In this section:


When a breakpoint is reached the Debug tool window becomes active and enables you to get control over the program's execution. For this purpose, you can use the Run menu commands, or the icons on the stepping toolbar of in the Debug tool window.

Each stepping action advances the execution point to the next execution location, depending on the action you choose.

Stepping through the program

Do one of the following:

Suppressing stepping into

You can create a list of scripts that you want the debugger skip while stepping through the program.

  1. Open the Settings / Preferences Dialog by pressing Ctrl+Alt+S or by choosing File | Settings for Windows and Linux or WebStorm | Preferences for OS X. Expand the Buld, Execution, Deployment node, and then click page_name under Debugger.
  2. On the Stepping page that opens:
    • To have the debugger skip all library scripts, select the Do now step into library scripts check box.
    • To suppress stepping into some specific scripts, select the Do not step into scripts check box and create a list of such scripts using the toolbar buttons.

Tips and tricks

  • The Force Step Into command frames_step_into enables you to step into a method of a class not to be stepped into .
    The classes, stepping into which is suppressed, are specified on the Stepping page of the Settings/Preferences dialog box.
  • The Force Step Over command force_step_over enables you to jump over the method call ignoring the breakpoints on the way.
  • The Force Run to Cursor command frames_run_to_cursor enables you to jump to the cursor position ignoring existing breakpoints on the way.
