MarkFlagRequired in cobra seems to have no effect












0















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.

  • @danicheeta Ya. I checked it. It does not throw an error.

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") }
