haskell - parsing n hex digits using attoparsec -

okay need parse n digits of hex , having problem cant stop standard attoparsec hex parser hexadecimal . my first idea this: nhex n = take n *> hexadecimal doesnt work because takes off 4 digits parses rest of string xd next idea works this: hex :: (num a, eq a) => int -> parser hex n = fst . head . readhex <$> count n (satisfy ishexdigit) but problem code in attoparsec library warns against returning lists of chars speed concerns , hex parser base of whole program next idea try better speed this: parsefragments :: (bits a, integral a) => int -> parser parsefragments n = fourchars <- b.take n let hexdigits = parseonly hexadecimal fourchars case hexdigits of left err -> fail err right x -> return x but feels terrible hack using parseonly. there fast way more idiomatic? data.attoparsec.bytestring.char8.hexadecimal implemented as : hexadecimal :: (integral a, bits a) => parser...

i need remove body of constructors , methods w/ void return type using javassist library. following works. ctclass.getconstructors()[0].setbody("int = 0"); but doesn't ctclass.getconstructors()[0].setbody(""); instead exception compile error: syntax near "" when try ctclass.getconstructors()[0].setbody(null); i get compiler error: no such constructor i same error when trying empty method w/ void return type. looking through google , documentation, can't figure out how empty out body without inserting kind of code , don't want add arbitrary code no reason. javassist replaces method body valid block body of method. non-statement not valid block. can instead set { } method body block. alternatively, make implicit return; statement explicit. for constructor, required invoke super costructor or auxiliary constructor first. empty block not valid.
