Also, rather than {WRAPPER_NAME} and the rest, you could use {INFOPLIST_PATH} instead.

I found that ‘git-describe –long’ gives a perfect format for typical versioning:

my $git_description = qx{ git-describe --long };
my ( $release, $patch, $commit ) = ( $git_description =~ /([^-]+)-(\d+)-g(\w+)/ );
$release .= ".$patch" if $patch;
print "Version $release (Build: $commit)\n";

You can then tag your releases as 1.0, 2.6 etc, and the above lines will produce something like:

Version 1.0.5 (Build: 7abc23f)

I also added the following commands to the top of the script to automatically commit the current state, which then automatically bumps up the patch number… sweet!

use POSIX;
my $timestamp = strftime( "[%Y-%m-%d %H:%M:%S %z]", localtime() );
system( qw{ git-add . } );
system( "git-commit", "-a", "-m", "$timestamp automatic build commit" );

So with these changes, and an appropriate run-script build rule, every build can be re-created at the drop of a hat.

Problem solved. Thanks! (yeah there are ways to mess this up by using git-rebase etc, but this follows my development “happy path” perfectly)

I ve put this into a small ruby script which will use this number and set it as the build number.

!/usr/bin/ruby

require “rubygems” require “Plist”

pl = Plist::parse_xml(ENV['BUILT_PRODUCTS_DIR'] + “/” + ENV['WRAPPER_NAME'] + “/Contents/Info.plist”)

pl["CFBundleVersion"] = /usr/local/git/bin/git rev-list HEAD | wc -l.to_i.to_s

pl.save_plist(ENV['BUILT_PRODUCTS_DIR'] + “/” + ENV['WRAPPER_NAME'] + “/Contents/Info.plist”)

Please be aware that you have to have the Plist gem installed and that my git is in another directory when somebody wants to use it.

!/usr/bin/env python

import os from Foundation import NSMutableDictionary

version = os.popen4(“/usr/local/bin/hg log -r tip | grep ‘^changeset’ | sed s/changeset://”)[1].read() info = os.environ['BUILT_PRODUCTS_DIR']+”/”+os.environ['WRAPPER_NAME']+”/Contents/Info.plist”

plist = NSMutableDictionary.dictionaryWithContentsOfFile_(info) plist['CFBundleVersion'] = version plist.writeToFile_atomically_(info, 1)

import os from Foundation import NSMutableDictionary

plist = NSMutableDictionary.dictionaryWithContentsOfFile_(info) plist['CFBundleVersion'] = version plist.writeToFile_atomically_(info, 1)

use strict;

Get the current Mercurial revision number and 12-char truncated changeset hash

and use it to set the CFBundleVersion value e.g. 0:b1f34247e734

my $REV =/usr/local/bin/hg log -r tip | grep "^changeset"; my $INFO = “$ENV{BUILT_PRODUCTS_DIR}/$ENV{WRAPPER_NAME}/Contents/Info.plist”;

open(FH, “$INFO”) or die “$0: $INFO: $!”; my $info = join(“”, ); close(FH);
