Learn Prolog Now

From: "andrew cooke" <andrew@...>

Date: Wed, 22 Oct 2008 20:42:03 -0300 (CLST)

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.

From this article, which went way too fast for me -

This looks like a useful article -

In fact, there seems to be a whole pile of them -

Hi,

What part of the article did you think went too fast or was unclearly
explained ?
Your reply will help me improve it in the time to come.

Thank you

Fast Is Not Necesarily Bad

From: "andrew cooke" <andrew@...>

Date: Mon, 17 Nov 2008 21:58:07 -0300 (CLST)

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
