Converting all ERb views to Haml

divoxx (Rodrigo Kochenburger) — Thu, 01 May 2008 23:27:09 GMT

A little script to convert all your .erb views to .haml using html2haml, which is included with Haml installation.
Just drop this in your rails root folder and run it.



class ToHaml

  def initialize(path)

    @path = path

  end

  

  def convert!

    Dir["#{@path}/**/*.erb"].each do |file|

      `html2haml -rx #{file} #{file.gsub(/\.erb$/, '.haml')}`

    end

  end

end



path = File.join(File.dirname(__FILE__), 'app', 'views')

ToHaml.new(path).convert!

abbr formatting

haml (easily transformed to css) snippet to format abbrs in a proper manner - you can still type them in ALL CAPS, but they will be displayed in Titlecase and small-caps. If you're using this, you're probably also using a custom face via @font-face, so you might want to explicitly declare the small-caps and lowercase variants of the typeface - the browser often fucks up auto-small-caps.

also, not tested in internet explorer. nothing I write is.



abbr

  :display inline-block

  :text-transform lowercase

  :font-variant small-caps

  

  &:first-letter

    :text-transform uppercase

Convert XML to Haml

This Ruby code converts a simple XML document into HAML.



require 'rexml/document'

include REXML



fruit = "tasty"



doc_fruit = Document.new(fruit)



def xml2haml(nodex, indent ='')



  nodex.elements.each do |node|



    attributex = ' '

    buffer = indent + '%' + node.name



    if node.attributes.size > 0 then

      alist = Array.new(node.attributes.size)

      i = 0

      node.attributes.each { |x, y|

        alist[i] = " :#{x} => '#{y}'"  

        i += 1

      }

      attributex = '{' + alist.join(",")  + '} ' 

    end

 

    buffer +=  attributex + node.text if not node.text.nil?  

    puts buffer

    xml2haml(node, indent + '  ')

  end

end



xml2haml(doc_fruit)

output:



%fruit

  %apple{ :month => 'august', :country => 'france'} tasty

    %gdelicious

  %pear

Running Haml stand-alone

jrobertson (James Robertson) — Wed, 14 Nov 2007 12:12:14 GMT

This Ruby code converts HAML to XHTML. code based on the example given at 'A HAML Server for Web Designers' http://urltea.com/23j8 [wiseheartdesign.com].



require 'rubygems'

require 'haml'



def parse_haml(string)

  engine = Haml::Engine.new(string)

  engine.render

end



parse_haml("#hello")

Note: The above code worked on Ubuntu 7.10, and on Gentoo I declared require 'haml/engine' as an alternative to requiring 'rubygems' and 'haml'.
