In golang, can I use the flag package to define a flag that optionally accepts a string argument?

Question content

What I want to do is be able to run these three scenarios:

cmd --test --branchrelease

cmd --test all --branch release

cmd --branch release

You can specify --test yourself without parameters (such as Boolean values), and you can also specify parameters.

I don't think this is possible because the next flag (--branch) is used as an argument to --test when no arguments are given, but I thought I'd ask in case I'm missing something . p>

Correct Answer

No, there is no such option.
