Push long words in a new line

Question

I have sometimes very long words, which are for example method names and so on.

Is there any possibility to force LaTeX to push them to a new line, if they overflow the margins?

It is possible to push them into a new line, because I know in my document aren't words which are too long for a line.

Here a mini example which produce the problem:

\documentclass{scrartcl}

\begin{document}
\section{Test}
Finally there is a simple solution using \textsc{\textbf{XMLResource.OPTION\_RECORD\_UNKNOWN\_FEATURE}} option. And the
text must go on \ldots.
\par
And another example the show must go on, but we have too less text (\textbf{createUnspecifiedNodeWarningMarker} and
\textbf{createUnspecifiedNodeErrorMarker}, sdjklashjksa \textbf{createUnspecifiedLinkWarningMarker} and
\textbf{createUnspecifiedLinkErrorMarker}).
\end{document}

Thanks for any advices.

Answer 1

it seems that the text involved is highly technical. under the circumstances, it is probably best to set it flush left and suppress hyphenation entirely for the duration.

this code should do the job for a limited section of the text.

\begin{flushleft}
\hyphenpenalty=10000
\exhyphenpenalty=10000
 <de-hyphenated text here>
\end{flushleft}

if such text is justified, and the population of long technical terms is greater than that of ordinary text, the spacing in the ordinary text becomes very uneven and is consequently harder to comprehend than ragged right text.

sloppypar, as suggested in a comment, justifies the text within the environment. this would work if there are more ordinary words than long ones, and the long ones don't occur in inconvenient locations within the lines. a test with the affected material, trying both techniques side by side, will quickly make it clear which is preferable in a given situation.

Answer 2

If your text has a lot of these words it's probably best to go with fully unjustified text as in the first answer, but sometimes you have text which would look best justified apart from occasional outcrops of unbreakable words. In these cases you can just use a definition as below which allows lines to break short before such words but otherwise tries to justify both paragraph margins.

\documentclass{scrartcl}

\newenvironment{foo}
{\par
\hyphenpenalty=10000
\exhyphenpenalty=10000
}
{\par}

\newcommand\lword[1]{\leavevmode\nobreak\hskip0pt plus\linewidth\penalty50\hskip0pt plus-\linewidth\nobreak\textbf{#1}}
\begin{document}
\section{Test}
\begin{foo}
Finally there is a simple solution using \textsc{\lword{XMLResource.OPTION\_RECORD\_UNKNOWN\_FEATURE}} option. And the
text must go on \ldots.

And another example the show must go on, but we have too less text (\lword{createUnspecifiedNodeWarningMarker} and
\lword{createUnspecifiedNodeErrorMarker}, sdjklashjksa \lword{createUnspecifiedLinkWarningMarker} and
\lword{createUnspecifiedLinkErrorMarker}).
More text, more text. More text, more text. More text, more text.
More text, more text. More text, more text. More text, more text.
More text, more text. More text, more text. More text, more text.
\end{foo}
\end{document}

Note, unrelated to the linebreaking issue the standard fonts don't include a bold small caps, so you get a font warning and bold normal text for the first case.
