An attempt at implementing support for selecta in neovim

selecta_command.vim

function! SelectaCommand(choice_command, selecta_args, vim_command)
  let dict = { 'buf': bufnr('%'), 'vim_command': a:vim_command, 'temps': { 'result': tempname() }, 'name': 'SelectaCommand' }

  function! dict.on_exit(id, code)
    bd!

    if a:code != 0
      return 1
    endif

    if filereadable(self.temps.result)
      let l:selection = readfile(self.temps.result)[0]

      exec self.vim_command." ".l:selection
    else
      echom "selecta: error: can't read selection from (".self.temps.result.")"
    endif
  endfunction

  if a:vim_command != ':e'
    exec 'split '.dict.buf
  endif

  call termopen(a:choice_command." | selecta ".a:selecta_args." > ".dict.temps.result, dict)

  setf dict
  startinsert
endfunction

nnoremap <leader>p :call SelectaCommand("selecta-command", "", ":e")<cr>

This works nicely, thanks for sharing!
