The first thing you need to know is what eRuby is. eRuby is simply a way of embedding Ruby code inside an HTML document. It is used just like ASP, JSP, and PHP, but it gives you all the power of Ruby instead. There are several different implementations of eRuby, including eruby and erb. This tutorial is going to discuss eruby.

There are three ways to embed Ruby inside an HTML document:

<% ruby code %>
<%= ruby expression %>
<%# ruby code %>

If you are familiar with ASP, JSP, or PHP, this should be very familiar to you (except for maybe that last one). The following examples will be run through the eruby program directly. Here's an example of using the first form:

This is embedded <% bleh = "Ruby"; print "#{bleh}!" %>

This statement would produce: This is embedded Ruby!Here's an example of using the second form:

<%bleh = "Ruby"%>This is embedded <%=bleh%>!

The output is the same as before. The last form of embedding Ruby is the same as the first. Pretty simple, huh? eRuby really isn't complicated, so long as you already know Ruby ;] OK, so you can run this stuff through the eruby program, but how do you get a webserver to run this? Simple. I'm going to show you how to use eruby with Apache.The first thing you need to do is copy the eruby program itself into your cgi-bin directory. Then you need to edit your httpd.conf file.

Add these two lines:
AddType application/x-httpd-eruby .rhtmlAction application/x-httpd-eruby /cgi-bin/eruby
Now, whenever you want to use an HTML file with embedded Ruby, just rename the file with a .rhtml extension and you're ready to go. You can also add or replace your DirectoryIndex directive so that index.rhtml is searched for.

For example:
DirectoryIndex index.html index.shtml index.rhtml
Pretty easy. And, if you're using Apache and want faster access, you can always download and install mod_ruby.Well, that's it for now. For more information about eRuby, check out the Ruby documentation (that's where I got this info).

this does not work in apache for xp, what do you mean copy the eruby program itself into your cgi-bin directory?? its a directory structure

The Ruby Way on Wed 27th Aug 6pm
I've recently come back to OSIX and taken all the challenges again. This next time around, however, I'm using Ruby to tackle them. I will admit that my old C versions of some solutions ran faster (especially the brute force ones), but coding the Ruby ve
Ruby on Rails on Tue 10th Oct 9am
I installed ruby and wrote my first ruby on rails web application. It was quite an enjoyable experience. Certainly more fun than asp.net (which is bloody unproductive) I suggested we knock some internal application up in it for my company to have ap
