Zeus support

[asok]

#48
Zeus support for rinari-web-server, rinari-console and rinari-rake.

The biggest surgory was made to rinari-web-server that is instead of calling ruby-compilation-run it is calling ruby-compilation-do. So it does not run ruby process but rather rails or zeus processes with correct arguments.
Maybe I'm wrong but all of the files in the scripts directory are executables with shebang pointing to /usr/bid/env ruby. If yes then we can do get away with this.

rinari-script would take similar approach as rinari-web-server. I can take a stub on that later.

I think I have a neater integration mechanism figured out, and I've been reorganising ruby-compilation.el over the last few days ready to insert it. As a result, this pull request doesn't apply right now, but it's been helpful to see your approach. Please bear with me, and I hope to have something ready to share soon. :-)

Zeus looks awesome and rinari is already awesome :), I am interested in using Zeus with rinari. @purcell do you have some update on this?

[purcell]

Nope, I haven't had more time to work on it, and I didn't want to just hack in support because it affects both rinari and ruby-compilation.

[luisalima]

Oh ok! Thanks anyway, I'll be eagerly waiting :)

+1 I would love to see rinari be zeus aware.

Hey @purcell, I was wondering if you had any tips for making ruby-compilation work with zeus with or without Rinari. I hacked something together with M-x compile for now, but the less Elisp I'm responsible for, the better!

[jmdeldin]

In case someone runs across this later... rspec-mode will use Zeus if you set rspec-use-zeus-when-possible.

[purcell]

This would be easy if zeus were a drop-in replacement for the Rails script. IIRC, though, when I played with this a while ago, zeus would ignore the "environment" argument for zeus console -- this mismatch means potentially coding around a bunch of special cases. Maybe things are different now.

[jmdeldin]

Ah, good point about running a test-env console. Looks like there's no way around it with zeus unless you add a new command. I don't think it's worth worrying about -- rspec-mode fills the testing gap for me right now. Thanks for all your work!
