I have been using $latex \LaTeX$ since I was 17 and still love it. But one thing has been bugging me for a long time. For a while I had been manually tweaking documents to get proper linebreaks when using the \texttt{} macro. Now I had finally come to the point where this did not work any longer. A search gave me this snippet:

\renewcommand{\texttt}[1]{%
 \begingroup
 \ttfamily
 \begingroup\lccode`~=`/\lowercase{\endgroup\def~}{/\discretionary{}{}{}}%
 \begingroup\lccode`~=`[\lowercase{\endgroup\def~}{[\discretionary{}{}{}}%
 \begingroup\lccode`~=`.\lowercase{\endgroup\def~}{.\discretionary{}{}{}}%
 \catcode`/=\active\catcode`[=\active\catcode`.=\active
 \scantokens{#1\noexpand}%
 \endgroup
 }

It works great!
