github.dismiss_out_of_range_messages
rubocop.lint inline_comment: true

lint(config: Hash)

Runs Ruby files through Rubocop. Generates a markdown list of warnings.

This method accepts a configuration hash. The following keys are supported:

files: array of file names or glob patterns to determine files to lint
force_exclusion: pass true to pass --force-exclusion argument to Rubocop. (this option will instruct rubocop to ignore the files that your rubocop config ignores, despite the plugin providing the list of files explicitely)
inline_comment: pass true to comment inline of the diffs.
fail_on_inline_comment: pass true to use fail instead of warn on inline comment.
report_danger: pass true to report errors to Danger, and break CI.
config: path to the .rubocop.yml file.
only_report_new_offenses: pass true to only report offenses that are in current user's scope. Note that this won't mark offenses for Metrics/XXXLength if you add lines to an already existing scope.
include_cop_names: Prepends cop names to the output messages. Example: "Layout/EmptyLinesAroundBlockBody: Extra empty line detected at block body end."

Passing files as only argument is also supported for backward compatibility.
