|
}
|
|
|
|
func (c *exampleCommand) Name() string {
|
|
return "example"
|
|
}
|
|
|
|
func (c *exampleCommand) Usage() string {
|
|
return "just example command"
|
|
}
|
|
|
|
func (c *exampleCommand) Flags() *flag.FlagSet {
|
|
fs := flag.NewFlagSet(c.Name(), flag.ExitOnError)
|
|
fs.StringVar(&c.test, "test", "value", "test flag")
|
|
return fs
|
|
}
|
|
|
|
func (c *exampleCommand) Run(args []string) error {
|
|
fmt.Printf("Runned %s command with flag -test=%s and args: %v", c.Name(), c.test, args)
|
|
return nil
|
|
}
|
|
```

func main() {
|
|
app := app.New([]app.Command{
|
|
exampleCommand{}, // <- Register command
|
|
})
|
|
