使用选项生成文档的多个版本

Question 1

您可以使用如下方法，我用它来创建 CV 文档的各种版本。

\documentclass{minimal}

\usepackage{ifthen}
\newboolean{somevariable}
\setboolean{somevariable}{false}

\begin{document}

\ifthenelse{\boolean{somevariable}}{Text if somevariable is true.}{Text if somevariable is false.}

\end{document}

\end{document}

Question 2

总是有docstrip，它允许您使用特殊注释（称为保护）区分一个代码与另一个代码，并且还具有两个代码所共有的代码。

在我看来，这种方法相对于条件语句的优势在于，添加更多语言相当简单，避免了嵌套条件语句的麻烦。

例如，您可以有一个源文件（我们将其命名为source.dtx，但任何其他名称都可以）：

\documentclass{book}
\begin{document}

%<english>\chapter{LITERATURE}
%<spanish>\chapter{LITERATURA}

%<*english>
\emph{The Tau Manifesto} is dedicated to one of the most important numbers in
mathematics, perhaps \emph{the} most important: the \emph{circle constant} relating
the circumference of a circle to its linear dimension. For millennia, the circle has
been considered the most perfect of shapes, and the circle constant captures the
geometry of the circle in a single number. Of course, the traditional choice for
the circle constant is $\pi$--but, as mathematician Bob Palais notes in his
delightful article ``$\pi$ Is Wrong!'', $\pi$ \emph{is wrong}. It's time to set
things right.
%</english>

%<*spanish>
\emph{El Manifiesto de Tau} está dedicado a uno de los números más importantes en
matemáticas, quizás \emph{el} más importante: la \emph{constante de círculo} que relaciona
la circunferencia de un círculo con su dimensión lineal. Durante milenios, el círculo ha
sido considerado la forma más perfecta, y la constante del círculo captura la
geometría del círculo en un solo número. Por supuesto, la elección tradicional para
la constante de círculo es $\pi$--pero, como señala el matemático Bob Palais en su
artículo encantador ``$\pi$ Is Wrong!'', $\Pi$ \emph{es incorrecto}. Es hora de arreglar las cosas.
%</spanish>

\end{document}

（样本文本取自这里并通过谷歌翻译为西班牙语）

那么您只需要一个所谓的“安装文件”：

\input docstrip % Loads the docstrip program
% Optional switches
\askforoverwritefalse % Allows it to overwrite older files without asking
\keepsilent % Reduces verbosity
\nopreamble % Removes preamble
\nopostamble % removes postamble
% Separating sources:
\generate{%
  %
  \file{english.tex}{%
    \from{source.dtx}{english}%
  }%
  %
  \file{spanish.tex}{%
    \from{source.dtx}{spanish}%
  }%
  %
}
% Exiting
\endbatchfile

它将根据中english.tex标记为的部分生成一个文件，并根据中标记为的部分生成另一个文件。中未标记的部分将进入两个输出文件。<english>source.dtxspanish.tex<spanish>source.dtxsource.dtx

要执行此操作，您只需在安装文件上运行 TeX：

> pdftex installation.ins

生成的结果english.tex如下：

\documentclass{book}
\begin{document}

\chapter{LITERATURE}
