General Help

If you are calling the ODB from the command line, there are three primary options which are defined as aliases (UNIX) or .bat files (WINDOWS):

  • debug <program> [args...]: Run the specified <program> with <args...> and bring up the debugger when main() exits.
  • debugp <program> [args...]: Bring up the command window to select options, then run the specified <program> with <args...>.
  • debugn <program> [args...]: Run the specified <program> with <args...> but don't bring up the debugger until STOP RECORDING is pressed. (for multithreaded programs where main() exits early)

The arrow buttons all the execute First/Previous/Next/Last on the selected element. They all have tool-tip popups.

  • Selecting a line in the Trace pane reverts to the first line in that method.
  • Selecting a line in the Threads pane reverts to the nearest previous event in that thread.

  • Selecting a line in the Code pane reverts to AN event on that line (if any). It attempts to revert the most 'reasonable' event, but this is not always clear.

  • Double-clicking on an object anywhere will copy that object into the Objects pane and open it.

  • Double-clicking on an object in the Objects pane will show/not-show the instance variables it.
  • Double-clicking on an instance variable in the Objects pane will show its IVs recursively.

The minibuffer at the bottom of the debugger window will display details about the most recent command. This is also where extended commands such as Incremental String Search and Evaluate Expression are run. For details, see the manual in jar file.
