**neocomplcache**
=================

Note:  It is not maintained well.  You should use Deoplete instead.

Description
-----------

neocomplcache is the abbreviation of "neo-completion with cache". It
provides keyword completion system by maintaining a cache of keywords in the
current buffer. neocomplcache could be customized easily and has a lot more
features than the Vim's standard completion feature.

If you use Vim 7.3.885 or above with if\_lua feature, you should use
neocomplete.  It is faster than neocomplcache.

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 split from Ver.7.
If you used it, please install neosnippet source manually.
