Prolog Programming in Ubuntu
I have an interest in playing and fuxing with prolog, I have installed the swi-prolog and added the repository, just in case anyone is interested on which one commands I used:
% sudo apt-add-repository ppa:swi-prolog/stable
% sudo apt-get update
% sudo apt-get install swi-prolog
How do I actually begin to write prolog codes on my linux machine? for my regular programming I use VIM to write/edit/debug and terminal to compile. Can I use vim to write prolog? How do i compile or use the prolog interpreter(i think that is what it is called)?
Answer
Yes, you can use any text editor, incl. VIM. Once you have written a Prolog source file, say, file.pl, you can load it into SWI-Prolog like so:
swipl -s file.pl
This will compile your file and take you to an interactive shell where you can then ask queries against the definitions in your file.
If you want to use your Prolog program in batch mode, you can use:
swipl -s file.pl -t goal
where goal is the goal/query you want to evaluate. Note that in this case you won't be getting the option to ask for alternative solutions.
