I've started one here https://github.com/teto/fzf-gems . Will try to beef up the readme

Very nice! Any objection to replacing fzf with fzf-tmux in fzf-down?

I had an issue getting gh to work, changing grep to command grep fixed the issue

thanks for scripts

One of the things that I find useful with these helpers is the ability to do a diff of two hash key.
You don't know the hashes by heart so you type: git diff <C-g><C-h> and you can select the hashes you want to diff. But I do have issues if I have the following entry in my inputrc: set editing-mode vi and set keymap vi-command.
The behavior becomes different, instead of copying the hashes right on the line I was on originally such as the result is git diff <hash1> <hash2> it instead pastes the hashes above the line I was on. Does anybody know how to solve this issue?
Thanks for the help

This is bloody amazing! In my case, the functions weren't working, and as it turns out it was because these conflicted with some existing function somewhere. So, I just prefixed all of your functions with fn- (e.g. fn-gt rather than gt) and now all seem to work beautifully.

I had some problems with gb and gr, due to ambiguity between names of branches, remotes, and paths. Here are the revised functions:

gb() {
  is_in_git_repo || return
  git branch -a --color=always | grep -v '/HEAD\s' | sort |
  fzf-down --ansi --multi --tac --preview-window right:70% \
    --preview 'git log --oneline --graph --date=short --pretty="format:%C(auto)%cd %h%d %s" $(sed s/^..// <<< {} | cut -d" " -f1) -- | head -'$LINES |
  sed 's/^..//' | cut -d' ' -f1 |
  sed 's#^remotes/##'
}

gr() {
  is_in_git_repo || return
  git remote -v | awk '{print $1 "\t" $2}' | uniq |
  fzf-down --tac \
    --preview 'git log --oneline --graph --date=short --pretty="format:%C(auto)%cd %h%d %s" --remotes={1} | head -200' |
  cut -d$'\t' -f1
}

Just solved another problem due to the fact that grep -o "[a-f0-9]\{7,\}" will not only match the Git hashes, but also a string like "feedback". gh is fixed as follows:

gh() {
  is_in_git_repo || return
  git log --date=short --format="%C(green)%C(bold)%cd %C(auto)%h%d %s (%an)" --graph --color=always |
  fzf-down --ansi --no-sort --reverse --multi --bind 'ctrl-s:toggle-sort' \
    --header 'Press CTRL-S to toggle sort' \
    --preview 'grep -o "[a-f0-9]\{7,\}" <<< {} | head -1 | xargs git show --color=always | head -'$LINES |
  grep -o "[a-f0-9]\{7,\}" | head -1
}

for anyone who has oh-my-zsh there are already some alias so the solution is to add a prefix to the functions and modify the helper

fzf_gf() {
...
}

fzf_gb() {
...
}

fzf_gt() {
...
}

fzf_gh() {
...
}

fzf_gr() {
...
}

bind-git-helper() {
  local c
  for c in $@; do
    eval "fzf-g$c-widget() { local result=\$(fzf_g$c | join-lines); zle reset-prompt; LBUFFER+=\$result }"
    eval "zle -N fzf-g$c-widget"
    eval "bindkey '^g^$c' fzf-g$c-widget"
  done
}

Thanks for the work. There's a tiny issue that I met. When started with --preview option, it's really slow to scroll the preview pane with mouse. If there're many lines there, it'll take a long time. Any ideas to scroll faster ?

I can't get this working with pure prompt https://github.com/sindresorhus/pure

Always getting this:

prompt_pure_async_callback:11: bad set of key/value pairs for associative array

nvm, its conflict with existing gf function. I just prefixed it

I am using git bash on Windows and I am getting error like << was unexpected at this time. on those function using <<< {}, any thoughts?

f_gh() {                                                                                                                  
  is_in_git_repo || return                                                                                                
  git log --date=short --format="%C(green)%C(bold)%cd %C(auto)%h%d %s (%an)" --graph --color=always |                     
  fzf-down --ansi --no-sort --reverse --multi --bind 'ctrl-s:toggle-sort' \                                               
    --header 'Press CTRL-S to toggle sort' \                                                                              
    --preview 'grep -o "[a-f0-9]\{7,\}" <<< {} | xargs git show --color=always | head -'$LINES | grep -o "[a-f0-9]\{7,\}" 
}                                                                                                                         

but actually below script works:

huangjoh@SHAPC0N4NVD MINGW64 /m/x-hub/cosv2/flask-app (test-branch-1)
$ grep -o "[a-f0-9]\{7,\}" <<< "* 2019-01-04 2884e18"
2884e18

I've to change the function to use --preview 'echo {} | grep -o "[a-f0-9]\{7,\}" | xargs git show --color=always | head -'$LINES | grep -o "[a-f0-9]\{7,\}" and it works fine.

Great tool!

hmmm. I can't seem to get bindings of the form ^G^$c to work. if i bind the widget directly to a single keypress (bindkey '^B' fzf-gb-widget) it works as expected, but with multi-key bindings, I get nothing.

ZSH in vi-mode

Do you have ^G already bound to something else? I had to remove a binding for my setup (with bindkey -r "^G") before I could use the the ^G prefix.

That was it! Also in this process, I've discovered that bindkey "<binding>" will print the existing functionality of the key. ^G in my case was list-expand

Ah, cool. It looks like gists won't let me add a ":+1:" to comments :). Yep, and bindkey w/out any arguments will list EVERY bindings.

