定义缩写命令

我想要发出一个命令，例如：

\newcommand{abbre}{...}

\def\abbre{Modular Response}

并\abbre应显示MR.

谢谢

答案1

根据我的回答修改仅排版一组中的第一个字母至：1）删除字母之间的空格；2）仅显示短语的大写单词的字母；3）创建缩写名称的宏以调用原始短语（请参阅\MRT我的 MWE 中的示例）。

这样您就可以双向工作。例如，我可以说Modular Response of Tissue"并将其缩写为\abbre{Modular Response of Tissue}。MRT另一方面，在进行过一次缩写之后，我可以使用 来制定我的文档，MRT并\MRT得到短语Modular Response of Tissue。

可以使用 重新访问最近定义的缩写词\theabbre。如果您不希望在调用 时打印出缩写词，请将“quiet”的\abbre{}可选参数传递给它，如 中所示。如果它是最近定义的缩写词，您可以稍后使用 访问它。[q]\abbre[q]{Modular Response of Tissue}\theabbre

缩写的长度不受限制。

\documentclass[]{article}
\newcommand\abbre[2][v]{\def\theabbre{}%
  \expandafter\justfirstCAPS#2 \relax\relax\if q#1\else\theabbre\fi%
  \expandafter\def\csname\theabbre\endcsname{#2}}

  \protected@edef\theabbre{\theabbre#1}\fi\fi%
  \if\relax#3\else\justfirstCAPS#3\relax\fi}

This prints \abbre{Modular Response of Tissue} as the abbreviation to Modular 
  Response of Tissue, which can thereafter be recalled with the
shorthand \verb|\MRT| as \MRT.  The most recently defined acronym is \theabbre.

Abbreviations are not limited to two, three, or even nine characters:

One of the longest internet acronyms, according to 
\texttt{www.urbandictionary.com}, is\\
\abbre{\x},\\ which stands for ``\x''.

\documentclass{article}

\makeatletter
\newcommand*\firstL[1]{\@car #1\@empty\@nil}
\newcommand*\firstLetter[1]{\expandafter\@firstLetter#1 \@nil}
\def\@firstLetter#1 #2\@nil{%
  \firstL{#1}\ifx\\#2\\\else\@ReturnAfterFi{\@firstLetter#2\@nil}\fi}
\long\def\@ReturnAfterFi#1\fi{\fi#1}
\makeatother
\newcommand\abbre{Modular Response}
\begin{document}

\abbre~is the long version and \firstLetter{\abbre} the
short one. And \firstLetter{Modular Response} also. And
\firstLetter{This Is Also Returned With The first Letter}

我可以提供一个更短的宏（只有两行 \abbre 宏）：

\def\abbre#1{\expandafter\abbreA#1 \relax/ }
\def\abbreA#1#2 {\ifx#1\relax \else\ifnum\uccode`#1=`#1#1\fi\expandafter\abbreA\fi}

\def\macro{Modular and Response}

\abbre{Something Text is Here} or \abbre\macro.

结果是：STH 或 MR。该宏\abbre是可扩展的，因此可以定义为：

\edef\abbremacro{\abbre\marco} % Now the meaning of \abbremacro is MR.
