Replace history menu with live history search

[jasonvarga]

Is it possible to bind ↑ to live history search instead of the standard history menu?

They seem pretty much the same to me, but being able to use fzf is really nice.

Yes, that's possible. You'll have to write some code, but it's fairly trivial:

zle -N up-line-or-search
up-line-or-search() {
  if [[ $LBUFFER == *$'\n'* ]] then
    zle up-line
  else
    zle history-incremental-search-backward -w
  fi
}

being able to use fzf is really nice

…except zsh-autocomplete's live history search does not use fzf in any way, shape or from. 🙂

When I press ctrl+r I see different things depending on whether fzf is installed or not.

Without fzf:

With fzf:

ctrl+s uses the non-fzf thing though. Do I have something conflicting?

If you source fzf's keybindings.zsh after sourcing zsh-autocomplete, then the former will override the keybindings of the latter.

Ergo:

• If you want ^R to use fzf, then source zsh-autocomplete before keybindings.zsh.
• If you want ^R to work the same as ^S, then source zsh-autocompleteafter keybindings.zsh. Or alternatively, just don't source keybindings.zsh at all.

Ah, I didn't realize fzf had its own ctrl+r binding. Makes sense.

In that case, I was able to override the up arrow behavior to use fzf history by adding this:

zle -N up-line-or-search
up-line-or-search() {
  if [[ $LBUFFER == *$'\n'* ]] then
    zle up-line
  else
    fzf-history-widget
  fi
}

Thanks for the help!
