	# Regarding `--whole-files`, the linter is supposed to support linting of changed a patch only but,
	# for some reason, it's very unreliable this way - sometimes it does not report any or some
	# issues without linting the whole files, so we have to use `--whole-files`
	# which can lead to some frustration from developers who would like to
	# fix a single line in an existing codebase and the linter would force them
	# into fixing all linting issues in the whole file instead.
	args: --timeout=30m --whole-files

	# Optional: show only new issues if it's a pull request. The default value is `false`.
