@henno that's weird, i've never seen that before, perhaps trying upgrading fish and iterm?
could be wrong but i think all -gx can be replaced with -x because it only need to be exported and it doesn't need to be available as a global variable in the script itself?
@henno The issue is with the grep function. Remove it and it's working fine for me
updated git prompt to be much more efficient. Reduces the number of git command calls from 5->1

updated to remove all grep calls and use fish' built in string matcher which is faster than grep. Now the bottleneck is only on git status

Can you think any reason why, after applying these changes (without GO and JAVA lines), one gets this output when trying to autocomplete a command's parameter in Fish:
