Examples for fish shell

Navigation

function fzf-bcd-widget -d 'cd backwards'
	pwd | awk -v RS=/ '/\n/ {exit} {p=p $0 "/"; print p}' | tac | eval (__fzfcmd) +m --select-1 --exit-0 $FZF_BCD_OPTS | read -l result
	[ "$result" ]; and cd $result
	commandline -f repaint
end

function fzf-cdhist-widget -d 'cd to one of the previously visited locations'
	# Clear non-existent folders from cdhist.
	set -l buf
	for i in (seq 1 (count $dirprev))
		set -l dir $dirprev[$i]
		if test -d $dir
			set buf $buf $dir
		end
	end
	set dirprev $buf
	string join \n $dirprev | tac | sed 1d | eval (__fzfcmd) +m $FZF_CDHIST_OPTS | read -l result
	[ "$result" ]; and cd $result
	commandline -f repaint
end

Commandline

The following is useful to manipulate the commandline from the result of jobs. For instance, calling fzf-select over pacman -Qlq fzf will allow you to select files in the fzf package and print them bck to commandline for further manipulation.

function fzf-select -d 'fzf commandline job and print unescaped selection back to commandline'
	set -l cmd (commandline -j)
	[ "$cmd" ]; or return
	eval $cmd | eval (__fzfcmd) -m --tiebreak=index --select-1 --exit-0 | string join ' ' | read -l result
	[ "$result" ]; and commandline -j -- $result
	commandline -f repaint
end

Completion

The following can replace fish completion menu with fzf. Because of a fish bug this will fail on variables and other elements that need escaping (or not).

function fzf-complete -d 'fzf completion and print selection back to commandline'
	set -l complist (complete -C(commandline -c))
	set -l result
	string join -- \n $complist | sort | eval (__fzfcmd) -m --tiebreak=index --select-1 --exit-0 --header '(commandline)' | cut -f1 | while read -l r; set result $result $r; end

	for i in (seq (count $result))
		set -l r $result[$i]
		## We need to escape the result.
		switch (string sub -s 1 -l 1 -- (commandline -t))
			case "'"
				commandline -t -- (string escape -- (eval "printf '%s' '$r'"))
			case '"'
				set -l quoted (string escape -- (eval "printf '%s' '$r'"))
				set -l len (string length $quoted)
				commandline -t -- '"'(string sub -s 2 -l (math $len - 2) (string escape -- (eval "printf '%s' '$r'")))'"'
			case '~'
				commandline -t -- (string sub -s 2 (string escape -n -- (eval "printf '%s' '$r'")))
			case '*'
				commandline -t -- (string escape -n -- (eval "printf '%s' '$r'"))
		end
		[ $i -lt (count $result) ]; and commandline -i ' '
	end

	commandline -f repaint
end

Git

function fco -d "Fuzzy-find and checkout a branch"
  git branch --all | grep -v HEAD | string trim | fzf | xargs git checkout
end

function fcoc -d "Fuzzy-find and checkout a commit"
  git log --pretty=oneline --abbrev-commit --reverse | fzf +s | xargs git checkout
end

SSH

function fssh -d "Fuzzy-find ssh host and ssh into it"
  ag '^host [^*]' ~/.ssh/config | cut -d ' ' -f 2 | fzf | xargs -o ssh
end

Tmux

function fs -d "Switch tmux session"
  tmux list-sessions -F "#{session_name}" | fzf | xargs tmux switch-client -t
end

LastPass CLI

function fpass -d "Fuzzy-find a Lastpass entry and copy the password"
  if not lpass status -q
    lpass login $EMAIL
  end

  if not lpass status -q
    exit
  end

  lpass ls | fzf | string replace -r -a '.+\[id: (\d+)\]' '$1' | xargs lpass show -c --password
end
