Switches with zero or more arguments

[Zorgle]

I was considering modifying the switch code to allow being able to specify a switch as taking zero or more arguments.

For example, allow either of the following to specifically set the polling option from the command line

• "program -Polling"
• "program -Polling on"

and allow the following to turn it off from the command line:

• "program -Polling off"

It is going to be tricky to add new overrides to the Switch constructor, because there are already so many, and so many combinations of parameters, so I was considering just adding a static Switch constructor for this, eg,

• "static Switch Switch:CreateOptionalArgs(string name, int minArgCount, int maxArgCount, bool isRequired)"

(I'm omitting the other parameters for simplicity of discussion.)

I would then convert "m_hasArguments" into "m_minArguments" and "m_maxArguments", and use UnknownNumberArguments for unspecified max parameter count (as it is currently).

Thoughts?

I understand what you're trying to achieve, but would say that it isn't really necessary and is more of a "nice to have" enhancement. Adding this would require a bit of redesign as, like you mentioned, there are already many Switch class constructors and the current design calls for a Switch class instance to either have no arguments or at least one, but not zero or more.

We can leave this as an enhancement as there is a valid use case, but it can be worked around at the moment and is not critical to add.

I wound up taking a different library in which I could do the argument-less options (as outlined above) that I needed, so this doesn't matter to me anymore. Feel free to close it.

Which library did you end up using? Might be good to refer to it later if this enhancement ends up being added at some point.
