Because of those posts I spent my morning reading about arrows which seems a quite interesting concept, although couldn’t yet see what is best for ( I would be curious to learn it in order to try out Yampa). I have to say that the resources I found to learn about arrows on the net were a bit disorganized. This page is really well done http://en.wikibooks.org/wiki/Haskell/Understanding_arrows but then because I don’t know much about parsers I couldn’t really progress through the second half.
I have started an arrow tutorial which many people found easy to follow. It's not finished yet, but since so many people found it useful I'm sharing that unfinished tutorial: http://ertes.de/new/tutorials/arrows.html It answers the most important questions: What? Why? How? To some extent it also answers: When? But I have to work on that question. The basics of the automaton arrow are covered, but when I find time I will extend the tutorial to cover Auto in full. Finally I also intend to cover a powerful generalization of Auto: the wire arrow, which is the basis of the Netwire AFRP library.
