I am developing a package that changes the appearance of source code given some dynamic criteria. One of these changes is to make line appear as inactive - effectively changing the color to the one of a comment.
I managed to create a marker and add class to given line. However, I couldn’t find a way to set color as comment (preferably as variable). In https://github.com/atom/atom/blob/master/static/variables/syntax-variables.less I see list of variables for various language entities, but comment is missing.
