* What is Lua? Lua is a simple, yet powerful, language for extending applications. Lua has been developed by TeCGraf, the Computer Graphics Technology Group of PUC-Rio, the Pontifical Catholic University of Rio de Janeiro, Brazil. Dozens of industrial products developed by TeCGraf use Lua. * Some features of Lua + a simple, pascal-like, syntax + powerful data description constructs (e.g., associative arrays) + user-controlled type constructors + fallbacks for extending the language in unconventional ways (e.g., inheritance, overloading) + garbage collection + Lua programs are compiled into bytecodes, which are then interpreted + portable, written in ANSI C (runs in Unix, DOS, Windows, Mac, Cray, ...) * Availability In Brazil: ftp://ftp.icad.puc-rio.br/pub/lua/lua-2.2.tar.gz In Canada: ftp://csg.uwaterloo.ca/pub/lhf/lua/lua-2.2.tar.gz Home page: http://www.inf.puc-rio.br/~roberto/lua.html * Legal matters Lua is freely available for both academic and commercial purposes. Lua is not in the public domain; TeCGraf keeps its copyright. See COPYRIGHT. * Changes since version 2.1 (current version is 2.2) + functions now may be declared with any "lvalue" as a name + garbage collection of functions + support for pipes * Changes since version 1.1 + object-oriented support + fallbacks + simplified syntax for tables + many internal improvements * Installing To make, simply type domake. If make succeeds, you get an interpreter in ./bin/lua. If make fails, please let me know. The libraries are in ./lib. The include files are in ./include. You don't need the other directories for development. There is a reference manual in ./doc, and tests and examples in ./test. This distribution is biased towards SunOS 4 with gcc but it is simple to change the Makefiles for other systems, if necessary. If you are running SunOs, type also "domake dynamic" to build shared libraries in ./lib. If your system does not have "popen", then change ./clients/lib/Makefile. * Contacting the authors Send your comments, bug reports and anything else to lhf@icad.puc-rio.br. Please send me email if you download Lua so that we can know how far it goes. -- Luiz Henrique de Figueiredo email: lhf@icad.puc-rio.br TeCGraf-Grupo de Tecnologia em Computacao Grafica, Dep.
