AspectScheme -- Aspects in Higher-Order Languages

This directory contains the code for various releases of AspectScheme. The version 1 release implements the language comprising the Science of Computer Programming; and version 2 release implement the enhanced version alluded to in that paper.

A new release, AspectScheme 4, compatible with PLT Scheme 4 is now available. It is a plug-in language that can be selected from the "Choose language" option, in two levels:

• base which includes three aspect scopes:
  • around
  • fluid-around
  • top-level-around
  and the fundamental pointcuts:
  • target
  • args
  • call?
  • exec?
  • adv?
• full which includes additional aspect combinations:
  • before
  • after
  • after-throwing
  • after-returning
  for each scope, implemented using higher-order advice; and an extended set of pointcuts, including:
  • call
  • exec
  • adv
  • cflowtop
  • cflowbelow
  • cflowabove
  • cflowbottom
  • within
  and pointcut combinators:
  • &&
  • ¦¦
  • !

Most users should probably rely on the PLaneT Package Repository to obtain this code. The various versions are accessible from your PLT Scheme platform via
(require (planet "aspect-scheme.ss" ("cdutchyn" "aspect-scheme.plt" 1 1)))
or
(require (planet "aspect-scheme2.ss" ("cdutchyn" "aspect-scheme.plt" 2 1)))
depending on the desired version.
