* 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 meaning of the language in unconventional ways;
+ Lua programs are compiled into bytecodes, which are then interpreted to
simulate a virtual machine;
+ portable, written in ANSI C.
* Availability
ftp://ftp.icad.puc-rio.br/pub/lua/lua-2.1.tar.gz
http://www.inf.puc-rio.br/projetos/roberto/lua.html
* Changes since version 1.1 (current version is 2.1)
+ 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.
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 in ./test.
This distribution is biased towards SunOS 4 with gcc but it is simple to
change the Makefiles for other systems.
If you are running SunOs, type also "domake dynamic" to build shared
libraries in ./lib.
* Legal matters
Lua is now freely available for both academic and commercial purposes.
Lua is not in the public domain; TeCGraf keeps its copyright.
* 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.
