Make Go binaries interface with Dagger

[Xe]

In 3daf7b8, work was started to interoperate Go webassembly binaries with Dagger to get a basic example of reading from the printer facts API online. Unfortunately, a dependency on syscall/js was somehow introduced by compiling the package github.com/Xe/olin/dagger in webassembly mode.

• Discover why github.com/Xe/olin/dagger pulls in syscall/js
  • If JS support is actually needed for now:
    • Integrate Otto and shim together syscall/js
    • Callback support
      • Read documentation on package syscall/js
      • Implement
  • If JS support isn't needed:
    • Hack around it
• Write and test bindings for dagger ABI functions in package github.com/Xe/olin/dagger
  • open
  • read
  • write
  • close
  • sync
• Create http.RoundTripper instance using dagger's http:// and https:// file schemes
• Printerfacts client

Interesting project with some nice approaches to Microservices.

Wondering if Wagon golang project removes the need for Otto ? I have not tried. Wagon with Life yet though but just wanted to check if you have tried Wagon

Update: Seems we can't pull in any of the standard library. I'm gonna fork Go and make my own "OS" that doesn't pull in any of the syscall/js stuff. This is going to result in a lot of very interesting low-level knowledge about the Go runtime.

i think gopherjs might be doing something similar using tags that you can piggy back on. see: gopherjs/gopherjs#833 Its not the same as what you want, which is to run WASM server side. But they are facing the same challenge in a way and take a similar route. The other thing might be to liase with the golang team first too, so that what you do an be pushed upstream into golang proper later too.

Putting this on hold for now. Rust works.

Maybe time to check out the WASI support for this?
