Issue passing local flag to subcommand #1825
Description
I have a root command with persistent flag and a subcommand with a local flag. When executing subcommand, I seem to be unable to pass the local flag. No matter how I do it, I get Error: unknown flag:.
Here's the minimal example that reproduces my situation:
package main
import (
"fmt"
"github.com/spf13/cobra"
)
var (
testFlag string
subFlag bool
rootCmd = &cobra.Command{
Use: "root",
}
)
func init() {
rootCmd.PersistentFlags().StringVar(&testFlag, "rootFlag", "", "")
subCmd := &cobra.Command{
Use: "subcommand",
}
subCmd.LocalFlags().BoolVar(&subFlag, "subFlag", false, "")
subCmd.RunE = func(cmd *cobra.Command, args []string) error {
fmt.Println(testFlag)
fmt.Println(subFlag)
return nil
}
rootCmd.AddCommand(subCmd)
}
func main() {
rootCmd.Execute()
}
All of the above invocations produce an error Error: unknown flag: --subFlag:
$ go run . subcommand --rootFlag blah --subFlag
$ go run . subcommand --subFlag --rootFlag blah
$ go run . --rootFlag blah subcommand --subFlag
Can someone please explain me what am I missing here?
