Is there a way to call the Go tools (like go build) programmatically from within another Go program with a library call and to get more structured output compared to the text output from the command line invocation?

If you're trying to run build programmatically you can also use the os/exec package.

func runBuild() {
    cmd := exec.Command("go", "build", "./main.go")
    err := cmd.Run()
    if err != nil {
        log.Fatal(err)
    }

}

You can pass other flags too. E.g: the buildmode flag

cmd := exec.Command("go", "build", "-buildmode=plugin", "./main.go")
