ruby rubocop in Code Market Place

exec on save


This extension may have a problem when using a rvm or chruby environment. We recommend vscode-ruby. It can also lint ruby code.

When autoCorrect, History of changing file is broken.


  • lint by execute command "Ruby: lint by rubocop" (cmd+shift+p and type command)
  • auto invoke when saving file
  • auto correct command "Ruby: autocorrect by rubocop"

Exclude file

An extension forces rubocop's force-exclusion option.

If you want not to execute rubocop on some file, You could add AllCops/Exclude on rubocop.yml. This can saving without executing rubocop.


Installation of ruby and rubocop is required.

gem install rubocop
  • Type F1 (or Command + Shift + P)
  • execute "Extensions: install extension"
  • type rubocop and execute ext install ruby-rubocop




Specify configuration (via navigating to File > Preferences > Workspace Settings and editing file settings.json):

  // If not specified searches for 'rubocop' executable available on PATH (default and recommended)
  "ruby.rubocop.executePath": "",

  // You can use specific path
  // "ruby.rubocop.executePath": "/Users/you/.rbenv/shims/"
  // "ruby.rubocop.executePath": "/Users/you/.rvm/gems/ruby-2.3.2/bin/"
  // "ruby.rubocop.executePath": "D:/bin/Ruby22-x64/bin/"

  // If not specified, it assumes a null value by default.
  "ruby.rubocop.configFilePath": "/path/to/config/.rubocop.yml",

  // default true
  "ruby.rubocop.onSave": true


You can change keybinding (via editing keybindings.json)

{ "key": "ctrl+alt+l",          "command": "ruby.rubocopAutocorrect",
                                "when": "editorLangId == 'ruby'" }


  • more configurable command line option (like -R)
  • integration with rbenv
