It's encouraging that Shoes (the Ruby GUI framework) has excellent packaging functionality, but I'm concerned that it doesn't actually 'wrap' itself around created applications. Packaging for OSX outputs a shoes installer and a shoes file in a .app system. Is there any way that shoes could create a .app that contains shoes - that doesn't make you install shoes to run it?
I'm working on creating a tiny application - just a start button and a stop button for a subprocess, etc.
Hey, sorry I didn't see this question sooner.
I have good news, and I have bad news: you can absolutely do this, but there's no documentation, currently.
Hackety Hack is the biggest program that does exactly that: http://github.com/hacketyhack/hacketyhack
If you check out the build instructions, you run rake APP=/path/to/app and then rake APP=/path/to/app installer to build your own binary... but you'll have to do a bit of digging into the Rakefile to figure it out. I think that app.yaml is the only thing that's needed.
