Important notes

  • IRB and/or Rails consoles appear in the separate tabs of the Run tool window every time you choose the corresponding command on the Tools menu.
  • An interactive console is divided into two panes: the lower pane serves for user input, the upper pane displays results and messages.
  • Rails console is only available for the Rails applications.
    IRB is available for both pure Ruby projects, and Rails applications.
  • Use up and down arrow keys to browse through the history of executed commands, and repeat the desired ones.
  • Color and font scheme of a console is configurable on the Console Colors and Console Fonts pages of the Color Scheme editor settings.

Clicking the button once invokes soft kill allowing the application to catch the SIGINT event and perform graceful termination (on Windows, the Ctrl+C event is emulated). After the button is clicked once, it is replaced with icon run tool window kill indicating that subsequent click will lead to force termination of the application, e.g. on Unix SIGKILL is sent.
