<span id="index-Line-breaking_002c-and-urls"></span>
<span id="index-Breakpoints-within-urls"></span>
<p>TeX allows line breaking within urls at only a few characters
(which are special in urls): ‘<samp>&</samp>’, ‘<samp>.</samp>’, ‘<samp>#</samp>’, ‘<samp>?</samp>’,
and ‘<samp>/</samp>’ (but not between two ‘<samp>/</samp>’ characters). A tiny amount
of stretchable space is also inserted around these characters to help
with line breaking.
</p>
<p>For HTML output, modern browsers will also do line breaking within
displayed urls. If you need to allow breaks at other characters you
can insert <code>@/</code> as needed (see <a href="Line-Breaks.html">Line Breaks</a>).
</p>
<span id="index-urefbreakstyle"></span>
<p>By default, in TeX any such breaks at special characters will occur
after the character. Some people prefer such breaks to happen before
the special character. This can be controlled with the
<code>@urefbreakstyle</code> command (this command has effect only in
TeX):
</p>
<div class="example">
<pre class="example">@urefbreakstyle <var>how</var>
</pre></div>
<p>where the argument <var>how</var> is one of these words:
</p>
<span id="index-after_002c-value-for-_0040urefbreakstyle"></span>
<span id="index-before_002c-value-for-_0040urefbreakstyle"></span>
<span id="index-none_002c-value-for-_0040urefbreakstyle"></span>
<dl compact="compact">
<dt>‘<samp>after</samp>’</dt>
<dd><p>(the default) Potentially break after the special characters.
</p></dd>
<dt>‘<samp>before</samp>’</dt>
<dd><p>Potentially break before the special characters.
</p></dd>
<dt>‘<samp>none</samp>’</dt>
<dd><p>Do not consider breaking at the special characters at all; any potential
breaks must be manually inserted.
</p></dd>
