UpgradeCLI

Join #upgrade-cli on Discord

UpgradeCLI makes it easy to add an upgrade command to your cli.

UpgradeCLI was built to implement the upgrade command for Savvy's OSS CLI.

Savvy's CLI helps developers create and share high quality runbooks right from the terminal.

Install

go get github.com/getsavvyinc/upgrade-cli

Usage

package cmd

import (
	"context"
	"os"

	"github.com/getsavvyinc/savvy-cli/config"
	"github.com/getsavvyinc/savvy-cli/display"
	"github.com/getsavvyinc/upgrade-cli"
	"github.com/spf13/cobra"
)

const owner = "getsavvyinc"
const repo = "savvy-cli"

// upgradeCmd represents the upgrade command
var upgradeCmd = &cobra.Command{
	Use:   "upgrade",
	Short: "upgrade savvy to the latest version",
	Long:  `upgrade savvy to the latest version`,
	Run: func(cmd *cobra.Command, args []string) {
		executablePath, err := os.Executable()
		if err != nil {
			display.Error(err)
			os.Exit(1)
		}
		version := config.Version()

		upgrader := upgrade.NewUpgrader(owner, repo, executablePath)

		if ok, err := upgrader.IsNewVersionAvailable(context.Background(), version); err != nil {
			display.Error(err)
			return
		} else if !ok {
			display.Info("Savvy is already up to date")
			return
		}

		display.Info("Upgrading savvy...")
		if err := upgrader.Upgrade(context.Background(), version); err != nil {
			display.Error(err)
			os.Exit(1)
		} else {
			display.Success("Savvy has been upgraded to the latest version")
		}
	},
}

func init() {
	rootCmd.AddCommand(upgradeCmd)
}
