A Go library for Varlink.
Given a Varlink definition file:
interface org.example.ftl
method Jump(latitude: float, longitude: float) -> ()
Client and server code can be generated:
go run github.com/emersion/go-varlink/cmd/varlinkgen -i org.example.ftl.varlink
This can be performed with go generate:
//go:build generate
package ftl
import (
_ "github.com/emersion/go-varlink/cmd/varlinkgen"
)
//go:generate go run github.com/emersion/go-varlink/cmd/varlinkgen -i org.example.ftl.varlinkThe generated file contains a Client, with one Go method per Varlink service
method:
client := Client{varlink.NewClient(conn)}
_, err := client.Jump(&JumpIn{37.56, 126.99})It also contains a Handler implementing the Varlink service, and a Backend
interface which needs to be implemented:
type backend struct{}
func (backend) Jump(in *JumpIn) (*JumpOut, error) {
log.Print(in.Latitude, in.Longitude)
return nil, nil
}
func main() {
server := varlink.NewServer()
server.Handler = Handler{backend{}}
if err := server.Serve(listener); err != nil {
log.Fatal(err)
}
