I see github applies a syntax coloring to code in view, it seems to be completely static, different rules for different languages but not extensible or customizable.
I wish there was a way to set this up by the repository owner, not a user setting in the browser for reinterpreting github’s rendering.
Same as for whitespace decisions that are built into the code and displayed on github as-is, but it has to be out of band from the code in the case of the syntax coloring.
Use case is rainbow brackets, they help a lot with reading functional code. Looking at my code in my repository, although I tried to make it readable when I was writing it in the IDE where I have a rainbow brackets plugin, it is not as readable on github where it’s presented for others to try to read.
