Oxygene (programming language)

Oxygene (formerly known as Chrome) is a programming language developed by RemObjects Software for Microsoft's Common Language Infrastructure, the Java Platform and Cocoa. Oxygene is based on Delphi's Object Pascal, but also has influences from C#, Eiffel, Java, F# and other languages. Compared to the now deprecated Delphi.NET, Oxygene does not emphasize total backward compatibility, but is designed to be a "reinvention" of the language, be a good citizen on the managed development platforms, and leverage all the features and technologies provided by the .NET and Java runtimes. Oxygene is a commercial product and offers full integration into Microsoft's Visual Studio IDE on Windows, as well as its own IDE called Fire for use on macOS. Oxygene is one of six languages supported by the underlying Elements Compiler toolchain, next to C#, Swift, Java, Go and Mercury (based on Visual Basic.NET). From 2008 to 2012, RemObjects Software licensed its compiler and IDE technology to Embarcadero to be used in their Embarcadero Prism product. Starting in the Fall of 2011, Oxygene became available in two separate editions, with the second edition adding support for the Java and Android runtimes. Starting with the release of XE4, Embarcadero Prism is no longer part of the RAD Studio SKU. Numerous support and upgrade paths for Prism customers exist to migrate to Oxygene. As of 2016, there is only one edition of Oxygene, which allows development on Windows or macOS, and which can create executables for Windows, Linux, WebAssembly .NET, iOS, Android, Java and macOS. The Oxygene language has its origins in Object Pascal in general and Delphi in particular, but was designed to reflect the guidelines of .NET programming and to create fully CLR-compliant assemblies. Therefore, some minor language features known from Object Pascal / Delphi have been dropped or revised, while a slew of new and more modern features, such as Generics or Sequences and Queries have been added to the language.
