gocmd's Issues

Flag value same as subcommand name result in error

Here is another bug I found

Minimal example:

package main

import (
	"log"
	"github.com/devfacet/gocmd"
)

func main() {
	flags := struct {
		Command struct {} `command:"command"`
		Flag string `short:"f" long:"flag" required:"true"`
	}{}

	_, err := gocmd.New(gocmd.Options{
		Flags:       &flags,
		AnyError:    true,
	})

	if err != nil {
		log.Fatal(err)
	}
}

When running:

# bug -f command
argument -f needs a nonempty value

# bug -f "command"
argument -f needs a nonempty value

# bug -f other

Error when running same flag in different sub-commands

When running same flag short/long name in different sub-commands I get the following error:

short argument n in Name field is already defined in Name field

This is some code triggering the error.

Create struct {
	Python struct {
		Name string `short:"n"`
	} `command:"python"`
	Golang struct {
		Name string `short:"n"`
	} `command:"golang"`
} `command:"create"`

Also when giving them different short flag (like m and n) the auto help puts then in the same context:

create
    python         
    golang         
      -m, --mame   
      -n, --name   

I would expect it to be possible to use the same flags within different sub-commands. Bug or by design?

Edit: Added auto-help output.
