Fix(vim.vim): Error calling Files when ripgrep is FZF_DEFAULT_COMMAND

[ghost]

related to #657 .

When users set FZF_DEFAULT_COMMAND as rg or rg ~~~, Files command fails. It is because it calls raw fzf which is same as FZF_DEFAULT_COMMAND, but command is supposed to be 'rg --files' to look up files under current directory.

I came up with thinking that I need to fix fzf side, but fzf#vim#grep has same approach replacing FZF_DEFAULT_COMMAND, so I make PR in fzf.vim side.

Thanks, but I don't quite see the point of the pull request. It's up to users to use a correct FZF_DEFAULT_COMMAND. We can't fix it for them as they can use different variations of rg command. e.g. rg --files --hidden, rg --files --hidden --follow, etc.

The reason fzf#vim#grep sets FZF_DEFAULT_COMMAND is very different. It is for reload action. See junegunn/fzf#1750 for details.

Thank you for your reply, but this happens even when user sets FZF_DEFAULT_COMMAND = 'rg' without any options.

It's because ripgrep needs to call 'rg --files' to search files under current directory, however, fzf calls only 'rg' which is just FZF_DEFAULT_COMMAND right now. Therefore I thought it would be useful to call 'rg --files' only when user uses :File.

when user sets FZF_DEFAULT_COMMAND = 'rg' without any options.

That's clearly a misconfiguration. The user, not we, should fix it.

Ah I totally misunderstood,
I add --files in FZF_DEFAULT_COMMAND and now it works.
