NAME

Template::Plugin::Haml - Haml plugin for Template Toolkit

VERSION

version 0.1.2

SYNOPSIS

        [%- USE Haml -%]
        [%- FILTER haml -%]
        %p Hello World
        [%- END -%]

        <p>Hello World</p>

DESCRIPTION

A thin wrapper around Text::Haml when you load the plugin it creates a filter called haml that you can use in a normal way. A full description of the Haml language can be found on the haml site. Haml is a terse and whitespace sensitive html, xhtml, and xml templating system. Compared to Template Toolkit however it is relatively limited in what you can do. It by itself contains no includes, conditionals, or loop constructs. So I've combined it here with TT to make writing those kinds of templates with even less code easier.

EXAMPLE

input template

wrapper.tt

        !!! 5
        %html
        [% content %]

hello.tt

        [%- message='Hello World' %]
        [%- USE Haml -%]
        [%- WRAPPER wrapper.tt | haml -%]
        [%- FILTER haml -%]
         %head
          %meta{:charset => "utf-8"}
          %title hello
         %body
          %p [% message %]
          %ul
          [%- total=0; WHILE total < 5 %]
           %li [% total=total+1 %][% total %]
          [%- END -%]
        [%- END -%]

I'd like to draw some attention to the while loop here you have to have the -'s in just the right spots to make it work because of Haml's whitespace sensitivity.

It's also important to note that <tags> will be </closed> in the templates they're in. If you used PROCESS instead of WRAPPER above your template would be output like

        ...
        <html></html>
         <head>
        ...

instead of...

Output

        <!DOCTYPE html>
        <html>
         <head>
          <meta charset='utf-8' />
          <title>hello</title>
         </head>
         <body>
          <p>hello world</p>
          <ul>
           <li>1</li>
           <li>2</li>
           <li>3</li>
           <li>4</li>
           <li>5</li>
          </ul>
         </body>
        </html>
