🐞 Workflow for bug reports, feature requests and documentation improvements

Before opening an issue, please search existing issues to avoid duplicates. If an issue exists, you can add a comment with additional details and/or upvote (👍) the issue. If there is not an existing issue, please open one and provide as much detail as possible.

• For feature requests or documentation improvements, please describe your suggestion clearly.
• For bugs, include:
  • Steps to reproduce.
  • Expected and actual behaviour.
  • Environment details (operating system, python version, dependencies).
  • Relevant files (e.g. problematic .qmd files).

Handling bug reports (for maintainers):

• Confirm reproducibility by following the reported steps.
• Label the issue appropriately (e.g. bug).
• Request additional information if necessary.
• Link related issues or pull requests.
• Once resolved, close the issue with a brief summary of the fix.

🚀 Workflow for code contributions (bug fixes, enhancements)

1. Fork the repository and clone your fork.

2. Create a new branch for your feature or fix:

git checkout -b my-feature

3. Make your changes and commit them with clear, descriptive messages using the conventional commits standard.

4. Push your branch to your fork:

git push origin my-feature

5. Open a pull request against the main branch. Describe your changes and reference any related issues.

🛠️ Development and testing

Dependencies

If you want to contribute to lintquarto or run its tests, you’ll need some additional tools:

Tool	Purpose
check-dependencies	Test for undeclared dependencies
flit	Packaging and publishing
genbadge	Create coverage badge (README)
grayskull	Uploading to conda-forge
jupyter	Run python code in docs
pytest	Run tests
pytest-cov	Calculate coverage
twine	Upload to PyPI
types-toml	Required by mypy
quartodoc	Generate API docs
-e .[all]	Editable install + all linters

These are listed in requirements-dev.txt for convenience. To set up your development environment, create an environment (e.g. virtualenv) and run:

pip install -r requirements-dev.txt

For testing only (used by GitHub actions):

pip install -r requirements-test.txt

You can also install the packages in requirements-dev.txt when you install lintquarto by running:

pip install lintquarto[dev]

Quarto (used for the docs) is a standalone tool - install it from https://quarto.org/docs/get-started/.

Dependency versions

Contributors are encouraged to install and use the latest versions of development tools. This helps keep the project compatible with current tooling and catches issues early.

If you need a fully reproducible and stable setup, use the provided Conda environment file. This file pins all development tool versions, including Python:

conda env create -f requirements-stable.yml

To update the stable environment, run conda update --all and test thoroughly (running tests, building documentation), and then update requirements-stable.yml with any changes.

Docstrings

We follow the numpydoc style for docstrings, and check these using pydoclint.

Tests

Run all tests (with coverage):

pytest --cov

Run an individual test file:

pytest tests/test_back.py

Run a specific test:

pytest tests/test_linters.py::test_supported_error

Linting

Make scripts executable (first time only):

chmod +x lint_package.sh
chmod +x lint_docs.sh

Lint the package:

lint_package.sh

Lint the documentation:

lint_docs.sh

Documentation

Build and preview the documentation locally:

make -C docs

When running this, function documentation will be automatically generated from the codebase using quartodoc

📦 Updating the package

Preparation

Before proceeding, you will need to have cloned the lintquarto/staged-recipes repository which is used to push updates to conda.

git clone https://github.com/lintquarto/staged-recipes

Workflow for updates

If you are a maintainer and need to publish a new release:

1. Update the CHANGELOG.md.

2. Update the version number in __init__.py, CITATION.cff and README.md citation, and update the date in CITATION.cff.

3. Create a release on GitHub, which will automatically archive to Zenodo.

4. Build and publish using flit or twine.

To upload to PyPI using flit:

flit publish

To upload to PyPI using twine: remove any existing builds, then build the package locally and push with twine, entering the API token when prompted:

rm -rf dist/
flit build
twine upload --repository pypi dist/*

For test runs, you can use the same method with test PyPI:

rm -rf dist/
flit build
twine upload --repository testpypi dist/*

5. If you haven’t already, fork the lintquarto feedstock (conda-forge/lintquarto-feedstock). This fork must be to your personal GitHub account and not an organisation account. Clone it to your local machine.

If you already have a fork, make sure it is up-to-date by running git pull.

6. Create and checkout a branch - e.g. update_0_5_0.

git checkout -b update_0_5_0

7. Use grayskull to update the recipe (recipe/meta.yaml). It will pull the metadata about the package from PyPI, and will not use your local installation of the package.

grayskull pypi lintquarto

It will create lintquarto/meta.yaml. You will need to copy over the contents into recipe/meta.yaml. When you do so, make sure to keep the two fixes made to the meta.yaml file which are…

Fix A: The addition of a home element within about.

home: https://lintquarto.github.io/lintquarto/

Fix B: Correct python version requirements syntax as per the conda-forge documentation, using python_min for host (fixed version), run (minimum version) and requires (fixed version).

Note: Don’t need to set the python_min anywhere unless it differs from conda default (currently 3.7).

  host:
    - python {{ python_min }}

...

  run:
    - python >={{ python_min }}

...

  requires:
    - python {{ python_min }}

7. Create a commit with the updated feedstock - for example:

git add --all
git commit -m "updated feedstock to version 0.5.0"
git push

8. Use the GitHub website to open a pull request. Completed the provided checklist -

• Personal account? Yes, if you used your GitHub and not an organisation.
• Bump? Not relevant as doing a version update, can remove.
• Reset base? Yes, should show as base: 0 in meta.yaml by default.
• Re-render? Add the command @conda-forge-admin, please rerender to the end of the pull request.

9. Wait for the CI actions to run. If all pass, then you can click “Merge pull request”.
