Python Module Reloading and ReCompiling for Maya

mkDevTools.py

from os import path
import compileall
import sys, types


def recompile(modulename):
    """Recompile the given module, its directory's contents!"""
    myScriptPath = sys.modules[modulename.__name__].__path__[0]
    if path.isdir(myScriptPath):
        compileall.compile_dir(myScriptPath, force=True)


def reload_module(modulename):
    """Reload the given module and all children"""
 
    # Get a reference to each loaded module
    loaded_modules = dict([(key, value) for key, value in sys.modules.items() 
        if key.startswith(modulename.__name__) and 
        isinstance(value, types.ModuleType)])
 
    # Delete references to these loaded modules from sys.modules
    for key in loaded_modules:
        del sys.modules[key]
 
    # Load each of the modules again
    # Make old modules share state with new modules
    for key in loaded_modules:
        print 're-loading %s' % key
        newmodule = __import__(key)
        oldmodule = loaded_modules[key]
        oldmodule.__dict__.clear()
        oldmodule.__dict__.update(newmodule.__dict__)

    recompile(modulename)
    reload_module(modulename)

Thank you so much, It is very usefull for me.

You are welcome, been a while since I got anyone thanking me. Almost forgot I had this gist up.
