Hi Linus,
I'll definitely move the results of the discussion into a wiki page.

can definitely pass a file name to the templating engine. There are two use
cases here:
- *Straight template-based generation*: you have a class, and an output
directory, and a template -- the template engine uses this data to determine
where what to write and where to write it. Determining the output directory
and classname is rather straight-forward:
"${outputdir}/${packageName.toPath()}/${className}.${fileExtension}"
- *Project-based generation*: you have a domain class, a project
directory, and a template -- the correct directory is determined based on
the fact that it's a domain class, it's a Grails project (or some other
framework), and we know what the project root directory is. Something like
"${projectRoot}/grails-app/domain/${packageName.toPath()}/${className}.groovy"

> In my mental model, language support = reverse engineering + code
generation, and for the time being, I'd be satisified if we just had
modifiable templates for code generation. I'm not completely dissatisfied
with reveng at the moment, there are just a few bits that are need to be
updated to properly support some features in the java language. So I'd
rather put reveng to the side for the time being and focus on code
generation. My personal feeling is that projects that are small and
well-defined are more likely to be worked on by volunteers with limited
available time and we should probably try to keep this as minimal as
possible.
