Freightrain is a MVVM (model/view/viewmodel) framework for developing desktop applications in ruby

If you plan to use the gtk+ extensions (the best supported at the moment), you should also have the gtk2 gem installed. Before installing the gem you should also have the dev library for pango, cairo, glib and gtk2 installed. On ubuntu you can get all you need with:

sudo apt-get install libgtk2.0-dev libruby1.9 ruby1.9-dev

gem install gtk2

When you’re done with that you can install freightrain with:

gem install freightrain

gem install freightrain

gem install gtk2

ftrain app testapp

cd testapp

ruby testapp.rb

after that, you should see an empty window.

There are small examples in the /examples repository folder. There is also a tutorial (under construction, by Eric Cunningham) here : sites.google.com/site/freightrainlib

An up to date larger example : github.com/bolthar/intersect

After installing the freightrain gem using the above instructions, to get a working stub open a terminal and type in: ftrain app my_app this will create a new directory my_app containing the application stub. To run the stub application, cd into the directory and type: ruby my_app.rb this should pop up an empty window with the title ‘my_app’.
