Writing content in amber/ace?

hi can i write content in ace or amber? .md and .org are great for somethings, but sometimes i just want to quickly add classes and not have to type html

i’m thinking of harpjs, which reads .jade, .html and .md out of the box - both for layouts and content.

anything on the horizon?

Not that I know of…in terms of writing content in a templating language, but Hugo already supports Ace and Amber at the template level:

NOTE: If you want to extend your markdown, look into Hugo shortcodes as well.
