Modules
Learn about the modules in Perl.
Overview
We’ve seen functions, classes, and data structures used to organize code.
Perl’s next mechanism for organization and extension is the module. A module
is a package contained in its file and loadable with use
or require
. A module
must be valid Perl code. It must end with an expression that evaluates to a
true value so that the Perl parser knows it has loaded and compiled the
module successfully.
There are no other requirements—only strong conventions.
