[Tex/LaTex] Add a rule after chapter title using titlesec

rulessectioningtitlesec

I've been experimenting with chapter title formatting using titlesec but I can't seem to find the proper way to add a rule just below the chapter title. After reading the doc, I found that \titleline does that, but I'm not sure where in the \titleformat syntax to place it.

Here's one possible solution using the last optional argument for \titleformat to insert some vertical spacing and the rule:

\documentclass{book}
\usepackage{titlesec}

\titleformat{\chapter}[display]
{\normalfont\huge\bfseries}{\chaptertitlename\ \thechapter}{20pt}{\Huge}[\vspace{2ex}\titlerule]

\begin{document}

\chapter{Test Chapter}

\end{document}

Use the epigraph package.

Edit:

To remove unwanted space use \beforeepigraphskip=0pt. Here is a minimal:

\documentclass{book}  \usepackage[papersize={200pt,270pt}]{geometry}
\usepackage{epigraph}
 \usepackage{titlesec} \titleformat{\chapter}{\Large\bfseries}{Ch. \thechapter}{0em}{} \titlespacing*{\chapter}{0pt}{0pt}{0pt}
 \begin{document} 
\chapter{abc}\beforeepigraphskip=0pt
\epigraphhead[20]{\epigraph{Paragraph an more writing}{a}}

% \tt % \meaning\epigraph \newpage abc \end{document}

Uncomment the \meaning\epigraph to see the macro for \epigraph. This method of debugging is normally quicker than reading through manuals for obvious situations like this.

You can try

\documentclass{report}

\usepackage{mathptmx} % For the drop cap
\usepackage[showframe]{geometry} %Just to show the frame
\usepackage{lettrine} %For the drop cap
\usepackage{booktabs}

%% Choose one option: titlesec or sectsty
    \usepackage{titlesec}
    \titleformat{\chapter}[display]%
    {\normalfont\filcenter}%
    {\begin{tabular}{c}\scshape\Huge \chaptertitlename{} \thechapter{} \\[1ex]\bottomrule[2pt]\end{tabular}}%
    {15pt}%
    {\LARGE\bfseries}

    %\usepackage{sectsty}
    %\chapternumberfont{\centering\sc\Huge\underline}
    %\chaptertitlefont{\centering\LARGE}

\begin{document}

\chapter{Longer Introduction}
\label{chap:Intro}


\lettrine[lines=3]{S}{ustained} bipedal locomotion is one of the main characteristics that separates the human being from other primates.  For millennia this has marked a difference not only in the way \textit{Homo Sapiens} moves, but also has played a fundamental part in the evolution and subsequent development of human beings.
\end{document}

To change the distance of the line, change [1ex] to whatever you want. you can change the width of the line, I made it [2pt], which is probably too much. Notice that I \usepackage{booktabs}.
