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


On macOS `tac` isn't available by default but you can use `tail -r` instead of `tac` for the same functionality.

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 --tiebreak=index --toggle-sort=ctrl-r $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](https://github.com/fish-shell/fish-shell/issues/3469) 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'

# As of 2.6, fish's "complete" function does not understand

# subcommands. Instead, we use the same hack as __fish_complete_subcommand and

# extract the subcommand manually.

set -l cmd (commandline -co) (commandline -ct)

switch $cmd[1]

case env sudo

for i in (seq 2 (count $cmd))

switch $cmd[$i]

case '-*'

case '*=*'

case '*'

set cmd $cmd[$i..-1]

break

end

end

end

set cmd (string join -- ' ' $cmd)

set -l complist (complete -C$cmd)

set -l result

string join -- \n $complist | sort | eval (__fzfcmd) -m --select-1 --exit-0 --header '(commandline)' | cut -f1 | while read -l r; set result $result $r; end

set prefix (string sub -s 1 -l 1 -- (commandline -t))

for i in (seq (count $result))

set -l r $result[$i]

switch $prefix

case "'"

commandline -t -- (string escape -- $r)

case '"'

if string match '*"*' -- $r >/dev/null

commandline -t -- (string escape -- $r)

else

commandline -t -- '"'$r'"'

end

case '~'

commandline -t -- (string sub -s 2 (string escape -n -- $r))

case '*'

commandline -t -- (string escape -n -- $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 | read -l result; and git checkout "$result"

end

function fco -d "Use `fzf` to choose which branch to check out" --argument-names branch

set -q branch[1]; or set branch ''

git for-each-ref --format='%(refname:short)' refs/heads | fzf --height 10% --layout=reverse --border --query=$branch --select-1 | xargs git checkout

end

function fcoc -d "Fuzzy-find and checkout a commit"

git log --pretty=oneline --abbrev-commit --reverse | fzf --tac +s -e | awk '{print $1;}' | read -l result; and git checkout "$result"

end

function snag -d "Pick desired files from a chosen branch"

# use fzf to choose source branch to snag files FROM

set branch (git for-each-ref --format='%(refname:short)' refs/heads | fzf --height 20% --layout=reverse --border)

# avoid doing work if branch isn't set

if test -n "$branch"

# use fzf to choose files that differ from current branch

set files (git diff --name-only $branch | fzf --height 20% --layout=reverse --border --multi)

end

# avoid checking out branch if files aren't specified

if test -n "$files"

git checkout $branch $files

end

end

function fzum -d "View all unmerged commits across all local branches"

set viewUnmergedCommits "echo {} | head -1 | xargs -I BRANCH sh -c 'git log master..BRANCH --no-merges --color --format=\"%C(auto)%h - %C(green)%ad%Creset - %s\" --date=format:\'%b %d %Y\''"

git branch --no-merged master --format "%(refname:short)" | fzf --no-sort --reverse --tiebreak=index --no-multi \

--ansi --preview="$viewUnmergedCommits"

end


### SSH

function fssh -d "Fuzzy-find ssh host via ag and ssh into it"

ag --ignore-case '^host [^*]' ~/.ssh/config | cut -d ' ' -f 2 | fzf | read -l result; and ssh "$result"

end


### Tmux

function fs -d "Switch tmux session"

tmux list-sessions -F "#{session_name}" | fzf | read -l result; and tmux switch-client -t "$result"

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 '.+\[id: (\d+)\]' '$1' | read -l result; and lpass show -c --password "$result"

end


### Vscode

function vsr -d "List recently opened files with vscode"

set -l vscode_path "$HOME/.config/VSCodium"

set -l grep

if type -q rg

set grep rg -o --no-line-number

else

set grep grep -o

end

set -l selected (\

$grep '"path": "/.*[^/]"' "$vscode_path/storage.json" \

| string replace -a '"path": ' '' \

| string trim -c '"'\

| fzf --exit-0 )

[ -n "$selected" ]; and codium "$selected"

end


### Clean $PATH

function pathclean --description "Clean up PATH variable"

set PATH (printf "%s" "$PATH" | awk -v RS=':' '!a[$1]++ { if (NR > 1) printf RS; printf $1 }')

end
