Web version

I think It would be great to use this tool on the web with webassembly.

This implementation depends on being able to access source code and the binary. While uploading the binary is a trivial change, however accessing the local disk -- not so much. It'll be probably easier to run the program locally and use it that way.

I'm not against someone adding it, but I don't see a reason to add it myself.

Sure, WebAssembly support definitely would be nice.

However, for supporting wasm you need a way to get source-line mapping... and AFAIK, Go doesn't emit dwarf/line-info golang/go#33503

TinyGo might have sourcemap support, but I haven't checked.

So the first step would be to add necessary support for them.

Hackpadfs seems rather large dependency and I wouldn't want to pull it in. It also doesn't seem to solve the problem of accessing the data.

Yes, it works with TinyGo (just checked)

@gedw99 the issue of getting data to the program isn't about having a filesystem, it's about uploading and/or binding to the local filesystem.

@llindemann Got a demo of this ?

@gedw99 Yes, here: https://blog.noops.land/debugging-webAssembly-from-go-sources-in-chrome-devtools
