Cobra is a general-purpose, object-oriented programming language.[1] Cobra is designed by Charles Esterbrook, and runs on the Microsoft .NET and Mono platforms.[2] It is strongly influenced by Python, C#, Eiffel, Objective-C, and other programming languages.[3] It supports both static and dynamic typing.[4][5] It has first class support for unit tests and contracts.[4] It has lambda expressions, closures, list comprehensions, and generators.[6] Cobra provides both rapid development and performance in the same language.[7]
Cobra is an open-source project; it was released under the MIT License on February 29, 2008.[8]
Updates are posted to the Cobra news forum with progress on features, fixes, documentation and related projects since the last update.[9]
