声明首字母缩略词和缩写以自动更正句号后的空格？

Question

如果我理解正确的话，(La)TeX 认为小写字母后的句号结束一个句子，而大写字母后的句号则不结束。不幸的是，我的文档通常包含大量首字母缩略词和缩写。除非我记得使用\@，否则句号后的空格是错误的：

\documentclass[convert={density=150},varwidth]{standalone}
\begin{document}
\noindent
\makebox[0.7in][l]{Incorrect:}%
Your computer needs more RAM.  I can give you some.\\
\makebox[0.7in][l]{Correct:}%
Your computer needs more RAM\@.  I can give you some.\\
\makebox[0.7in][l]{Incorrect:}%
Colors (red, blue, etc.) are nice.\\
\makebox[0.7in][l]{Correct:}%
Colors (red, blue, etc.\@) are nice.
\end{document}

是否可以将某些字符串声明为首字母缩略词或缩写来推翻这一假设？如果是这样，这将减少我的文档中的间距错误数量。

例如：

\documentclass[convert={density=150},varwidth]{standalone}
\usepackage{magicalacronymhelper}
\declareacronym{RAM}
\declareabbr{etc}
\begin{document}
\noindent
\makebox[0.7in][l]{Correct:}%
Your computer needs more RAM.  I can give you some.\\
\makebox[0.7in][l]{Correct:}%
Your computer needs more RAM\@.  I can give you some.\\
\makebox[0.7in][l]{Correct:}%
Colors (red, blue, etc.) are nice.\\
\makebox[0.7in][l]{Correct:}%
Colors (red, blue, etc.\@) are nice.
\end{document}

Answer 1

没有办法自动执行此操作，除非您愿意使用 XeLaTeX 和不受支持的包xesearch。

您可以做的最好的事情是定义宏\acro和\abbr：

\newcommand{\acro}[1]{#1\@}
\makeatletter
\newcommand{\abbr}{\@ifstar\@firstofone\@abbr}
\newcommand{\@abbr}[1]{#1.\@}
\makeatother

完整示例：

\documentclass{article}
\newcommand{\acro}[1]{#1\@}
\makeatletter
\newcommand{\abbr}{\@ifstar\@firstofone\@abbr}
\newcommand{\@abbr}[1]{#1.\@}
\makeatother

\begin{document}
\noindent
Your computer needs more \acro{RAM}.  I can give you some.\\
Your computer needs more RAM\@.  I can give you some.\\[3pt]
Colors (red, blue, \abbr{etc}) are nice.\\
Colors (red, blue, etc.\@) are nice.\\[3pt]
I like citrus flavors: orange, lemon, lime, \abbr*{etc}. They are tasty\\
I like citrus flavors: orange, lemon, lime, etc\@. They are tasty
\end{document}
