For GHC try adding the line
import Data.Char
or
import Char
at the top of your Haskell program. Or in ghci, try Char.chr instead
of chr, etc. Or try
ghci filename.hs
where filename.hs is a text file with the line "import Char" at the
top. Now 'chr' should appear in scope.
The hierarchical li
I'm just starting to learn Haskell from scratch and I've just hit a
snag. The book "Haskell: The Craft of Functional Programming, Second
Edition" uses some examples that call functions from Prelude.hs. But
for some reason, two installations of Haskell that I have on my
computer don't have t

Ok, with all the various opinions, I think I'll:
o Stick with the State monad.
o Switch from |> to $ and teach readers how to read it, "Think of 'f $
g $ x' as 'f of g of x' or 'f(g(x))'. From that point of view, it may
be helpful to read 'f $ g $ x' from right to left."

I use code like:
#ifdef __WIN32__
(Windows code)
#else
(Linux code)
#endif
In Yhc, we use a runtime test to check between Windows and Linux. It
has various advantages - we only have one code base, everything is
type check

Sorry. In the previous email I forgot the subject.
Hi
I’m having a small problem with the portability
of my Haskell code. My code uses wxHaskell and the library for which this one
is the Haskell interface (that is called wxWidgets) doesn’t work in the
same away in Windows and Linux.

Your problem seems to be naturally soved by the State monad, therefore
you should use that.

Unimportant. Ho
