FZF :HEART: VIM *fzf-vim-fzf-heart-vim*
|
||
==============================================================================
|
||
|
||
A set of {fzf}{1}-based Vim commands and mappings.

RATIONALE *fzf-vim-rationale*
|
||
==============================================================================
|
||
|
||
{fzf}{1} in itself is not a Vim plugin, and the official repository only
|
||
provides the {basic wrapper function}{2} for Vim and it's up to the users to
|
||
write their own Vim commands with it. However, I've learned that many users of
|
||
fzf are not familiar with Vimscript and are looking for the "default"
|
||
implementation of the features they can find in the alternative Vim plugins.
|
||
|
||
This repository is a bundle of fzf-based commands and mappings extracted from
|
||
my {.vimrc}{3} to address such needs. They are not designed to be flexible or
|
||
configurable, nor are not guaranteed to be backward-compatible at the moment,
|
||
so you might want to treat this repository as a reference.

`fzf#complete` is a helper function for creating custom fuzzy completion using
|
||
fzf. If the first parameter is a command string or a Vim list, it will be used
|
||
as the source.
|
||
>
|
||
" Replace the default dictionary completion with fzf-based fuzzy completion
|
||
inoremap <expr> <c-x><c-k> fzf#complete('cat /usr/share/dict/words')
|
||
<
|
||
For advanced uses, you can pass an options dictionary to the function. The set
|
||
of options is pretty much identical to that for `fzf#run` only with the
|
||
following exceptions:
|
||
|
||
- `reducer` (funcref)
|
||
- Reducer transforms the output lines of fzf into a single string value
|
||
- `prefix` (string; default: `\k*$`)
|
||
- Regular expression pattern to extract the completion prefix
|
||
- Both `source` and `options` can be given as funcrefs that take the completion
|
||
prefix as the argument and return the final value
|
||
- `sink` or `sink*` are not allowed
|
||
|
||

||

inoremap <expr> <c-x><c-s> fzf#complete({
