Learning Prolog

2021 Basic syntax (prolog)

Testing basic syntax of Prolog

% Start of script
% The main script for the Kiri voice assistant
% Read from primary libraries
read from "///kiri/LIBraries/voice-commands/1/", nl.
read from "///kiri/LIBraries/ENGINE.pl", nl.
% Main
?- write('Hello, what can I help you with?'), nl.
wait for response, nl.
if no response in 10, nl.
  exit, nl.
  break, nl.
else, nl.
break, nl.
?-
% File info
% File type: Prolog source file (*.pl) Not to be confused with Perl/Raku
% File version: 1 (Monday, 2021 September 27th at 6:03 pm)
% Line count (including blank lines and compiler line): 21

% End of script

This is source code from the main thread of V1 of the Kiri project, which is part of the WacOS Operating system project this script likely does not work at all, it worked very poorly for me, as the syntax kept changing from Perl to Prolog and Prolog to Perl, and I couldn't get the language down due to the confusion. - 2021 Monday, September 27th

Break keyword in Prolog

break;

To this day, I am still not entirely sure what the break keyword does, but most languages support it.

/!\ This example has not been tested yet, and may not work

File extension problem

Prolog and Perl both share the *.pl file extension. This didn't work out too well with me recently, and I have decided upon changing my Prolog files to the *.pro file extension supplied by Prolog. - 2021 September 29th

Possible solution

Prolog seems to support the *.pro file extension as well, I will be using it instead.
