| I have proven to my own satisfaction that on 10.4.9 with the Developer tools installed, a ruby program can be used as a postflight script. I made an installer that does nothing special (installs a copy of SimpleText to /) and added a postflight script as follows:
Here's the script file |
Attachment:
postflight
Description: Binary data
Here's the contents of the script file: #!/usr/bin/ruby
puts "Hello world! My arguments are #{ARGV}!"
The file is placed at this location Foo.pkg/Contents/Resources/postflight
Note that the file has NO extension. The Finder will sometimes trick you about this, so check ls -al Foo.pkg/Contents/Resources/postflight which produces: -rwxrwxr-x 1 root admin 63 May 4 12:07 Foo.pkg/Contents/Resources/postflight*
Note the owner and permissions are important. That "x" bit must be there!
Note there's no special reason you shouldn't just do the following every time you build your installer: chmod 755 Foo.pkg/Contents/Resources/postflight chown root:admin Foo.pkg/Contents/Resources/postflight
And here's the log showing it executed: May 4 12:23:53 bcPie-apple-com : run postflight script for Foo May 4 12:23:53 bcPie-apple-com : postflight[545]: Hello world! My arguments are /Users/bc/Desktop/Foo.pkg///! May 4 12:23:53 bcPie-apple-com : postflight[545]: May 4 12:23:53 bcPie-apple-com : Removing temporary directory "/private/tmp/Foo.pkg.533CO936j" ....
OK, so ruby doesn't do the prettiest job echoing the command line arguments, but there they are.
Note that my lunchtime isn't long enough to try older versions of 10.x. I also don't know the history of ruby on Mac OS X. If you are intending to ship your installer on old versions of Mac OS X, you'd best find out. If there's no ruby on the user's system, your script won't run very well.
