Alias for flags ?

[vdesabou]

Hello,

I'm using --alias for commands, and i think it would be useful to be able to do the same for flags, as I understand it is not possible right now.

Example:

My CLI supports a command with container and has alias for pod. I have a flag --container for which I would like to set an alias to --pod

Would that make sense ?

My first reaction is that it does make sense, but it might not be as easy or straight forward.
For one thing, what would the alias define? long or short? Or would it allow an array of aliases?

long: --container
short: -c
alias: [--pod, -p]

[vdesabou]

array of aliases would be perfect indeed :)

I think it can be added easily. I have started a codex session, I hope I can get it into a 1.4.0.rc3 version today or tomorrow.

For the help string, I am thinking of simply showing all the options:

--container, -c, --pod, -p NAME
   Help string here

instead of

--container, -c NAME
   Help string here
   Aliases: --pod, -p

If you have any strong opinion one way or the other, let me know - I am open to both options, but the first is slightly easier (no custom strings involvement, easier for usage texts on error etc)

Created #716

Added in #717.

Are you able to test from source, or do you require a pre-release gem?

[vdesabou]

yes i was able to test and it works like a charm :)

playground pod exec --help

...

== Options ==
  --container, -c, --pod, -p CONTAINER (repeatable)
 ...

I use your docker image dannyben/bashly so I'm looking forward to get 1.4.0 on the hub !

thanks for your quick implementation, this is amazing !

Sure thing, thanks for the feature request.

I am just now adding negatable flags (--[no-]color) and I think I am ready for release. Hopefully today or tomorrow at most.
