Bug 483360 – app-text/docbook-xsl-stylesheets with USE="ruby" should make use of RUBY_TARGETS

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Manuel Rüger (RETIRED) 2013-09-02 09:14:25 UTC]

Currently this pulls in ruby20 because it depends on dev-lang/ruby directly. 

Either we should drop the useflag or add some ruby-eclass stuff to it, so it depends on a sane slot based on RUBY_TARGETS.

Another possibility is masking the ruby useflags.

Deptree. 

Or we could add a virtual/any-ruby which is satisfied by || ( any-existing-ruby-interpreter ) and make it depend on this.

docbook-xsl-stylesheets-1.78.0.ebuild.patch

I'm not sure if this will work or not?

Can't do that since we can't guarantee compatibility between versions. Each package needs to express its compatibility in some way.

I think we should create a simple eclass that, for now, just manages the ruby dependencies based on USE_RUBY and RUBY_OPTIONAL.

We can extend it later with proper support for compiling bindings.

app-text/xmlformat is another candidate for this. Right now I've solved this same problem there by depending on || ( ruby:1.9 ruby:2.0 ).

Thanks, I added a -r1 with the same fix.

Yeah the eclass approach will be of course the better way to solve this.
