Add WebAssembly as Compiling Target

[wangyenshu]

It would be quite interesting to see if it is possible to compile Macaulay2 to WebAssembly. This will allow Macaulay2 to be used in browser as a static website and also to be integrated into JavaScript ecosystem.

As a reference, I had some experiments in porting Singular CAS to WebAssembly:
demo:
https://wangyenshu.github.io/Singular-wasm/
build script:

Interesting yes, and an interesting project, but likely of limited use unless you also bundle gfan and normaliz and a bunch of other software that M2 relies on as well.

You are right. That is possible and requires more work. To see what the WebAssembly version of Macaulay2 could achieve, you can try this demo:
https://wangyenshu.github.io/Macaulay2-in-Browser/
It runs a complete Macaulay2 as a static website by a WebAssembly based x86 emulator. If M2 could be compiled to WebAssembly, the performance, including startup time, memory usage and web downloading size will be much better.
