Fwd: how to enrich a linguistic app using CIAO with with sound and picture
by oui＠mailoo.org 04 Aug '14

Hi Jose Your answer is in my view very important and very good for all user being operating with texts! Thank you very much! Probably it is also included in the manual but it is very difficult to find the item of manual... For people willing to treat linguistic problems and making them attractive for other people, two or three things can help a lot: - show a jpeg picture of the object of the word or fact being related by the sentence - send a wave file (or mp3), to show or check how to pronounce. How to send both to the standard output and - clear the screen (as far as probably needed) before to continue the dialogue? Kind regards

how to / exemple for using CIAO with unicode contents

Hi I am searching for exemples for using CIAO Prolog with unicode contents. Are they possible in atoms and variables or only in variables? How to elaborate unicode contents for HTML? Is there somewhere a bibliothek online for Proloog applications using both? Kind regards

Substitues for get0 and get predicates?
by GreyHat LispHacker 14 Jul '14

14 Jul '14

Hello, Apologies for this rather elementary question. I'm learning prolog via Michael Covington's Prolog Programming in Depth and working through the examples using Ciao 1.14.2. (The book, and source files can be found at: http://www.covingtoninnovations.com/books.html). I'm having difficulty getting the car.pl example to work (pg 54-60). He uses the following to parse a single character input (Y or N): get_yes_or_no(Result) :- get(Char), % read a character. get0(_), % consume the Return after it. interpret(Char,Result), !. % cut -- see text Apparently, Ciao has neither a a get/1 nor a get0/1 predicate. As far as I can tell, the original get0/1 predicate parses a return character, unifies it with an anonymous variable (resulting in yes), and then procedes to the predicate interpret(). I changed get(Char) to get_char(Char), and get0 to get_code(_), but this puts me in an endless loop that calls get_yes_or_no again. get_char(_) is similarly incorrect. Is there a predicate that is exactly equivalent to get0(_), or is there a more complex solution involving streams? Thanks in advance.

Yes, use the more modern (ISO) get_char/1 and get_code/1. With: get_yes_or_no(Result) :- get_code(Char), % read a character get_code(_), % consume the Return after it interpret(Char,Result), !. % cut -- see text you should get: > ?- get_yes_or_no(Result). > |: Y > > Result = yes ? > > yes > ?- get_yes_or_no(Result). > |: N > > Result = no ? > > yes > ?- get_yes_or_no(Result). > |: l > > Type Y or N:l > > Type Y or N:l > > Type Y or N:l > > Type Y or N:Y > > Result = yes ? > > yes > ?- You can get a loop if you use get_char/1 instead of get_code/1 since interpret/2 (which expects an ascii code) will fail before the cut and execution will go to the second clause.
