Ripgrep flag 'w' doesn't work

[abenz1267]

Hi,

it seems like ripgreps -w/--word-regexp flag doesn't work.

AttributeError: 'NoneType' object has no attribute 'group'

Is this intended or a bug?

It seems to work in my environment.
Can you give an example of failure using this repository?

Hi,

using it that way works. I put this in my init.vim

let g:fzf_preview_grep_cmd = 'rg --line-number --no-heading -w'
nmap <silent> <A-p> :FzfPreviewProjectGrep<CR>

When i alt+p i got the error straight away. Weirdly now i don't get an error, but it isn't working either.

If no argument is given, FzfPreviewProjectGrep executes a command with a dot after g:fzf_preview_grep_cmd and searches for the project.
Thus, when run without arguments, rg -w . is run.
https://github.com/yuki-ycino/fzf-preview.vim/blob/master/autoload/fzf_preview/command.vim#L21-L27

Adding the -w option seems to require passing the argument each time the command is executed, or specifying the -w option at runtime instead of writing g: fzf_preview_grep_cmd.

Not yet documented, but if necessary, you can easily create new resources using the fzf_preview#parameter and the fzf_preview#runner.

-w option at runtime instead of writing g: fzf_preview_grep_cmd

What do you mean? Typing '-w ' in the preview window doesn't work. Or do you mean directly running FzfPreviewGrep -w <search> as you did? Yes, that works.

Btw: is it possible to remove the files list when the input is empty?

Sorry for not good at english.

fzf narrows the candidates from the list passed at startup.
Therefore, you need to create a candidate list first.
It is possible to use the -w option at that time.
However, after the candidate is passed to fzf, rg is not relevant, so the -w option cannot be used.

FzfPreviewProjectGrep uses . without arguments to use all lines of the project, which is necessary to pass candidates to fzf.
