I can have
%a{href: '#', data_toggle_description_length: 'toggle_me_ajax'}
which it gives me underscores not dashes, i.e.
<a href="#" data_toggle_description_length="toggle_me_ajax"></a>
However I want to have HTML5 data-
attributes, i.e.
<a href="#" data-toggle-description-length="toggle_me_ajax"></a>
but when I try replacing underscores with dashes, i.e.
%a{href: '#', data-toggle-description-length: 'toggle_me_ajax'}
I get syntax errors:

Try this:
%a{"data-toggle-description-length" => "toggle_me_ajax", href: "#"}
OR
%a{href: "#", :data => {:toggle_description_length => "toggle_me_ajax"}}
For more details refer here
You can also use html2haml converter available online
EDIT:
As mentioned in comments there are a couple more syntaxes which would work
%a{href: "#", { "data-toggle-description-length": "toggle_me_ajax" }}
OR
%a{href: "#", { :"data-toggle-description-length" => "toggle_me_ajax" }}
I would still prefer first two though as I think latter ones look ugly and kinda messy.
