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 [[extreme programming]], and is hosted by Cunningham & Cunningham (C2) of [[Portland, Oregon]].<ref>{{cite web|title=Portland Pattern Repository|url=http://c2.com/ppr/.|website=c2.com|access-date=12 July 2017}}</ref> The PPR's [[motto]] is "People, Projects & Patterns".<br />
<br />
== History ==<br />
On 17 September 1987, programmer [[Ward Cunningham]] 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|access-date=12 July 2017}}</ref> This paper, about software 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 and Beck's idea became popular among programmers because it helped them exchange programming ideas in an easy to understand format.<br />
<br />
Cunningham & Cunningham, the programming [[Consultant|consultancy]] that 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><br />
