Most of the examples are taken from fzf wiki:

Table of Contents

Ex: Run fzf with shell find and send output to Vim’s e command

call fzf#run({'sink': 'e'})

fzf#run() function takes a dictionary as argument. This dictionary has two important keys: sink and source. sink is the channel where fzf output is redirected. source is the data stream where fzf makes search.

For example, the above function call uses the default source which is the default find command. The sink is e command of Vim. Thus it will open the selected file with e.

Instead of e we could also use tabedit

call fzf#run({'sink': 'tabedit'})

Ex: Use other shell comands in input data stream

Or instead of using the default find command as input data stream, we can use any shell command that produces some data stream. For example:

call fzf#run({'source': 'git ls-files', 'sink': 'e'})

Ex: Use a Vim array as input data stream

source can be a vim array too. The following uses names of open buffers as source:

call fzf#run({'source': map(split(globpath(&rtp, 'colors/*.vim'))
            \               , 'fnamemodify(v:val, ":t:r")')
            \ , 'sink': 'e'})

Ex: List all open buffers:

command! Buffers call fzf#run(fzf#wrap( {'source': map(range(1, bufnr('$')), 'bufname(v:val)')}))

Ex: Open Fzf buffer as normal Vim buffer

fzf#wrap opens fzf using g:fzf_layout setting

call fzf#run( fzf#wrap({'sink': 'e'}) )

Ex: locate or mdfind command to open any file

mdfind command is used in osx to search contents of all documents.

command! -nargs=1 -bang Mdfind call fzf#run(fzf#wrap( {'source': 'mdfind <q-args>', 'options': '-m'}, <bang>0))
command! -nargs=1 -bang Mdfind call fzf#run(fzf#wrap(
      \ {'source': 'mdfind <q-args>', 'options': '-m'}, <bang>0))
