NCM2, formerly known as nvim-completion-manager, is a slim, fast and hackable completion framework for neovim.
Main features:
- Fast and asynchronous completion support, with vimscript friendly API.
- Smart on files with different languages, for example, css/javascript completion in html style/script tag.
- Function parameter expansion support using ncm2-snippet plugins.
Read our wiki page for a list of extensions and languages support for NCM2.

For vim8 user, read the nvim-yarp README. Note that vim8 support is simply a bonus. It's not the goal of NCM2.
