Gvim Intellisense with Conquerer of Completion (CoC)

Conquerer of Completion

This plugin is too featureful (bloated) to explain in a single blog post

Good thing the author provided extensive documentation here

Install with vim-plug

" Stable version of coc
Plug 'neoclide/coc.nvim', {'branch': 'release'}

" Keeping up to date with master
Plug 'neoclide/coc.nvim', {'do': 'yarn install --frozen-lockfile'}

make sure you have yarn installed if you choose the second way

npm i -g yarn

Create a directory called plug-config and an entry for coc

mkdir %userprofile%\.config\vim\plug-config


type nul > %userprofile%\.config\plug-config\coc.vim

Create basic config file

Head over to the readme and grab his example config

Add the following to your .vimrc

source $HOME\.config\vim\plug-config\coc.vim

Checking coc health

You can run :checkhealth and there should now be an entry for coc

You can use g:coc_node_path to point to your node executable

You can also run :CocInfo to get some useful info

:CocInstall coc-json coc-python coc-snippets coc-vimlsp
