FZF Vim integration
|
|
===================
|
|
|
|
This repository only enables basic integration with Vim. If you're looking for
|
|
more, check out [fzf.vim](https://github.com/junegunn/fzf.vim) project.
|
|
|
|
(Note: To use fzf in GVim, an external terminal emulator is required.)
|
|
|
|
`:FZF[!]`
|
|
---------
|
|
|
|
If you have set up fzf for Vim, `:FZF` command will be added.
|
|
|
|
```vim
|
|
" Look for files under current directory
|
|
:FZF
|
|
|
|
" Look for files under your home directory
|
|
:FZF ~
|
|
|
|
" With options
|
|
:FZF --no-sort --reverse --inline-info /tmp
|
|
|
|
" Bang version starts fzf in fullscreen mode
|
|
:FZF!
|
|
```
|
|
|
|
Similarly to [ctrlp.vim](https://github.com/kien/ctrlp.vim), use enter key,
|
|
`CTRL-T`, `CTRL-X` or `CTRL-V` to open selected files in the current window,
|
|
in new tabs, in horizontal splits, or in vertical splits respectively.
|
|
|
|
Note that the environment variables `FZF_DEFAULT_COMMAND` and
|
|
`FZF_DEFAULT_OPTS` also apply here.
|
|
|
|
### Configuration
|
|
|
|
- `g:fzf_action`
|
|
- Customizable extra key bindings for opening selected files in different ways
|
|
- `g:fzf_layout`
|
|
- Determines the size and position of fzf window (tmux pane or Neovim split)
|
|
- `g:fzf_colors`
|
|
- Customizes fzf colors to match the current color scheme
|
|
- `g:fzf_history_dir`
|
|
- Enables history feature
|
|
- `g:fzf_launcher`
|
|
- (Only in GVim) Terminal emulator to open fzf with
|
|
- `g:Fzf_launcher` for function reference
|
|
|
|
#### Examples
|
|
|
|
```vim
|
|
" This is the default extra key bindings
|
|
let g:fzf_action = {
|
|
\ 'ctrl-t': 'tab split',
|
|
\ 'ctrl-x': 'split',
|
|
\ 'ctrl-v': 'vsplit' }
|
|
|
|
" Default fzf layout
|
|
" - down / up / left / right
|
|
let g:fzf_layout = { 'down': '~40%' }
|
|
|
|
" In Neovim, you can set up fzf window using a Vim command
|
|
let g:fzf_layout = { 'window': 'enew' }
|
|
let g:fzf_layout = { 'window': '-tabnew' }
|
|
let g:fzf_layout = { 'window': '10split enew' }
|
|
|
|
" Customize fzf colors to match your color scheme
|
|
let g:fzf_colors =
|
|
\ { 'fg': ['fg', 'Normal'],
|
|
\ 'bg': ['bg', 'Normal'],
|
|
\ 'hl': ['fg', 'Comment'],
|
|
\ 'fg+': ['fg', 'CursorLine', 'CursorColumn', 'Normal'],
|
|
\ 'bg+': ['bg', 'CursorLine', 'CursorColumn'],
|
|
\ 'hl+': ['fg', 'Statement'],
|
|
\ 'info': ['fg', 'PreProc'],
|
|
\ 'prompt': ['fg', 'Conditional'],
|
|
\ 'pointer': ['fg', 'Exception'],
|
|
\ 'marker': ['fg', 'Keyword'],
|
|
\ 'spinner': ['fg', 'Label'],
|
|
\ 'header': ['fg', 'Comment'] }
|
|
|
|
" Enable per-command history.
|
|
" CTRL-N and CTRL-P will be automatically bound to next-history and
|
|
" previous-history instead of down and up. If you don't like the change,
|
|
" explicitly bind the keys to down and up in your $FZF_DEFAULT_OPTS.
|
|
let g:fzf_history_dir = '~/.local/share/fzf-history'
|
|
```
|
|
|
|
`fzf#run`
|
|
---------
|
|
|
|
For more advanced uses, you can use `fzf#run([options])` function with the
|
|
following options.
|
|
|
|
| Option name | Type | Description |
|
|
| -------------------------- | ------------- | ---------------------------------------------------------------- |
|
|
| `source` | string | External command to generate input to fzf (e.g. `find .`) |
|
|
| `source` | list | Vim list as input to fzf |
|
|
| `sink` | string | Vim command to handle the selected item (e.g. `e`, `tabe`) |
|
|
| `sink` | funcref | Reference to function to process each selected item |
|
|
| `sink*` | funcref | Similar to `sink`, but takes the list of output lines at once |
|
|
| `options` | string/list | Options to fzf |
|
|
| `dir` | string | Working directory |
|
|
| `up`/`down`/`left`/`right` | number/string | Use tmux pane with the given size (e.g. `20`, `50%`) |
|
|
| `window` (*Neovim only*) | string | Command to open fzf window (e.g. `vertical aboveleft 30new`) |
|
|
| `launcher` | string | External terminal emulator to start fzf with (GVim only) |
|
|
| `launcher` | funcref | Function for generating `launcher` string (GVim only) |
|
|
|
|
`options` entry can be either a string or a list. For simple cases, string
|
|
should suffice, but prefer to use list type if you're concerned about escaping
|
|
issues on different platforms.
|
|
|
|
```vim
|
|
call fzf#run({'options': '--reverse --prompt "C:\\Program Files\\"'})
|
|
call fzf#run({'options': ['--reverse', '--prompt', 'C:\Program Files\']})
|
|
```
|
|
|
|
`fzf#wrap`
|
|
----------
|
|
|
|
`fzf#wrap([name string,] [opts dict,] [fullscreen boolean])` is a helper
|
|
function that decorates the options dictionary so that it understands
|
|
`g:fzf_layout`, `g:fzf_action`, `g:fzf_colors`, and `g:fzf_history_dir` like
|
|
`:FZF`.
|
|
|
|
```vim
|
|
command! -bang MyStuff
|
|
\ call fzf#run(fzf#wrap('my-stuff', {'dir': '~/my-stuff'}, <bang>0))
|
|
```
|
|
|
|
GVim
|
|
----
|
|
|
|
In GVim, you need an external terminal emulator to start fzf with. `xterm`
|
|
command is used by default, but you can customize it with `g:fzf_launcher`.
|
|
|
|
```vim
|
|
" This is the default. %s is replaced with fzf command
|
|
let g:fzf_launcher = 'xterm -e bash -ic %s'
|
|
|
|
" Use urxvt instead
|
|
let g:fzf_launcher = 'urxvt -geometry 120x30 -e sh -c %s'
|
|
```
|
|
|
|
If you're running MacVim on OSX, I recommend you to use iTerm2 as the
|
|
launcher. Refer to the [this wiki page][macvim-iterm2] to see how to set up.
