Questions tagged [haml]

HAML is a markup language that’s used to cleanly and simply describe the HTML of any web document without the use of inline code. It can be used as a standalone HTML generation tool or as a template rendering engine in a web framework such as Ruby on Rails or Ramaze. HAML templates are pre-compiled into plain HTML templates which is consumed by a client's web browser to render information sent by the server as a HTML web page.

HAML (HTML Abstraction Markup Language) is an indentation based, terse page description markup. It features among other things autoclosing of tags and convenient shorthands to set class and id attributes.

Example

page and its conversion :

erb 

<div id='content'>
  <div class='left column'>
    <h2>Welcome to our site!</h2>
    <p><%= print_information %></p>
  </div>
  <div class="right column">
    <%= render :partial => "sidebar" %>
  </div>
</div>

HAML

#content
  .left.column
    %h2 Welcome to our site!
    %p= print_information
  .right.column
    = render :partial => "sidebar"
