Go SDK

The Go SDK is now started at packages/sdk-go. This is the first Go/TinyGo shape for Phase 2, not the final component proof.

Current Status

What exists now:

• A Go module at packages/sdk-go.
• Public packages for io, fs, net, time, and locale.
• Example source files for Go clock, cat, and curl-style CLI apps.
• A dependency-free shape check that guards the package layout.

What still needs proof:

• Install Go and TinyGo.
• Generate or wire WIT bindings behind the public helpers.
• Build a real Go component.
• Run that component through krate run.
• Add fixture-backed tests like the Rust samples.

Example

package main

import (
    l36io "github.com/incyashraj/krate/packages/sdk-go/krate/io"
    l36net "github.com/incyashraj/krate/packages/sdk-go/krate/net"
)

func main() {
    args := l36io.Args()
    if len(args) == 0 {
        _ = l36io.Eprintln("usage: krate-go-curl <url>")
        return
    }

    body, err := l36net.GetText(args[0])
    if err != nil {
        _ = l36io.Eprintln(err.Error())
        return
    }

    _ = l36io.Print(body)
}

The longer examples live here:

• packages/sdk-go/examples/krate-clock/main.go
• packages/sdk-go/examples/krate-cat/main.go
• packages/sdk-go/examples/krate-curl/main.go

Tooling

Run:

krate doctor

For this track, these lines should be present:

tinygo          ...
go              ...

If either is missing, the Go runtime proof is blocked. The rest of Krate can continue without them.

Current Check

The normal CI path runs a small package shape check:

node packages/sdk-go/scripts/check-shape.mjs

This does not compile a component. It catches simple mistakes such as missing helper packages, wrong module path, accidental wasi:* imports, or missing public helper names.
