I am _woefully_ behind on getting a release out the door because I want to 
have some documentation going out with it, and I just haven't found the 
extra couple hours a day to finish writing it.

In a nutshell, Iowa represents content or pieces of content as objects.  
It provides a seperation of content from code and an easy to use 
templating system.  The content is almost completely plain HTML, with just 
a bit of special markup via specific tags.

The @ character indicates that what follows is a method to execute.  The 
@foo is replaced by the to_s'd result of executing the method.

I'll just draw you a quick example:

A complete Iowa application will have, at a minimum, 4 files, though I 
have developed a framework within Iowa to let one use it to create simple 
1-page dynamic content or to tie pieces of the application (specific 
objects) to certain URLs.  Using those capabilities adds a few more files.

So, simple example:


example.rb:
-----
#!/usr/local/bin/ruby
require 'iowa'
require 'iowa/dbpool' #my database pool

class MySession < Iowa::Session

  attr_reader :foo, :bar #you can use these to deliver per/session
                         #data for components to use
  def initialize(*args)
    #####
    #// Setup useful data sets for the components to use here.
    #####
    super
  end
end

class MyApplication < Iowa::Application
  attr_accessor :dbpool #per application items, such as the database pool

        def initialize(*args)
                #####
                #// Initialize the application wide db connection pool.
                ###
                @dbpool = Iowa::DbPool.new('Mysql','localhost','foo','bar','whatever',2)
                super
        end
end

Iowa.startDaemon('example.cnf')
Iowa.run
-----

example.cnf
-----
socket:
  hostname: localhost
  port: 15013
logging:
  basedir: /usr/local/htdocs/enigo.com/log
  minlevel: 0
  maxsize: 10000000
  maxage: 86400
-----

The config file is in YAML format, and is pretty self explanatory, I 
think.  Iowa supports communication with the application process via 
either TCP socket or Unix domain socket.

The example.rb stub gets executed to start the Iowa application process.

There always has to be a Main.html.  If using the ability to map URLs to 
objects, Main.html (and the code file for it, Main.iwa) will be two small 
little files that together provide the dispatcher to pass the action on to 
the right object.  If using the simpler model, then the Main object is 
where your app must start interacting with the world.  Code and content 
can be included in seperate sections of th same file, or in different 
files.

    end

    end

    def addNumber
      @sum += @newnumber.to_i
    end
  end

    item = number
    list = numbers
  }

That's it.  You just write your content directly, making use of The @ 
notation to invoke methods, using special tags (like <repeat> and <if>), 
or adding the 'oid=' attribute to another tag to indicate to Iowa that 
this tag does someting dynamic and to Iowa needs to handle it.

And you write your code in regular Ruby.

The <% %> and <? ?> Notation is to seperate code from bindings, since
those still currently must reside in the same file (though I will probably
make it possible to seperate them into their own files soon and thus
completely do away with <% %> if wanted).  Bindings can be used for a lot 
of different things.  In this example, it creates a list that the <repeat> 
and the <ul> can iterate over, getting its values from numbers() and 
putting them, in turn, into @number.

I use it for a LOT of production web work ranging from just a few simple 
dyanmic pages to an application with 10k lines of HTML and 7k lines of 
code.  It makes the work SO much easier because it provides the tools that 
I need to do everything that I want, and it otherwise stays out of my way.

I need to save this post.  I can use it in the documentation, I think.

Thanks.  If you have any questions, don't hesitate to ask.
