Using the main.version ldflag¶

By default, GoReleaser will set the following 3 ldflags:

• main.version: Current Git tag (the v prefix is stripped) or the name of the snapshot, if you're using the --snapshot flag
• main.commit: Current git commit SHA
• main.date: Date in the RFC3339 format

You can use them in your main.go file to print more build details:

package main

import "fmt"

var (
    version = "dev"
    commit  = "none"
    date    = "unknown"
)

func main() {
  fmt.Printf("my app %s, commit %s, built at %s", version, commit, date)
}

You can override this by changing the ldflags option in the build section.
