The '''Portland Pattern Repository''' ('''PPR''') is a repository for [[Software design pattern|computer programming [[software design pattern]]s. It was accompanied by a companion website, [[WikiWikiWeb]], which was the world's first [[wiki]]. The repository has an emphasis on [[Extreme Programming]], and it is hosted by Cunningham & Cunningham (C2) of [[Portland, Oregon|Portland]], Oregon.<ref>{{cite web|title=Portland Pattern Repository|url=http://c2.com/ppr/.|website=c2.com|accessdate=12 July 2017}}</ref> The PPR's [[motto]] is "People, Projects & Patterns".

==History==

On 17 September 1987, programmer [[Ward Cunningham]], then with [[Tektronix]], and [[Apple Computer]]'s [[Kent Beck]] co-published the paper "Using Pattern Languages for Object-Oriented Programs"<ref name="uplfoop">{{cite web|title=Using Pattern Languages for Object-Oriented Programs|url=http://c2.com/doc/oopsla87.html|website=c2.com|accessdate=12 July 2017}}</ref> This paper, about programmingsoftware design patterns, was inspired by [[Christopher Alexander]]'s architectural concept of "patterns"<ref name="uplfoop"></ref> It was written for the 1987 [[OOPSLA]] programming conference organized by the [[Association for Computing Machinery]]. Cunningham and Beck's idea became popular among programmers, because it helped them exchange programming ideas in a format that is easy to understand.

Cunningham & Cunningham, the programming consultancy that would eventually host the PPR on its Internet ___domain, was incorporated in [[Salem, Oregon|Salem]], Oregon on 1 November 1991, and is named after Ward and his wife, Karen R. Cunningham, a mathematician, school teacher, and school director. Cunningham & Cunningham registered their Internet ___domain, ''c2.com'', on 23 October 1994.

Ward created the Portland Pattern Repository on ''c2.com'' as a means to help [[object-oriented programming|object-oriented programmers]] publish their computer programming patterns by submitting them to him. Some of those programmers attended the [[OOPSLA]] and [[PLoP]] conferences about object-oriented programming, and posted their ideas on the PPR.

The PPR is accompanied, on ''c2.com'', by the first ever [[wiki]]&mdash;a collection of reader-modifiable Web pages&mdash;which is called [[WikiWikiWeb]].<ref>{{cite web|title=Wiki Wiki Web|url=http://wiki.c2.com/?WikiWikiWeb|website=wiki.c2.com|accessdate=13 July 2017}}</ref>
