I compiled graphite to a wasm library and and integrated it with hb-wasm-api, then embedded it in CharilSIL. The CharisSIL font is 1.7MB. The Wasm table with entire graphite library in it is 110kb. It renders.

I think with a bit of polish this can actually be merged as an experimental feature, off by default.

Maybe better to add API docs to hb-wasm-api.h and point people to that instead?

The API masquerades the font/face/buffer tokens as pointers, for more natural-looking representation. Any reason you explicitly talk about tokens?
You don't do that about blobs.

I guess it's because they're opaque pointers which refer to memory in Harfbuzz-land, and you can't do anything with them, whereas you can dereference and use the blob data. I've no objection to calling them pointers if you prefer.

I wrote this because I received complaints that "read the header file" was not adequate documentation. :-)

I think I prefer that since that's what's in the API. Up to you though.

I meant documenting the API and having gtkdoc generate API docs like our normal API documentation.

Thanks for this.

Hi,
I see that this has been release but I could not find any example/documentation/mention of it anywhere (beside in the code of harfbuzz itself).
Is there any open source source implementation of wasm font example somewhere in the wild? As for example the demo fonts that were shown at ATIPY? That would be very helpfull as a starting point to experiment with wasm. Thanks!
