Two years ago I was writing a computing book for Oxford University Press and we realised that there was literally no way to properly style code in a document. We quickly noticed that many others were taking images to show code and we were not happy about it and so we came up with a complicated work around. How I wish this had already been made! It is fantastic and automatically formats code with understanding of the syntax. A great tool, great for everyone for printing and it even includes Swift, which many syntax highlighters don't have. This is great for anybody who needs to teach or document code.
