Exporting predicates in the code loaded into PEngines via the src_text parameter?

The link documents the Prolog API.

Hi Jan. That’s a good point. But be aware, the Javascript API docs use srctext not src_text with an underscore. That still ends up with the Javascript developer passing something that Pengines.js won’t recognize since it is looking for src specifically. My apologies in advance if I am somehow wrong on this. I’ll stick with my change to PEngines.js because I no longer get existence errors when I make calls to predicates in my src_text code since I altered Pengines.js to look for src_text and not src. Now I just have to figure out why call() doesn’t work for me when in the PEngines sandbox:

Problems with "call()" in the PEngines sandbox?

I’m using: SWI-Prolog version 8.0.2 on Ubuntu Linux 18.04. In the code below, you can see a function I created named my_apply/2 to apply a Goal to a list of arguments. This code works fine when I test it outside of PEngines in the SWI-Prolog console. However, when I pass the exact same code in the src_text parameter during the creation of a PEngines instance, I get the following error back: Sandbox restriction! Could not derive which predicate may be called from call(C) '329664db-065f-4c…
