Survey of selected Delegation-based Programming Languages
Delegation-based programming languages, also known as Prototype-based programming languages, represents a style of object-oriented programming in which classes are not present, and behavior reuse (known as inheritance in class-based languages) is performed via a process of cloning existing objects that serve as prototypes. This model can also be known as class-less, prototype-oriented or instance-based programming. Delegation is the language feature that supports prototype-based programming.
The original, and most canonical, example of a prototype-based language is the programming language Self developed by David Ungar and Randall Smith. Since the late 1990s, the classless programming style has grown increasingly popular, and has been adopted for the languages Javascript, ActionScript, Cecil, NewtonScript, Io, Moo, REBOL, Lisaac, Lua and several others.[1] This topic will briefly review features of three Delegation-based programming languages: Lua, Io, and Actionscript.
Lua
= History of Lua
Lua was created in 1993 by Roberto Ierusalimschy, Luiz Henrique de Figueiredo, and Waldemar Celes, members of the Computer Graphics Technology Group (Tecgraf) at the Pontifical Catholic University of Rio de Janeiro, in Brazil. Lua is designed, implemented, and maintained by a team at PUC-Rio, the Pontifical Catholic University of Rio de Janeiro in Brazil. Lua was born and raised in Tecgraf, the Computer Graphics Technology Group of PUC-Rio, and is now housed at Lablua. Both Tecgraf and Lablua are laboratories of the Department of Computer Science of PUC-Rio.
