Reusing compiled/evaluated code

[danielsvane]

I'm trying to generate an isosurface, and right now I'm running the same expression, with replaced variables 15000+ times. Is there any way to optimize this call:

Algebrite.eval(eq, "a", a, "b", b)

Thanks for all your work.

Hi, yes in the Zeno branch there are some JS code generation facilities. I'll have to refine and document them, but if you look for "generation" you'll find the trail.

[danielsvane]

My best bet is findDependenciesInScript(), which kinda generates JS code, but doesn't replace "cos", "sin" and "e^x" gets replaced with "Math.pow(exp(1), x)". For now I made a parser in nearley to get JS code I can eval, but it's not a very elegant solution.

my vote goes for using/improving that code generation facility. It's a draft, true, but I'm going to keep working on it, so I'd find any improvements on that very useful, they will be included and maintained...

After updating to 1.0, the code generation works well for my use case. Algebrite.findDependenciesInScript("expression")[1] successfully returns a JS expression that can be evaluated. The name of the function is not the greatest, but I'm not gonna complain. Thanks for maintaining and updating this library, it has helped me a great deal.
