One GIT Build Script to Rule them all

There seem to be at least 2 camps of GIT Users on OS X, those who installed git with the Mac OS X Package installer and those who installed it from Mac Ports. On my new project Gitty (a Git Repo inspector/manager just beginning development), I didn't want to discriminate, but at the same time I didn't know perl well enough to modify Marcus Zarra's Build Script beyond changing /opt/local/bin/git to /usr/local/git/bin/git. However one of my followers on Twitter was kind enough to modify the perl build script that sticks part of the GIT Hash in the about box to search for both locations and use which ever one you have installed so that it is now GIT Location Agnostic. It looks for the standard install location first and then if It can't find that searches for the MacPorts git install location and uses that. This works great for me and so i thought i'd share... enjoy. Thanks

# Xcode auto-versioning script for Subversion by Axel Andersson
# Updated for git by Marcus S. Zarra and Matt Long
# Updated to use git in the Standard Install Location or the MacPorts
#   install location by Patrick Burleson
 
use strict;
 
# Get the current git commit hash and use it to set the CFBundleVersion value
my $REV = "";

if( -e "/usr/local/git/bin/git" ) 
{
    $REV = `/usr/local/git/bin/git show --abbrev-commit | grep "^commit"`;
}
elsif ( -e "/opt/local/bin/git" )
{
    $REV = `/opt/local/bin/git show --abbrev-commit | grep "^commit"`;
}
else 
{
    die "Git not found";
}

my $INFO = "$ENV{BUILT_PRODUCTS_DIR}/$ENV{WRAPPER_NAME}/Contents/Info.plist";
 
my $version = $REV;
if( $version =~ /^commit\s+([^.]+)\.\.\.$/ )
{ 
    $version = $1;
}
else
{
    $version = undef;
}
die "$0: No Git revision found" unless $version;
 
open(FH, "$INFO") or die "$0: $INFO: $!";
my $info = join("", <FH>);
close(FH);
 
$info =~ s/([\t ]+<key>CFBundleVersion<\/key>\n[\t ]+<string>).*?(<\/string>)/$1$version$2/;
 
open(FH, ">$INFO") or die "$0: $INFO: $!";
print FH $info;
close(FH);

To all those who said hi during WWDC...

Thank you! I meet up with a bunch of people who actively follow me on this blog and on twitter and it was great to talk to every one of you from all over the world. You guys are what made WWDC great for me this year. I myself finally got to meet up with some people who i've been talking to for a while like Scotty, Scott Stevenson, Deric Horn and all the great people in Apple Developer Technical Support. I am amazed at how many people recognized me from such small pictures on my blog/twitter. Im normally a shy person (even though I try not to be), so this was a great experience to meet people left and right. Thanks to talking to some people I got some good ideas and requests of things to cover next here on Cocoa Samurai, as always if you have any requests feel free to write in any time. I'll start work on them right after I get caught up on my homework post-WWDC :\
