How do I generate shell completions using urfave/cli in Go?

In Go, you can generate shell completions using the urfave/cli package to enhance your command-line applications. This feature greatly improves usability by allowing users to easily complete their commands during terminal usage.

Here is a simple example demonstrating how you can implement shell completion in your application:

package main import ( "github.com/urfave/cli/v2" "os" ) func main() { app := &cli.App{ Name: "myapp", Usage: "This is my sample app", Commands: []*cli.Command{ { Name: "serve", Usage: "Start the server", }, { Name: "deploy", Usage: "Deploy the application", }, }, Action: func(c *cli.Context) error { return c.App.Run(os.Args) }, } // Enable shell completions app.EnableShellCompletion = true err := app.Run(os.Args) if err != nil { os.Exit(1) } }
