How to comment out a line in HAMLC comment

Wondering how to comment out one line in HAMLC. I Tried 

# this is commented out

But it doesn't work. It creates a <div> this is commented out </div> Can't find many resources on HAMLC.

Knowing how to comment out multi-line would also be appreciated.

Solution

  • This is from the Haml documentation for comments:

    Comments

    Haml supports two sorts of comments: those that show up in the HTML output and those that don’t.

    HTML Comments: /

    The forward slash character, when placed at the beginning of a line, wraps all text after it in an HTML comment. For example:

    %peanutbutterjelly
  / This is the peanutbutterjelly element
  I like sandwiches!

    is compiled to:

    <peanutbutterjelly>
  <!-- This is the peanutbutterjelly element -->
  I like sandwiches!
</peanutbutterjelly>

    The forward slash can also wrap indented sections of code. For example:

    /
  %p This doesn't render...
  %div
    %h1 Because it's commented out!

    is compiled to:

    <!--
  <p>This doesn't render...</p>
  <div>
    <h1>Because it's commented out!</h1>
  </div>
-->

    Conditional Comments: /[]

    You can also use Internet Explorer conditional comments by enclosing the condition in square brackets after the /. For example:

    /[if IE]
  %a{ :href => 'http://www.mozilla.com/en-US/firefox/' }
    %h1 Get Firefox

    is compiled to:

    <!--[if IE]>
  <a href='http://www.mozilla.com/en-US/firefox/'>
    <h1>Get Firefox</h1>
  </a>
<![endif]-->

    Haml Comments: -#

    The hyphen followed immediately by the pound sign signifies a silent comment. Any text following this isn’t rendered in the resulting document at all.

    For example:

    %p foo
-# This is a comment
%p bar

    is compiled to:

    <p>foo</p>
<p>bar</p>

    You can also nest text beneath a silent comment. None of this text will be rendered. For example:

    %p foo
-#
  This won't be displayed
    Nor will this
                   Nor will this.
%p bar

    is compiled to:

    <p>foo</p>
<p>bar</p>
