Hey @ziyaointl, should we implement preload for p5py. Preload docs link

Called directly before setup(), the preload() function is used to handle asynchronous loading of external files in a blocking way. If a preload function is defined, setup() will wait until any load calls within have finished

It seems preload waits for the asynchronous functions to finish and then proceeds with setup and draw.

We can just load stuff before the setup in our python sketches so it seems there is no specific need for a preload function IMO.

// load fonts, images etc here

def setup()...

def draw().... 

Handling async loading calls might go a bit off for the project's scope. The priority seems low as well so we can keep it for future releases.

Thoughts?

I think it's ok to implement preload for completeness - it's easy to implement (I don't think we need to do anything extra for async calls) and does not incur much of a performance cost, but I agree that it could be deferred to future releases.

I have made implementing preload a good first issue for folks in the community. It would not affect loadFont and other APIs so someone else could contribute to it parallely.

[tushar5526]

Turns out preload is needed because load_font will depend upon the current renderer and we have to wait till run() is called and p5.renderer is assigned. So, I have implemented it.

Closing this issue.
