Hello.
Thanks for the rc. I tried it on Linux. I am afraid it doesn't work. The problem is with:
color brightcyan start="^" end="$"
Getting rid of this line solves the problem. Weird expression indeed.
Otherwise works like a charm.

I was almost sure, this would cause problems somewhere. :)
What version of nano are you using? Maybe there's a way to work around this.

It's nano 2.2.2 on Ubuntu 10.04 LTS (64 bit).

@ruphert You should probably comment line #19, this is a weird way that seems to work in nano 2.0.x, but other versions don't support it.

@koraktor I have successfully been using your git.nanorc file for syntax highlighting with Ubuntu 12.10 and I very much appreciate your work. However, when I upgraded to Ubuntu 13.04 the syntax highlighting stopped working, i.e all text is rendered in a dark grey color. If I remove the include of git.nanorc from my ~/.nanorc file all text is rendered in white, so it seems like nano is still able to detect the include of git.nanorc.

Do you have any idea what the problem might be?

@koraktor I am sorry for bothering you. Apparently the Ubuntu upgrade included localization of Git's messages into the language I have set for the desktop, which is Swedish. I have created a version of git.nanorc updated for Swedish and plan to upload it to GitHub shortly.

Hi, simply changing line to :
color brightcyan start="^." end=".$"
worked for me with nano 2.2.6
