Code of Conduct

This project follows the Contributor Covenant v2.1. By participating, you are expected to uphold this code.

Getting Started

  1. Fork the repository: https://github.com/swadhinbiswas/contexa
  2. Clone your fork:
    git clone https://github.com/<your-username>/contexa.git
cd contexa
  3. Create a feature branch:
    git checkout -b feat/my-change
  4. Make your changes, add tests, and ensure all tests pass.
  5. Push and open a pull request against main.

Development Setup

Each language lives in its own top-level directory. You only need to install tooling for the language(s) you are working on.

Python (PYTHON/)

  • Requires: Python 3.10+ and uv
  • Setup:
    cd PYTHON
uv sync

JavaScript / TypeScript (JS/)

  • Requires: Node.js 18+ and npm
  • Setup:
    cd JS
npm install

Rust (RUST/)

  • Requires: Rust 1.70+ (stable toolchain)
  • Setup:
    cd RUST
cargo build

Go (GO/)

  • Requires: Go 1.21+
  • Setup:
    cd GO
go mod download

Zig (ZIG/)

  • Requires: Zig 0.14.0 (latest stable)
  • Setup: No package manager needed; zig build handles everything.

Lua (LUA/)

  • Requires: Lua 5.3+ (5.4 recommended)
  • Setup: No package manager needed for development. LuaRocks is only needed for publishing.

Elixir (ELIXIR/)

  • Requires: Elixir 1.15+ and Erlang/OTP 26+
  • Setup:
    cd ELIXIR
mix deps.get

Running Tests

Run the tests for the language(s) you modified before submitting a PR.

Language Command
Python cd PYTHON && uv run pytest -v
JavaScript cd JS && npm test
Rust cd RUST && cargo test
Go cd GO && go test ./...
Zig cd ZIG && zig build test
Lua cd LUA && lua test.lua
Elixir cd ELIXIR && mix test

CI runs all 7 language test suites on every pull request. Your PR must pass all checks before it can be merged.

Submitting Changes

  1. One concern per PR. Keep pull requests focused on a single change.
  2. Write tests. If you add a feature or fix a bug, add or update the relevant tests.
  3. Update docs. If you change the public API surface, update the language-specific README.md.
  4. Fill out the PR template. Check the affected languages and ensure the checklist is complete.
  5. Keep commits clean. Use clear, descriptive commit messages. Squash fixup commits before requesting review.

Branch Naming Convention

  • feat/<description> — new features
  • fix/<description> — bug fixes
  • docs/<description> — documentation changes
  • ci/<description> — CI/build changes
  • refactor/<description> — code refactoring

Code Style

  • Python: Follow PEP 8. The project uses ruff for linting.
  • JavaScript/TypeScript: Follow the existing style. Build with tsup.
  • Rust: Run cargo fmt and cargo clippy before committing.
  • Go: Run gofmt and go vet.
  • Zig: Follow the Zig style guide.
  • Lua: Follow the existing style in LUA/contexa/.
