autolesshint uses Gulp to automate building, which requires Node.js.

To build from scratch, install NodeJS and run the following commands:

npm install -g gulp
npm install
gulp

automutate manages the runtime of taking in lint complaints from lesshint. These are mapped to Suggester classes in src/suggesters by name.

automutate-tests manages development-time tests verifying actual file mutations.

Adding a suggester

• Add a Suggester class with a linter's name. my_rule would be mapped to src/suggesters/myRuleSuggester.ts that would have to export a MyRuleSuggester class that implements the ISuggester interface.
• Add test case(s) under test/cases that each have an original.less, expected.less, actual.less, and .lesshintrc.
• Add the suggester to the list in README.md.
• Submit a PR referencing the issue corresponding to the lint rule.
