fzf-preview is a (Neo)vim plugin and coc extension written in TypeScript that provide powerful integration with fzf. It provides multiple presets for fzf and correspondingly powerful preview functionality. It also provides advanced interactive git integration.

Since fzf-preview.vim implements RPC in the Vim script, it will work in both Vim and Neovim if you use the RPC release. It can also be installed as Remote Plugin and coc extensions. If you want to use the integration with coc, install coc extensions.

Introductory Article (Japanese)

This plugin can be easily extended in comparison to fzf.vim.

e.g. Fugitive(launch git commands), bdelete(delete a selected buffer from the buffer list)

Features

Provides an excellent UI with floating windows by default
Supports devicons and output highlighting by default
Preview the selected item (with an arbitrary command)
Fast file and buffer search by fuzzy matching
Search all project files and history
Search from file history files using oldfiles and mru
Interactive git integration (with Fugitive or Gina)
Jump lines from jumplist or changelist
Interactive grep and preview from the current project
Export the selected items to QuickFix.

" Most commands are passed a file path to the process function.
" FzfPreviewAllBuffers will be passed “buffer {bufnr}”
"
" Value example: let g:foo_processes = {
"                \ '':       'FzfPreviewOpenFileEnter',

"

--add-fzf-arg
" Set the arguments to be passed when executing fzf.
" This value is added to the default options.
" Value must be a string without spaces.

" Example: Exclude filename with FzfPreviewProjectGrep
nnoremap <Leader>g :<C-u>FzfPreviewProjectGrep --add-fzf-arg=--nth=3<Space>
" nnoremap <Leader>g :<C-u>CocCommand fzf-preview.ProjectGrep --add-fzf-arg=--nth=3<Space>


--resume
" Reuse the input that was last used to select the element with fzf.
" Do not need to pass a value for this option.

" Example: Reuse last query for project grep.
nnoremap <Leader>G :<C-u>FzfPreviewProjectGrep . --resume<Space>
" nnoremap <Leader>G :<C-u>CocCommand fzf-preview.ProjectGrep . --resume<Space>
