5 " This plugin is intended for quick import-line insertion.
6 " For example you have got "from foo.bar import Baz" import somewhere in
7 " your Git-versioned code. In another file you can write "Baz" and then
8 " press <F3> in insert mode. Completion menu will show you suggestions
9 " of all import lines from your code containing Baz import.
11 " If you have Pylint or Pyflakes output in quickfix window, containing
12 " unfedined variables errors, then you can you :call python#importcompl#all()
13 " function. It will go through the quickfix list and find all possible
14 " imports, sort them and insert under current cursor position.
16 " It uses external "git grep" call and assumes that "canonical" Python
17 " import format is used (single import per line).
18 " You can use http://www.git.stargrave.org/?p=pyimportcan.git;a=blob;f=pyimportcan.pl
19 " utility to convert existing imports to that format.
