Update Commander version

[Tordek]

dotenv supports passing multiple .env files as an array, but the old version of commander does not support variadic parameters.

Thanks. I have been waiting for this feature my whole life

Thanks for the work @Tordek. Unfortunately it looks like there are many changes in here which are unrelated to .env file loading. That makes it quite hard to review and merge. Would you be up for moving all the other stuff out of this PR?

[Tordek]

It's not really possible. Commander needs to be updated to support the ... syntax, and the API for commander changed:

• new Command() usage.
• program.option was replaced by program.opts().option
• due to ^ some changes where the program accessed program.options at the root of the file need to be moved inside the action, so opts are parsed.

I could remove the redis dev dependency if that's an issue but it's used in the tests, so it's needed.

Ah, thanks for the clarification. Yes I can see how this is related now. In that case, I would recommend doing two prs:

1. update commander
2. add support for multiple .env

That should be easy enough to just remove the variadic from the .env option right?

[Tordek]

Fair enough, I'll do that.
