Editing Advice (programming) (section)

==Implementations==
A form of advices were part of [[C with Classes]] in the late 1970s and early 1980s, namely functions called <code>call</code> and <code>return</code> defined in a class, which were called before (respectively, after) member functions of the class. However, these were dropped from [[C++]].<ref>''The Design and Evolution of C++,'' p. 57</ref>

Advices are part of the [[Common Lisp Object System]] (CLOS), as <code>:before</code>, <code>:after</code>, and <code>:around</code> methods, which are combined with the primary method under "standard method combination".<ref>{{Cite web |url=http://www.aiai.ed.ac.uk/~jeff/clos-guide.html |title=A Brief Guide to CLOS |access-date=2015-04-27 |archive-url=https://web.archive.org/web/20150506043702/http://www.aiai.ed.ac.uk/~jeff/clos-guide.html |archive-date=2015-05-06 |url-status=dead }}</ref>

Common Lisp implementations provide advice functionality (in addition to the standard method combination for CLOS) as extensions. LispWorks<ref>[http://www.lispworks.com/documentation/lw70/LW/html/lw-32.htm LispWorks 7 User Guide and Reference Manual, The Advice Facility]</ref> supports advising functions, macros and CLOS methods.

EmacsLisp added advice-related code in version [http://web.mit.edu/dosathena/sandbox/emacs-19.28/src/ChangeLog 19.28], 1994.
