\titlesec y Chapter§ion faltan error cero

Question

He buscado y buscado aquí una posible respuesta, pero me estoy quedando corto. Incluso hice referencia a las instrucciones de titlesec .pdf y todavía no tengo ni idea. Tengo un problema con mi \chaptercuerpo principal y digo que le falta un cero.

Chapter 1.
! Missing number, treated as zero.
<to be read again> 
                   \relax 
l.39 \chapter{Spanning Tree Protocol Concepts}

El error está en mi primer capítulo.

Estoy escribiendo mis notas y para cada capítulo quiero mostrar "capítulo 1" y luego "este es el título del capítulo". Las secciones no las quiero numeradas, por eso uso un archivo \section*. ¿Alguna idea?

Answer 1

El comando \titlespacingespera tres longitudes.

entonces deberían ser algo como

\titlespacing{\chapter}{0pt}{0pt}{4pt}

y

\titlespacing{\section}{0pt}{5pt}{5pt}

También tienes /end{document}en lugar de\end{document}

No sé qué intentas lograr, pero este es tu MWE modificado:

Producción

Tenga en cuenta que también le falta una longitud en

\titleformat{\section}
    {\normalfont\Large\bfseries}
    {\thesection}{}{}

debería ser algo así como

\titleformat{\section}
    {\normalfont\Large\bfseries}
    {\thesection}{1em}{}

Simplemente no te diste cuenta porque en el MWE sólo tienes secciones sin numerar.

Answer 2

Sugeriría una pequeña mejora: las líneas que comienzan con un guión tienen una estructura detallada, por lo que solía enumitemformatear itemizecon endashes. Faltaba una longitud como cuarto argumento de \titleformat{\section}{…}:

\documentclass{report}

\usepackage{bookmark}
\usepackage{booktabs}
\usepackage{titlesec}
\usepackage{parskip}
%\usepackage{indentfirst} used to indent first paragraph

\setlist[itemize, 1]{etiqueta = \textendash}
