LaTeX：每个字母后有空格

发布于 2024-09-27 23:26:14 字数 313 浏览 0 评论 0原文

我想定义一个 LaTeX 命令，在每个字母后插入一个空格。

那么，如果我添加

\addSpaces{someText}

结果应该是

s o m e T e x t

我怎样才能实现这一目标？

背景：我希望每个字母都带有下划线，但字母之间应该分隔线：

s o m e T e x t 
_ _ _ _ _ _ _ _

NOT:
s o m e T e x t

I want to define a LaTeX command that inserts a space after every letter.

So, If I add

\addSpaces{someText}

the result should be

s o m e T e x t

How could I achieve this?

Background: I want each letter to be underlined, but the line should be separated between the letters:

s o m e T e x t 
_ _ _ _ _ _ _ _

NOT:
s o m e T e x t

您可以使用 soul 包进行下划线。对于单个单词，您可以使用我在下面编写的 \addspaces 宏。（宏将吞掉单词之间的空格。一个简单的解决方法是使用 \quad 来增加单词之间的空格。）

\documentclass{article}

\usepackage{soul}% provides underlining

\makeatletter% since we're using a macro containing @
\newcommand{\addspaces}[1]{%
  \@tfor\letter:=#1\do{%
    \ul{\letter}\space
  }%
}
\makeatother% resets @ to its original meaning

\begin{document}

% Works fine for single words
\addspaces{Spaces}

% Note that spaces in between words aren't preserved -- use \quad to add extra space.
\addspaces{Spaced\quad and\quad underlined.}

\end{document}

You can use the soul package for underlining. For single words, you can use the \addspaces macro I wrote below. (The macro will swallow the space between words. A simple workaround is to use \quad to increase the space between the words.)

\documentclass{article}

\usepackage{soul}% provides underlining

\makeatletter% since we're using a macro containing @
\newcommand{\addspaces}[1]{%
  \@tfor\letter:=#1\do{%
    \ul{\letter}\space
  }%
}
\makeatother% resets @ to its original meaning

\begin{document}

% Works fine for single words
\addspaces{Spaces}

% Note that spaces in between words aren't preserved -- use \quad to add extra space.
\addspaces{Spaced\quad and\quad underlined.}

\end{document}

对于文本的编程操作，我发现使用 perltex 定义 perl 函数来执行代码然后编译文档要容易得多。请参阅此处的 CTAN。

这是一个快速而肮脏的过程。

\documentclass{article}
\usepackage{perltex}

\perlnewcommand{\ulspace}[1]{
$input = shift;
$input =~ s/(\w)/\\underline\{\1\} /g;
return $input;
}

\begin{document}

\ulspace{Hello World}

\end{document}

编译：

perltex --latex=pdflatex myfile.tex

For programmatic manipulation of text I find it much easier to use perltex to define a perl function to do the code and then compile the document. See CTAN here.

Here is a quick and dirty.

\documentclass{article}
\usepackage{perltex}

\perlnewcommand{\ulspace}[1]{
$input = shift;
$input =~ s/(\w)/\\underline\{\1\} /g;
return $input;
}

\begin{document}

\ulspace{Hello World}

\end{document}

Compile with:
