Hello, Ive seen your new application Warehouse its really great. But as a rails developer i have a question about a feature that would like to implement myself in my app. Its about the comparison of two version (of the file) with showing the differences between them.

Can you please tell me how did you do that?

I want to build something similar to a writeboard(http://www.writeboard.com/), i used acts_as_versioned but i could not find a way to show the differences between two versions.

Thank you very much and hope to hear from you again. Bogdan Gaza - Romania

    Buy the app and find out :) Seriously though, the subversion API takes care of that for me, Warehouse just formats it to add color.

    i2 (the rails wiki) uses the html_diff library to show colorized diffs between two blobs of text.

    Not the same as what is in warehouse but you could use HTMLDiff (http://dev.rubyonrails.org/browser/tools/i2/branches/alexey/lib/diff.rb)
