Behind the scenes

How are identified applicable files

  • Activated only if one of these files is found: .ls-lint.yml
  • If this linter is active, all files will always be linted

How the linting is performed

ls-lint is called once on the whole project directory (project CLI lint mode)

  • filtering can not be done using MegaLinter configuration variables,it must be done using ls-lint configuration or ignore file (if existing)
  • VALIDATE_ALL_CODEBASE: false doesn't make ls-lint analyze only updated files

Example calls

ls-lint

ls-lint --workdir src
