3 Python dot expression completion using Pymacs.
4
5 This almost certainly needs work, but if you add
6
7 (require 'pycomplete)
8
9 to your .xemacs/init.el file (untried w/ GNU Emacs so far) and have Pymacs
10 installed, when you hit M-TAB it will try to complete the dot expression
11 before point. For example, given this import at the top of the file:
12
13 import time
14
15 typing "time.cl" then hitting M-TAB should complete "time.clock".
16
17 This is unlikely to be done the way Emacs completion ought to be done, but
18 it's a start. Perhaps someone with more Emacs mojo can take this stuff and
19 do it right.
20
21 See pycomplete.el for the Emacs Lisp side of things.
