Well, I'm currently working on a Text version of wl-pprint, which will probably suit your needs better than Bytestring. As for coloured text, there's ansi-wl-pprint, but it's more for terminals (how exactly do you want to output your results?). -- Ivan Lazar Miljenovic [email protected] IvanMiljenovic.wordpress.com _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
