Contributing

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/arx/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

arx could always use more documentation, whether as part of the official arx 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/arx/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 arx for local development.

  1. Fork the arx repo on GitHub.

  2. Clone your fork locally:

$ git clone [email protected]:your_name_here/arx.git
  1. Prepare your local development environment:
$ mamba env create --file /conda/dev.yaml
$ conda activate arx
$ pre-commit install
  1. Create a branch for local development:
$ git checkout -b name-of-your-bugfix-or-feature

Now you can make your changes locally.

  1. When you’re done making changes, check the compilation and the tests:
$ makim build.dev
$ makim tests.all
$ pre-commit run --all-files

Note: if you want to remove all the build folder before starting to build you can run makim build.dev --clean.

  1. 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
  1. 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.md.

Containers

If you want to play with Arx inside a container, there is docker-compose file and a Dockerfile prepared for that.

First, create the conda environment using the following command:

$ mamba env create --file conda/containers.yaml

And activate the new environment:

$ conda activate arx-containers

Now, you can build and run the new container for playing with arx: commands:

containers-sugar build
containers-sugar run

Inside the container you can run the same makim targets, for example:

makim build.dev --clean

Note: For development, remember to install pre-commit hooks:

$ pre-commit install

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
BREAKING CHANGE: The graphiteWidth option has been removed Breaking Release

source: https://github.com/semantic-release/semantic-release/blob/master/README.md#commit-message-format

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