Go's linker injects string values via -ldflags:

examples/go/main.go

package main

import "fmt"

// VERSION will be set by the linker during build
var VERSION = "0.0.0"

func main() {
    fmt.Printf("Sample Go Application\n")
    fmt.Printf("Version: %s\n", VERSION)
}

examples/go/Makefile (excerpt)

build:
    VERSION=$$(versionator version); \
    go build -ldflags "-X main.VERSION=$$VERSION" -o sample-app .

Run it

$ cd examples/go && just run
