How to remove the space in front of the matched content that transfered to sink Vim FZF?

Question

Fzf seems to automatically add spaces in front of the matched content, And then transfer it to sink.

let g:vimspector_json_path=$HOME . "/.config/vimspector_template/"
command! -bang -nargs=* LoadVimSpectorJson call fzf#run({
            \   'source': 'ls ' . vimspector_json_path,
            \   'sink': 'e .vimspector.json | 0r' . vimspector_json_path,
            \   'down': '25%',
            \   'options': '--preview-window=hidden'
            \ })

Vim(read):E484: Can't open file /home/lee/.config/vimspector_template/ python.json

Error because of the space before the filename python.json .

Is there any way to remove this space?

Answer 1

You can create an additional user-command to load a template by name and do the directory concatenation in that command.

For example:

command! -bar -nargs=1 LoadVimSpectorTemplate
    \ execute "0r ".g:vimspector_json_path.<q-args>

So :LoadVimSpectorTemplate python.json will load that template file from the vimspector template directory.

In your fzf#run() call, you can then use:

'sink': 'e .vimspector.json | LoadVimSpectorTemplate'
