CONTRIBUTING.md

Contributing

README.md is a generated file. Do not edit it directly. Edit the files inside .README instead.

Pre-Commit Hook

When making a commit, the following Pre-Commit hooks run:

• test and documentation checks
• tests
• lint
• commit message validation (see "Commit Messages" below)

Commit Messages

All commit messages must begin with one of the following prefixes:

• fix:
• feat:
• refactor:
• docs:
• chore:

The prefix is used to bump the correct segment of the version number during the automatic release.

Tests

Run them with npm test.

Lint

Run with npm run lint.

Adding a Rule

Source & Tests

1. Create a file in tests/rules/assertions named the camelCase version of your rule name with the following template:

• export default { invalid: [], valid: [] }

2. Add your test file to tests/rules/index.js
3. Create a file in src/rules named the camelCase version of your rule name
4. Add your rule file to src/index.js

Adding Documentation

1. Create new file in ./.README/rules/[rule-name].md.

• Use ./.README/rules/require-valid-file-annotation.md as a template.
• Ensure that rule documentation document includes <!-- assertions spaceAfterTypeColon --> declaration.

1. Update ./.README/README.md to include the new rule.
2. Run npm run create-readme to generate the new README.md (you must be on master branch for this command to work)

Note: Sections "The following patterns are considered problems:" and "The following patterns are not considered problems:" are generated automatically using the test cases.
