-- 0) import stylized module
import System.Console.ANSI.Stylized
-- 1) a data type to 'tag' messages:
data MsgType = Info | Warning | Error deriving (Enum)
-- 2) a function from tags to styles:
stylemap :: MsgType -> Style stylemap Info = ((Dull, Green), (NormalIntensity, NoUnderline)) stylemap Warning = ((Dull, Yellow), (NormalIntensity, NoUnderline)) stylemap Error = ((Dull, Red), (NormalIntensity, NoUnderline))
-- 3) a logging function built from 'T' ending functions (i.e. putLnT and putT)
myLogLn msg = putLnT stylemap msg >> resetGR myLog msg = putT stylemap msg >> resetGR
-- 4) some example messages:
msgs1 = [ (Info, "Info Message\n"), (Warning, "Warning Message\n"), (Error, "Error Message") ]
msgs2 = zip (cycle $ enumFrom Info) ["some ", "random ", "messages "]
-- 5) print:
main = do myLog msgs2 myLogLn msgs2 myLogLn msgs1
-- 6) you can always use S-ending functions ('curried' or 'uncurried' ones)
putStrLnS ((Dull, Blue), (NormalIntensity, SingleUnderline)) "blue underlined" putLnS [ (((Vivid, Yellow), (NormalIntensity, NoUnderline)), "vivid yellow ") , (((Vivid, Blue), (NormalIntensity, NoUnderline)), "vivid blue") ]
-- 7) Remember to reset (if you want to)!
