My Zsh is super slow inside a certain Git repo of mine. When I Google "zsh git slow", I get a bunch of results about Git autocompletion being slow, but autocompletion isn't necessarily my problem; it's everything.

I tried removing all plugins and that, strangely, didn't do anything at all when I opened a new shell. Zsh would still do Git stuff inside my Git repo.

I found this snippet on this page:

function git_prompt_info() {
  ref=$(git symbolic-ref HEAD 2> /dev/null) || return
  echo "$ZSH_THEME_GIT_PROMPT_PREFIX${ref#refs/heads/}$ZSH_THEME_GIT_PROMPT_SUFFIX"
}

That made everything fast again, but it also gave me a prompt that looks like this:

➜  snip git:(master

Note the missing right parenthesis. That's kind of lame. Plus the whole thing just seems like a hack I shouldn't have to do.

There's also this promising-looking SU question, but the links on the accepted answer are dead.

How can I get my Zsh not to be slow inside a Git repo?

Can you link us to the SU question you mention? –  slhck Sep 19 '12 at 15:42
    
Also, What did you have in your prompt when things were slow (before your snippet)? –  studgeek Oct 9 '12 at 12:01

It's not that autocompletion is slow, it's that autocompletion makes every command seem slow because you are waiting for it to source stuff. Trying commenting out bash_completion completely in your zsh dot files.

There doesn't seem to be anything relevant there to comment out. –  Jason Swett Oct 7 '12 at 0:52
