全自動段落編號

tag-icon • tag-icon numbering paragraphs
全自動段落編號

我不確定我是否可以延長我的期限上一個問題所以我在這裡問。

我想要一種自動對段落進行編號的方法烏爾里克·費雪提供了一個極好的解決方案。我想擴展這個解決方案以減少手動幹預。所提供的方法明確要求暫時關閉段落編號。我確信可以修改\sectionand\subsection和\subsubsection命令，但我無法使其編譯，更不用說工作了。理想情況下，我想了解如何對這些命令以及其他我不會對段落編號（例如標題和腳註）執行此操作的命令。

MWE 1：手動介入（有效）

\documentclass[11pt]{article}

\usepackage{etoolbox}
\usepackage{lipsum}

\newbool{myparbool}
\booltrue{myparbool}
\newcounter{mypar}
\AddToHook{para/begin}
{\ifbool{myparbool}{\stepcounter{mypar}\llap{\P\themypar\quad}}{}}

\begin{document}

\boolfalse{myparbool}
\section{First}
\booltrue{myparbool}

All paragraphs should be numbered in the left margin but sections and subsections should not have paragraph numbers. This works but needs explicit manual control.

\lipsum[1]

\boolfalse{myparbool}

\subsection{Second}
\booltrue{myparbool}
\lipsum[2]
\boolfalse{myparbool}

\subsubsection{Third}
\booltrue{myparbool}
\lipsum[3]
\boolfalse{myparbool}

\section{Fourth}
\booltrue{myparbool}
\lipsum[4]
\end{document}

工作但需要手動幹預

MWE 2：無需手動幹預（需要修復）

\documentclass[11pt]{article}

\usepackage{etoolbox}
\usepackage{lipsum}

\newbool{myparbool}
\booltrue{myparbool}
\newcounter{mypar}
\AddToHook{para/begin}
{\ifbool{myparbool}{\stepcounter{mypar}\llap{\P\themypar\quad}}{}}

% New stuff that doesn't work: want to patch the \section, \subsection and \subsubsection commands

\usepackage{xpatch}
\newbool{parboolstatus}

\xpretocmd{\section}{%
  \bgroup%
  \ifbool{myparbool}%then
    {\setbool{parboolstatus}{true}}%else
    {\setbool{parboolstatus}{false}}
  \setbool{myparbool}{false}%
}{}{}
\xapptocmd{\section}{%
  \ifbool{parboolstatus}%then
    {\setbool{myparbool}{true}}%else
    {\setbool{myparbool}{false}}%
}{}{}
\apptocmd{\@xsect}{\egroup}{}{}

\begin{document}
\section{First}
All paragraphs should be numbered in the left margin but sections should not have paragraph numbers.

\lipsum[1]
\subsection{Second}
\lipsum[2]
\subsubsection{Third}
\lipsum[3]
\section{Fourth}
\lipsum[4]
\end{document}

導致編譯錯誤。

我已經嘗試過\addto，\addtocmd但這些也導致了編譯錯誤。最初我遇到了不同的錯誤，因為我沒有開始和結束一個小組。

我見過這個問題但我無法調整解決方案。我發現這但我也無法適應。

我還沒有找到這方面的初學者指南。我希望沒有這樣的話題，因為這不是真正適合初學者的話題。我也找不到鉤子清單。 @Ulrike 的原始答案使用，para/begin但我不知道是否有section/begin或等效的。

答案1

你很接近。試試這個程式碼。將使用編號和未編號的截面指令。

\documentclass[11pt]{article}

\usepackage{etoolbox}

\booltrue{myparbool}
\newcounter{mypar}

{\ifbool{myparbool}{\stepcounter{mypar}\llap{\P\themypar\quad}}{}}

答案2

Simon Dispa 的回答非常好！但不幸的是，當使用 fancyhdr 包時它會崩潰。

我將西蒙的工作與我在網上找到的其他一些東西結合起來（並且無法再找到...）。

\documentclass[]{article}

%%%% Packages %%%% 
\usepackage{lipsum}   % Package for lorum ipsum text.

\usepackage{fmtcount} % For converting counter to integer

\usepackage{fancyhdr} % For fancy headers/footers

\usepackage{etoolbox} % For more programming capabilities: pretocmd and apptocmd commands

%%%% Settings %%%%

\reversemarginpar     % Put the margin on the left

% Create a new counter, set it to 0
\newcounter{parcount}
\setcounter{parcount}{0}

% Create a new command "parnum".
% When invoked it adds to 'everypar' (i.e. every paragraph) the margin, after incrementing the counter by one.
\newcommand\parnum{
    \everypar{%
        \refstepcounter{parcount}%
        \marginpar[\hspace{1.5cm}\decimal{parcount}]{}%
}}

% Creates a command "noparnum" that de-activates the behaviour of \parnum
\newcommand\noparnum{\everypar{}}

%%% Reset paragraph counter when a new section is started.
\AddToHook{cmd/section/before}{\setcounter{parcount}{0}}


\makeatletter  % Hack to use @-commands in a non-style file.
% The pretocmd prepends the \noparnum to the ¿section? command so that sections don't have a paragraph number
% The apptocmd append the \parnum so that the paragraphs do have a paragraph number.
\pretocmd{\@ssect}{\noparnum\vspace{0.3cm}}{}{}
\apptocmd{\@ssect}{\parnum}{}{}
\pretocmd{\@sect}{\noparnum\vspace{0.3cm}}{}{}
\apptocmd{\@sect}{\parnum}{}{}
\makeatother % Hack to use @-commands in a non-style file.

\begin{document}

% Two settings for fancyhdr
\pagestyle{fancy}
\fancyhead[R]{{\textbf{Fancy header text}}}

    \section{First}
    All paragraphs should be numbered in the left margin but sections and 
    subsections should not have paragraph numbers. 
    
    \lipsum[1]
    
    \subsection{Susbsection}

    \lipsum[2]
    
    \subsubsection{subsubsection}

    \lipsum[3]
    
    \section*{Unnumbered section}

    \lipsum[4]
\end{document}
