Calling an already loaded function in Skulpt

sandeep-gh opened this issue 3 years ago · comments

I have gone through documentations as best I could but couldn't figure how to achieve a few simple things-- essentially, I want to load a function in the Sk runtime and later invoke the function maybe with some arguments.
To illustrate, below is the code snippet (full code attached at last):

    prog = `def square(x):
    return x*x
`
    
    var module = Sk.importMainWithBody("<stdin>", false, prog);

What I want to do, is call the square function. Either via Python or via javascript:
I tried as follows:

for python

prog=`square(5)`
Sk.importMainWithBody("<stdin>", false, prog);

for javascript

var pyf_square = module.tp$getattr('square');
var ret = Sk.misceval.callsim(runMet, 10);

Neither of them work.

It seems this should be fairly straightforward for Skulpt to do. I am missing something trivial but can't find it.

    }

    function outf(text) { 
    var outhe = document.getElementById("output"); 
    outhe.innerHTML = outhe.innerHTML + text; 
    }
    var pre = document.getElementById("output");
    pre.innerHTML = '';
    Sk.pre = "output";
    Sk.configure({output:outf, read:builtinRead});
