Hi Luís, personally I don't think HAML or Slim add much when compared to
ERB as Sass (in special) and CoffeeScript add to CSS and JS respectively.
SASS enable developers to add variables to CSS while still being
compatible with plain CSS so it's like a no-brainer as a good default in
my opinion.
CoffeeScript is a mix of new interesting features, less boilerplate and
personal taste. Some don't like it and won't use it, but I personally
prefer CoffeeScript over JavaScript. But you can't deny CoffeeScript
allows you to develop JavaScript classes more easily/ellegantly at least.
For HAML or SLIM, it doesn't provide any actual new feature over
HTML/ERB. It will only provide sugar allowing developers to write HTML
with less code but in the end it boils down to personal developer's
taste. I don't have any strong opinion with regards to HAML or Slim, but
differently from the JavaScript case I don't feel the pain of writing
HTML. My code editor (Vim with plugins) already allows me to write HTML
as quickly as writing Slim templates with a few keybindings and I don't
have any problems reading HTML code. On the other side I don't think I
would have any trouble reading/writing Slim/HAML code either. It's
simply a matter that I don't see any significant advantages of Slim/HAML
over HTML/ERB...
Best,
Rodrigo.

Hi,
I'm not sure if this has ever been discussed, but I couldn't find it
in the issues, so I'll assume it hasn't.
Over time HAML and Slim have been more and more used as html
preprocessors instead of ERB. As we moved CSS and JS preprocessor to
more elegant, indentation based ones, such as Sass and CoffeeScript, I
wonder if it would not be a good move to do that for the HTML
preprocessor as well.
There is much to gain:
* Cleaner syntax
* Less code and boilerplate
* HTML minification by default (in the case of slim)
As to what we might loose is speed, which in the case of slim is not
that much when compared to ERB.
Maybe I'm missing some huge reason why this change has not happened
yet, but either way I believe it is worth discussing.
