Run specific function without running everything

[novitae]

Hey, I was wondering if there was a way to run one function, but not the whole js script. I've only seen examples where only one function is ran. Would there be a way to do the following ?

function hello() {return "hello";};
function world() {return "world";};

>>> evaluated.hello()
"hello"
>>> evalutated.world()
"world"

Hi @novitae - Here's one way to do it using globalThis after evaluating the functions.

import pythonmonkey

pythonmonkey.eval("""
function hello() {return "hello";};
function world() {return "world";};
""")

print(pythonmonkey.globalThis.hello())
print(pythonmonkey.globalThis.world())

which outputs

hello
world

A cleaner approach might be to use separate files and then use CommonJS to require the JavaScript file / module for use in your Python program

myjsfunctions.js

function hello() {return "hello";};
function world() {return "world";};

exports.hello = hello;
exports.world = world;

my_python_file.py

import pythonmonkey
evaluated = pythonmonkey.require('./myjsfunctions');

print(evaluated.hello())
print(evaluated.world())

Output

$ python3 my_python_file.py 
hello
world

Let me know if that answers your question!
