Hi,

I'm just starting to learn ruby and would like to know the best
library to
use to create a static html page from a cron job. The page will
contain the
results of a database query displayed as an html table. Some sort of
template package might be best. I already have dbi working to do
the query.

Any advice would be appreciated.

Hey there-
     Here is an example of generating html with erb in the stdlib docs:

Ruby in HTML
ERB is often used in .rhtml files (HTML with embedded Ruby). Notice
the need in this example to provide a special binding when the
template is run, so that the instance variables in the Product object
can be resolved.

   require "erb"

   # Build template data class.
   class Product
     def initialize( code, name, desc, cost )
       @code = code
       @name = name
       @desc = desc
       @cost = cost

       @features =
     end

     def add_feature( feature )
       @features << feature
     end

     # Support templating of member data.
     def get_binding
       binding
     end

     # ...
   end

   # Create template.
   template = %{
     <html>
       <head><title>Ruby Toys -- <%= @name %></title></head>
       <body>

         <h1><%= @name %> (<%= @code %>)</h1>
         <p><%= @desc %></p>

         <ul>
           <% @features.each do |f| %>
             <li><b><%= f %></b></li>
           <% end %>
         </ul>

         <p>
           <% if @cost < 10 %>
             <b>Only <%= @cost %>!!!</b>
           <% else %>
              Call for a price, today!
           <% end %>
         </p>

       </body>
     </html>
   }.gsub(/^ /, '')

   rhtml = ERB.new(template)

   # Set up template data.
   toy = Product.new( "TZ-1002",
                      "Rubysapien",
                      "Geek's Best Friend! Responds to Ruby
commands...",
                      999.95 )
   toy.add_feature("Listens for verbal commands in the Ruby language!")
   toy.add_feature("Ignores Perl, Java, and all C variants.")
   toy.add_feature("Karate-Chop Action!!!")
   toy.add_feature("Matz signature on left leg.")
   toy.add_feature("Gem studded eyes... Rubies, of course!")

   # Produce result.
   rhtml.run(toy.get_binding)
Generates (some blank lines removed):

    <html>
      <head><title>Ruby Toys -- Rubysapien</title></head>
      <body>

        <h1>Rubysapien (TZ-1002)</h1>
        <p>Geek's Best Friend! Responds to Ruby commands...</p>

        <ul>
            <li><b>Listens for verbal commands in the Ruby language!</

</li>

            <li><b>Ignores Perl, Java, and all C variants.</b></li>
            <li><b>Karate-Chop Action!!!</b></li>
            <li><b>Matz signature on left leg.</b></li>
            <li><b>Gem studded eyes... Rubies, of course!</b></li>
        </ul>

        <p>
             Call for a price, today!
        </p>

      </body>
    </html>
