I too want this kind of functionality. I have a test integration
framework that brings together several of our in-house tools and for the
moment I'm calling rakefiles in a shell, which considering all my code
is in Ruby is a bit of a shame.
I guess the only thing that needs to be changed to allow this more
easily, is the command line option handling.
There should be a way to pass all the options to the Application object
without using the command line syntax.
One solution is to be able to pass an OpenStruct to initialize and check
for nil in Application#handle_options (but I don't like it very much
since it would mean you have to know all options by heart and the
interface is defined in Application. It's not that it doesn't work, it's
that it is impractical when you want to provide default values for some
paramaters and for the documentation)
Another would be to skip the ostruct and go directly for the
:symbol=>value hash so used in Rails.
A third option would be to wrap this ostruct/hash in a configuration
object with accessor methods. This gives us an interface separately from
the Application which will look better in RDoc :) ).
Anyway, the code in
if __FILE__ == $0 then
would then do a few more things. Basically:
