Go encoding module for ETF (External Term Format).

The external term format is mainly used in Erlang's distribution system. Occasionally, it's necessary to encode and decode this particular binary format for communication between different APIs. This format offers the advantage of being faster and more lightweight compared to traditional JSON.

• go v1.22+

go get -u github.com/nicolito128/goetf

package main

import (
	"fmt"

	"github.com/nicolito128/goetf"
)

func main() {
	phrase := "Hello, world!"

	data, err := goetf.Marshal(phrase)
	if err != nil {
		panic(err)
	}

	fmt.Println("Encoded:", data)
}

package main

import (
	"fmt"

	"github.com/nicolito128/goetf"
)

func main() {
	var out int

    bin := []byte{131, 98, 0, 0, 1, 1}
	if err := goetf.Unmarshal(bin, &out); err != nil {
		panic(err)
	}

	fmt.Println("Out:", out)
}

For both examples, use the go run command, like:

go run example_file.go
