I plan (or rather, hope) to eventually publish on this page some
of
the tools I designed for my own use over many years, even if presently
it looks rather sparsely populated (I'd have to find time to clean them
up, add a suitable license, and so on).
Lua is a powerful, flexible and
elegant
dynamic language, designed and written by Waldemar Celes, Roberto
Ierusalimschy and Luiz Henrique de Figueiredo at TeCGraf, PUC-Rio in
Brazil.
gpeddler 2 is a primitive TSP evolutionary solver written to evaluate wxLua,
a Lua interface to the wxWindows portable interface library. It
contains examples of:
- Coroutines for cooperative multitasking.
- Buffered drawing for flicker-free animation.
- A simple approach to object-oriented Lua programming
(without metamethods).
- Using closures in callbacks.
The HTML documentation, detailing the above points, can also be
read from within the program itself, thanks to the HTML rendering
capabilities included in wxWindows.
gpeddler 2 works under the systems supported by wxLua (currently Windows
and Linux).
Requirements: wxLua 2.1 or
later (Lua and wxWindows are included in the wxLua executable).
Here is a screenshot of gpeddler 2 running under GTK (Linux RedHat
8.0a):
Glua is a set of macros and functions designed to help a C programmer
writing Lua-C interface functions by hand, while retaining
error
control and high efficiency. Its name means "Lua-C glue".
(actually, I designed it because I didn't know of the Lua auxiliary
library...)
Requirements: Lua 4.0 (basic
functionality with Lua 5.0 can be obtained with a few changes I did for
my own use, but I don't like the idea of releasing a version with
limited functionality; email me if you are interested).
Bare-bones working examples are included.
GluaX
: Asko Kauppi designed GluaX, a powerful tool derived
from Glua that adds many capabilities to Glua (including Lua 5.0
compatibility) and also includes provisions for
runtime loadable modules; the latest version of Glua-X can be found at this
page.
Be patient. Be very patient. I have more software than spare time (and
willingness to clean it up for publication...).
