Argument

User defined attribute for a positional argument.

struct Argument {

size_t lowerBound;

size_t upperBound;

this(string name, size_t count = 1);

this(string name, size_t lowerBound, size_t upperBound);

this(string name, Multiplicity multiplicity);

string usage [@property getter];

size_t multiplicityError [@property setter];

}

Constructors

this this(string name, size_t count = 1): Constructs an argument with the given name and count. The count specifies how many argument elements should be consumed from the command line. By default, this is 1.
this this(string name, size_t lowerBound, size_t upperBound): Constructs an argument with the given name and an upper and lower bound for how many argument elements should be consumed from the command line.
this this(string name, Multiplicity multiplicity): An argument with a multiplicity specifier.

Members

Properties

multiplicityError size_t multiplicityError [@property setter]: Get a multiplicity error string.
