Hi,
I'm not familiar with Parsec, but in ParseLib it's
fairly straightforward, first you add a new combinator:
ifnot :: Parser a -> Parser b -> Parser b
ifnot (P p1) (P p2) =
P

Hi Petra,
Since you are a system administrator, I asume that you will also
want to install FranTk so other people can use it. I'm not sure
this is possible. I did manage to get it working for myself localy,
but a "make install" doesn't do anything.
If you are in a hurry, you can use the fixes be

You can grep for that sentence in "hugs98/src", it will point

If you find it, maybe you could put it in the "Haskell bookshelf" ?
I found very useful and Wiki has been "AWOL" for

Hi,
It seem that any record, no matter how trivial, can't be much
longer than about 200 lines in Haskell. If a try to compile a
300 line record containing just:
data X = X {
f1 :: String,
f2 :: String,
f3 :: String,
...
f300 :: String
}
It needs about 90M h

Mine too.
Actually after writing my own version of "drop" it turns out that
in my case n < 0 is a programmer error and n > length xs a user error.
So what you end
Hi,
This minor inconsistency has been bothering me for some time:
Prelude> drop 10 "test"
""
Prelude> drop (-1) ""
""
Prelude> drop (-1) "a"
"
Program error: Prelude.drop: negative argument
I got these results from Hugs, but the code is identical to that
specified in the Haskell98 standard.
