Same flag in different groups that created by MarkFlagsRequiredTogether not work as expected

[aegoroff]

Hi all!

I would like to have different groups that created using option MarkFlagsRequiredTogether with the same flag. I.e. I would like to have this:

rootCmd.MarkFlagsRequiredTogether("cpuprofile","diag")
rootCmd.MarkFlagsRequiredTogether("memprofile", "diag")

to run memory or cpu profiling independently, like this:

--diag --memprofile

or

--diag --cpuprofile

or even altogether like this:

--diag --memprofile --cpuprofile

but independent run failed with

Error: if any flags in the group [cpuprofile diag] are set they must all be set; missing [cpuprofile]

Thanks for the report @aegoroff. Your usecase does makes sense to me, but the flag group feature does not support such a case 😞

If you specify MarkFlagsRequiredTogether() then if any of the specified flags is present on the command-line, then all others must be present also.

Thank you for reply!

If you specify MarkFlagsRequiredTogether() then if any of the specified flags is present on the command-line, then all others must be present also.

Sure, so you cannot share an option among different groups. If so you have to use all options from all touched groups :(

It seems that MarkFlagsRequiredTogether call should create different groups that should be validated independently no matter a group option shared with another group or not
