Allow global flags after command

[fgblomqvist]

This is just a suggestion, but to me it seems logical to allow global flags after the command as well, not only before it.

For example, if you have a verbose flag, -v:
myapp -v server
vs.
myapp server -v

To me the second one does visually make more sense. Are there cases when this is a bad idea (and therefore the reason to why this is not how it is currently implemented)?

Hi @fgblomqvist, I agree with you completely. Unfortunately this is baggage that we carry from using the Go stdlib flag library (which stops parsing the moment it hits a non-flag) so we cannot support it unless we were to rip that out and do our own flag parsing (which we have discussed a bit, but is a non-trivial effort). You can see some more conversation about this in #355.

I'll leave this open as a future enhancement though!

[fgblomqvist]

Okay, I see.

The core flag package is BSD licensed, so perhaps the easiest fix would be to include a fork of said package, modified to support intermixed arguments/flags. This has the benefit of keeping the API identical, making the integration simpler than a rewrite or using a different 3rd-party package. Does this sound reasonable?

[jszwedko]

@noffle mmm, that is not a bad idea given the tradeoffs. I'll try to give that a shot in the near future.

Thank you for the suggestion!

Also interested in this.

[nikkolasg]

Bump up for this one too !
But in the meantime, @jszwedko : Thank you so far for the good job you've done ;)

[marwan-at-work]

wondering if this issue is still up for a fix :)

[coilysiren]

Given that this is from last year, I think I'm comfortable closing it 🙂 feel free to re-open / open a new issue / comment in support if there's still interest here!

[coilysiren]

Oh!!! I just noticed there's 22 👍s. Re-opening now 📈

[coilysiren]

This may have been fixed by v2? I'd appreciate if someone could investigate that 🙏

I loved cli library before but this issue of not able to inter-mix arguments and flags is a bit problematic.

To make things worse, certain earlier version used a reordering hack (see above "hack to sidestep #427" which I kind of liked) but this change was later reverted, causing the behavior to vary greatly between versions. I understand that there are bugs regarding this both ways, but the Unix-y default should always be allowing mixing.

I had to track down bugs where cli are suddenly not able to extract flag values where earlier versions worked. Switching to cobra for now.

I don't think that this was fixed in v2, I also don't think that "local" flags are supported after the first non-flag

[coilysiren]

I don't think that this was fixed in v2

Then this issue is available for anyone to work on 👍

This is a great idea! We should definitely have this

[dearchap]

Okay this feature is confirmed for v3. I'd like more feedback on this. Say we define a flag for top level command

./app -v cmd1
./app cmd1 -v

We expect both of these to behave the same. Does this work for subcmd as well i.e if a flag is defined for a cmd it should be available for subcmds as well ?

./app cmd1 --foo subcmd1
./app cmd1 subcmd1 --foo

However

./app --foo cmd1 subcmd1

shouldnt work.

Do we want to specifically list flags as "global" so that only those can be strewn throughout the cmdline. So for example if we define two flags f1 and f2 with f2 marked as "global"

./app cmd1 subcmd1 --f2
./app cmd1 --f2 subcmd1 
./app --f2 cmd1 subcmd1

should all work but not

./app cmd1 subcmd1 --f1
./app cmd1 --f1 subcmd1
