Which wrapper are you using? I just recently did this for the monad
wrapper. It looks a little like this:
data Token
= EOF
|
alexEOF = return EOF
lexAll :: Alex [Token]
lexAll =
do x <- alexMonadScan
case x of
EOF -> []
_ -> lexAll >>= return . (

I'm not the sharpest tool in the shed I'm not really seeing
the obvious way to take the output file of Alex and make a
program that will print out the list of tokens scanned from
an input file.
I had to do something like this this
