Thanks for the code anyway!

Edit: revised & expanded here.

Here's the version that adds the entry to the commandline. I'm sure there's a better way of doing this in fish — feel free to critique.

# Deciphered from fzf-file-widget. Somewhat unclear why it doesn't exist already!
function fzf_add_to_commandline -d 'add stdin to the command line, for fzf functions'
  read -l result
  commandline -t ""
  commandline -it -- (string escape $result)
  commandline -f repaint
end

Awesome work 👍 just want to mention fzf.fish also provides key bindings for git log, git status and more.

Awesome work 👍 just want to mention fzf.fish also provides key bindings for git log, git status and more.

fzf.fish is very sluggish for me, and exhibits weird behavior. The author also disabled issues and PRs. Hopefully this gist provides a good alternative, haven't tried it yet, but it looks promising!
