" vim plugin to use nnn as a file picker
" Closely follows and inspired by the vim_file_chooser plugin for ranger.
"
" Author: Arun Prakash Jana

" Copyright © 2018 Arun Prakash Jana
"
" Usage:
" Copy this file to the vim plugin directory.
" To open nnn as a file picker in vim, use the command ":NnnPicker" or ":Np"
" or the key-binding "<leader>n". Once you select one or more files and quit
" nnn, vim will open the first selected file and add the remaining files to
" the arg list/buffer list.
" If no file is explicitly selected, the last selected entry is picked.
function! NnnPicker()
let temp = tempname()
if has("gui_running")
exec 'silent !xterm -e nnn -p ' . shellescape(temp)
else
exec 'silent !nnn -p ' . shellescape(temp)
endif
if !filereadable(temp)
redraw!
" Nothing to read.
return
endif
let names = readfile(temp)
if empty(names)
redraw!
" Nothing to open.
return
endif
" Edit the first item.
exec 'edit ' . fnameescape(names[0])
" Add any remaining items to the arg list/buffer list.
for name in names[1:]
exec 'argadd ' . fnameescape(name)
endfor
redraw!
endfunction
command! -bar NnnPicker call NnnPicker()
nnoremap <leader>n :<C-U>NnnPicker<CR>
command! -nargs=* -complete=file Np :call NnnPicker()
