Tau Prolog - how to convert a prolog list into a JavaScript array

Asked 2021-Dec-20 at 12:28

I want to use Tau Prolog together with JavaScript on a Node Server, following this tutorial, which works well. I need to convert the answers in a JavaScript compatible format, especially lists to arrays, or objects and vice versa.

I changed the Prolog program and goal in a way that it returns a list

Program: test(t, [64,65,100,120]).

Goal: test(t, X).

which returns with

Just for completeness, I replicate this answer here.

You can write a function to transform Prolog lists to arrays:

QUESTION

Tau-Prolog Interpreter shows different behaviour than SWI-Prolog

Asked 2020-Apr-04 at 19:30

I'm currently trying to implement some basic Prolog queries in Tau-Prolog. Although I have working queries in SWI-Prolog, I can't implement them to work in Tau-Prolog. I would like to return the name of all Robots that are in the database and have the Interface "B". Is there something important I am missing here? I think that sub_string/5 might be the reason why it's not working. It also won't work when I paste the Code into the trial interpreter on http://tau-prolog.org/

Does anyone know a way to fix this query so it could work in Tau-Prolog? Thanks in advance!

Use sub_atom/5 instead of sub_string/5 in the definition of the queryRwB variable as you use atoms, not strings, in the definition of the predicate robot/4:

QUESTION

Tau-Prolog results visible in browser window

Asked 2020-Apr-02 at 11:25

I'm fairly new to Tau-Prolog and Javascript. At the beginning I would like to show some results computed by the Tau-Prolog engine in a Browser.

So far, all I want to show is some information contained in my Prolog-database:

All robots in the database and the interface to connect with a gripper/sensor etc.
All grippers/sensors in the database and the interface to connect to the robot.

The prolog-output would be something like: "Robot A fits with Gripper C (Same interface Z)." I've programmed this in SWI-Prolog and it works fine so far.

Now I would like to show the results in a HTML-Element:

Just an example of handling multiple result, I crafted it creating a page 'tau-prolog.html' in the same folder where had downloaded 'tau-prolog.js', and opened locally in my browser. Then using the developer tools (console, debugger) had a look at inner workings of Tau Prolog.

Beware of details, like

how do you load the Prolog file? in my example I opted for the simpler way, passing the 'program' into a string
how do you start the interaction with the interpreter? in my example I opted for a button, and the most basic handler onclick="..." that loops to extract all answers. Clearly not appropriate for every scenario, but it illustrate the peculiar recursion that Javascript allows. Specially note that the variable session remain in scope among calls.
when you get an answer, only then the callback can decide if looping or quitting...
