flags package: shared flags and flag sets

[Chris Burkert]

Dear all,

I'd like to mix shared flags with flags specific to flag sets (cooltool <globalFlags> <subcommand> <commandFlags>). However I struggle to parse the shared flags only and pass the rest to the flagset for parsing. Here is what I came up with:

https://play.golang.org/p/Jazn3aSX9-d

Do I have to pick a different flag library or can this be done with package flag from the standard library?

Thanks - Chris

See how pkg https://go.dev/github.com/peterbourgon/ff/v3/ffcli does it

https://play.golang.org/p/Sga78gMLn-9

You can then use it like './mycli -d stream -rt'

The '-d' option is a shared flag, and `-rt' is dedicated for the subcommand 'stream'.

Thank you very much.

This is exactly what I was looking for. A simple way without the need for additional packages.

Highly appreciated!

Not sure if it can help, but look at:

https://github.com/perillo/cmd/blob/master/cmd.go

It is adapted from cmd/go subcommand code and use the standard flag package.
