[Golang] 编译程序时打上git提交信息标记

1、加入代码

//version.go

package version

import (
    "flag"
    "fmt"
    "os"
)

var (
    BuildVersion = "0.0"
    BuildTime    = "0"
    CommitID     = "xxxxx"
)

func Parse() {
    var showVer bool
    flag.BoolVar(&showVer, "v", false, "show build version")

    flag.Parse()

    if showVer {
        fmt.Printf("build ver:	%s
", BuildVersion)
        fmt.Printf("build time:	%s
", BuildTime)
        fmt.Printf("Commit ID:	%s
", CommitID)
        os.Exit(0)
    }
}

2、Makefile

BUILD_VERSION   := $(SERVER_VERSION)
BUILD_TIME      := $(shell date "+%F %T")
COMMIT_SHA1     := $(shell git rev-parse HEAD )

all myapp

myapp:
    go build -gcflags "-N -l" 
    -ldflags                                    
    "                                           
    -X 'version.BuildVersion=${BUILD_VERSION}'  
    -X 'version.BuildTime=${BUILD_TIME}'        
    -X 'version.CommitID=${COMMIT_SHA1}'        
    "                                           
    myapp

3、make

4、查看

./myapp -v
