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

*fzf-vim-1*
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*
-----------------+---------------------------------------------------------------------
Command | List ~
-----------------+---------------------------------------------------------------------
`Files[PATH]` | Files (similar to `:FZF` )
`Buffers` | Open buffers
`Colors` | Color schemes
`Ag[PATTERN]` | {ag}{5} search result (CTRL-A to select all, CTRL-D to deselect all)
`Lines` | Lines in loaded buffers
`Marks` | Marks
`Tags` | Tags in the project ( `ctags-R` )
`BTags` | Tags in the current buffer
`LocatePATTERN` | `locate` command output
`History` | `v:oldfiles` and open buffers
`Snippets` | Snippets ({UltiSnips}{6})
`Commands` | User-defined commands
-----------------+---------------------------------------------------------------------
- Most commands support CTRL-T / CTRL-X / CTRL-V key bindings to open in a new
tab, a new split, or in a new vertical split.
- Bang-versions of the commands (e.g. `Ag!`) will open fzf in fullscreen

< Completion helper >_________________________________________________________~
*fzf-vim-completion-helper*
*fzf-vim-4-2*
`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

function! s:make_sentence(lines)
return substitute(join(a:lines), '^.', '\=toupper(submatch(0))', '').'.'
endfunction
inoremap <expr> <c-x><c-s> fzf#complete({
\ 'source': 'cat /usr/share/dict/words',
\ 'reducer': function('<sid>make_sentence'),
\ 'options': '--multi --reverse --margin 15%,0',
\ 'left': 20})
