goversionflag

goversionflag is an go package aiming to help identifying versions of deployed go binarys.

Installation

go get -u github.com/stockholmuniversity/goversionflag

Usage

package main

import (
        "fmt"
        "github.com/stockholmuniversity/goversionflag"
)

func main() {
        goversionflag.PrintVersionAndExit()
        fmt.Println("End of program, will not be shown when run with '-version'")
}

Build your program

When building your program with goversionflag you must add buildflags in the build process:

go build -ldflags "-X github.com/stockholmuniversity/goversionflag.projectName=$project -X github.com/stockholmuniversity/goversionflag.gitCommit=$commit -X github.com/stockholmuniversity/goversionflag.buildTime=$time"

If you are using a vendoring system, for example dep that puts all dependency's in an vendoring directory you must use the full path name relative to $GOPATH as described in issue

go build -ldflags "-X ${MYPROJECT}/vendor/github.com/stockholmuniversity/goversionflag.projectName=$project -X ${MYPROJECT}/vendor/github.com/stockholmuniversity/goversionflag.gitCommit=$commit -X ${MYPROJECT}/vendor/github.com/stockholmuniversity/goversionflag.buildTime=$time"
