I’m working on a Python script, in PyDev, which will be invoked from the command line. In that environment, shell expansion will be applied to the argument list, which is what I need.

I’m building a Python debugging extension and I’d like it to work with Pydevd. It’d be useful to be able to add a callback which is called just before the main program is paused and control handed to the debugger, and called just before resume when the program is resumed. Is there a callback interface to allow this, or what approach is suggested?
