Debugging in Console

In you have once started IRB or Rails console, you've noticed that a temporary run/debug configuration for consoles has been created, and has appeared in the list of available run/debug configurations.

If necessary, you can save this run/debug configuration as a permanent one.

ruby_irb_console_run_configuration

This run/debug configuration makes it possible to rerun a console, or launch it in debug mode. Moreover, you can also debug source code from the editor immediately in the console.

To debug source code in a console, follow these general steps

  1. On the main toolbar, click the run/debug configuration selector, and choose a temporary or permanent run/debug configuration for console. Refer to the section Running Applications.
  2. With the desired console run/debug configuration selected, click debug.
    ruby_irb_console

    The console starts in debug mode.

  3. Make sure that the class you want to debug is opened in the active editor, and breakpoints are set:
    ruby_irb_console_breakpoint
  4. Do one of the following:
    • On the main menu choose Tools | Load File/Selection into IRB/Rails Console .
    • In the console, type the load command, and press Enter:
      load <file name>
    The whole file from the active editor is loaded into the console.
  5. In the Console tab of the debugger, type the name of the method you want to debug:
    ruby_debugInConsole1

    Breakpoint is hit:

    ruby_irb_console_breakpoint_hit

    Debug tool window shows the Debugger tab:

    ruby_irb_console_debugger
  6. Proceed through the code, using the stepping toolbar buttons. Explore threads, variables, and watches.
