Hello lists, I'm pleased to announce the first release of data-textual[1], a library that provides human-friendly counterparts (called Printable/Textual) of the compiler-friendly Show/Read type classes. The library is intended to be used for printing and parsing of non-compound and non-polymorphic compound data (e.g. numbers, network and hardware addresses, date/time, etc). A quick example (vs network-ip[2] library): λ> import Data.Maybe (fromJust) λ> import Data.Textual λ> import Network.IP.Addr λ> let x = fromString "[dead::b:e:e:f]:123" :: Maybe Inet6Addr λ> x Just (InetAddr {inetHost = ip6FromWords 0xdead 0x0 0x0 0x0 0xb 0xe 0xe 0xf, inetPort = 123}) λ> toString (fromJust x) "[dead::b:e:e:f]:123" λ> let y = fromStringAs aNet4Addr "192.168.100.1/24" λ> y Just (netAddr (ip4FromOctets 192 168 100 1) 24) λ> toText (netPrefix $ fromJust y) "192.168.100.0" [1] http://hackage.haskell.org/package/data-textual [2] http://hackage.haskell.org/package/network-ip
