Jake Brownson wrote a game of tic-tac-toe in 160 lines[1] that I thought was beautiful. I forked it to make it a little more readable[2].

I have no idea what you consider clean. I have some ugly code that shows off some Haskell features:

https://github.com/BigDataRepublic/hanon/blob/master/src/Mapper.hs

I think it shows off: - Introducing types to create a language - Explicit IO, allowing for clear contract exposure to the user of the library? - defaultHighlighters is a subset of defaultInputPaths through a simple map allowing for easily exposing constrained subsets of code (not data)??

if I would force myself to continue, the number of question marks would just increase, so I'll stop here.

Best of luck!

I'd like to showoff some nice Haskell code to a CTO with no experience with FP. I promised to send him a small piece of Haskell so he could get an idea. The code should be easy to read, without obscure looking operators (so sorry, no lens, arrows stuff like that), optionally even do something interesting. Who has the nicest example laying around?

Some ideas:

- a wrongly typed piece of code: then show him a) how ghc(i) pinpoints the problem part and is very clear in its demands ("I wanted this, you gave me this") and b) how malleable the type system is.

- a declarative graph made with diagrams (with a graphical result displayed)

- parsec (even if you go with applicative style, the code is very readable) _______________________________________________ Haskell-Cafe mailing list To (un)subscribe, modify options or view archives go to: http://mail.haskell.org/cgi-bin/mailman/listinfo/haskell-cafe Only members subscribed via the mailman list are allowed to post.

Thanks everyone for the awsome examples. I really enjoy the deversity of them. This tops my expectations 8-) 2017-07-01 3:43 GMT+02:00 Will Yager :

I wrote this specifically to be easy to read despite using some cool features (green threads, STM, etc.):

(and yes, I need it by yesterday ;-) )

Thanks!
