Lua is dynamically typed, interpreted from bytecodes, and has + automatic memory management, making it ideal for configuration, scripting, + and rapid prototyping. + + 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. -* Some features of Lua - + simple syntax (Pascal-like); - + powerful data description constructs (e.g., associative arrays); - + user-controlled type constructors; - + extensible semantics with tag methods; - + garbage collection; - + Lua programs are compiled into bytecodes, which are then interpreted; - + truly portable, written in ANSI C. + Lua has been awarded the first prize (technological category) in the Second + Compaq Award for Research and Development in Computer Science. This award + is a joint venture of Compaq Computer in Brazil, the Brazilian Ministry of + Science and Technology, and the Brazilian Academy of Sciences. * Availability - The latest version of Lua is always available at the following locations: - In Brazil: ftp://ftp.icad.puc-rio.br/pub/lua/lua.tar.gz + Lua is freely available for both academic and commercial purposes and + can be downloaded from the sites below.
