gem install qwandry

qw matrix # opens ruby's matrix class in your editor qw rails # will ask you which version of rails you want to open qw activerec 3.1 # will find the gem activerecord 3.1 and open it # You can also use Qwandry with other common languages: qw -r python numpy # opens python's numpy library qw -r perl URI # open perl's URI library qw -r node express # open express if it is installed for node
