Haskell, possible indentation error that I can't get rid of -


i have problem , cannot find out is. have reindented again on , over, cannot find solution. there else can dependent on?

code:

type triple = (prime, quot, gen)  correctness :: triple -> bool correctness (p,q,g) = prime && plength && qlength && divisor && orderq            prime   = probablyprime n 5                  qlength = q < 2^1024                  plength = p < 2^160                  divisor = (p-1 `mod` q) == 0                  orderq  = (g^q mod p == 1) && (g > 1)

error message (line 94 corresponds "correctness :: triple -> bool"):

crypt.hs:94:0: parse error (possibly incorrect indentation)

edit: solved problem. problem syntax error in above function. had otherwise m_ify m*2 instead of otherwise = m_ify m*2

you might need add backticks around mod in final line. wouldn't cause indentation error report, following compiles me:

n = undefined probablyprime = undefined type prime = int type quot = int type gen = int  type triple = (prime, quot, gen)  correctness :: triple -> bool correctness (p,q,g) = prime && plength && qlength && divisor && orderq            prime   = probablyprime n 5                  qlength = q < 2^1024                  plength = p < 2^160                  divisor = (p-1 `mod` q) == 0                  orderq  = (g^q `mod` p == 1) && (g > 1)

the change here (apart first 5 lines) in last line.
