Not specifying these options implies that you should specify all options listed in "absenceImplications".
e.g. if the user does not specify "vacation" then they must specify --job and --hours
Aliases for your option. These allow the user to specify the option with a shorter or otherwise alternate name e.g. name: "puppy", aliases: ["p", "pup"] - the user can specify --puppy, -p, or --pup
What values can be specified for this option? See the type below for more details.
If the type is array, this option defines if duplicate values in array are allowed. Default is true.
Defines which options this one conflicts with.
If the user doesn't specify this option, you can specify a default value here that will be filled in automatically.
The description of your option - displayed in the help text for your command.
The group/category for this option. Options with the same group on the same command are grouped together under a heading with this text.
Option is hidden from help
If this option is specified, all options whose name appear in the "implies" field must also be specified. e.g. if this option is "vacation", and ["seat", "meal"] is the value for "implies", then the user will get a syntax error if they specify --vacation but not --seat and --meal
If this option is specified, at least one of the options whose name appear in the "impliesOneOf" field must also be specified. e.g. if this option is "vacation", and ["seat", "meal"] is the value for "impliesOneOf", then the user will get a syntax error if they specify --vacation but not either --seat or --meal
The canonical/primary name for your option. This is the first form of the option shown to the user and is generally how you should refer to your option in documentation and programmatically.
Note: yargs automatically places the values for --hyphenated-options in a camelCase format after parsing the command line arguments, so you would be able to access params.arguments.hyphenatedOptions from your handler as well as params.arguments["hyphenated-options"]'
Acceptable value range for number type options. the first number is the minimum. the second is the maximum So the value specified by the user must be min <= value <= max
Is this option required? If it's required and the user does not specify it, they will get a syntax error.
Note: if you give a defaultValue to an option, it will always be considered to have been specified.
Acceptable length range for string type options. the first number is the minimum. the second is the maximum So the length specified by the user must be min <= length <= max
What type of value will the user specify for this option?
If the user specifies a certain value for this option, then they must also specify other options (similar to a conditional "implies")
