Tagging installed Python libraries

Generating TAGS for the project I'm working on with the addition of an installed library - Twisted for example - can be a pain:

$ python >>> import twisted >>> twisted.__file__ '/usr/lib/python2.6/dist-packages/twisted/__init__.pyc' >>> $ etags -R src /usr/lib/python2.6/dist-packages/twisted

I got bored of that.

Enter pyctags to take the pain away:

$ pyctags -e -R src py:twisted

It's a pretty simple script:

#!/usr/bin/env python from imp import find_module from os import execvp from os.path import dirname from sys import argv, stderr def expand(arg): if arg.startswith("py:"): module_name = arg[3:].replace(".", "/") try: return find_module(module_name)[1] except ImportError: stderr.write("Could not expand %r.\n" % module_name) return arg else: return arg if __name__ == '__main__': args = ["ctags"] args.extend(expand(arg) for arg in argv[1:]) execvp("ctags", args)
