[Haskell-cafe] Is there already a lib to parse a line of string with a pattern and generate key-value map or a record?

[Станислав Черничкин]

I think specific formats can be parsed with attoparsec
(Data.Attoparsec.Text):

p = do
   year <- yearP
   char '/'
   month <- monthP
   char '/'
   ....
   return (year, month, ...)

You may also use cassava to parse csv-like files, or Frames for type-safe
parsing. With Frames you may custom readers (
http://acowley.github.io/Frames/#orgfa57664 ) with complex
pattern-matching, this will require typing skills though.
