cobra-update

Provides a cobra command to allow your apps to self-update themselves by downloading the latest GitHub release.

Setup

1. Add the command to your Cobra app, passing in the owner/repo where new releases will be downloaded from:

   import update "github.com/Shamus03/cobra-update"
   
   func init() {
       rootCmd.AddCommand(update.Command("Shamus03", "munn"))
   }

2. (optional) Make sure your root *cobra.Command has its Version field set. This is the most simple example:

   var rootCmd = &cobra.Command {
       Use: "your-command",
       // other fields
       Version: "1.2.3",
   }

   • Skipping this step will cause the update command to always download the latest release, even if the executable is already up to date.
   • For a more complex example of setting the version through an automated workflow at build time, see munn's version file and semantic-release configuration.
