Danger Rubocop

A Danger plugin for Rubocop (and compatible wrappers such as Standard).

Installation

Add this line to your Gemfile:

gem 'danger-rubocop'

Usage

Run Ruby files through Rubocop. Results are passed out as a table in markdown.

Specifying custom config file.

rubocop.lint

Lint specific files in a folder, when they change

public_files = (git.modified_files + git.added_files).select { |path| path.include?("/public/") }
rubocop.lint public_files

Submit comments only for changed lines

github.dismiss_out_of_range_messages
rubocop.lint inline_comment: true

Format using standardrb instead of Rubocop

rubocop.lint rubocop_cmd: 'standardrb'

Methods

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. If omitted, this will lint only the files changed in the pull request. To lint all files every time, pass an empty string; this is the equivalent of typing rubocop without specifying any files, and will follow the rules in your .rubocop.yml.
  • 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 explicitly)
  • inline_comment: pass true to comment inline of the diffs.
  • group_inline_comments: pass true to group inline comments to be a single comment on each line with all issues for that line.
  • fail_on_inline_comment: pass true to use fail instead of warn on inline comment.
  • report_severity: pass true to use fail or warn based on Rubocop severity.
  • report_danger: pass true to report errors to Danger, and break CI.
  • include_cop_names: pass true to include cop names when reporting errors with report_danger.
  • 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."
  • rubocop_cmd: Allows you to change the rubocop executable that's invoked. This is used to support rubocop wrappers like Standard by passing standardrb as the value.
  • skip_bundle_exec: When there is a Gemfile in the project, Rubocop will be executed using Bundler. When true, this flag will force Rubocop to run without bundle exec.

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