Hi Ivan, Yes, I want it printed in a terminal window.
I want to be able to run it from the command line in a terminal window, and have the text come up in colours (but very fast). My current version is already very fast, but I've heard everyone raving about how slow Strings were to use for I/O, so I wanted to _experiment_ with ByteStrings to see the performance difference. I'm experimenting with writing a Zork-like text adventure game and I just wanted to do some space/time profiling on different pieces of code and observe the results. I thought that ByteStrings might be the way to go, but can they be combined with the Doc type from the ansi-wl-pprint library?
