Thanks for collaborating on this. Looks good, I have a couple of suggestions to make (aside from testing) that I will propose as soon as I have some time available

How complicated would it be to have ruby as a content snap and deliver the entire hookup through an extension?

And apologies for the late response, I had an intense event and a full disconnect afterwards.

I'm sorry, but I don't understand the question. Content snap? Hookup?

What I'm already doing in a project is using this plugin in a part of its own without a source:-line, so Ruby doesn't have to be recompiled after every change in the project source code. Is that what you mean?

Please review.

Hi @paddor,

Apologies for the long delay in reviews. I'm happy to help you drive this and canonical/craft-parts#341 to completion.

I think next step is an integration test that builds a "hello world" Ruby app. You would need to add the test here and the source files for the app in a directory here. Testing this requires installing spread and running it locally with Multipass.

Alternatively, you could add the "hello world" integration test in craft-parts here (which doesn't use spread) and I can help translate it to a spread test in this PR.
