How do I write those cool command line code generators (rails, sproutcore, webgen)

Question

I've grokked the code for all the aforementioned apps and I still can't find a straightforward way to create a static directory structure from a single command.

Check out rubigen. You can also view a presentation by dr nic.

Answer 2

So what you want is to able to issue a command that will generate an entire directory tree?

cp -r <template> <destination>

Or am I misunderstanding? If you want to generate a consistent directory structure, your best bet is to simply copy it from a template. Fast, easy, done.
