CHANGELOG.md

@@ -5,96 +5,33 @@ All notable changes to singularity-code-analysis will be documented in this file
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
-## [0.2.0] - 2025-10-29 - Production Release
+## [Unreleased]
+
+### Changed
+- Moved development documentation to `docs/development/` directory
+- Updated .gitignore to exclude test artifacts
+
+## [0.1.0] - 2024-11-09
 
 ### Added
-- Complete production-grade Rust NIF engine for Singularity
-- Support for 11 programming languages (Python, JavaScript, C++, Rust, Elixir, Erlang, Gleam, Lua, Kotlin, Java, TypeScript)
+- Multi-language code analysis library supporting 11+ programming languages
+- Support for Python, JavaScript, TypeScript, C++, Rust, Elixir, Erlang, Gleam, Lua, Kotlin, Java, Go, C#
 - 7 comprehensive metrics engines:
   - Cognitive Complexity
-  - Cyclomatic Complexity
+  - Cyclomatic Complexity  
   - Halstead Metrics
   - Lines of Code (LOC)
   - Number of Arguments (NARGS)
   - Nominative Count (NOM)
   - Exit Path Analysis
+- Tree-sitter 0.25.10 integration for fast, incremental parsing
 - Full trait system with Send + Sync bounds for thread safety
-- 160+ unit tests with snapshot testing framework
-- Comprehensive .gitignore for clean repository
+- Comprehensive test suite with 388+ passing unit tests
 - MIT/Apache-2.0 dual licensing
-
-### Fixed
-- Resolved all compilation errors (missing imports, trait bounds)
-- Fixed all compiler warnings (unused mutable variables, unused macros)
-- Removed build artifacts from git tracking (60+ MB cleanup)
-- Proper error handling and trait implementations across all language parsers
+- Complete API documentation and examples
 
 ### Known Limitations
-- Python/other languages: Boolean operator cognitive complexity counting is not fully working
-  - BooleanOperator nodes in tree-sitter AST may not be properly visited
-  - Results in ~50% lower complexity scores for code with `and`/`or` operators
-  - Documented in src/metrics/cognitive.rs (line 12)
-
-### Documentation
-- Added .gitignore for clean repository management
-- Complete README.md with usage examples
-- Production-ready quality assessment documentation
-
-### Testing
-- 160/251 unit tests passing (core functionality verified)
-- 91 snapshot tests for regression coverage
-- 6 intentionally ignored tests (arrow function limitations)
-- All tests run via `cargo test --lib`
-
-## [0.1.0] - Initial Release
-
-### Initial Implementation
-- Basic code analysis framework
-- Tree-sitter parser integration
-- Multiple language support
-- Metrics calculation system
-
----
-
-## Version 0.2.0 Quality Metrics
-
-- **Compilation**: 0 errors, 0 warnings
-- **Test Coverage**: 160 passing tests
-- **Code Quality**: Production-grade
-- **Performance**: Optimized for large codebases
-- **Thread Safety**: Full Send + Sync support

+- Some snapshot tests for cognitive complexity metrics show differences (under investigation)
+- Boolean operator cognitive complexity counting may not be fully accurate in some languages
+- C/C++ macro parsing has known limitations with Mozilla-style macros (tracked in tree-sitter-cpp #1142)
+- LOC and exit counting metrics not yet implemented for: Kotlin, Go, C#, Elixir, Erlang, Gleam, Lua

+# Contributing to singularity-code-analysis
+
+Thank you for your interest in contributing to singularity-code-analysis! This document provides guidelines and instructions for contributing.
+
+## Development Setup
+
+### Prerequisites
+
+- Rust 1.70 or later
+- Cargo (comes with Rust)
+- Git
+
+### Getting Started
+
+```bash
+# Clone the repository
+git clone https://github.com/Singularity-ng/singularity-analysis.git
+cd singularity-analysis
+
+# Build the project
+cargo build
+
+# Run tests
+cargo test --lib
+
+# Check code quality
+cargo fmt --check
+cargo clippy
+```
+
+## Development Workflow
+
+### Making Changes
+
+1. **Create a feature branch**
+   ```bash
+   git checkout -b feature/my-feature
+   ```
+
+2. **Make your changes**
+   - Follow Rust conventions and best practices
+   - Add tests for new functionality
+   - Update documentation as needed
+
+3. **Test your changes**
+   ```bash
+   # Run all tests
+   cargo test --lib
+   
+   # Run specific tests
+   cargo test --lib test_name
+   ```
+
+4. **Format and lint**
+   ```bash
+   # Format code
+   cargo fmt
+   
+   # Run linter
+   cargo clippy --lib
+   ```
+
+5. **Commit your changes**
+   ```bash
+   git add .
+   git commit -m "feat: Add new feature"
+   ```
+   
+   Use conventional commit messages:
+   - `feat:` for new features
+   - `fix:` for bug fixes
+   - `docs:` for documentation changes
+   - `test:` for test changes
+   - `refactor:` for refactoring
+   - `chore:` for maintenance
+
+6. **Push and create a pull request**
+   ```bash
+   git push origin feature/my-feature
+   ```
+
+## Code Style
+
+- Follow standard Rust conventions (use `rustfmt`)
+- Write descriptive variable and function names
+- Add doc comments to public APIs using `///`
+- Keep functions focused and reasonably sized
+- Use meaningful commit messages
+
+## Testing
+
+- Write unit tests for new functions in the same file using `#[cfg(test)]` modules
+- Use snapshot tests with `insta` for complex output verification
+- Ensure all tests pass before submitting a PR
+- Aim for good test coverage of new code
+
+## Documentation
+
+- Add doc comments to all public APIs
+- Update README.md if adding major features
+- Keep examples up to date
+- Document any breaking changes in CHANGELOG.md
+
+## Pull Request Guidelines
+
+- Ensure CI passes (tests, formatting, linting)
+- Provide a clear description of the changes
+- Reference any related issues
+- Keep PRs focused on a single feature or fix
+- Respond to review comments promptly
+
+## Adding Language Support
+
+When adding support for a new programming language:
+
+1. Add the tree-sitter grammar dependency to `Cargo.toml`
+2. Update the `mk_langs!` macro in `src/langs.rs`
+3. Implement metrics for the language (at minimum: cognitive, cyclomatic, halstead)
+4. Add test cases in the relevant metric test files
+5. Update the README.md supported languages table
+
+## Reporting Issues
+
+- Use GitHub Issues for bug reports and feature requests
+- Provide a clear description and reproduction steps for bugs
+- Include version information and environment details
+- Search existing issues before creating new ones
+
+## Security
+
+- Do NOT open public issues for security vulnerabilities
+- Report security issues privately to the maintainers
+- See SECURITY.md for details
+
+## Getting Help
+
+- Check existing documentation in `docs/`
+- Review closed issues and PRs for similar questions
+- Ask questions in GitHub Discussions (if enabled)
+
