Wasm question

I was given https://hachyderm.io/@unlambda/114582671790895240 as some example code for printing to stdout from inside wasmtime/WASI

It calls a function named "fd_write" taken from "wasi_snapshot_preview1"

"wasi_snapshot_preview1" does not Google well and one link https://github.com/WebAssembly/WASI/blob/main/legacy/preview1/docs.md seems to suggest this is deprecated. How were the functions in wasi_snapshot_preview1 chosen? Is there a wasi_snapshot_preview2 or whatever?

@mcc@mastodon.social @whitequark@mastodon.social @tedmielczarek@mastodon.social I think this is the example you're looking for: https://github.com/bytecodealliance/wasmtime/blob/main/docs/WASI-tutorial.md#web-assembly-text-example
