Application auto build versioning

Question

Is it possible to increment a minor version number automatically each time a Go app is compiled?

I would like to set a version number inside my program, with an auto

Answer 1

On Windows OS given the program below

package main

import "fmt"

var (
    version string
    date    string
)

func main() {
    fmt.Printf("version=%s, date=%s", version, date)
}

You can build using

go build -ldflags "-X main.version=0.0.1 -X main.date=%date:~10,4%-%date:~4,2%-%date:~7,2%T%time:~0,2%:%time:~3,2%:%time:~6,2%"

Date format assumes your environment echo %date% is Fri 07/22/2016 and echo %time% is 16:21:52.88

Then the output will be: version=0.0.1, date=2016-07-22T16:21:52
