我目前正在尝试设置一个文档模板，以便根据特定的“输入”自动创建不同的输出文件。
“输入”可以是变量或某种命令。
我想要实现的目标是
\documentclass{article}
\newcommand{\tool}{Photoshop}
\begin{document}
\section{Install Guide for the tool \tool}
\ldots
After installation, you can find the tool under ``C:\textbackslash Program
Files\textbackslash\tool''. \par\bigskip
Pseudocode starts here: \par\bigskip
if (\textbackslash tool == ``Photoshop''): \newline
The amazing thing about \textbackslash tool\ is: it is quite
expensive\ldots\newline
fi\par\bigskip
else if (\textbackslash tool == ``GIMP''): \newline
The amazing thing about \textbackslash tool is: it is freeware and
Open-Source as well!\newline
fi\par\bigskip
else: \newline
I don't know what tool you are talking about, please tell me more!
\end{document}
到目前为止，我只找到了将数字与\ifnum或 宏与进行比较的“if”示例\ifx。
但这似乎不适用于字符串。我知道includeonly和excludeonly包，但是一旦文档变大，它们就需要大量调整。
此外，从文档外部进行控制可能很困难includeonly/excludeonly（文档构建将通过 自动化ant）

您还可以使用\ifcsname：
\documentclass{article}
%\newcommand{\tool}{Photoshop}
%\newcommand{\tool}{GIMP}
%\newcommand{\tool}{Libre Office}
\newcommand{\tool}{Invisibility cloak}
%
\newcommand{\defineTool}[2]{\expandafter\newcommand\csname [#1]\endcsname{%
The amazing thing about #1 is: #2\newline}}
%
\newcommand{\toolInfo}[1]{%
\ifcsname [#1]\endcsname
\csname [#1]\endcsname
\else
``#1'', really? I don't know what tool you are talking about, please tell me more!
\fi
}
%
\defineTool{Photoshop}{it is quite expensive\ldots}
\defineTool{GIMP}{it is freeware and Open-Source as well!}
\defineTool{Libre Office}{%
it is the free power-packed open source personal productivity suite
for Windows, Macintosh and Linux.
}
\begin{document}
\section{Install Guide for the tool \tool}
\ldots
After installation, you can find the tool under ``C:\textbackslash Program
Files\textbackslash\tool''. \par\bigskip
\toolInfo{\tool}
\end{document}

当我需要完成类似的任务时，我使用了以下包：字符串。
