neocomplete

Note: Active development on neocomplete.vim has stopped. The only future
changes will be bug fixes.

Please see Deoplete.nvim.

neocomplete is the abbreviation of "neo-completion with cache". It provides
keyword completion system by maintaining a cache of keywords in the current

   Vim's built-in completion.

Note: If you use neovim or Vim8+, you should use deoplete instead.

Installation

Note: neocomplete requires Vim 7.3.885+ with Lua enabled.
See requirements if you aren't sure whether you have this.

1. Extract the files and put them in your Vim directory
   (usually ~/.vim/ or Program Files/Vim/vimfiles on Windows).
2. Execute the :NeoCompleteEnable command or set `let
   g:neocomplete#enable_at_startup = 1 in your .vimrc (**not** in .gvimrc`

or _gvimrc!)

Requirements

neocomplete requires Vim 7.3.885+ compiled with
if_lua. If `:echo
has("lua") returns 1`, then you're done; otherwise, see below.

Vim builds for Windows

github release

• Vim 32bit
• Vim 64bit
• Vim 32bit alternative
• Another alternative

Note: the Vim build may not include the Lua DLL. In that case,
download Lua and put the lua52.dll
file in the same directory as gvim.exe.

Vim for Mac OS X:

MacVim with if\_lua

Or, you can install MacVim with homebrew: (Make sure you have Xcode fully
installed)

brew cask install macvim --with-cscope --with-lua

To install Vim (as opposed to MacVim) with homebrew:

brew install vim --with-luajit

Vim for Linux:

Debian (or Ubuntu)

Make sure you have any of these packages:

• vim-nox
• vim-gtk3

Which package depends on your graphical environment (except vim-nox which is
for vim with no GUI).

Fedora

The latest version of vim includes lua.
As of 2014-04-16 you need to [download the
rpm](http://koji.fedoraproject.org/koji/packageinfo?packageID=216).

Misc

Be aware, your distribution's package manager may have a fairly outdated
Vim build (for example, Ubuntu 12.04 ships Vim 7.3.429).
However, building Vim on Linux is not

1. Remember to specify --with-lua (or --with-features=huge).

Vim for Cygwin:

In a cygwin environment, the Lua interface is supported by default.

If you want to make manually, you also need gcc and make.

When everything is prepared, execute these commands.

cd /usr/src
tar jxf vim-7.4.tar.bz2
tar xvfz lua-5.1.5.tar.gz
cd vim74/
./configure --enable-luainterp --enable-gui=no \
--without-x --enable-multibyte --prefix=/usr
make && make install

To check if everything was successfull enter the following vim --version. You
should see +lua in the list of features.

Snippets

The Snippets feature of neocomplete was split into a
separate plugin.

A migration guide for existing users of neocomplcache is available:
