mozdebug — Configure and launch compatible debuggers.

This module contains a set of function to gather information about the debugging capabilities of the platform. It allows to look for a specific debugger or to query the system for a compatible/default debugger.

The following simple example looks for the default debugger on the current platform and launches a debugger process with the correct debugger-specific arguments:

import mozdebug

debugger = mozdebug.get_default_debugger_name()
debuggerInfo = mozdebug.get_debugger_info(debugger)

debuggeePath = "toDebug"

processArgs = [self.debuggerInfo.path] + self.debuggerInfo.args

run_process(args, ...)
mozdebug.get_debugger_info(debugger, debuggerArgs=None, debuggerInteractive=False)

Get the information about the requested debugger.

Returns a dictionary containing the |path| of the debugger executable, if it will run in |interactive| mode, its arguments and whether it needs to escape arguments it passes to the debugged program (|requiresEscapedArgs|). If the debugger cannot be found in the system, returns |None|.

  • debugger – The name of the debugger.

  • debuggerArgs – If specified, it’s the arguments to pass to the debugger,

as a string. Any debugger-specific separator arguments are appended after these arguments. :param debuggerInteractive: If specified, forces the debugger to be interactive.


Get the debugger name for the default debugger on current platform.


search – If specified, stops looking for the debugger if the default one is not found (|DebuggerSearch.OnlyFirst|) or keeps looking for other compatible debuggers (|DebuggerSearch.KeepLooking|).
