The space is throwing off perl. But you DONT NEED to map every city name... if it's not in the hash array, the script will simply capitalize the first letter and take the rest. So:
Code:
berkeley => 'Berkeley', Vallejo => 'Vallejo'
are also not needed. However this IS needed (just in case):
There is an error when i am trying to use the shift command in this way:
($1 = -d, $2 = 123, $3 = -c etc etc)
for $arg in $@
do
case $arg in
"-d") shift; (so that the $2 will become the $arg now)
(and while it loop the 2nd time,)

Hi Folks,
In shell scripting the maximum no. of command line parameters becomes 9(Am i right). If we want to get more than 9 parameters we use the shift command.
Even here there are two possibilities.
1. Without the use of variables - The arguments are lost and the lost no. is equal to the... (6 Replies)

Hey all, I need some assistance. I'm writing a script to eject tapes from a tape library, but the library is not a queued system and can only eject 15 tapes at a time.

I am new to Perl and I am having some issues getting a script to work. I have to create a script that uses an array of 52 cards, "shuffles" the cards (using loops with the pop, shift, and push commands), and prints out the top five. This is not a randomizing of the array just a... (2 Replies)

moose::meta::typeconstraint::union
Moose::Meta::TypeConstraint::Union(3) User Contributed Perl Documentation Moose::Meta::TypeConstraint::Union(3)NAME
Moose::Meta::TypeConstraint::Union - A union of Moose type constraints
VERSION
version 2.1202
DESCRIPTION
This metaclass represents a union of type constraints. A union takes multiple type constraints, and is true if any one of its member
constraints is true.
INHERITANCE
"Moose::Meta::TypeConstraint::Union" is a subclass of Moose::Meta::TypeConstraint.
Moose::Meta::TypeConstraint::Union->new(%options)
This creates a new class type constraint based on the given %options.
It takes the same options as its parent. It also requires an additional option, "type_constraints". This is an array reference
containing the Moose::Meta::TypeConstraint objects that are the members of the union type. The "name" option defaults to the names all
of these member types sorted and then joined by a pipe (|).
The constructor sets the implementation of the constraint so that is simply calls "check" on the newly created object.
Finally, the constructor also makes sure that the object's "coercion" attribute is a Moose::Meta::TypeCoercion::Union object.
$constraint->type_constraints
This returns the array reference of "type_constraints" provided to the constructor.
$constraint->parent
This returns the nearest common ancestor of all the components of the union.
$constraint->check($value)
$constraint->validate($value)
These two methods simply call the relevant method on each of the member type constraints in the union. If any type accepts the value,
the value is valid.
With "validate" the error message returned includes all of the error messages returned by the member type constraints.
$constraint->equals($type_name_or_object)
A type is considered equal if it is also a union type, and the two unions have the same member types.
$constraint->find_type_for($value)
This returns the first member type constraint for which "check($value)" is true, allowing you to determine which of the Union's member
type constraints a given value matches.
$constraint->is_a_type_of($type_name_or_object)
This returns true if all of the member type constraints return true for the "is_a_type_of" method.
$constraint->is_subtype_of
This returns true if all of the member type constraints return true for the "is_a_subtype_of" method.
$constraint->create_child_type(%options)
This returns a new Moose::Meta::TypeConstraint object with the type as its parent.
