Overview

CGILua is a tool for creating dynamic Web pages and manipulating input data from Web forms. CGILua allows the separation of logic and data handling from the generation of pages, making it ease to develop web applications with Lua. One of advantages of CGILua is its abstraction of the underlying Web server. You can develop a CGILua application for one Web server and run it on any other Web server that supports CGILua.

CGILua is free software and uses the same license as Lua 5.0.

Status

Current version is 5.0.

Download

CGILua can be downloaded in source code from its LuaForge page

CGILua 5.0

CGILua 5.0 was completely redesigned by Roberto Ierusalimschy, André Carregal and Tomás Guisasola as part of the Kepler Project. The implementation is compatible with Lua 5.0 and was coded by Tomás Guisasola with invaluable contributions by Ana Lúcia de Moura, Fábio Mascarenhas and Danilo Tuler. CGILua 5.0 development was sponsored by Fábrica Digital, FINEP and CNPq.

CGILua 4.0

Ana Lúcia de Moura adapted CGILua 3.2 to Lua 4.0, reimplemented some code and added a few improvements but this version was not officially distributed.

CGILua 3.x

CGILua was born as the evolution of an early system developed by Renato Ferreira Borges and André Clínio at TeCGraf. At the time (circa 1995) there were no CGI tools available and everything was done with shell scripts!
However, the main contribution to CGILua 3 was done by Anna Hester, who consolidated the whole tool and developed a consistent distribution with versions 3.1 and 3.2 (the number was an effort to follow Lua version numbers). This version was widely used on a great variety of systems.
