Contributing guide

This page is about contributing to Continuwuity. The development and code style guide pages may be of interest for you as well.

If you would like to work on an issue that is not assigned, preferably ask in the Matrix room first at #continuwuity:continuwuity.org, and comment on it.

Code Style

Please review and follow the code style guide for formatting, linting, naming conventions, and other code standards.

Pre-commit Checks

Continuwuity uses pre-commit hooks to enforce various coding standards and catch common issues before they're committed. These checks include:

Code formatting and linting
Typo detection (both in code and commit messages)
Checking for large files
Ensuring proper line endings and no trailing whitespace
Validating YAML, JSON, and TOML files
Checking for merge conflicts

You can run these checks locally by installing prefligit:

# Requires UV: https://docs.astral.sh/uv/getting-started/installation/
# Mac/linux: curl -LsSf https://astral.sh/uv/install.sh | sh
# Windows: powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

# Install prefligit using cargo-binstall
cargo binstall prefligit

# Install git hooks to run checks automatically
prefligit install

# Run all checks
prefligit --all-files

Alternatively, you can use pre-commit:

# Requires python

# Install pre-commit
pip install pre-commit

# Install the hooks
pre-commit install

# Run all checks manually
pre-commit run --all-files

These same checks are run in CI via the prefligit-checks workflow to ensure consistency. These must pass before the PR is merged.

Running tests locally

Tests, compilation, and linting can be run with standard Cargo commands:

# Run tests
cargo test

# Check compilation
cargo check --workspace

# Run lints
cargo clippy --workspace
# Auto-fix: cargo clippy --workspace --fix --allow-staged;

# Format code (must use nightly)
cargo +nightly fmt

Matrix tests

Continuwuity uses Complement for Matrix protocol compliance testing. Complement tests are run manually by developers, and documentation on how to run these tests locally is currently being developed.

If your changes are done to fix Matrix tests, please note that in your pull request. If more Complement tests start failing from your changes, please review the logs and determine if they're intended or not.

Sytest is currently unsupported.

Writing documentation

Continuwuity's website uses mdbook and is deployed via CI using Cloudflare Pages in the documentation.yml workflow file. All documentation is in the docs/ directory at the top level.

To build the documentation locally:

Install mdbook if you don't have it already:

cargo install mdbook # or cargo binstall, or another method

Build the documentation:
```
mdbook build
```

The output of the mdbook generation is in public/. You can open the HTML files directly in your browser without needing a web server.

Commit Messages

Continuwuity follows the Conventional Commits specification for commit messages. This provides a standardized format that makes the commit history more readable and enables automated tools to generate changelogs.

The basic structure is:

<type>[(optional scope)]: <description>

[optional body]

[optional footer(s)]

The allowed types for commits are:

fix: Bug fixes
feat: New features
docs: Documentation changes
style: Changes that don't affect the meaning of the code (formatting, etc.)
refactor: Code changes that neither fix bugs nor add features
perf: Performance improvements
test: Adding or fixing tests
build: Changes to the build system or dependencies
ci: Changes to CI configuration
chore: Other changes that don't modify source or test files

Examples:

feat: add user authentication
fix(database): resolve connection pooling issue
docs: update installation instructions

The project uses the committed hook to validate commit messages in pre-commit. This ensures all commits follow the conventional format.

Creating pull requests

Please try to keep contributions to the Forgejo Instance. While the mirrors of continuwuity allow for pull/merge requests, there is no guarantee the maintainers will see them in a timely manner. Additionally, please mark WIP or unfinished or incomplete PRs as drafts. This prevents us from having to ping once in a while to double check the status of it, especially when the CI completed successfully and everything so it looks done.

Before submitting a pull request, please ensure:

Your code passes all CI checks (formatting, linting, typo detection, etc.)
Your code follows the code style guide
Your commit messages follow the conventional commits format
Tests are added for new functionality
Documentation is updated if needed

Direct all PRs/MRs to the main branch.

By sending a pull request or patch, you are agreeing that your changes are allowed to be licenced under the Apache-2.0 licence and all of your conduct is in line with the Contributor's Covenant, and continuwuity's Code of Conduct.

Contribution by users who violate either of these code of conducts may not have their contributions accepted. This includes users who have been banned from continuwuity Matrix rooms for Code of Conduct violations.
