NAME¶
Package::Generator - generate new packages quickly and easily
VERSION¶
version 1.106
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.
