Autocompleting Python Modules
Simplifying the search for modules to execute from a shell.
The last few times I overhauled an execution environment I required people to execute the bulk of their tools via
python -m package.module instead of
python package/module.py (to enable the development environment).
The downside is that you lose shell autocompletion, which can be a big deal if you have dozens of tools that you only occasionally use.
This addition to your
~/.bashrc fixes that.
Essentially, it walks
sys.path (or the
__path__ of the most specific package given) looking for modules that match. Packages are only listed if a
__main__ module exist within them.
wsgi completes to
wsgiref., and then:
$ python -m wsgiref. wsgiref.handlers wsgiref.headers wsgiref.simple_server wsgiref.util wsgiref.validate
Warning: This does import the most specific package given (e.g. autocompleting
email.mime will import it, and therefore may have side effects).
