: **Invest in pre-commit hooks early** - -- Format: `cargo fmt` -- Lint: `cargo clippy` -- Quick tests: `cargo test --lib` -- Catches issues before CI -- Saves PR revision cycles - -**Recommendation**: Add to every Rust project Day 1 - ---- - -### 🚧 What Could Be Improved - -#### 1. Doc Comments vs Regular Comments Confusion ⚠️ - -**Issue**: Used `///` (doc comments) for inline explanations in Bundle 8 - -**Error**: - -``` -warning: unused doc comment -note: use `//` for a plain comment -``` - -**Correction**: Changed to `//` regular comments - -**Root Cause**: Unclear distinction between doc comment types - -**Clarification**: - -- `///` (doc comments): Only for function/struct/module documentation -- `//` (regular comments): For inline code explanations -- `//!` (module-level docs): For file/module overview - -**Lesson**: **Understand comment types in Rust** - -```rust -/// This documents the function below ✅ -fn my_function() { - // This explains the logic ✅ - let x = 5; -} - -fn another_function() { - /// This is wrong - nothing below to document ❌ - let y = 10; - - // This is correct ✅ - let y = 10; -} -``` - ---- - -#### 2. rustfmt Pre-Commit Still Requires Manual Run ⚠️ - -**Issue**: Pre-commit hook checks formatting but doesn't auto-fix - -**Workflow**: - -1. Attempt commit → Hook fails -2. Manually run `cargo fmt` -3. Re-attempt commit → Hook passes - -**Better Workflow**: - -```bash -# Pre-commit hook should: -if ! cargo fmt --check; then - echo "❌ Formatting check failed - auto-fixing..." - cargo fmt - echo "✅ Formatting fixed - please review and commit again" - exit 1 # Require manual re-commit to review changes -fi -``` - -**Lesson**: **Pre-commit hooks should be helpful, not just gatekeepers** - -- Check → Fail → Fix → Require review → Pass -- Don't just reject, help fix the issue -- User reviews auto-fixes before committing - ---- - -#### 3. godot_bind Tests Require Godot Engine ⚠️ - -**Issue**: 10 tests fail with "Godot engine not available" - -**Root Cause**: Tests call Godot FFI functions that need engine runtime - -**Current State**: - -- 11 tests pass (type mapping, API structure) -- 10 tests fail (Godot FFI calls) - -**Workaround**: Skip godot_bind tests in CI with `--no-fail-fast` - -**Better Solution**: Headless Godot testing (see TESTING_STRATEGY_PHASE5.md) - -```bash -# Install godot-headless -wget https://downloads.tuxfamily.org/godotengine/4.3/Godot_v4.3-stable_linux_headless.64.zip - -# Run tests with headless runtime -godot --headless --script run_tests.gd -``` - -**Lesson**: **Plan for integration testing environment early** - -- Identify tests that need external runtime -- Set up headless/mock environments -- Don't accept "tests that always fail" as normal - ---- - -### 🎓 Key Technical Insights - -#### 1. `#[class(tool)]` Annotation Critical 🔑 - -**Discovery**: GPT-5 research revealed this annotation - -**Purpose**: Enables Inspector/editor integration in Godot - -**Without**: - -- Property hooks work at runtime only -- Inspector can't read/write properties during editing -- Properties show in list but can't be modified - -**With**: - -- Property hooks work in editor AND runtime -- Inspector fully functional during editing -- Seamless development experience - -**Lesson**: **Research annotation requirements for editor features** - -- Runtime behavior ≠ Editor behavior -- Some features need special annotations -- Test in editor, not just runtime -- GPT-5 caught what Claude 4.5 missed - ---- - -#### 2. Return Semantics Are Critical for Integration 🔑 - -**Pattern**: Return types communicate "who handles this" - -**Examples**: - -- `Option`: `Some` = handled, `None` = fallback -- `bool`: `true` = handled, `false` = fallback -- `Result`: `Ok` = success, `Err` = error (caller handles) - -**Anti-Pattern**: Always return a value, even when you shouldn't - -```rust -// ❌ Bad: Always returns Some, breaks fallback -fn get_property(&self, property: StringName) -> Option { - Some(Variant::nil()) // Wrong! Should return None for fallback -} - -// ✅ Good: None enables fallback -fn get_property(&self, property: StringName) -> Option { - if self.handles(property) { - Some(self.get_value(property)) - } else { - None // Fallback to Godot - } -} -``` - -**Lesson**: **Design return types for integration, not just success/failure** - -- Think about "who handles what" -- Use types to communicate responsibility -- None/false can be just as important as Some/true - ---- - -#### 3. Range Clamping Context-Aware Design 🔑 - -**Insight**: `from_inspector` parameter enables dual behavior - -**Use Cases**: - -1. **Inspector writes**: User-facing, should clamp to prevent confusion -2. **Runtime writes**: Developer-facing, should not clamp (might be intentional) - -**Example Scenario**: - -```ferris -@export(range(0, 100)) -let mut health: i32 = 100; - -fn _process(delta: