cortana gives you a new style to write command line programs
Cortana
An extremely easy to use command line parsing library
Features
- Extremely easy to use
- Handling the sub commands exactly the same as the main command
- Parse args from configration file, envrionment and flags
How to use
Work in the main function
// say.go
func main() {
args := struct {
Name string `cortana:"--name, -n, tom, who do you want say to"`
Text string `cortana:"text"`
}{}
// Parse the args
cortana.Parse(&args)
fmt.Printf("Say to %s: %s\n", args.Name, args.Text)
}
$ go run say.go -n alice hello
Say to alice: hello
Use as the sub-command
// pepole.go
func say() {
args := struct {
Name string `cortana:"--name, -n, tom, who do you want say to"`
Text string `cortana:"text"`
}{}
cortana.Parse(&args)
fmt.Printf("Say to %s: %s\n", args.Name, args.Text)
}
func main() {
// Add "say" as a sub-command
cortana.AddCommand("say", say, "say something")
cortana.Launch()
}
$ go run pepole.go say -n alice hello
Say to alice: hello
You defines how the sub-commond looks like without affecting the original implementation
// people.go
func main() {
// say greeting works by calling the say function
cortana.AddCommand("say greeting", say, "say something")
// greeting say also works by calling the say function
cortana.AddCommand("greeting say", say, "say something")
cortana.Launch()
}
$ go run pepole.go say greeting -n alice hello
Say to alice: hello
$ go run pepole.go greeting say -n alice hello
Say to alice: hello
