History search not working about fzf

[junegunn]

What's the version of your zsh?

zsh --version

Is the problem still reproducible on zsh without any configuration?

zsh -d -f

source <(fzf --zsh)

# Or if fzf is not in your $PATH
source <(~/.fzf/bin/fzf --zsh)

[0xBigBoss]

same issue. tried with the homebrew zsh and apple zsh.

zsh --version
zsh 5.9 (x86_64-apple-darwin23.0)

opt/homebrew/bin/zsh --version
zsh 5.9 (arm-apple-darwin23.0.0)

Could you share the output when running the following commands one after another?

# Improved trace prompt
PS4='%B%F{0}+ %D{%T:%3.} %2N:%i%f%b '
# Clears current shell history to minimize debug output
fc -p =(<<<"")

unsetopt KSH_OPTION_PRINT
setopt
fzf --version
source <(fzf --zsh)
# Enable tracing for the function
typeset -fT fzf-history-widget
# Press Ctrl-R, then Enter

[junegunn]

CTRL-R uses Perl since 0.53.0. Could this be a problem with the Perl installation? perl --version?

[0xBigBoss]

here is the trace outputs

I tried with apple perl (v5.34.1) and homebrew perl (v5.38.2).

It looks like your "grep" is injecting color codes to the output when it shouldn't. What is the output of type grep?

[0xBigBoss]

@junegunn great find. I have GREP_OPTIONS set.

GREP_OPTIONS=--color=always -I --exclude=tags --exclude-dir={.svn,.git,target}

grep is an alias for grep --color=auto --exclude-dir={.bzr,CVS,.git,.hg,.svn,.idea,.tox}
grep --version
grep (BSD grep, GNU compatible) 2.6.0-FreeBSD

Unsetting it and fzf works again.
