grep is failing

[jthalliley]

As you can see below, I just re-installed fancy-git, and there's an issue with a grep command in the fancy-git. It seems that "-P" is the issue ... Perl style regex's are experimental and apparently not available on MacOS.

Here's a better screenshot, after I changed fonts to SourceCodePro+Powerline.

Closed by mistake.

I was able to resolve this by doing:

brew install grep
and adding/usr/local/opt/grep/libexec/gnubinto my PATH ahead of /usr/bin.

I wonder if the grep command would work properly even without the -P parameter. This way you should not worry

Hi @jthalliley

I've just reopened this issue because I know how to solve that.

I'll change the way some RegExp are formed here, so I won't need the -P anymore.

Even though your workaround will solve some problems with a few aliases as well.

I'll add that one to the docs, on the troubleshooting session.

Thank you.

Cool thx.

This issue has resurfaced, I guess due to line 27 in a84ff9e#diff-bb471c844bf5fa8652c53f77d6598f589dcf28613d067be0b4808f7c771aa161.

Update: I tried removing the -P option, leaving only -o and I am not seeing any problems. But I did not look into what that line do, so I do not know if it changes any behaviour.

Hi, @jespermbyskov

Thank you for your report.

If you do brew install grep and adding /usr/local/opt/grep/libexec/gnubin to the PATH ahead of /usr/bin that problem might vanish.

Please, let me know if it works for you.

[jespermbyskov]

Thanks, but for now, removing the -P option works for me, so I will just leave it with that.

[diogocavilha]

Hum, I see, just be aware that there are other commands that use this parameter on grep too.

They are: gpsob, guser, guser, grba, gg and gplob

Maybe running brew install grep would solve that problem.

i already install grep and also insert before and it's not solve probem
my PATH :
/usr/local/opt/grep/libexec/gnubin
:/usr/local/bin
:/usr/bin
:/bin
:/usr/sbin
:/sbin
:/Library/TeX/texbin
:/Library/Apple/usr/bin

I'm so sorry for that.

I've been thinking about using grep without that option. It seems to have lots of issues when using Mac OS.

I'll try to solve that on next version.

Having issue like @imtiendat0311 mentioned here

brew install grep followed by export PATH="/opt/homebrew/opt/grep/libexec/gnubin:$PATH" first in my ~/.bash_profile did the thing for me.
