"pythoncomplete.vim - Omni Completion for python
|
||||
" Maintainer: Aaron Griffin
|
||||
" Version: 0.3
|
||||
" Last Updated: 23 January 2006
|
||||
"
|
||||
" v0.3 Changes:
|
||||
" added top level def parsing
|
||||
" for safety, call returns are not evaluated
|
||||
" handful of parsing changes
|
||||
" trailing ( and . characters
|
||||
" argument completion on open parens
|
||||
" stop parsing at current line - ++performance, local var resolution
|
||||
"
|
||||
" TODO
|
||||
" RExec subclass
|
||||
" Code cleanup + make class
|
||||
" use internal dict, not globals()
