    From Newsgroup: comp.lang.prolog

    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:

    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.

    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
    <tri...@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 <eta...@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.Ka...@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.)

    Many commercial systems are listed in the Prolog Resource Guide. The Resource Guide also lists many systems which are not exactly
    "commercial", but available for a price from research institutions. The
    list of such systems was originally compiled by Chris Moss, of Imperial College. The rest of the Resource Guide was originally compiled by Dag Wahlberg, of Uppsala University.

    The Prolog Resource Guide hasn't been updated lately, but nevertheless
    still contains some valuable information. It can be found at http://www-2.cs.cmu.edu/Groups/AI/html/faqs/lang/prolog/prg/top.html.

    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.

    Here are some of the most popular books on Prolog.

    and related material by the convenor of WG17.

    For questions about the standard, use this newsgroup or Stackoverflow.

    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.

    12. Is there a WWW page on logic programming?

    Yes, there is one by Jonathan Bowen; the URL is http://www.afm.sbu.ac.uk/logic-prog/. He invites us to mail him at <jonatha...@sbu.ac.uk> with any relevant information for inclusion.

    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
    l

    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:
    http://www.amzi.com/AdventureInProlog/advfrtop.htm
    + On-line guide to Prolog Programming: http://kti.ms.mff.cuni.cz/~bartak/prolog/index.html
    + Prolog Programming, A First Course: http://computing.unn.ac.uk/staff/cgpb4/prologbook/book.html
    + Learn Prolog Now!: http://www.learnprolognow.org

    Intermediate to advanced level:

    + https://skolemmachines.org/ThePrologTutorial/

    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).

    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
    <tri...@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 <eta...@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.Ka...@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.)

    list of such systems was originally compiled by Chris Moss, of Imperial College. The rest of the Resource Guide was originally compiled by Dag Wahlberg, of Uppsala University.

    The Prolog Resource Guide hasn't been updated lately, but nevertheless
    still contains some valuable information. It can be found at http://www-2.cs.cmu.edu/Groups/AI/html/faqs/lang/prolog/prg/top.html.

    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.

    Here are some of the most popular books on Prolog.

    9. Are there any WWW archives of comp.lang.prolog ?

    Yes, there are: Google Groups has archives of news://comp.lang.prolog/.
    They can be found at https://groups.google.com/forum/#!forum/comp.lang.prolog

    10. How can I get the ISO Prolog standard? Where can I go for more information about it?

    You can obtain the approved international standards from your national member body or directly from ISO (http://www.iso.org).

    The working group on Prolog standardisation is ISO/IEC JTC1/SC22/WG17 (http://www.sju.edu/~jhodgson/wg17/).

    Contacts:

    + Convenor of WG17: Ulrich Neumerkel
    (<ulr...@mips.complang.tuwien.ac.at>)

    Further literature: "Prolog: The Standard (Reference manual)", P.
    Deransart, A. Ed-Dbali, L. Cervoni, Springer Verlag (1996). Extra information can be found on http://pauillac.inria.fr/~deransar/prolog/docs.html

    http://www-2.cs.cmu.edu/afs/cs.cmu.edu/project/ai-repository/ai/lang/pr olog/doc/standard/ contains the December 1991 draft, the March 1993
    draft, Michael Covington's summary of it, and Richard O'Keefe's 1984
    Prolog standard draft.

    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.

    12. Is there a WWW page on logic programming?

    Yes, there is one by Jonathan Bowen; the URL is http://www.afm.sbu.ac.uk/logic-prog/. He invites us to mail him at <jonatha...@sbu.ac.uk> with any relevant information for inclusion.

    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
    l

    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:
    http://www.amzi.com/AdventureInProlog/advfrtop.htm
    + On-line guide to Prolog Programming: http://kti.ms.mff.cuni.cz/~bartak/prolog/index.html

    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).
