Contributing Guideline

In order to be able to contribute, it is important that you understand the project layout. This project uses the src layout, which means that the package code is located at ./src/irx.

For my information, check the official documentation: https://packaging.python.org/en/latest/discussions/src-layout-vs-flat-layout/

In addition, you should know that to build our package we use Poetry, it's a Python package management tool that simplifies the process of building and publishing Python packages. It allows us to easily manage dependencies, virtual environments and package versions. Poetry also includes features such as dependency resolution, lock files and publishing to PyPI. Overall, Poetry streamlines the process of managing Python packages, making it easier for us to create and share our code with others.

Contributions are welcome, and they are greatly appreciated! Every little bit helps, and credit will always be given.

You can contribute in many ways:

Types of Contributions

Report Bugs

Report bugs at https://github.com/arxlang/irx/issues.

If you are reporting a bug, please include:

  • Your operating system name and version.
  • Any details about your local setup that might be helpful in troubleshooting.
  • Detailed steps to reproduce the bug.

Fix Bugs

Look through the GitHub issues for bugs. Anything tagged with "bug" and "help wanted" is open to whoever wants to implement it.

Implement Features

Look through the GitHub issues for features. Anything tagged with "enhancement" and "help wanted" is open to whoever wants to implement it.

Write Documentation

IRx could always use more documentation, whether as part of the official IRx docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at https://github.com/arxlang/irx/issues.

If you are proposing a feature:

  • Explain in detail how it would work.
  • Keep the scope as narrow as possible, to make it easier to implement.
  • Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!

Ready to contribute? Here’s how to set up irx for local development.

  1. Fork the irx repo on GitHub.
  2. Clone your fork locally:

    $ git clone git@github.com:your_name_here/irx.git
    $ cd irx/
    
  3. Create a new virtual environment and install your local copy into that:

    # note: you can use mamba or conda or micromamba
    $ mamba env create --file conda/dev.yaml
    $ conda activate irx
    $ poetry install
    
  4. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature
    # Now you can make your changes locally.
    
  5. When you’re done making changes, check that your changes pass the linter and the tests:

    $ makim tests.linter
    $ makim tests.unittest
    

    If you need to bootstrap the repository's Codex configuration, run:

    $ makim llm-config.codex
    

    This task clones https://github.com/arxlang/llm-config into ./.tmp/llm-config, copies the cloned .codex directory into the repository root, and removes the temporary clone when it finishes. The reusable llm-config.setup and llm-config.cleanup tasks are available as Makim hooks for future LLM config tasks.

Runtime Type Checking

IRx keeps runtime type checking on by default for its own code under src/irx.

  • Use irx.typecheck.typechecked on every module-level function and every concrete class.
  • Methods are expected to be covered through the class decorator; avoid adding per-method decorators unless the class itself cannot be decorated.
  • Keep @public or @private outermost and place @typechecked on the implementation boundary; for wrappers like @lru_cache(...), that means keeping @typechecked closest to the original function.
  • Keep class decorators ordered as @public or @private, then @typechecked, then @dataclass(...).
  • Write Douki docstrings for private helpers too. Underscore-prefixed functions, methods, and other internal implementation helpers should still have repository-style docstrings unless they are a clearly documented exemption such as a typing-only stub.
  • If you need an exemption for a Protocol or a typing-only stub, document it clearly and update tests/test_typechecked_policy.py in the same change.

Code Style And Architecture

When contributing to IRx, prefer a small set of architectural habits that keep the codebase easier to evolve:

  • Do not define classes inside if TYPE_CHECKING: blocks. Prefer top-level Protocol definitions, aliases, or other patterns that keep typing helpers out of the runtime MRO without hiding class definitions behind conditional blocks.
  • Apply SOLID principles when they improve the design and keep the change practical.
  • Prefer a "never nesting" style when possible: use guard clauses, early returns, and extracted helpers to keep control flow flat and readable.
  • Keep test function names short and descriptive. Prefer a concise test name plus a clear docstring over one long function name that tries to spell out the entire scenario.
  • Avoid literal numbers in assertions when the number is part of the expected behavior. Assign the expected value to a local variable first so the assertion documents intent without relying on magic numbers.

  • Commit your changes and push your branch to GitHub:

    $ git add .
    $ git commit -m "Your detailed description of your changes."
    $ git push origin name-of-your-bugfix-or-feature
    
  • Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests.
  2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in README.rst.
  3. The pull request should work for Python >= 3.8.

Tips

To run a subset of tests, you can use something like:

$ pytest tests.test_binary_op

or

$ makim tests.unittest --path "tests/test_binary_op" --params "-k mytest_func"

Release

This project uses semantic-release in order to cut a new release based on the commit-message.

Commit message format

semantic-release uses the commit messages to determine the consumer impact of changes in the codebase. Following formalized conventions for commit messages, semantic-release automatically determines the next semantic version number, generates a changelog and publishes the release.

By default, semantic-release uses Angular Commit Message Conventions. The commit message format can be changed with the preset or config options_ of the @semantic-release/commit-analyzer and @semantic-release/release-notes-generator plugins.

Tools such as commitizen or commitlint can be used to help contributors and enforce valid commit messages.

The table below shows which commit message gets you which release type when semantic-release runs (using the default configuration):

Commit message Release type
fix(pencil): stop graphite breaking when pressure is applied Fix Release
feat(pencil): add 'graphiteWidth' option Feature Release
perf(pencil): remove graphiteWidth option Chore
feat(pencil)!: The graphiteWidth option has been removed Breaking Release

NOTE: Breaking change's commit message prefix should have ! before :. Also, ensure to specify feat or fix in the prefix.

This project uses the squash and merge strategy, so ensure to apply the commit message format to the PR's title.
