Go

A cgo wrapper over the C ABI. Construct a Shazam from a JSON spec, then drive it with Command(json) -> json — index first, then match.

bash

go get github.com/wickra-lib/wickra-shazam-go

package main

import (
	"fmt"

	wickra "github.com/wickra-lib/wickra-shazam-go"
)

func main() {
	spec := `{"features":[{"kind":"price","field":"close"}],
	  "window":10,"metric":"euclid"}`

	shazam, err := wickra.New(spec)
	if err != nil {
		panic(err)
	}
	defer shazam.Close()

	if _, err := shazam.Command(`{"cmd":"index","history":[]}`); err != nil {
		panic(err)
	}
	report, err := shazam.Command(`{"cmd":"match","current":[],"k":5}`)
	if err != nil {
		panic(err)
	}
	fmt.Println("wickra-shazam", wickra.Version())
	fmt.Println(report)
}
