What about _why's Markaby:
http://markaby.rubyforge.org/
Phil
the only reason i haven't jumped into rails head first is the forms
class... regex, js and server validation, simple js commands
(background color, etc...), length, width and a ton more.
it will be tough to let go - since so much of good web development is
tied up in forms generation and validation.
decisions, decisions.
On a similar note ....
Is there a class to parse a form and send the results in email? I am
looking for something as "plug and play" as possible.
All comments welcome

NAME
xx - twice as dirty
SYNOPSIS
> gem install "double x"
require "xx"
include XX::XHTML
doc = xhtml_{
html_{
head_{ title_{ " go xx! " } }
body_{ " one more and it would be illegal " }
}
}
URI
http://rubyforge.org/frs/?group_id=1024
DESCRIPTION
xx is a library designed to extend ruby objects with html, xhtml, and xml
generation methods. the syntax provided by xx aims to make the generation of
xml or xhtml as clean looking and natural as ruby it self.
the approach taken, that of extending objects, allows natural document
generation while preserving access to instance data. in essence it provides
ruby objects (including the top level 'main' object) an intuitive means to
generate various markup views of their data in a way that is correct and
elegant.
xx is brought to you by the good folks at http://eparklabs.com.

HISTORY
0.1.0:
- added the "g_" method, which generates any tag
^
g_("anytag", "key" => "value"){ b_{ "bold" } }
- added at_ and att_ methods to parse yaml and k=v strings as hashes.
at_("src : image.jpg, width : 100%")
#=> {"src"=>"image.jpg", "width"=> "100%"}
0.0.0:
- initial version

If very desperate, you can put a YAML dump of the form data in an e-mail.
Personally, I don't think I'd use such a magic solution - I prefer a good HTTP
request parser and a good mailer as separate components, than a half-baked
mix and match of both.
David Vallner
I'd like to play around with this, as an alternative to Amrita.
But the tests are broken because here is no sample dir installed with
the gem. Is this fixable with gems?

The parser is no issue that would be pretty much unique to the form and I
have lots of experience with parser code. What I really need is a mailer
that will take SMTP host name or IP and the parsed form info and send it of
to the correct (and sometimes different) email addy.
Any suggestions?

hmmm. i'm not sure what to do - but i'm open to suggestion! maybe i should
just reloate the samples directory into the test directory?
for now you can just grab the tarball - sorry for inconvenience.
cheers.

Net::SMTP? Not really a mailer though. I know Rails includes a Mailer
component. If I have my facts right, it uses a library called TMail to create
the mail messages... The Net::SMTP documentation also recommends RubyMail as
an option for mail generation.
So, you get the data from the form, compose the mail object to send using
TMail or RubyMail, then use Net::SMTP to send the mail object. If what you're
doing is simple enough to go without a full blown webapp framework, this
should work perfectly.

Tnx! tests pass now.
However, the example at the end of xx.rb seems to be failing:
$ ruby lib/xx.rb

Here is a little snippet that might help for sending emails from a ruby script:
require 'net/smtp'
def send_mail(to, from, subject, body)
msgstr = <<EOM
From: #{from}
To: #{to)
Subject: #{ subject }
MIME-Version: 1.0
Content-Type: text/html;
<html>
<style type='text/css'>
#m_b div { border: 1px solid #aaa; }
</style>
<body>
The following email is about...:<br />
<hr />
<div id='m_b'>
<div>#{ body }</div></div>
</body></html>
EOM
Net::SMTP.start('mail.example.com', 25, 'mail.com', 'username', 'password', :login) do |smtp|
smtp.send_message msgstr, "#{from}", "#{to}"
end
puts "Mail sent."
puts "*"*30
puts msgstr
end
