Tengo un problema con los títulos de subsecciones o subsecciones largos: \\no funcionan.
Como soy nuevo en Latex, adopté esta hermosa plantilla.http://www.fluortools.com/misc/LaTeXtemplatey lo modifiqué para mis necesidades.
Sin embargo, en este momento, estoy atascado con saltos de línea en los títulos de las subsecciones.
Aquí hay un MWE:
\documentclass[a4paper,12pt,oneside]{scrbook}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[bitstream-charter]{mathdesign}
\usepackage[scaled]{berasans}
\usepackage[scaled]{beramono}
\usepackage[english]{babel}
\usepackage[left=3cm,right=3cm,top=2.5cm,bottom=3cm,includehead,headheight=13.6pt]{geometry}
\usepackage{titlesec}
\usepackage{tikz}
\usetikzlibrary{calc,decorations,decorations.pathmorphing,arrows,matrix,positioning,patterns}
\usepackage{xcolor}
\selectcolormodel{cmyk}
\newcommand\boxedSection[3]{{%
%
\begin{tikzpicture}[inner sep=#3,line width=1.0pt]
\node[anchor=east,rectangle,draw] at (0,0) (counter) {\textbf{#2}};
\draw (counter.south west) ++(.0pt,.5pt)-- ++($(\linewidth,0) - (2.5pt,0)$);
\node [right of=counter,anchor=west]{#1};
\end{tikzpicture}
}}
\newcommand\boxedSectionB[3]{{%
%
\begin{tikzpicture}[inner sep=#3,line width=1pt]
\node[anchor=east,rectangle,draw,fill=black] at (0,0) (counter) {\color{white}\textbf{#2}};
\draw (counter.south west) ++(.0pt,.5pt)-- ++($(\linewidth,0) - (2.5pt,0)$);
\node [right of=counter,anchor=west]{#1};
\end{tikzpicture}
}}
\newcommand\boxedsection[1]{\boxedSectionB{#1}{\thesection}{2mm}}
\newcommand\boxedsubsection[1]{\boxedSection{#1}{\thesubsection}{1.7mm}}
\newcommand\boxedsubsubsection[1]{\boxedSection{#1}{\thesubsubsection}{1.5mm}}
\titleformat{\section}[hang]%
{\usekomafont{section}}%
{}%
{.0em}%
{\filright\boxedsection}%
\titleformat{\subsection}[hang]%
{\usekomafont{subsection}}%
{}%
{.0em}%
{\filright\boxedsubsection}%
\titleformat{\subsubsection}[hang]%
{\usekomafont{subsubsection}}%
{}%
{.0em}%
{\filright\boxedsubsubsection}%
\titlespacing{\section}{0pt}{1.5cm}{-1cm}
\titlespacing{\subsection}{0pt}{1.5cm}{-1cm}
\titlespacing{\subsubsection}{0pt}{6pt}{6pt}
\titlespacing{\paragraph}{}{0pt}{0pt}
\begin{document}
\subsection{This title is really really really long so I'd liked to have a \\line break but instead is just go on and on ...}
\end{document}
Tan pronto como elimino la parte boxedSection en el formato de título, el salto de línea \\funciona nuevamente, pero, por supuesto, también se elimina el bonito diseño.
¿Podría alguien modificar el MWE para que el salto de línea vuelva a funcionar, pero se mantiene el bonito diseño?
¡¡Muchas gracias!!

Entonces encontré una solución que funciona bien para mi propósito. Como sugiere touhami, agregué text width=13cmy anchor=west
eliminé la línea en boxedSection mientras dejé boxedSectionB sin cambios. Entonces el código se ve así:
\newcommand\boxedSection[3]{{%
%
\begin{tikzpicture}[inner sep=#3,line width=1.0pt]
\node[anchor=east,rectangle,draw] at (0,0) (counter) {\textbf{#2}};
\node [right of=counter,anchor=west,text width=13cm]{#1};
\end{tikzpicture}
}}
Y los resultados se ven así:

Aquí hay otra sugerencia sin paquete titlesec. Ahora no hay reglas debajo de los títulos.

titlesecTenga en cuenta que no se recomienda el uso del paquete junto con una clase KOMA-Script. Recibirá advertencias mediante KOMA-Script y titlesec.
Aquí hay una sugerencia sin titlesecy tikzque necesita al menos la versión 3.19a de KOMA-Script (actual en CTAN).
