I want to complete a snippet plugin. that works like SnipMate. but I
want it act as cca.vim (you can search these two plugin on vim.org).
it means, I want to detect all changes in user buffer. if user did
some thing that changed the snippets, I will drop the current snippet
complete.
e.g.
user input:
for<tab>
and it changes to:
for (i| = 0; i < len; ++i)
{
/* code here... */
}
| meas cursor. and user press <tab> the cursor jump to "0".
but, if user press <esc>u, i will drop the snippet complete. makes key
<tab> works in a normal way.
