Less: Show line numbers origin file and line numbers in rendered CSS

css, less

Solution

There is now an option in dotless to output this information as per sass does. the flag is "debug". It will be included in the next release - https://github.com/dotless/dotless/issues/186

Problem

Is there any way in LESS to render the original LESS File + Line Number in the rendered CSS? Just as Middleman does with SASS... (I'm not sure if it is a SASS or a Middleman feature)
