-
- try Lua (see below).
-
- * 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.
