Using mod ruby and eRuby

From OCS Support Wiki

On all of our shared hosting servers, mod_ruby and eruby are installed. mod_ruby lets you run your Ruby applications faster than traditional CGI scripts, and eruby allows you to use Ruby inline with your HTML code, much like you would with PHP.

[edit] mod_ruby

There are two basic methods to use mod_ruby. First, you can simply name your file with the .rbx extension. This will tell Apache to run your file as a Ruby script. You can also make a folder called ruby in your public_html folder and put any files you wish to run as Ruby scripts there.

[edit] eruby

Just like with mod_ruby, there are two methods to make a file be parsed by eruby. You can name the file with the .rhtml extension, or you can make a folder called eruby in the public_html folder and use eruby on any file in that folder.

With eruby, start your ruby code with <% in your HTML file, then end it with %>. You can enter eruby mode multiple times, and can even stay in it for the entire file if you like, again, just like PHP.
