neocomplcache

Description

Neocomplcache performs keyword completion by making a cache of keywords in a buffer. I implemented it because unlike the Vim builtin keyword completion, neocomplcache can be customized flexibly. Unfortunately, neocomplcache may use more memory than other plugins.

Installation

Extract the file and put files in your Vim directory (usually ~/.vim/ or Program Files/Vim/vimfiles on Windows).
Execute |:NeoComplCacheEnable| command or let g:neocomplcache_enable_at_startup = 1 in your .vimrc. Not in .gvimrc(_gvimrc)!

Caution

Because all variable names were changed in neocomplcache Ver.5, it is not backwards compatible. If you want to upgrade, you should use the following script from Mr.thinca.

Snippets feature(snippets_complete source) was splitted from Ver.7. If you used it, please install snippets_complete source manually.
