NAME

Aspect-Oriented Perl - Aspect-oriented programming in pure Perl

DESCRIPTION

Introduction to AOP

Aspect-oriented Programming (AOP) is a programming methodology developed by Xerox PARC. The basic idea is that in complex class systems there are certain aspects or behaviors that cannot normally be expressed in a coherent, concise and precise way. One example of such aspects are design patterns, which combine various kinds of classes to produce a common type of behavior.

Aspects in Perl provide:

  • Dynamic enabling and disabling of aspects at run-time

  • Modular aspects for prepackaged functionality

See Aspect::Intro for an introduction to aspect-oriented programming. See Aspect::Overview for an overview of the modules and classes that comprise this distribution. See Aspect::Ideas for ideas on future developments. See Aspect::Cookbook for aspect-oriented recipes for common situations. See the individual modules' manpages for information on how to use and implement aspects.

LIMITATIONS

  • Many types of join points and pointcuts remain unimplemented.

  • Performance may suffer for aspects affecting a wide range of join points.

PREREQUISITES

Aspect requires the following modules, which can be obtained from CPAN:

Class::MethodMaker
Hook::LexWrap
IO::Scalar

If you install Aspect from the CPAN shell, these modules will, if necessary, be installed automatically as well.

INSTALLATION

It's all pure Perl, so just put the .pm files in their appropriate local Perl subdirectories.

The easiest way to install this distribution is using the standard build process for Perl modules:

perl Makefile.PL
make
make test
make install

Or you could use the CPAN shell, as described in the CPAN module documentation.

CHANGES AND FUTURE DEVELOPMENT

This README refers to version 0.04. For details of changes, refer to the file Changes.

Future versions will provide new types of join points, pointcuts and modular aspects. Stability and performance is also an ongoing concern. See Aspect::Ideas for an overview of these ideas.

CHANGES IN VERSION 0.04

  • Added documentation

AVAILABILITY

Aspect has been uploaded to the CPAN; in any case it is available from:
