Free book - http://www.coli.uni-saarland.de/%7Ekris/learn-prolog-now/html/prolog-notes.pdf Chapter 7 looks interesting - an explanation of definite clause grammars. I know the basic ideas behind Prolog (ie unification, Horn clauses), but not the parsing stuff.

This looks like a useful article - http://gnosis.cx/publish/programming/charming_python_b11.txt In fact, there seems to be a whole pile of them - http://gnosis.cx/publish/tech_index_cp.html Andrew

Fast Is Not Necesarily Bad

Hi - sorry for not replying earlier (I filter email submissions to my site
because of spam, and only get maybe 2 or 3 genuine comments a year, so
forget to check the filter...).
I think the problem was mainly that, although I know the basics behind
Prolog, I have never read through a "real" Prolog program. So it wasn't
difference lists, or the DCG stuff, but all the noisy details about how
you structure something more complex than the very simple examples I read
before.
But I do not think this is a bad thing! The web is full of very very
simple examples that show how to append a value to a list, or generate
permutations. You should not try to reproduce that. I learnt more from
your page when I read it (and more again now, skimming it through to
remind myself what it was all about) than I ever have done from simpler,
"too easy" pages.
I'm sorry my criticism ("way too fast") was inaccurate and unhelpful, and
I think your page is excellent as it is. It would have been better for me
to say something like "too much detail for me to understand everything in
a few minutes of scanning"... (because of how this site is generated it's
not trivial for me to modify anything already posted, or I would do so).
Cheers,
Andrew
