gover

gover is package version management tool for Go projects.

Instead of manually incrementing the version number in your code (🗿), you can simply use gover to automatically do it. Also, you can use gover to tag the git branch to the current version of your project (using git tag).

Under the hood, gover will read a gover.json file in your project and update the version number accordingly. It will also generate a version.go file that contains the current version number, which you can import in your project.

Installation

$ go install github.com/vanillaiice/gover@latest

Usage

In your Go project, use gover init to initialize the version file:

# create a gover.json & version.go with a default version of v0.0.1
$ gover init
# create a version.json with a version of v1.0.0
$ gover init -v v1.0.0 -f version.json
# create a gover.json with a version of v1.0.0, custom path for the Go output file,
# and a custom package name
$ gover init -v v1.0.0 -o cmd/version.go -P cmd

Then, you can use the version constant in your project:

package cmd

import (
	"log"
	"os"

	"github.com/urfave/cli/v2"
)

// Exec starts the cli app.
func Exec() {
	app := &cli.App{
		Name:                   "gover",
		Usage:                  "package version management tool for Go",
		Version:                version,

here, the version.go file is in the cmd directory.

Finally, you can use gover bump to increment the version number:

# bump to major version (e.g. v1.0.0 -> v2.0.0)
$ gover bump --major
# bump to minor version (e.g. v1.0.0 -> v1.1.0) with verbose log and custom output file
$ gover -V bump --minor -o ver.go
# bump to patch version (e.g. v1.0.0 -> v1.0.1) with custom package name
$ gover bump --patch -P pkg

On a side note, you can also use environment variables to define the package name, version file, and output file:

VERSION_FILE=gover.json
OUTPUT_FILE=cmd/version.go
PACKAGE_NAME=cmd

these values can be defined in a file named .env or .gover.
