This is the an example rendering of a piece of code. It contains most of the syntax in Elixir. 
Atoms are purple, and have on issue: if they are followed by more text, that is syntax highlighted as well as an atom.  
Therefore I made the comma a keyword as well, and used a space as a delimiter for an atom. So if you use a space afterwards, there problem is gone.
