[Tex/LaTex] titlesec and \section* in \titleformat

sectioningstarred-versiontitlesec

I use \titleformat (titlesec package) to make some fancy headings in my documents. But I did not find a way to know, in the \titleformat specifications, if the section is made with a \section or a \section*.

Is there a way to detect that and make some test on it ?

What I want (a minimal example):

\usepackage[explicit]{titlesec}
\titleformat{\section}[block]{first}{label}{0pt}{\ifsectionstar{#1}{\bf #1}}[trailer]

You can define the titleformat for starred versions with the numberless key, i.e, like

\titleformat{\section}[block]           {first}{label}{0pt}{\textbf{#1}}[trailer] % all versions
\titleformat{\section}[block,numberless]{first}{label}{0pt}{#1}[trailer] % starred version

All the sectioning commands are in class (book, article report etc). Search in your distribution and look for book.cls.

They are quite lengthy and they are not in one place. For example all the "name" commands can be found towards the end of the class in one place.

Here is a minimal as to how to change some of the parameters.

\documentclass[oneside]{book}
\makeatletter
\renewcommand\chaptername{chapteris}
\renewcommand \thechapter {\@Roman\c@chapter}

\renewcommand\section{\@startsection{section}{1}{\z@}%
                                   {-3.5ex \@plus -1ex \@minus -.2ex}%
                                   {2.3ex \@plus.2ex}%
                                   {\normalfont\large\scshape}}

\newcommand\sectionis{\@startsection{section}{1}{\z@}%
                                   {-3.5ex \@plus -1ex \@minus -.2ex}%
                                   {2.3ex \@plus.2ex}%
                                   {\normalfont\large\scshape}}

\renewcommand\appendix{\par
  \renewcommand\chaptername{Appendixis}
  \setcounter{chapter}{0}
  \setcounter{section}{0}
  \gdef\@chapaa{\appendixname}
  \gdef\thechapter{\@roman\c@chapter}
 }

\makeatother
\begin{document}
  \tableofcontents
  \chapter{My First Chapter}
  \section{One}
  \sectionis{Two}
  \chapter{My Second Chapter}
  \appendix
  \chapter{First Appendix}
  \chapter{Second Appendix}
\end{document}

[Tex/LaTex] Titlesec and ACM conference format: How to get proper capitalization of sections

The definition you report states that the spacing before the section title is 10pt, extendable to 14pt and shrinkable to 8pt (the fourth argument to \@startsection) and that the spacing after the title is 4pt (fifth argument).

The negative values in -10\p@ \@plus -4\p@ \@minus -2\p@ tell LaTeX that the following paragraph should not be indented; the positive value in the fifth argument tells that this sectioning level is "displayed" rather than "run in".

So if you want no space after the section title and to reduce the space above you can do something like

\makeatletter
\def\section{%
  \@startsection{section}{1}{\z@}%
    {-6\p@ \@plus -2\p@ \@minus -1\p@}%Caleb Serafy
    {1sp}%Caleb Serafy
    {\baselineskip 14pt\secfnt\@ucheadtrue}%
}
\makeatother

Notice that I didn't say 0pt (or the equivalent 0\p@ or \z@ in a \makeatletter regime) for the fifth argument, but 1sp (the minumum positive length, which is unnoticeable by the naked eye). I've marked the modifications with your name, as did GM when changed the setup in the style sheet.

However, I don't think that the conference organizers will be happy about this, since they provide a stylesheet just to ensure uniform appearance of the papers.
