zparseopts - If no argument is given to compulsory option, it takes next option as the argument
 

I am using zsh 5.4.2. The function that is causing issue is:

Output:

You can see that, If I do not pass a value to --watch (which's argument is mandatory) then it takes the next option in this case --show as the argument. It should actually show an error like zp:zparseopts:1: missing argument for option: -watch

Why is --watch taking --show as an argument instead of throwing an error.

zparseopts - How to make an option (not argument of the option) mandatory
 

In The example bellow:
I get the follwing output.
Here the argument of the option is mandatory so I am getting this error.

How can I make the option mandatory so that I must pass --walk to zp else it will throw an error.

zparseopts - How to pass multiple argument to an option
 

In The example bellow:
I get the following output:
So, I have to use the option (--walk) multiple times to insert multiple argument (Walking / Run). Or, I can use double quotation mark to insert multiple argument using one option.

It looks weird if we do something like:
Is there any way I can insert multiple arguments in single option without using double quotation mark.

Something like:

you need to check getopt (and/or getopts) which is used to handle this.
Otherwise you need to check $# (and additionally $1, $2 ....)

see for example: https://dustymabe.com/2013/05/17/eas...a-bash-script/

this is a much better example: https://stackoverflow.com/questions/...d-line-options

What might be the solution with $# & $1, $2 ....?

as far as I see your problem is relatively complex, you need to look for a ready-made solution (like getopt) instead of re-implementing it again.

These are different questions regarding zparseopts. If I open one question with all these queries then no one will even touch these questions because it will be too complicated.

I have checked getopt, getopts & zparseopts. All my problems are solved with zparseopts except these three issues.

Moreover, I have to rewrite a lot of stuff if I try to replace zparseopts now.

The solution that I found is:

I actually realized that it looks perfectly natural to have -f "file1 file2 file3" and very weird to have -f file1 file2 file3. So, I am quiting the pursuit to the answer of this question.
