Editing Software design pattern (section)

==History==

Patterns originated as an [[Pattern (architecture)|architectural concept]] by [[Christopher Alexander]] as early as 1977 in [[A Pattern Language]] (cf. his article, "The Pattern of Streets," JOURNAL OF THE AIP, September, 1966, Vol. 32, No. 5, pp.&nbsp;273–278). In 1987, [[Kent Beck]] and [[Ward Cunningham]] began experimenting with the idea of applying patterns to programming – specifically [[pattern language]]s – and presented their results at the [[OOPSLA]] conference that year.<ref name = "Smith1987">{{cite conference

| quote=Ward cautioned against requiring too much programming at, what he termed, 'the high level of wizards.' He pointed out that a written 'pattern language' can significantly improve the selection and application of abstractions. He proposed a 'radical shift in the burden of design and implementation' basing the new methodology on an adaptation of Christopher Alexander's work in pattern languages and that programming-oriented pattern languages developed at [[Tektronix]] has significantly aided their software development efforts.}}</ref><ref name = "Beck1987">{{cite conference

Design patterns gained popularity in [[computer science]] after the book [[Design Patterns|''Design Patterns: Elements of Reusable Object-Oriented Software'']] was published in 1994 <!-- 1994, not 1995. See talk page. --> by the so-called "Gang of Four" (Erich Gamma, Richard Helm, Ralph Johnson and John Vlissides), which is frequently abbreviated as "GoF". That same year, the first [[Pattern Languages of Programming]] Conference was held, and the following year the [[Portland Pattern Repository]] was set up for documentation of design patterns. The scope of the term remains a matter of dispute. Notable books in the design pattern genre include:

Although design patterns have been applied practically for a long time, formalization of the concept of design patterns languished for several years.<ref name = "Baroni2003">{{cite report
