Design Decisions (Finalized) + +### 8.1 Code Replacement Strategy +**Status: DECIDED** - See Section 11 for experiment results. + +**Decision: Hybrid Approach (C)** - Tree-sitter for analysis + text-based replacement + +**Tested Approaches**: +- (A) jscodeshift/recast - Requires Node.js, adds complexity +- (B) Text-based - Simple, 100% pass rate on 19 test cases +- (C) Hybrid - Tree-sitter analysis + text replacement, 100% pass rate + +**Why Hybrid**: +- Tree-sitter provides accurate function boundaries for all JS/TS constructs +- Text-based replacement is simple, fast, and handles all edge cases +- No Node.js dependency required +- Syntax validation possible via tree-sitter after replacement + +### 8.2 Return Value Capture +**Decision: Option B** - Instrument test code to capture return values. + +**Implementation**: +- Inject code at the start/end of each test to capture return values +- For return values, prefer sqlite db to store the results. This is similar to the current implementation. +- Parse both JUnit XML (pass/fail, timing) and sqlite for full verification + +### 8.3 TypeScript Handling +**Decision: Option A** - Separate language implementation that extends JavaScript. + +**Implementation**: +```python +class TypeScriptSupport(JavaScriptSupport): + """TypeScript extends JavaScript with type-aware differences.""" + + @property + def name(self) -> str: + return "typescript" + + @property + def file_extensions(self) -> list[str]: + return ['.ts', '.tsx'] + + # Override methods where TypeScript differs from JavaScript + def _get_parser(self): + return TreeSitterAnalyzer('typescript') +``` + +### 8.4 Monorepo Support +**Decision**: Single language per module configuration. + +**Implementation**: +- Each `[tool.codeflash]` section in `pyproject.toml` configures one module +- Language is detected from `module-root` or explicitly specified +- For multi-language monorepos, users run codeflash separately per module + +--- + +## 9. Dependencies + +### Python Dependencies (pyproject.toml) +```toml +[project.dependencies] +tree-sitter = ">=0.21.0" +tree-sitter-python = ">=0.21.0" +tree-sitter-javascript = ">=0.21.0" +tree-sitter-typescript = ">=0.21.0" +``` + +### Node.js Dependencies (for JS/TS projects) +```json +{ + "devDependencies": { + "@codeflash/tracer": "^1.0.0", + "jest-junit": "^16.0.0" + } +} +``` + +--- + +## 10. Success Criteria + +1. **Functional**: Can optimize a JavaScript function end-to-end +2. **Correct**: All existing Python tests pass +3. **Extensible**: Adding a new language requires only implementing `LanguageSupport` +4. **Maintainable**: Core orchestration code has no language-specific logic +5. **Performant**: No significant regression in Python optimization speed + +--- + +## 11. Code Replacement Experiment Results + +**Experiment Date**: 2026-01-14 + +### 11.1 Approaches Tested + +| Approach | Description | Dependencies | +|----------|-------------|--------------| +| **A: jscodeshift** | AST-based via Node.js subprocess | Node.js, npm | +| **B: Text-Based** | Pure Python line manipulation | None | +| **C: Hybrid** | Tree-sitter analysis + text replacement | tree-sitter | + +### 11.2 Test Cases + +19 test cases covering: +- Basic function declarations +- Arrow functions (const, one-liner) +- Class methods and static methods +- Async functions +- TypeScript typed functions and generics +- Functions with JSDoc and inline comments +- Nested functions +- Export patterns (named, default) +- Decorated methods +- Edge cases (first/last/only function in file) +- Deep indentation scenarios + +### 11.3 Results + +| Approach | Passed | Failed | Pass Rate | Total Time | +|----------|--------|--------|-----------|------------| +| **B: Text-Based** | 19 | 0 | **100%** | 0.04ms | +| **C: Hybrid** | 19 | 0 | **100%** | 0.08ms | +| A: jscodeshift | - | - | - | (requires npm setup) | + +### 11.4 Decision + +**Selected Approach: Hybrid (C) with Text-Based Replacement** + +**Rationale**: +1. **Tree-sitter for analysis**: Use tree-sitter to find function boundaries, understand code structure, and validate syntax +2. **Text-based for replacement**: Use simple line-based text manipulation for the actual code replacement +3. **No Node.js dependency**: Entire codeflash CLI stays in Python, no subprocess overhead + +**Implementation Strategy**: +```python +class JavaScriptSupport: + def replace_function(self, file_path, function: FunctionInfo, new_source: str) -> str: + source = file_path.read_text() + + # Tree-sitter provides precise line numbers from discovery phase + # FunctionInfo already has start_line, end_line from tree-sitter analysis + + # Text-based replacement using line numbers + lines = source.splitlines(keepends=True) + before = lines[:function.start_line - 1] + after = lines[function.end_line:] + + # Handle indentation adjustment + new_lines = self._adjust_indentation(new_source, function.start_line, lines) + + return ''.join(before + new_lines + after) +``` + +### 11.5 Key Findings + +1. **Text-based replacement is sufficient**: With accurate line numbers from tree-sitter, simple text manipulation handles all edge cases correctly. + +2. **Tree-sitter adds value for analysis, not transformation**: Tree-sitter is valuable for: + - Finding function boundaries accurately + - Understanding code structure (nested functions, classes) + - Syntax validation of results + - But NOT needed for the replacement itself + +3. **No external dependencies needed**: jscodeshift would require Node.js subprocess calls, adding complexity and latency. The text-based approach works entirely in Python. + +4. **Indentation handling is critical**: The key to correct replacement is: + - Detecting original function's indentation + - Adjusting new function's indentation to match + - Preserving surrounding whitespace + +### 11.6 Experiment Files + +Experiments are located in: `experiments/code_replacement/` +- `test_cases.py` - 19 test cases
