v What is the support for wasm?

[JalonSolov]

Compile to C, then use emscripten or similar to create the WASM code.

1. before you start, you need to install libgc

2. read this tutorial compile v to c. remember add -lgc

3. and wasm tutorials is here

from discord vlang wasm

yeah, if you have https://emscripten.org/docs/getting_started/downloads.html installed,

try:
./v -os wasm32_emscripten examples/2048/

it still needs a small fix, since it will generate examples/2048/2048 instead of examples/2048/2048.js, so you would have to rename that

file manually afterwards, but other than that, it should work more or less ok

When can I support the command like rust: Cargo build -- target -- wasm32-wasi xxx.wasm?

For example: v - b -- target -- wasm32-wasi xxx.wasm

[JalonSolov]

v -b wasm xxx.v

Default output is WASI.

You can also be explicit with

v -b wasm -os wasi xxx.v

If you want WASM for the browser, use

v -b wasm -os browser xxx.v

You'll have to come up with your own html file to load it, or copy the one from examples/wasm/mandelbrot/mandelbrot.html

When v is compiled as. wasm, does it use GC or autofree memory management by default?
