fzf ❤️ coc.nvim

Use FZF instead of coc.nvim built-in fuzzy finder.

Rationale

This plugin uses FZF fuzzy finder in place of Coc's built-in CocList sources as well as Coc's jumps (definition, reference etc).
It makes the interaction with Coc easier when you are used to FZF.

The main features are:

• FZF preview
• FZF bindings for splits and tabs
• FZF layout (floating windows etc)
• FZF multi-select to populate the quickfix window

It was inspired by Robert Buhren's functions and coc-denite.

Installation

Make sure to have the following plugins in your vimrc:

Plug 'junegunn/fzf', {'dir': '~/.fzf','do': './install --all'}
Plug 'junegunn/fzf.vim' " needed for previews
Plug 'neoclide/coc.nvim', {'do': 'yarn install --frozen-lockfile'}
Plug 'antoinemadec/coc-fzf'

Or, if you prefer using the release branch:

Plug 'junegunn/fzf', {'dir': '~/.fzf','do': './install --all'}
Plug 'junegunn/fzf.vim' " needed for previews
Plug 'neoclide/coc.nvim', {'branch': 'release'}
Plug 'antoinemadec/coc-fzf', {'branch': 'release'}

Also consider installing bat for colorful previews.

Wrapper Sources

Not every list source is implementable with FZF.
For those sources, :CocFzfList acts as a wrapper calling :CocList

Wrapper Sources appear with the [wrapper] mention when running :CocFzfList

Add/Delete Sources

" add_list_source(name, description, command)
call coc_fzf#common#add_list_source('fzf-buffers', 'display open buffers', 'Buffers')

" delete_list_source(name)
call coc_fzf#common#delete_list_source('fzf-buffers')

Options

Option	Type	Description	Default value
g:coc_fzf_preview_toggle_key	string	Change the key to toggle the preview window	'?'
g:coc_fzf_preview_fullscreen	number	Set to 1 to use FZF fullscreen mode in coc-references etc.	0
g:coc_fzf_preview	string	Change the preview window position	'up:50%'
g:coc_fzf_opts	array	Pass additional parameters to fzf, e.g. ['--layout=reverse']	['--layout=reverse-list']
g:coc_fzf_location_delay	number	Delay(ms) fzf_run() to solve weird race conditions.	0

FAQ

Q: How to get the FZF floating window?
A: You can look at FZF Vim integration:

let g:fzf_layout = { 'window': { 'width': 0.9, 'height': 0.6 } }

Q: How to see references, definitions etc in a FZF window?
A: It is already supported by default, just make sure to have the default coc mappings:

nmap <silent> gd <Plug>(coc-definition)
nmap <silent> gy <Plug>(coc-type-definition)
nmap <silent> gi <Plug>(coc-implementation)
nmap <silent> gr <Plug>(coc-references)

Q: How to get colors in previews?
A: Install bat.

Q: CocFzf looks different from my other Fzf commands. How to make it the same?
A: By default, CocFzf tries to mimic CocList. Here is how to change this:

let g:coc_fzf_preview = ''
let g:coc_fzf_opts = []

Q: CocFzf symbol search reports get_workspace_symbols.py could not be executed successfully A: You are most likely missing pynvim
