A few days ago after seeing this tweet, I’ve decided to migrate the gem rubygems-isit19 to jruby. Thanks to this, when you install another gem you’ll be able to read about compability of this gem with jruby, the information is fetched from isitjruby.com website.
Once you have installed the gem you will have two main features, it’s easier if I just show you. First the messages when you install gems:
$ jgem install daemons daemons 1.0.10 probably might not work, blaxter says 1.0 fails Update http://isitjruby.com/daemons with your experiences! Successfully installed daemons-1.0.10 1 gem installed $ jgem install cucumber cucumber 0.3.97 might work, 100% say 0.3.11.3 works on jruby Update http://isitjruby.com/cucumber with your experiences! Successfully installed cucumber-0.3.97 1 gem installed $ jgem install faker faker 0.3.1 is 100% verified jruby Update http://isitjruby.com/faker with your experiences! Successfully installed faker-0.3.1 1 gem installed
And also we have an explicit gem command:
$ jgem isitjruby faker faker 0.3.1: http://isitjruby.com/faker Blaxter says 0.3.1 works on GNU/Linux it works perfectly, and it passes all test. $ jgem isitjruby daemons daemons 1.0.10: http://isitjruby.com/daemons blaxter says 1.0 fails on GNU/Linux Daemons use fork, jruby doesn't support fork, so it doesn't work and never will
And that’s it. The code is on github be free of fork me or open any issues. The important thing is populate with relevant information isitjruby.com for benefit of all jruby community. Oh I forgot to tell you how to install it, very easy, I’ve uploaded the gem to gemcutter so you can install it with something like
$ jgem install rubygems-isitjruby -s http://gemcutter.org
It’s also in github, but I think (and I hope) gemcutter will be the next rubyforge, so better gemcutter .
