Put the source file `secnum.dtx` in a empty folder and go to there. 1. Run the following to create the package file `secnum.sty` (as well as this file `README.md`) XeTeX secnum.dtx 2. Move the following file into proper directories searched by TeX. The recommended directory is tex/latex/secnum 3. To produce the documentation run the following XeLaTeX secnum.dtx 4. The recommended directory for the documentation is doc/latex/secnum ## Download One can also download the generated files from the [github release](https://github.com/GauSyu/secnum/releases). % %<*internal> \fi \begingroup \def\nameoflatexe{LaTeX2e} \expandafter\endgroup\ifx\nameoflatexe\fmtname\else \csname fi\endcsname % %<*install> \input docstrip.tex \preamble Copyright (C) 2019-- Gau, Syu ( GauSyu@Gmail.com ) ---------------------------------------------------------------------- This work may be distributed and/or modified under the conditions of the LaTeX Project Public License, either version 1.3c of this license or (at your option) any later version.

\tableofcontents % \begin{documentation} % \section{Usage} % Before using the macro, load the package in preamble. % \begin{verbatim} % \usepackage{secnum} % \end{verbatim} % Then, one can format the section numbering by using the % marco \cs{setsecnum} in preamble. % \begin{function}{\setsecnum} % \begin{syntax} % \cs{setsecnum}\marg{num format} % \end{syntax} % A typical \meta{num format} is like this: % \begin{center} % \verb|1.1.1| % \end{center} % It consists of some syntax abbrs of numbering formats, % reffering the follows, % \begin{center} % \begin{tabular}{ccccc} % \toprule % A & a & I & i & 1 \\ % \midrule % \cs{Alph} & \cs{alph} & \cs{Roman} & \cs{roman} & \cs{arabic} \\ % \bottomrule % \end{tabular} % \end{center} % and some separators, which can be any character except % the abbrs and special characters such as barces ``\verb|{}|'', % comma ``\verb|,|'', space ``\verb*| |'', etc. % \end{function} % % \section{Process} % The process of the macro \cs{setsecnum} can be % explained as follows. % \begin{enumerate}[label=Step \arabic*.] % \item The main function eats the input, saying \opt{I.1.a}, % and stores it in a token list. % \item Replace abbrs by macros. % In our example, it results % ``\cs{Roman}\opt{.}\cs{arabic}\opt{.}\cs{alph}'' % \item Split this token list into a sequence by macros. % In our example, it results ``\cs{Roman}'', % ``\opt{.}\cs{arabic}'' and ``\opt{.}\cs{alph}''. % \item Store those codes in indivial containers. % \item Use them to renew \cs{thesection}, \cs{thesubsection}, % \cs{thesubsubsection} etc. % provided there is no \cs{chapter}. % \end{enumerate} % % \end{documentation} % % \StopEventually{} % % \begin{implementation} % \section{Implementation} % The following is the implementation. % Users can ignore. %
