(about http://pleac.sf.net/) pleac is coming along quite nicely, with some active contributers (ocaml, groovy...) as for the haskell entry, Yoann Padioleau wanted to show haskell could be very expressive, so he introduced many new functions/operators. The haskell entry should be renamed because it's really a domain specific embedded language :-) (see http://pleac.sourceforge.net/pleac_haskell/a1102.html) But this does not follow the pleac goal, which aims at showing how to do something the "standard" way. I'm planning to contribute a new haskell entry to pleac, based on Yoann's, but getting rid of the all the wonderful weird stuff, ie plain old haskell :) If someone wanna do it before me (since alas i can't allocate much time on it), please do! -- Pascal Rigaux - http://merd.net/pixel/language-study/syntax-across-languages ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I agree with this. I think many people start with the idea of simple
text processing or something (like summing a list of numbers from a text file,
say) but that stuff isn't really covered because it's so trivial.
But it can be difficult to realise how trivial it is. :)
Hmm, that doesn't make a whole lot of sense, but you see what I'm
getting at. The cookbook approach is great; it's a real shame that the
one Haskell cookbook implementation out there (it was a reworking of a
perl book I think? I can't remember the name) was barely recognisable as
Haskell at all. I think the entire Prelude had been hidden and all the
operators redefined as other things. Maybe it would be useful to start
on that, but using idiomatic Haskell rather than obfuscated Haskell.

*Absolutely* !!!
I'm far from a veteran, but I had intended, when I got some free time,
to knock up a "Cookbook" section on the wiki. I don't see any reason
why a newcomer like me shouldn't do this - in many ways, it's better
to start with some examples from a newcomer's perspective ("these are
the sort of things I found useful") to show the more experienced
people what we're looking for.
So if you have spare time, I'd say you should feel free to do this
yourself. I'd happily contribute. Otherwise, if you wait, I'll get
round to starting it - but be prepared for quite a long wait, as spare
time is in extremely short supply for me just now :-)
Examples needed -- how to connect to a database; to a web service
(e.g. Amazon); read a csv file; represent data equivalent to a
directory listing; a text file/XML; etc...
These all sound good. I was planning on knocking up a "how to get the
results of a query from an Oracle database using Takusen" entry as my
starting point, because that's an example I encountered recently (and
I got a lot of help from the list, so I'd like to give something
back).
All I need now is a spare evening...