f32) { - // Temporary overheal power-up - health = 150; // from_inspector=false, no clamp ✅ -} -``` - -If clamped: Power-up wouldn't work! - -**Lesson**: **Context-aware behavior requires identifying the caller** - -- Who's calling: Inspector vs Runtime? -- What's the intent: User correction vs Intentional override? -- Design API to support both use cases -- Single function, multiple behaviors - ---- - -#### 4. Hot-Reload Requires Notification 🔑 - -**Pattern**: Data structure changes must notify observers - -**Example**: - -```rust -// Script reloads with new properties -self.env = Some(new_env); // New property list - -// ❌ Without notification: -// - Inspector still shows old property list -// - User must manually reload scene - -// ✅ With notification: -self.base_mut().notify_property_list_changed(); -// - Inspector automatically refreshes -// - New properties appear immediately -``` - -**Lesson**: **Observer pattern requires explicit notifications** - -- Data change ≠ Automatic UI update -- Call notification methods after state changes -- Don't assume observers poll for changes -- One line of code, huge UX impact - ---- - -### 🎯 Best Practices from Phase 5 - -#### 1. Research Complex APIs Before Implementation - -**Process**: - -1. Identify API uncertainty (e.g., property hooks unclear) -2. Research using multiple AI sources (Claude + GPT) -3. Compare results, note discrepancies -4. Synthesize into unified plan -5. Implement with high confidence - -**Time Investment**: 30 minutes research → saves 2-3 hours trial-and-error - ---- - -#### 2. Implement Risky Features in Phases - -**Pattern**: - -1. **Phase 1**: Verification stub (10 min) - - Minimal implementation - - Validate API usage - - Log to confirm hooks called - - Commit: Early checkpoint - -2. **Phase 2**: Full integration (35 min) - - Replace stubs with real logic - - Add comprehensive documentation - - Full error handling - - Commit: Complete feature - -**Benefits**: Early validation, clear progression, easy rollback - ---- - -#### 3. Document While Implementing, Not After - -**Anti-Pattern**: - -```rust -// ❌ Write code first, document later -fn get_property(&self, property: StringName) -> Option { - // ... 50 lines of complex logic -} -// TODO: Add documentation -``` - -**Best Practice**: - -```rust -// ✅ Document flow before/during implementation -/// Called by Godot Inspector when reading a property value. -/// -/// Flow: -/// 1. Inspector needs value → calls get_property("health") -/// 2. Check runtime storage → env.get_exported_property() -/// 3. Found → return Some(variant) -/// 4. Not found → return None (fallback) -/// -/// Return Semantics: -/// - Some(value) = "We handle this property" -/// - None = "Fallback to Godot" -fn get_property(&self, property: StringName) -> Option { - // Implementation writes itself from docs above -} -``` - -**Benefit**: Implementation writes itself, edge cases documented - ---- - -#### 4. Test Integration, Not Just Units - -**Current Coverage**: - -- ✅ 543 compiler tests (excellent unit coverage) -- ⚠️ 0 integration tests (gap!) - -**Missing**: - -- Compile → Runtime → Inspector sync -- Hot-reload behavior -- Property hook edge cases - -**Recommendation**: See TESTING_STRATEGY_PHASE5.md for comprehensive plan - ---- - -### 📈 Efficiency Metrics - -| Metric | Bundle 5-6 | Bundle 7 | Bundle 8 | Total | -|--------|------------|----------|----------|-------| -| **Estimated Time** | 3-4 hours | 90 min | 30 min | 5.5-6 hours | -| **Actual Time** | ~2 hours | 45 min | 20 min | ~3 hours | -| **Efficiency Gain** | 33-50% | 50% | 33% | ~45% | -| **Key Factor** | Reuse Bundle 1-2 | Phased approach | Simple API | Research investment | -| **Tests Added** | 0 (existing) | 0 (headless needed) | 0 (headless needed) | 0 | -| **Tests Passing** | 543 | 543 | 543 | 543 | -| **Documentation** | 1400+ lines | 533 lines | 25 lines | ~2000 lines | - -**Total Phase 5 Sub-Phase 3**: 1.5 hours vs 2.5 estimated (40% faster) - ---- - -### 🔬 Technical Decisions - -#### 1. Property Hooks Use Fallback Pattern - -**Decision**: `Option` and `bool` return types for coexistence - -**Rationale**: - -- Allows built-in Node2D properties to work -- Clean separation FerrisScript vs Godot -- Graceful degradation on errors - -**Alternative Considered**: Always handle all properties - -- ❌ Would break position, rotation, etc. -- ❌ Conflicts with Godot system -- ❌ No fallback on errors - ---- - -#### 2. Range Clamping Context-Aware - -**Decision**: `from_inspector` parameter controls clamping - -**Rationale**: - -- Inspector: User-facing, should prevent invalid values -- Runtime: Developer-facing, needs full control -- Single API serves both use cases - -**Alternative Considered**: Always clamp - -- ❌ Would break temporary overrides (power-ups, etc.) -- ❌ Too restrictive for gameplay - ---- - -#### 3.
