==Support in programming languages==

Extension methods are features of numerous languages including [[C Sharp (programming language)|C#]], [[Java (programming language)|Java]] via [http://manifold.systems/docs.html#the-extension-manifold Manifold] or [https://projectlombok.org/features/experimental/ExtensionMethod Lombok] or [https://github.com/rogerkeays/fluent Fluent], [[Gosu (programming language)|Gosu]], [[JavaScript]], [[Oxygene (programming language)|Oxygene]], [[Ruby (programming language)|Ruby]], [[Smalltalk]], [[Kotlin (programming language)|Kotlin]], [[Dart (programming language)|Dart]], [[VB.NET|Visual Basic.NET]], and [[Xojo]]. In dynamic languages like [[Python (programming language)|Python]], the concept of an extension method is unnecessary because nonclasses (excluding built-builtinin classes) can be extended without any special syntax (an approach known as "[[Monkey patch|monkey-patching]]", employed in libraries such as [[gevent]]).

In VB.NET and Oxygene, they are recognized by the presence of the "<code>extension</code>" keyword or attribute. In Xojo, the "<code>Extends</code>" keyword is used with global methods.
