tagz.rb generates html, xml, or any sgml variant like a small ninja running across the backs of a herd of giraffes swatting of heads like a mark-up weedwacker.

NAME

  tagz.rb

SYNOPSIS

  require Tagz

  include Tagz.globally

  a_(:href => "/foo"){ "bar" }  #=>  <a href="/foo">bar</a> 

DESCRIPTION

  tagz.rb is generates html, xml, or any sgml variant like a small ninja
  running across the backs of a herd of giraffes swatting of heads like a
  mark-up weedwacker.  weighing in at less than 300 lines of code tagz.rb adds
  an html/xml/sgml syntax to ruby that is both unobtrusive, safe, and available
  globally to objects without the need for any builder or superfluous objects.
  tagz.rb is designed for applications that generate html to be able to do so
  easily in any context without heavyweight syntax or scoping issues, like a
  ninja sword through butter.

FEATURES

  - use as a library or mixin

  - simple, clean and consistent mark-up that is easy to visually
    distinguish from other ruby methods

  - auto-compatibility with rails/actionview

  - ability to independently open and close tagz in markup

  - intelligent auto-escaping of both attributes and content for both html
    and xml

  - validate your html/xml with 'ruby -c' syntax check

  - generally bitchin

  - no lame method_missing approach that prevents tagz like 'type' from being
    generated

RAILS
  
  in config/environment.rb

    require 'tagz'

  in a helper

      ul_(:class => 'users'){
        @users.each{|user| li_{ user }}
      }
    end

  in a view

    table_{ 
      rows.each do |row|
        tr_{
          row.each do |cell|
            td_{ cell }
          end
        }
      end
    }

  in a controller

    def ajax_responder
      text =
        tagz{
          table_{ 
            rows.each do |row|
              tr_{
                row.each do |cell|
                  td_{ cell }
                end
              }

HISTORY
  7.0.0
    - * IMPORTANT * NOT BACKWARD COMPATIBLE (thus version bump)
    the tagz functionality itself has not changed, but the defaults for
    excaping have!  now tagz will escape attributes, but NOT content, in the
    default mode.  you can easily configure something else with

      Tagz.escape!(:content => true, :attributes => true)

    which would be like saying

      Tagz.xml_mode!

    or

      Tagz.escape!(:content => false, :attributes => true)

    which would be like saying

      Tagz.html_mode!

    to repeat, the default is 'Tagz.html_mode!'

  6.0.0 
    - reorganize lib to avoid dumping a few constants into the includee - aka
    don't absolutely minimize namespace pollution. there is now reason to
    thing this version shouldn't be backwards compat - i bumped the version
    just in case

  5.1.0
    - attribute/content auto-escaping can be turned off with

        Tagz.i_know_what_the_hell_i_am_doing!

      and turned back on with

        Tagz.i_do_not_know_what_the_hell_i_am_doing!

      attribute and content escaping can be configured individually too. see
      tests for examples


      thanks Dan Fitzpatrick

    - << and concat escape (if configured) while puts and push and write do not

      thanks JoelVanderWerf

  5.0.0
    - introduce better escaping for attributes using xchar.rb approach
    - indroduce smart escaping for content
    - make Tagz.globally kick ass more hard
    - note that this version is not backward compatibile if you were relying
      on tagz never escaping any content should be an ok upgrade for most
      applications

  4.6.0
    - fix a bug with self closing tagz that had crept in 1.0.0 -> 4.2.0.  thx
      jeremy hinegardner

    - added tests from 1.0.0 back into svn

  4.4.0
    - remove dependancy on cgi lib, tagz is now completely standalone

  4.3.0
    - detect rails and auto-include into ActionController::Base and include
      globally into ActionView::Base

  4.2.0
    - general lib cleanup
    - introduction of dual-mixin technique (Tagz.globally)
    - few small bug fixes
    - ninja tales
