Package::Generator.3pm

NAME

Package::Generator - generate new packages quickly and easily

VERSION

version 0.103

SYNOPSIS

     use Package::Generator;
 
     my $package = Package::Generator->new_package;
     ...
 
 

DESCRIPTION

This module lets you quickly and easily construct new packages. It gives them unused names and sets up their package data, if provided.

INTERFACE

new_package

   my $package = Package::Generator->new_package(\%arg);
 
 

This returns the newly generated package. It can be called with no arguments, in which case it just returns the name of a pristene package. The "base" argument can be provided to generate the package under an existing namespace. A "make_unique" argument can also be provided; it must be a coderef which will be passed the base package name and returns a unique package name under the base name.

A "data" argument may be passed as a reference to an array of pairs. These pairs will be used to set up the data in the generated package. For example, the following call will create a package with a $foo set to 1 and a @foo set to the first ten counting numbers.

   my $package = Package::Generator->new_package({
     data => [
       foo => 1,
       foo => [ 1 .. 10 ],
     ]
   });
 
 

For convenience, "isa" and "version" arguments may be passed to "new_package". They will set up @ISA, $VERSION, or &VERSION, as appropriate. If a single scalar value is passed as the "isa" argument, it will be used as the only value to assign to @ISA. (That is, it will not cause $ISA to be assigned; that wouldn't be very helpful.)

assign_symbols

   Package::Generator->assign_symbols($package, \@key_value_pairs);
 
 

This routine is used by "new_package" to set up the data in a package.

package_exists

   ... if Package::Generator->package_exists($package);
 
 

This method returns true if something has already created a symbol table for the named package. This is equivalent to:

   ... if defined *{$package . '::'};
 
 

It's just a little less voodoo-y.
