[gentoo-dev] RFC: Add RUBY_TARGETS to USE_EXPAND

[gentoo-dev] RFC: Add RUBY_TARGETS to USE_EXPAND

Hey,

I would like to propose the addition of a new USE_EXPAND variable.

The Ruby team is currently working on a new version of ruby.eclass with
proper support for packages installed for multiple versions of ruby.

RUBY_TARGETS contains a list of ruby implementations and versions to
install a package for, like this:

[ebuild     U ] dev-ruby/actionpack-2.3.2-r1 [2.3.2] USE="-doc -test%"
RUBY_TARGETS="ruby18* ruby19* -jruby%" 746 kB [0=>1]

In that example, actionpack would install for Ruby 1.8 and 1.9. USE
dependencies are then used to ensure all dependencies are built
at least for 1.8 and 1.9 as well.

Any comments or questions?

Thanks, Alex

 Python has to do the same for 2.x and 3 versions...wouldn't it be nice
to have the same solution for both languages?

It might be nice, /eventually/.
As far as I can see, the proposed Python solution is just a concept,
where we already have near-beta eclasses that we *really* want to deploy
this year as they block the unmasking of Ruby 1.9.
Additionally, there are some really nasty things about the current
ruby.eclass (prepall override) and incompatibilities with RubyGems that
should be resolved rather sooner than later.
