I'd like to see a runtime dependency tree resolver in RubyGems, but if we are to include one, I would like it to resolve some complex graphs: - Cycles - Troughs - Traps A completely linear resolver I don't think can do this. You might want to read through the comments in the resolver in bundler, and it's test suite, to see what I'm talking about. > While I am on the subject, the Gemdo::Version class I'm using can > handle version constraints in these formats: > > 1.0+ (same as >= 1.0) > 1.0- (same as < 1.0) > 1.0~ (same as ~> 1.0) I like this, I would say though, adding this could have quite a marked effect on performance with the current design, as Gem::Version is created and parsed all the time. _______________________________________________ Rubygems-developers mailing list http://rubyforge.org/projects/rubygems Rubygems-developers@rubyforge.org http://rubyforge.org/mailman/listinfo/rubygems-developers
