The '''Portland Pattern Repository''' ('''PPR''') is a repository for [[design pattern (computer science)|computer programming design pattern]]s. It was accompanied by a companion website, [[WikiWikiWeb]], which was the world's first [[wiki]].

The '''Portland Pattern Repository''' ('''PPR''') is an online repository for [[computer programming]] [[software design pattern]]s. It was accompanied by the website [[WikiWikiWeb]], the world's first [[wiki]]. The repository has an emphasis on [[Extremeextreme Programmingprogramming]]., Itand is hosted by Cunningham & Cunningham (C2) of [[Portland, Oregon]].<ref>{{cite web|title=Portland atPattern Repository|url=http://c2.com/ppr/.|website=c2.com|access-date=12 July 2017}}</ref> The PPR's [[motto]] is "[http://c2.com/cgi/wiki?PeopleProjectsAndPatterns People, Projects & Patterns]"."

== History ==

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

Cunningham & Cunningham, the programming [[Consultant|consultancy]] whichthat would eventually host the PPR on its Internet ___domain, was incorporated in [[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]], a collection of reader-modifiable Web pages, which is named [[WikiWikiWeb]].<ref>{{cite web|title=Wiki Wiki Web|url=http://wiki.c2.com/?WikiWikiWeb|website=wiki.c2.com|access-date=13 July 2017}}</ref>
