Puppet

The problem here is that we can map a resource title to different namevars (with the title_pattern method) but puppet has no way to do a backward mapping and looking at the diffs that you attached this seems to be the problem here.

Dan Bode did some work on this topic see the discussion here and an experimental patchset which introduces a namevar_join method here but I guess none of it made it into core. There are still some other problems when it comes to multiple namevars (#5605),

Added Dan Bode as a watcher.

Max,

Thanks for working on this! I will try out the patch this weekend.

I’m using composite name vars to install RVM with puppet. You can see the module here: [[https://github.com/blt04/puppet-rvm]]

Specifically, for installing gems and gemsets in a specific Ruby version in RVM: [[https://github.com/blt04/puppet-rvm/blob/master/lib/puppet/type/rvm_gem.rb]] [[https://github.com/blt04/puppet-rvm/blob/master/lib/puppet/type/rvm_gemset.rb]]

Composite namevars allow me to use syntax like:

rvm_gem {
  'ruby-1.9.2-p290/bundler':
    ensure => '1.0.18',
    require => Rvm_gemset['ruby-1.9.2-p290@myproject'];
}

where ruby-1.9.2-p290 is the name var :ruby_version, and bundler is the namevar :name.

Very cool use of composite namevars. Have you had a chance to check out the patch? I’d like to get it into core soon if it helped you out.

Max, I’m sorry it took so long to respond. Your patch did fix the problem I was having. It looks like the patch is a good fix for this ticket. Thank you!
