Newspeak is aprogramming language andplatform in the tradition ofSmalltalk andSelf being developed by a team led byGilad Bracha.^[1] The platform includes anintegrated development environment (IDE), agraphical user interface (GUI)library, and standard libraries.^[2] Starting in 2006,Cadence Design Systems funded its development and employed the main contributors, but ended funding in January 2009.^[3]

Newspeak is aclass-based andmessage-based language. Classes may be nested, as inBETA. This is one of the key differences between Newspeak and Smalltalk.

Newspeak is distinguished by its unusual approach to modularity.^[4] The language has no global namespace. Top level classes act as module declarations. Modularity in Newspeak is based exclusively on class nesting.^[1] Module declarations are first class values (i.e., they may be stored in variables, passed as parameters, returned from methods, etc.) and are stateless.

By design the newspeak lacks undeclared access to a global scope and therefore enforcesdependency injection. As consequence it requires all class dependencies (instance variables referred as by "slots") to be explicitly referenced. This makes every class in Newspeakvirtual.^[1] All names of dependencies in Newspeak arelate-bound (dynamically bound), and are interpreted asmessage sends, as in Self.

A notable feature of newspeak is its impossibility to directly access instance variables. It's done via automatically generated getters orsetters.^[1]: 3

While developed at Cadence Newspeak was used to write its own IDE (compiler, debugger, class browsers, object inspectors, unit testing framework, a mirror based reflection API etc.), a portable GUI tool kit, an object serializer/deserializer, a parser combinator library, a regular expression package, core libraries for collections, streams, strings and files, parts offoreign function interface and CAD application code.^[5] The Newspeak platform as a whole took approximately 8 person years of work.^[1]: 17

The nameNewspeak is inspired by theNewspeak language appearing inGeorge Orwell's dystopian novelNineteen Eighty-Four. The heading on the programming language's website says "It'sdoubleplusgood". The motive for the name is that Orwell's Newspeak language grew smaller with each revision;^[6] Bracha views this as a desirable goal for a programming language.

The language icon is supposed to beBig Brother's eye, as seen in page 3 of the documentation.

It should not be confused with the safety critical programming language of the same name designed by Ian Currie ofRSRE in 1984, for use with theVIPER microprocessor. Its principal characteristic was that its compiler would ensure all potential exceptional behaviour is explicitly handled by the program.^[7][8]

Primordial Soup is avirtual machine (VM) that runs Newspeak binary snapshopts of serialized Newspeak files.^[9] Internal Object Representation was inspired by theDart VM and provides basic VM primitives for the language.^[9] It can be compiled bySCons on various platforms.
