Enabling Code Completion in an embedded Python Interpreter

Question

I have got a PyQT widget interpreter working, the code picked up from here is as follows:

import os
import re
import sys
import code

from PyQt4.QtGui impo

If you want to save yourself some time - take a look at spyderlib, it contains a widget that embeds an interactive Python interpreter with some interaction sugar such as code completion. The bits of specific interest are

• spyderlib/widgets/sourcecode/codeeditor.py
• spyderlib/shell.py
• spyderlib/editor.py
• spyderlib/widgets/externalshell/pythonshell.py
• spyderlib/utiils/module_completion.py
• spyderlib/plugins/externalconsole.py
• spyderlib/plugins/console.py
• spyderlib/plugins/editor.py

The only caveat I have with spyderlib is that you can't just use that doodad on it's own - somewhere I have a version I extracted that contains the bare minimum of support modules needed to run. If you run into the same problem I did regarding the bloat send me a msg and I'll check my stuff into github for you to grab.

I also seem to remember there's an Qt based interactive Python interpreter widget that is used in NumPy or SciPy - I think it originally came from the ipython project however. It's pretty nice because it actually splits the interpeter from the execution of code - so if your code crashes, your interpreter doesn't crash with it. But, in that case you can't modify the Pythonic contents of other threads.. The spyderlib version can work both ways.
