A simple, primitive question:
has anybody here used in a non-trivial way the showsPrec anti-parser?
My students asked me what is it for, it is never used in the Hugs
Prelude, OK, once: possible parentheses around fractions n%d.
I explained that it is a good contraption to make one own pretty-
has anybody here used in a non-trivial way the showsPrec anti-parser?
Isn't the idea to make things trivial while avoiding performance
penalties? Perhaps: simple pretty-printing of abstract syntax trees?
I often use it to get simple debugging output for complex internal
data structures (first,
Hi,
I've just recently learned about Haskell, and I'm
impressed by the abstractions and expressiveness that
it affords. I'm particularly interested in it for a
small parser project that I'm planning.
However, my main programming languages are Python and
C++, and for various reasons switching
I hope we don't have a repeat of the MathWorld website
shutdown.* I also can't find a webpage with the definition
of Standard ML... only avaible in print from MIT Press?

If you are steaming with compicated codes, then how about taking a break.
Let's play with a simple cat.
\begin{code}
main = mapM (=putChar) getCharS where getCharS = getChar:getCharS
\end{code}
Tested with ghc.
Works good except that you get some messages on stderror
because eof is not
