Hi @o1egl

Can you give a little info as to why you might need an uppercase version that the lowercase version doesn't already support?

Also, go ahead and merge master into your fork. That should make the build work on circle. Sorry about that!

[o1egl]

My case is opposite to the case where you need lowercase param. Enums are defined in lowercase and now I also need to support uppercase aliases.

Hi @o1egl

After looking back at the code base, it seems that my implementation of the lower flag was supposed to provide case insensitive lookups for users, not simply to provide a lower case alias of them. Would modifying the parse function to lookup both lowercase and original value suffice for your use case? Or do you need an uppercase variant included with nothing allowed in between?

[o1egl]

I'm fine having case insensitive lookup option. But let's rename it from --lower to --case-insensitive or something similar.

[abice]

I don't want to break things that are already out there in the world, so renaming isn't something I'm fond of, but we can surely add an alias that makes more sense and does the same thing as --lower.

Finally created a new flag: #45

@o1egl Let me know if that will solve your problem!

[o1egl]

Yes, I think we can close this PR
