I have long paths as section headings and need proper line breaks. I don't need hyphens or any break rules.

\section{Important Paths}
\subsection{trunk/Averylong/Bverylong/Cverylongverylong/Dverylongverylong/Everylong/Fverylong\_file\_Name.txt}
\subsection{trunk/Averylong/Bverylong/Cverylongverylong/Dverylongverylong/Everylong/Fverylong file Name.txt}

The only way I can archive this is to add a hspace after each char. The output is exactly what I want it to be. But this doesn't seem to be a sane solution. 

\subsection{t\hspace{0pt}r\hspace{0pt}u\hspace{0pt}n\hspace{0pt}k\hspace{0pt}/\hspace{0pt}A\hspace{0pt}v\hspace{0pt}e\hspace{0pt}r\hspace{0pt}y\hspace{0pt}l\hspace{0pt}o\hspace{0pt}n\hspace{0pt}g\hspace{0pt}/\hspace{0pt}B\hspace{0pt}v\hspace{0pt}e\hspace{0pt}rvy\hspace{0pt}l\hspace{0pt}o\hspace{0pt}n\hspace{0pt}g\hspace{0pt}/\hspace{0pt}C\hspace{0pt}v\hspace{0pt}e\hspace{0pt}r\hspace{0pt}y\hspace{0pt}l\hspace{0pt}o\hspace{0pt}n\hspace{0pt}g\hspace{0pt}v\hspace{0pt}e\hspace{0pt}r\hspace{0pt}y\hspace{0pt}l\hspace{0pt}o\hspace{0pt}n\hspace{0pt}g\hspace{0pt}/\hspace{0pt}D\hspace{0pt}v\hspace{0pt}e\hspace{0pt}r\hspace{0pt}y\hspace{0pt}l\hspace{0pt}o\hspace{0pt}n\hspace{0pt}g\hspace{0pt}v\hspace{0pt}e\hspace{0pt}r\hspace{0pt}y\hspace{0pt}l\hspace{0pt}o\hspace{0pt}n\hspace{0pt}g\hspace{0pt}/\hspace{0pt}E\hspace{0pt}v\hspace{0pt}e\hspace{0pt}r\hspace{0pt}y\hspace{0pt}v\hspace{0pt}l\hspace{0pt}o\hspace{0pt}n\hspace{0pt}g\hspace{0pt}/\hspace{0pt}F\hspace{0pt}v\hspace{0pt}e\hspace{0pt}r\hspace{0pt}y\hspace{0pt}l\hspace{0pt}o\hspace{0pt}n\hspace{0pt}g\hspace{0pt} \hspace{0pt}f\hspace{0pt}i\hspace{0pt}l\hspace{0pt}e\hspace{0pt} \hspace{0pt}N\hspace{0pt}a\hspace{0pt}m\hspace{0pt}e\hspace{0pt}.\hspace{0pt}t\hspace{0pt}x\hspace{0pt}t\hspace{0pt}}

The output is:

1.1 even reaches over the end of the pdf.

I have created a simple document on sharelatex.

Is there a simple solution to archive this?

//UPDATE: As suggested by by David Carlisle I applied the raggedright and slash approach. It works fine for the section headings but breaks the toc for some paths. E.g.:

\subsection{trunk\slash trunk\slash Averylong\slash Bverylongverylong\slash Cverylongverylong\slash AdditionalCompilerSupportDefines.h}
this one breaks the toc

I'v created an other sharelatex document to illustrate the toc problem.

//UPDATE: Resolved: The package tocstyle provides a hook to apply raggedright to the toc. See https://tex.stackexchange.com/a/45164/115878 & sharelatex document

  • (1) welcome, (2) \path from the url package may help, need to test with your doc. \protect\path{trunk/Averylong/Bverylong/Cverylongverylong/Dverylongverylong/Everylong/Fverylong_file_Name.txt} wotks fine. Note there is then no need to escape _ – daleif Oct 7 '16 at 10:35
  • Thanks daleif but this breaks the section style as it uses typwriter font. – No3x Oct 7 '16 at 10:41
  • Then you need someone to help you configure \path, that is a different matter of which I have to time at the moment, sorry – daleif Oct 7 '16 at 10:47
  • Had a short break, this seems to work \DeclareUrlCommand\sfpath{\def\UrlFont{\fontfamily{phv}}}, note the \sffamily in your headings are probably being overwritten by \fontfamily. – daleif Oct 7 '16 at 11:08
  • use \slash instead of / and line breaking will be allowed – David Carlisle Oct 7 '16 at 11:13

I would allow breaking only at / and set the headings raggedright:

  • Thanks! This works fine for sections as required but breaks the toc. Try with this: \subsection{trunk\slash trunk\slash Averylong\slash Bverylongverylong\slash Cverylongverylong\slash AdditionalCompilerSupportDefines.h} this one breaks the toc – No3x Oct 7 '16 at 14:24
  • @No3x well yes you'd want to set the toc raggedright as well I don't know scr* classes that well, probably has some built in customisation for that. – David Carlisle Oct 7 '16 at 14:39
  • thanks for the hint. I'm very new to customize latex behaviour. I will try to set this to the toc as well somehow. – No3x Oct 7 '16 at 14:54
  • I was able to resolve this. See the updated question. – No3x Oct 10 '16 at 7:58
