NAME
    HTML::Email::Obfuscate - Obfuscated HTML email addresses that look
    normal

DESCRIPTION
    *"Don't put emails directly on the page, they will be scraped"*

    Stuff that, I'm sick of looking at "bob at smith dot com". Why can't we
    just write emails in a way that looks normal to people, but is very,
    very difficult to scrape off. Most email scrapers only use very very
    simple parsing methods. And it isn't as if it is hard to just do.

      # Before we search for email addresses...
      $page =~ s/\s+at\s+/@/g;
      $page =~ s/\s+dot\s+/./g;

    This is an arms war dammit, and I want nukes!

  About this Module
    This module was written during OSDC/YAPC.AU to demonstrate how quick and
    easy it is to write a basic module and put it on CPAN. The code was
    written in about 40 minutes, the documentation was added during a break
    period before drinks and dinner, and the packing and test files were
    added during the python keynote (significant whitespace... ew...).

  How this works
    This module starts by applying a fairly basic set of character escapes
    to avoid the most basic scrapers, and then layers more and more crap on
    randomly, so that any scraper will need to implement more and more of a
    full web browser, while keeping the email looking "normal" to anyone
    browsing.

    I've only scraped the surface of what we can achieve, and I'll leave it
    to others to submit patches to improve it from here on.

  Using HTML::Email::Obfuscate
    This is a pretty simple module.

    First, create an obfuscator object. This is just a simple object that
    holds some preferences about how extreme you want to be about the
    obfuscation.

      # Create a default obfuscation object
      my $Email = HTML::Email::Obfuscate->new;

    Now to turn a normal email string into an obfuscated and fully escaped
    HTML one, just provide it to the escape_html method.

      # Obfuscate my email address
      my $html = $Email->escape_html( 'cpan@ali.as' );

    And we get something like this

      ***Example here once I get a chance to run it***

    The defaults are fairly insane, so for people that just want veeeery
    simple escaping, we'll provide a lite version.

      # Create a "lite" obfuscator
      my $Email = HTML::Email::Obfuscate->new( lite => 1 );
  
      # Access the lite escape method directly, regardless of the
      # obfuscator's constructor params.
      my $html = $Email->escape_html_lite( 'cpan@ali.as' );

    For the more serious people, we can also add some more extreme measures
    that are probably not going to be compatible with everything, such as
    JavaScript. :/

      # Allow the obfuscator to use JavaScript
      my $Email = HTML::Email::Obfuscator->new( javascript => 1 );

    Best not to use that unless you have a JavaScript-capable browser.

    I think that just about covers it, and my 7 minute lightning talk is
    probably almost up.

METHODS
  new $param => $value [, ... ]
    The "new" constructor creates a new obfuscation object, which use can
    then use to obfuscate as many email addresses as you like, at whatever
    severity you want it to be done.

    It takes two optional parameters.

    If you set the 'javascript' param, the obfuscator will add JavaScript
    obfuscation (possibly, and randomly) to the mix of obfuscation routines.

    If you set the 'lite' param, the obfuscator will only use the most basic
    form of escaping, which will only fool scanner that don't do HTML entity
    decoding. Setting 'lite' implies that JavaScript should not be used,
    even if you explicitly try to turn it on.

    Returns a new "HTML::Email::Obfuscate" object.

  escape_html_lite $email
    On an otherwise normal obfuscator, the "escape_html_lite" method
    provides direct access to the lite method for obfuscating emails.

    Returns a HTML string, or "undef" if passed no params, or and undefined
    param.

  escape_html $email
    The "escape_html" method obfuscates an email according to the params
    provided to the constructor.

    Returns a HTML string, or "undef" if passed no params, or and undefined
    param.

TO DO
    OK, other than compile testing, I admit that I haven't really done
    anything significant in the way of testing. I mean, there was SUCH an
    interesting python talk on, and how on earth do you test something that
    has randomised output. :/

    So yeah, it would be nice to write some better tests.
