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/.* -> //'
}
