{The \texttt{luatruthtable} package in \LaTeX}
{Chetan Shirore, Ajit Kumar}
{This paper describes the development and usage of the \texttt{luatruthtable}
package in \LaTeX. It is developed to generate truth tables of boolean
values in a \LaTeX\ document. The package provides an easy way of generating
truth tables in \LaTeX. There is no need of special environment in \LaTeX\
in the package for the generation of truth tables. It is written in Lua and
\TeX\ file is to be compiled with \LuaLaTeX\ engine.

The Lua programming language is a scripting language which can be
embedded across platforms. With \LuaTeX\ and the \texttt{luacode}
package, it is possible to use Lua in \LaTeX. \AllTeX\ have some scope
for programming, but with the internals of \TeX\ there are several
limitations especially for performing calculations. Packages like
\texttt{pgf} and \texttt{{xparse} in \LaTeX\ provide some programming
capabilities inside \LaTeX\ documents, but such packages are not meant
to provide the complete programming structure that general programming
languages, like Lua, provide.

The generation of truth tables with these packages in \LaTeX\ became
complex, and probably without using Lua it can't be done in an easier
way in \LaTeX. The programming capabilities of Lua are effectively used
in the development of \texttt{{luatruthtable}package. The
\texttt{xkeyval} package is used in its development, in addition to the
\texttt{luacode} package. The time needed for generation of truth tables
using the package and compilation of a \TeX\ document with \LuaTeX\ is
not an issue.}
