Lua +combines simple procedural syntax (similar to Pascal) with powerful data +description constructs based on associative arrays and extensible semantics. +Lua is dynamically typed, interpreted from bytecodes, and has automatic memory +management with garbage collection, making it ideal for configuration, +scripting, and rapid prototyping. + +A fundamental concept in the design of Lua is to provide meta-mechanisms for +implementing features, instead of providing a host of features directly in +the language. For example, although Lua is not a pure object-oriented +language, it does provide meta-mechanisms for implementing classes and +inheritance. Lua's meta-mechanisms bring an economy of concepts and keep the +language small, while allowing the semantics to be extended in unconventional +ways. Extensible semantics is a distinguishing feature of Lua. + +Lua is implemented as a small library of C functions, written in ANSI C, and +compiles unmodified in all known platforms. The implementation goals are +simplicity, efficiency, portability, and low embedding cost. + +WWW: http://www.tecgraf.puc-rio.br/lua/ |
