柯马体信件窗口中的两行反向地址

Question

scrlttr2似乎不喜欢长度超过一行的“反向地址”。默认布局的两行反向地址在“地址窗口”顶部突出，并且基线距离非常大。

我想找到一个配置，涵盖由 和 构建的单行和双行反向地址fromname，fromaddress因为布局是在 LCO 文件中定义的，该文件由不同的人使用。为了保持处理简单，定义单独的较短反向地址也不是一种选择。处理双行反向地址的一种方法似乎是。这种方法有点管用（请参阅下面的 MWE）。但我无法使用和parbox获得良好的单词间距和正确的连字符。parboxraggedright

因此，我正在寻找一个具有正确连字符、单词间距以及可能的话左对齐的解决方案。

我尽力而为的 MWE：

\documentclass[backaddress=plain]{scrlttr2}

\usepackage[main=ngerman]{babel}
\usepackage{blindtext}

% visualize border of address window
\LoadLetterOption{visualize}
\showfields{address}
\setkomafont{field}{\color{blue}}

\setkomavar{fromname}{Max Mustermann}
\setkomavar{fromaddress}{Mittelhochdeutsche Allgemeine Versuchsanstalt\\Musterstr. 12\\34567 Musterstadt}


% construct a new backaddress
\makeatletter
\@setplength{backaddrheight}{18pt}

\setkomavar{backaddress}{\parbox[c]{\useplength{toaddrwidth}}{%
{%\raggedright%     <- (1) has no effect
\def\\{\usekomavar{backaddressseparator}\@ogobble}%
%\raggedright%      <- (2) breaks replacment of \\ with separator
\usekomavar{fromname}\usekomavar{backaddressseparator}\usekomavar{fromaddress}}%
\raggedright%       <- (3) prevents hyphenation but is left aligned 
}}
\makeatother


\begin{document}
\begin{letter}{Dr. Moritz Busch\\Georgengarten\\30167 Hannover}

Answer 1

要获得正确的连字符和左对齐文本，只需使用包ragged2e和命令\RaggedRight（请注意两个大写的 R）。

使用以下 MWE

\documentclass[backaddress=plain]{scrlttr2}

\usepackage[main=ngerman]{babel}
\usepackage{blindtext}
\usepackage{ragged2e} % <===============================================

% visualize border of address window
\LoadLetterOption{visualize}
\showfields{address}
\setkomafont{field}{\color{blue}}

\setkomavar{fromname}{Max Mustermann}
\setkomavar{fromaddress}{Mittelhochdeutsche Allgemeine Versuchsanstalt\\Musterstr. 12\\34567 Musterstadt}


% construct a new backaddress
\makeatletter
\@setplength{backaddrheight}{18pt}

\setkomavar{backaddress}{\parbox[c]{\useplength{toaddrwidth}}{%
{%\raggedright%     <- (1) has no effect
\def\\{\usekomavar{backaddressseparator}\@ogobble}%
%\raggedright%      <- (2) breaks replacment of \\ with separator
\usekomavar{fromname}\usekomavar{backaddressseparator}\usekomavar{fromaddress}}%
\RaggedRight%       <- (3) prevents hyphenation but is left aligned <================
}}
\makeatother


\begin{document}
\begin{letter}{Dr. Moritz Busch\\Georgengarten\\30167 Hannover}
\opening{Mein lieber Freund,}
\blindtext[1]
\closing{Bis bald,}
\end{letter}
\end{document} 

你得到了想要的结果：

Answer 2

我将重新定义backaddressseparator以允许在之后休息,：

\setkomavar{backaddressseparator}{,\ }

然后你可以使用

\documentclass[backaddress=plain]{scrlttr2}
\usepackage[main=ngerman]{babel}
\usepackage{blindtext}

% visualize border of address window
\LoadLetterOption{visualize}
\showfields{address}
\setkomafont{field}{\color{blue}}

\setkomavar{fromname}{Max Mustermann}
\setkomavar{fromaddress}{Mittelhochdeutsche Allgemeine Versuchsanstalt\\Musterstr. 12\\34567 Musterstadt}

% construct a new backaddress
\setplength{backaddrheight}{18pt}% 
\setkomavar{backaddressseparator}{,\ }
\setkomavar{backaddress}{%
  {\usekomavar{fromname}\usekomavar{backaddressseparator}\usekomavar{fromaddress}\par}%
}

\begin{document}
\begin{letter}{Dr. Moritz Busch\\Georgengarten\\30167 Hannover}
\opening{Mein lieber Freund,}
\blindtext[1]
\closing{Bis bald,}
\end{letter}
\end{document}

或者

\documentclass[backaddress=plain]{scrlttr2}
\usepackage[main=ngerman]{babel}
\usepackage{blindtext}

% visualize border of address window
\LoadLetterOption{visualize}
\showfields{address}
\setkomafont{field}{\color{blue}}

\setkomavar{fromname}{Max Mustermann}
\setkomavar{fromaddress}{Mittelhochdeutsche Allgemeine Versuchsanstalt\\Musterstr. 12\\34567 Musterstadt}

% construct a new backaddress
\setplength{backaddrheight}{18pt}
\setkomavar{backaddressseparator}{,\ }
\makeatletter
\setkomavar{backaddress}{\parbox[c]{\useplength{toaddrwidth}}{%
  \def\\{\usekomavar{backaddressseparator}\@ogobble}%
  \usekomavar{fromname}\usekomavar{backaddressseparator}\usekomavar{fromaddress}}%
}
\makeatother

\begin{document}
\begin{letter}{Dr. Moritz Busch\\Georgengarten\\30167 Hannover}
\opening{Mein lieber Freund,}
\blindtext[1]
\closing{Bis bald,}
\end{letter}
\end{document}

但我会定义一个新变量shortfromaddress：

\documentclass[backaddress=plain]{scrlttr2}
%\providecommand*{\Ifkomavarempty}{\ifkomavarempty}% needed up to and including KOMA-Script version 3.27, see https://komascript.de/faq_deprecatedif
\usepackage[main=ngerman]{babel}
\usepackage{blindtext}

% visualize border of address window
\LoadLetterOption{visualize}
\showfields{address}
\setkomafont{field}{\color{blue}}

\setkomavar{fromname}{Max Mustermann}
\setkomavar{fromaddress}{Mittelhochdeutsche Allgemeine Versuchsanstalt\\Musterstr. 12\\34567 Musterstadt}

% construct a new backaddress
\newkomavar{shortfromaddress}
\setkomavar{backaddress}{%
  \usekomavar{fromname}\usekomavar{backaddressseparator}
  \Ifkomavarempty{shortfromaddress}%
    {\usekomavar{fromaddress}}
    {\usekomavar{shortfromaddress}}%
}


\setkomavar{shortfromaddress}{MAV\\Musterstr. 12\\34567 Musterstadt}

\begin{document}
\begin{letter}{Dr. Moritz Busch\\Georgengarten\\30167 Hannover}
\opening{Mein lieber Freund,}
\blindtext[1]
\closing{Bis bald,}
