MarkFlagRequired in cobra seems to have no effect
I am trying to add a required flag in cobra and I have the a sample code below.
package commands
import (
"github.com/spf13/cobra"
)
var sampleCommand = &cobra.Command{
Use: "sample",
Run: func(ccmd *cobra.Command, args string) {
fmt.Println("Hello World")
},
}
func init() {
sampleCommand.Flags().StringP("something", "s", "", "something")
sampleCommand.MarkFlagRequired("something")
}
And I am testing this by
func TestSomething(t *testing.T) {
err := sampleCommand.Execute()
if err != nil {
t.Fail()
}
}
And I do not see any errors. Am I missing something?
EDIT :
I was using an earlier version of cobra which probably had this bug. I upgraded to the HEAD and I no longer see this issue.
go cobra

You didn't get any error because your simpleCommand
is not runnable. A command is runnable, if following is true (ref:here) :
// Runnable determines if the command is itself runnable.
func (c *Command) Runnable() bool {
return c.Run != nil || c.RunE != nil
}
As your simpleCommand
does not define any Run
or RunE
, your command is not runnable and that's why you didn't get any error. Define Run
or RunE
, you will get the required flag error.
var sampleCommand = &cobra.Command{
Use: "sample",
Run: func(cmd *cobra.Command, args string) {
fmt.Println("here")
return
},
}
In my original code I do have a Run element. I had abstracted it out here and hence did not add the Run part. I changed the code accordingly, but I still don't see any error func RunSomething(ccmd *cobra.Command, args string) { fmt.Println("Hello World") }