This is beyond awesome. Thank you for making my console perfect with this tools.

the main problem with me was the function names.

Maybe june could update his gist to rename all functions fzf_gr or something similar

i also couldnt use Ctl-G Ctrl-H because of my tmux/vim bindings on Ctrl-H which would change pane so I had to rebrand that to Ctrl-M for comMits or maybe Ctrl-G Ctrl-G (since the hash is the building block of git after all it also makes some sense)

When I put any of these bindings into my ~/.inputrc I lose the ability to enter b into my terminal and iTerm2. When I enter b it instead sends a " character and makes the invalid input sound (displays the bell as well in iTerm). I'm not seeing anything under bind -P that catches my eye, but I'm not really sure what I'm looking for. I have no custom bindings I know of, my bash version is 5.0.11(1)-release and I'm on MacOS.

i never used inputrc so i have no idea what that is.
have you tried doing the suggestions recommended above?
add a fzf_ prefix to all functions . make sure you have everything correctly copy pasted etc.
also bonus points for you: try kitty terminal. iterm2 is just so so slow

Thanks for the response - I will try and kitty when I get some time.
I actually got the key-bindings working using a bash line editor replacement, ble.sh, that I use for fish-like autosuggestions and more. Here's a note about getting these bindings to work.

Cool gist! keybinding.zsh can be further simplified to just:

() {
  local c
  for c in $@; do
    eval "fzf-g$c-widget() { local -r result=(\${(f)\"\$(_g$c)\"}); zle reset-prompt; LBUFFER+=\${(j: :)\${(q)result}} }"
    eval "zle -N fzf-g$c-widget"
    eval "bindkey '^g^$c' fzf-g$c-widget"
  done
} f b t r h s

For some friends using zsh vi mode but the keybindings do not work:
^g is already assigned to zsh builtin standard widget list-expand, so we should remove it first by bindkey -r '^g'.

I am using git bash on Windows and I am getting error like << was unexpected at this time. on those function using <<< {}, any thoughts?

@ztou I found that issue today. Turns out you need to start your git bash session with -l flag, so the subprocess that fzf starts for the preview is still gitbash. then the <<< operator will work.

You can even do some crazy stuff like creating a string to make it work from powershell using git bash.

function _gh () {
  if (-not (git rev-parse HEAD 2> $null)) { return }
  bash -lc @'
    git log --date=short --format='%C(green)%C(bold)%cd %C(auto)%h%d %s (%an)' --graph --color=always |
    fzf --height 50% --min-height 20 --border --bind ctrl-/:toggle-preview --ansi --no-sort --reverse --multi --bind 'ctrl-s:toggle-sort' \
      --header 'Press CTRL-S to toggle sort' \
      --preview 'grep -o \"[a-f0-9]\{7,\}\" <<< {} | xargs git show --color=always | bat -p --color=always' |
    grep -o '[a-f0-9]\{7,\}'
'@
}

I'd like to ask the reason why some commands in the pipes are after fzf

Here is what I mean. Take _gb as an example.

_gb() {
  is_in_git_repo || return
  git branch -a --color=always | grep -v '/HEAD\s' | sort |
  fzf-down --ansi --multi --tac --preview-window right:70% \
    --preview 'git log --oneline --graph --date=short --color=always --pretty="format:%C(auto)%cd %h%d %s" $(sed s/^..// <<< {} | cut -d" " -f1)' |
  sed 's/^..//' | cut -d' ' -f1 |
  sed 's#^remotes/##'
}

The part sed 's/^..//' | cut -d' ' -f1 | sed 's#^remotes/##' at the bottom does not make much sense to me as fzf will display the results before these commands. Is there any reason to call them at the end?

As I can see, the above command can be simplified

_gb() {
  is_in_git_repo || return
  git branch -a --color=always | grep -v '/HEAD\s' | sort |
  sed 's/^..//' | cut -d' ' -f1 |
  fzf-down --ansi --multi --tac --preview-window right:70% \
    --preview 'git log --oneline --graph --date=short --color=always --pretty="format:%C(auto)%cd %h%d %s" {}' 
}

or if you want to include the sed part remove the word "remotes/"

_gb() {
  is_in_git_repo || return
  git branch -a --color=always | grep -v '/HEAD\s' | sort |
  sed 's/^..//' | cut -d' ' -f1 | sed 's#remotes/##'
  fzf-down --ansi --multi --tac --preview-window right:70% \
    --preview 'git log --oneline --graph --date=short --color=always --pretty="format:%C(auto)%cd %h%d %s" {}' 
}

@DanSM-5 Pipe a command after fzf means pass the selection(s) from fzf into this command for further processing.

To implement a feature, you can process the data first and then pass them into fzf and make selections to get what you need, or you can first pass the data into fzf and then post-process the selections to get what you need.

@rockyzhang24 I see, I was pretty much using this for the visualization but that's a nice part too.
For the _gb function, I just noticed that moving those commands above will remove the * for the current branch. So it is likely intentional to leave it in fzf list output. I was only paying attention to the color highlight so I really missed that.

If you use a non-standard diff tool (such as bcompare), you'll need to tell git to use the built-in with the --no-ext-diff flag:

_gf() {
  is_in_git_repo || return
  git -c color.status=always status --short |
  fzf-down -m --ansi --nth 2..,.. \
    --preview '(git diff --no-ext-diff --color=always -- {-1} | sed 1,4d; cat {-1})' |
  cut -c4- | sed 's/.* -> //'
}
