titlesec 到 scrlayer-scrpage

Question

我正在尝试让我的文档不包含警告。其中之一是

Usage of package `titlesec' together(scrreprt) with a KOMA-Script class is not recommended.
Non standard sectioning command detected(titlesec) Using default spacing and no format.

我已经更改了布局，所以不再使用 titleformat。但是如果没有 \usepackage{titlesec}，代码仍然无法工作。我遗漏了什么？

\documentclass[11pt, a4paper]{scrreprt}

\usepackage{blindtext}
\usepackage{xcolor}
\usepackage{titlesec}
%\usepackage[headsepline, automark]{scrlayer-scrpage}

% \titleformat{\chapter}[display]     % {command}[shape]
%   {\usekomafont{chapter}\filcenter} % format
%   {                                 % label
%   {\fcolorbox{black}{shadecolor}{
%   {\huge\chaptertitlename\mbox{\hspace{1mm}}\thechapter}
%   }}}
%   {1pc}                             % sep (from chapternumber)
%   {\vspace{1pc}}                    % {before}[after] (before chaptertitle and after)

\KOMAoptions{chapterprefix}

\renewcommand{\chapterheadmidvskip}{%
    \vspace{12pt}
}
\setkomafont{chapter}{\Large\color{black}}
\renewcommand{\chapterlineswithprefixformat}[3]{%
    \parbox{\dimexpr\linewidth-2\fboxrule-2\fboxsep}{%
        #2 \vspace{.9pc}
        \hrule height 1pt \vspace{2pc}
        #3 \vspace{1.2pc}\hrule height 1pt%
    }
}
\renewcommand{\chapterheadmidvskip}{}
\renewcommand{\chapterformat}{%
    \mbox{\LARGE\MakeUppercase{Kapitel}\Huge~\thechapter\filright%
    }
}

\begin{document}
    \chapter{test}
    \blindtext
\end{document}

Answer 1

正如@campa 在评论中提到的那样，\filright它是由包定义的titlesec。

以下是一些额外的建议：不要重新定义\chapterheadmidvskip（这在您的 MWE 中已完成两次）。而是innerskip使用进行设置。在 的重新定义中\RedeclareSectionCommand添加。\raggedchapter\parbox\chapterlineswithprefixformat

\documentclass[ngerman]{scrreprt}% 11pt and paper=a4 are default

\usepackage{blindtext}
\usepackage{xcolor}
\usepackage{babel}
\usepackage[headsepline, automark]{scrlayer-scrpage}

\KOMAoptions{chapterprefix}

\RedeclareSectionCommand[
  innerskip=0pt,
  font=\Large\color{black},
  prefixfont=\LARGE
]{chapter}

\renewcommand{\chapterlineswithprefixformat}[3]{%
  \ifstr{#1}{chapter}{% <- change the layout for chapters
    \parbox{\dimexpr\linewidth-2\fboxrule-2\fboxsep}{%
        \raggedchapter% <- added (default meaning is \raggedright)
        #2 \vspace{.9pc}
        \hrule height 1pt \vspace{2pc}
        #3 \vspace{1.2pc}\hrule height 1pt%
    }%
  }{%
    #2#3% original definition for other levels with style=chapter
  }
}

\renewcommand{\chapterformat}{%
    \MakeUppercase{\chaptername}\Huge~\thechapter
}

\begin{document}
\chapter{test}
\blindtext
\Blinddocument
\end{document}
