Thanks for your PR. Is it for https://atom.io/packages/language-slim or maybe https://atom.io/packages/slim-language?

I'm still unsure how many/which languages should be included.. see simurai/duotone-syntax#2. But as said in the comment, we can think about it later again.

This is for slim-language. I found one issue in each package:

The slim-language don't highlight attrs (the printscreen is after my modification) and don't highlight inline ruby:

and language-slim don't highlight attrs:

My PR cover the attrs for slim-language package

Is it possible to fix it in both language packages without messing each other up?

Or maybe it's better to fix it in the actual language package itself and not each theme.

To remove the slim.less file we can replace .html.attribute-name with just .attribute-name.

I don't know exactly how language package works, but the problem is the parser isn't adding the right classes.
Maybe this line could be the point to solve the language-slim problem with attributes.

That might be a good idea. Actually, in _base.less, there shouldn't be any language specific selectors anyways.

Ya, currently "language-slim" adds entity name tag slim to attributes. A more specific attribute-name would help. Feel free to open an issue there.
