This package -% adapts the way the files are searched in order to accommodate the TDS as -% well as usual Lua naming conventions. -% -% For higher-level functions related to Lua modules, see -% \href{file:luatexbase-modutils.pdf}{\pk{luatexbase-modutils}}, which also -% loads the present package. -% \end{abstract} -% -% \section{Documentation} -% -% Starting with \luatex 0.45, |require()| uses Kpathsea for file searching -% when the library is initialised (which is always the case in \tex mode, -% unless explicitly disabled by the user). However, it did not respect the -% Lua convention that |require("foo.bar")| should look for |foo/bar.lua| until -% version 0.60. \luatex 0.74 ships with Lua 5.2 that has a different loading -% system. -% -% The aim of this package is to have a coherent behaviour between versions of -% LuaTeX, and to get the loaded file's name printed in the output (\LaTeX -% style). The first versions did ensure backward compatibilty to \luatex 0.25 -% but as \luatex development is quite fast, this version supports only \luatex -% 0.45 and higher. -% -% More precisely, when asked for |foo.bar| (or |foo.bar.lua|), it first looks -% for file |foo/bar| using Kpathsea with the format |lua|, and then for -% |foo.bar|, removing the possible extension. -% -% \section{Implementation} -% -% \subsection{\tex package} -% -% \begin{macrocode} -%<*texpackage> -% \end{macrocode} -% -% \subsubsection{Preliminaries} -% -% Catcode defenses and reload protection. -% -% \begin{macrocode} -\begingroup\catcode61\catcode48\catcode32=10\relax% = and space - \catcode123 1 % { - \catcode125 2 % } - \catcode 35 6 % # - \toks0\expandafter{\expandafter\endlinechar\the\endlinechar}% - \edef\x{\endlinechar13}% - \def\y#1 #2 {% - \toks0\expandafter{\the\toks0 \catcode#1 \the\catcode#1}% - \edef\x{\x \catcode#1 #2}}% - \y 13 5 % carriage return - \y 61 12 % = - \y 32 10 % space - \y 123 1 % { - \y 125 2 % } - \y 35 6 % # - \y 64 11 % @ (letter) - \y 10 12 % new line ^^J - \y 34 12 % " - \y 39 12 % ' - \y 40 12 % ( - \y 41 12 % ) - \y 44 12 % , - \y 45 12 % - - \y 46 12 % . - \y 47 12 % / - \y 58 12 % : - \y 91 12 % [ - \y 93 12 % ] - \y 94 7 % ^ - \y 95 8 % _ - \y 96 12 % ` - \toks0\expandafter{\the\toks0 \relax\noexpand\endinput}% - \edef\y#1{\noexpand\expandafter\endgroup% - \noexpand\ifx#1\relax \edef#1{\the\toks0}\x\relax% - \noexpand\else \noexpand\expandafter\noexpand\endinput% - \noexpand\fi}% -\expandafter\y\csname luatexbase@loader@sty@endinput\endcsname% -% \end{macrocode} -% -% Package declaration. -% -% \begin{macrocode} -\begingroup - \expandafter\ifx\csname ProvidesPackage\endcsname\relax - \def\x#1[#2]{\immediate\write16{Package: #1 #2}} - \else - \let\x\ProvidesPackage - \fi -\expandafter\endgroup -\x{luatexbase-loader}[2013/05/11 v0.6 Lua module loader for LuaTeX] -% \end{macrocode} -% -% Make sure \luatex is used. -% -% \begin{macrocode} -\begingroup\expandafter\expandafter\expandafter\endgroup -\expandafter\ifx\csname RequirePackage\endcsname\relax - \input ifluatex.sty -\else - \RequirePackage{ifluatex} -\fi -\ifluatex\else - \begingroup - \expandafter\ifx\csname PackageError\endcsname\relax - \def\x#1#2#3{\begingroup \newlinechar10 - \errhelp{#3}\errmessage{Package #1 error: #2}\endgroup} - \else - \let\x\PackageError - \fi - \expandafter\endgroup - \x{luatexbase-loader}{LuaTeX is required for this package.
