Note: This plugin is not compatible with above Vim 8.2.1066! https://github.com/vim/vim/commit/bd84617d1a6766efd59c94aabebb044bef805b99
Note: The development of this plugin is finished. Accepts minor patches and issues but no new features. ddc.vim is the next generation auto completion plugin. Consider migrating to it.
neocomplete is the abbreviation of "neo-completion with cache". It provides keyword completion system by maintaining a cache of keywords in the current buffer. neocomplete can be customized easily and has many more features than Vim's built-in completion.
Note: If you use neovim or Vim8+, you should use deoplete instead. https://github.com/Shougo/deoplete.nvim
Note: neocomplete requires Vim 7.3.885+ with Lua enabled. See requirements if you aren't sure whether you have this.
- Extract the files and put them in your Vim directory
(usually
~/.vim/orProgram Files/Vim/vimfileson Windows). - Execute the
:NeoCompleteEnablecommand or setlet g:neocomplete#enable_at_startup = 1in your.vimrc(not in.gvimrcor_gvimrc!)
neocomplete requires Vim 7.3.885+ compiled with
if_lua. If :echo has("lua") returns 1, then you're done; otherwise, see below.
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.
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
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).
The latest version of vim includes lua. As of 2014-04-16 you need to download the rpm.
Be aware, your distribution's package manager may have a fairly outdated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
difficult. Remember to specify --with-lua (or --with-features=huge).
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.
The Snippets feature of neocomplete was split into a separate plugin.
