Hello Haskellers,
I want to make a QuickCheck generator that creates identifiers, basically [a-zA-Z] as the first character and then [a-zA-Z0-9-_] for a total of 63 characters. So, I've got up to:
do s <- choose (1, 63 :: Int) elements validFirstChars where validFirstChars = ['a'..'z'] ++ ['A'..'Z'] validChars = validFirstChars ++ "_-" ++ ['0'..'9']
which of course only gives me one random character. I want both, the characters, and the length to be random.
do n <- choose (1, 63) replicateM $ elements validFirstChars Jonathan Cast http://sourceforge.net/projects/fid-core http://sourceforge.net/projects/fid-emacs
