flag redefined crash

[brunetto]

Hi all!

I'm using the great Cobra (https://github.com/spf13/cobra) package to implement subcommands in my (little) code.

I have two questions, the first is more Cobra-related (I didn'f find a cobra google group) and the second more general:

First question:

--------------------

* I have (for example) two subcommands A and B and the A subcommand include some functions and the function called by B

* Thus A and B need to share some flags

* I can't attach the same flags to two different subcommands otherwise my program will crash with  `panic: <B> flag redefined: <flag name>

This is also described in https://code.google.com/p/go/issues/detail?id=298 and http://golang.org/src/pkg/flag/flag.go

I can agree that using the same flag with different meanings in different context can be confusing, but the same flag with the same meaning

shouldn't be a problem. Moreover, now I have to put the flags as persistent and attach them to the root command and I

don't think this is a great solution because I am linking flags with a command (the root one) that doesn't need them.

Is there a better solution?

Second question:

-------------------------

Why is not possible to check for redefined flags at compile time (given that they are written in the source) instead of crash 

at run time?

thanks a lot

How is that possible?

It seems that I made a mistake and if I separate the flags in different subcommands it works!

I'm sorry.

However I'm still asking myself if it is possible to catch flag errors at compile time.
