General Information: This article contains the answers to some
Frequently Asked Questions (FAQ) often seen in
news://comp.lang.prolog/. It is posted (twice a month, currently on
the 2nd and 16th) to help reduce volume in this newsgroup and to
provide hard-to-find information of general interest.

The World Wide Web URL for this FAQ is:
http://www.logic.at/prolog/faq/

Please send questions about the FAQ and updates to
<triska@logic.at>.

1. What is the Association for Logic Programming?

To keep up with the current state of logic programming technology,
readers can join the Association for Logic Programming (ALP) and
receive their Newsletter. For details on how to join or send in
contributions, check http://www.cs.nmsu.edu/ALP/ or contact

Sandro Etalle <etalle@cs.utwente.nl>

The Prolog Resource Guide (v0.6) was printed in issue 5/1 of the
Newsletter (Feb. 1992). This lists information concerning Prolog
Archives, Books, Suppliers, etc. It is now maintained by Mark
Kantrowitz (<Mark.Kantrowitz@glinda.oz.cs.cmu.edu>), and used to be
posted periodically to news://comp.lang.prolog.

2. Where can I get a free Prolog for system X (PC, Mac, Unix or other)?

The following are anonymous-FTP sites for free Prologs (or related
languages) which are either in the public domain or are "copy-lefted"
(permitted to be copied with some restrictions on commercial use).

(Please note that for extensive development work, users will probably
want a robust interpreter or compiler with good debugging facilities
and a standard syntax, among other things. While public-domain systems
are a valuable service to the community, they do not necessarily have
all these things, and users should weigh carefully what they want to do
against the capabilities and costs of the available systems.)

Once a while doing some dust cleaning. Found links
that disappeared, not showing anymore what they
were showing in the past:

https://github.com/Peter-Gabel/ArityProlog32 is gone, 404 error

http://www.probp.com/ is gone

https://www.lpa.co.uk/ind_dow.htm is gone, 404 error

http://www.cs.tcd.ie/open-prolog/ is gone

http://www.cs.bham.ac.uk/research/poplog/freepoplog.html is gone

https://www.sju.edu/~jhodgson/wg17/ is gone

http://wambook.sourceforge.net is gone

https://www.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/prolog/0.htm is gone, 404 error

https://lernen.bildung.hessen.de/informatik/swiprolog/indexe.htm is gone

Sites with other errors, according to Chrome browser.
Mostlikely the Chrome browser wants https, thats why
these connections bail out with a warning page:

http://www.ifcomputer.de/Products/Prolog/ time out

http://ctp.di.fct.unl.pt/~amd/cxprolog/ not secure

http://www.itee.uq.edu.au/~pjr/HomePages/QuPrologHome.html not secure

http://www.learnprolognow.org/ not secure

http://eclipse.ime.usp.br/projetos/grad/plugin-prolog/index.html not secure

The security warning could be also caused by missing automatic
http to https promotion. Did not test whether another protocol like
https would work, used the links verbatim as found in this FAQ.

> 5. I think language X is better than Prolog. What do you think?
>
> These debates rarely result in any productive discussion. To some
> extent, one's favourite language is based on irrational ideology.
>
> However, many people now agree that different languages are good for
> different things. Prolog seems to be good for problems in which logic
> is intimately involved, or whose solutions have a succinct logical
> characterization. Like other interactive, symbolic languages, Prolog is
> also good for rapid prototyping.
>
> Also, note that there are many different "Prologs" and other logic
> programming languages available, all with different capabilities.
>
> 6. What are the recent developments?
>
> There are some languages in development which do not have Prolog
> syntax, but do subsume and generalize Prolog's logic programming
> abilities.

> 7. My Prolog prof assigned me this problem. Can you help me with it?
>
> If your instructor assigned it to you, he or she probably wanted you to
> do it yourself. If it's an introductory Prolog course, your question
> might be elementary to most readers, so it might be a waste of network
> resources to ask it. Please ask your instructor, a friend, a teaching
> assistant, or a local newsgroup for help first.
>
> That being said, there are news://comp.lang.prolog/ readers who would
> be glad to help people making a legitimate attempt to learn Prolog.
>
> 8. Can you suggest some books on Prolog?
>
> The Prolog Resource Guide (see above) contains a listing of Prolog
> books. It is maintained by Mark Kantrowitz
> (<Mark.Ka...@glinda.oz.cs.cmu.edu>), and posted periodically on
> news://comp.lang.prolog.
>

> 11. How does the WAM (Warren Abstract Machine) work? How do I write a
> WAM-based compiler or a WAM emulator?
>
> Reportedly the best tutorial is Hassan Ait-Kaci's book "Warren's
> Abstract Machine: A Tutorial Reconstruction" (MIT Press, 1991). The
> book is out of print, and available online at
> http://wambook.sourceforge.net.

>
> A collection of artifacts from logic programming languages beginning
> with Marseille Prolog is available from
> http://www.softwarepreservation.org/projects/prolog/index.html
>
> A large amount of Prolog code is available from the CMU AI Repository:
> http://www.cs.cmu.edu/afs/cs/project/ai-repository/ai/lang/prolog/0.htm

> Recently, Stackoverflow has become a valuable resource for Prolog
> questions and answers: http://stackoverflow.com/questions/tagged/prolog
>
> Another community resource is the #prolog IRC channel on
> irc.libera.chat.
>
> 13. Can I do Internet/WWW programming with Prolog?
>
> Prolog is very suitable for this task. Several commercial and free
> implementations include special support for it. A page specifically on
> this topic (including some tutorials) is maintained at
> http://www.clip.dia.fi.upm.es/lpnet/lpnet.html. A public-domain library
> exists (PiLLoW) for several popular Prolog systems which helps in the
> task. See: http://www.clip.dia.fi.upm.es/Software/pillow/

> 14. Is there a WWW page with some tutorials on Prolog?
>
> Beginner level:
>
> + Adventure in Prolog:

> 15. How do I edit Prolog code?
>
> Emacs and VIM ship with basic support for Prolog. A much improved Emacs
> mode is maintained by Stefan Bruda and available from
> https://bruda.ca/emacs/prolog_mode_for_emacs
>
> Logtalk ships with various editing services for many common editors,
> also usable for Prolog.
>
> SWI Prolog has a built-in Emacs clone called PceEmacs. There are also
> Emacs definitions that let you evaluate embedded queries:
> https://www.metalevel.at/ediprolog/. An SWI Prolog programming
> environment suitable for schools is available from
> http://lernen.bildung.hessen.de/informatik/swiprolog/indexe.htm

> A Prolog plug-in for the "Eclipse"-IDE is available from:
> http://eclipse.ime.usp.br/projetos/grad/plugin-prolog/index.html
>
> A sophisticated integrated editing and teaching environment with
> declarative debugging, termination analysis and many visualisations is
> available from http://www.complang.tuwien.ac.at/ulrich/gupu/
>
> 16. How do I publish Prolog code?
>
> Logtalk ships with support for various syntax highlighters, also usable
> for Prolog. These include support for Pygments (used e.g. on Trac and
> GitHub), Rouge (use e.g. in GitLab), GeSHi (used e.g. on Wikis), minted
> and texments LaTeX packages (e.g. source code listings), Google Code
> Prettify, Source-highlight, Highlight, SyntaxHighlighter, and SHJS
> (JavaScript highlighter for e.g. web pages).
