Question

As you probably know, to do a PHP script, you could just do..

<?php
    Code..
?>

..and it would run the PHP code, as long as you have the PHP module loaded.

Is there a module that would allow you to do something similar with Ruby? Something like this would be nice:

<?ruby
    Code..
?>

Answer 1

Ruby’s equivalent would be one of Erb, Erubis or HAML.

Erb comes with Ruby. Erubis is a compiled interpreter for Erb templates. They use <%= ... > to mark where Ruby variables should be inserted. You can also include Ruby control structures easily using <%- ... >, to allow looping, creating of variables, etc.

HAML is similar to those, but acts much like a HTML-shorthand. I prefer HAML for my own projects.
