" This file demonstrates
|
|
" - how to register your own snippet sources (call snipMate_python_demo#Activate() in ftplugin/python.vim)
|
|
" - implents a source which creates snippets based on python function
|
|
" definitions found in the current file
|
|
"
|
|
" Example:
|
|
"
|
|
" def abc(a,b,c=None)
|
|
" will create a snippet on the fly which looks like this:
|
|
" abc(${1:a}, ${2:b}, ${3:c=None})
