dy / subscript Goto Github PK

I'm trying (desperatly 😢) to implement an assignment operator. I'd like to be able to update my context with the result of expressions.

This is what I have:

binary('=', 0);
operator('=', (left: any, right: any) => (ctx: any) => {
	// Make sure the left side is a variable reference
	if (typeof left !== 'string') {
		throw new Error('Left side of assignment must be a variable name');
	}

	
	// Evaluate the right side in the context
	right = compile(right);
	const value = right(ctx);
	// Assign the value in the context
	ctx[left] = value;
	// Return the value
	return value;
});

It works for simple expressions like
contextVar = anotherContextVar

But as soon as I use a more complicated expression like
contextVar = anotherContextVar + 2
it fails since my right varible will get an array of values 🤷‍♂️. I feel I'm making a simple mistake here, but I can't seem to figure it out.
Any suggestions?

I have a Nx repository.

The import in TypeScript/Node code works, but the build is broken.

The import in Jest Scripts didn't work at all, no matter what I tried:

   /var/www/example/node_modules/subscript/justin.js:2
    import { skip, cur, idx, err, expr } from './parse.js'
    ^^^^^^

    SyntaxError: Cannot use import statement outside a module

    > 1 | import jstin from 'subscript/justin.js';

My IDE might have found an error:

the third parameter expects a number:

It will be great if this library supports typescript by exposing typescript typings.

Would be nice to have the typical Math functions available, or is this out of scope of this project?

nice work!

I was wondering if there is an approach that would handle async?

let fn = createFn('a + b(3)')
fn({ a: 2,b:x=>Promise.resolve(x)}) // 5

also, it isn't clear why github repo uses createFn and npm uses script in the first example
