I didn't know about the new "rvm v1,v2,... cmd" idiom. Really is much simpler, and certainly more elegant! I'll update the post. Thanks for the update, Wayne.

Seguin Mon, 28 Sep 2009 16:42:10 +0000 http://mynyml.com/?p=160#comment-61 Martin, Awesome writeup, thank you. I would also like to point out some relatively new features of rvm for use with testing & benchmarking. Running rake tasks across multiple versions is easy: http://rvm.beginrescueend.com/rake/ Similarly for benchmarking code: http://rvm.beginrescueend.com/benchmark/ One of the most useful not yet documented feature of rvm is: $ rvm 1.8.7,1.9.1,jruby --json rake spec This will run 'rake spec' against the three selected rubies and display a json formatted summary at the end. You can also use --yaml for a yaml formatted summary. This should be available and functioning in rvm >= 0.0.49. ~Wayne Martin,

$ rvm 1.8.7,1.9.1,jruby –json rake spec

This will run ‘rake spec’ against the three selected rubies and display a json formatted summary at the end. You can also use –yaml for a yaml formatted summary. This should be available and functioning in rvm >= 0.0.49.
