The process of resetting is -done automatically, when the “master” counter is stepped (when the -<code>\</code><code>chapter</code> command that starts chapter <<i>n</i>> happens, the -<code>chapter</code> counter is stepped, and all the dependent counters are set -to zero). -<p/>How would you do that for yourself? You might want to number -algorithms per section, or corollaries per theorem, for example. If -you’re defining these things by hand, you declare the relationship -when you define the counter in the first place: -<blockquote> -<code>\</code><code>newcounter{</code><em>new-name</em><code>}[</code><em>master</em><code>]</code> -</blockquote><p> -says that every time counter <<i>master</i>> is stepped, counter -<<i>new-name</i>> will be reset. -<p/>But what if you have an uncooperative package, that defines the -objects for you, but doesn’t provide a programmer interface to make -the counters behave as you want? -<p/>The <code>\</code><code>newcounter</code> command uses a LaTeX internal command, and you -can also use it: -<blockquote> -<code>\</code><code>@addtoreset{</code><em>new-name</em><code>}{</code><em>master</em><code>}</code> -</blockquote><p> -(but remember that it needs to be between <code>\</code><code>makeatletter</code> and -<code>\</code><code>makeatother</code>, or in a package of your own). -<p/>The <i>chngcntr</i> package encapsulates the <code>\</code><code>@addtoreset</code> -command into a command <code>\</code><code>counterwithin</code>. So: -<blockquote> -<pre> -\counterwithin*{corrollary}{theorem} -</pre> -</blockquote><p> -will make the corollary counter slave to theorem counters. The -command without its asterisk: -<blockquote> -<pre> -\counterwithin{corrollary}{theorem} -</pre> -</blockquote><p> -will do the same, and also redefine <code>\</code><code>thecorollary</code> as -<<i>theorem number</i>>.<<i>corollary number</i>>, which is a good scheme -if you ever want to refer to the corollaries — there are potentially -many “corollary 1” in any document, so it’s as well to tie its number -to the counter of the theorem it belongs to. This is true of pretty -much any such counter-within-another; if you’re not using the -<i>chngcntr</i>, refer to the answer to -<a href="FAQ-the-commands.html">redefining counters’ <code>\</code><code>the-</code>commands</a> for -the necessary techniques. -<p/>Note that the technique doesn’t work if the master counter is <code>page</code>, -the number of the current page. The <code>page</code> counter is stepped deep -inside the output routine, which usually gets called some time after -the text for the new page has started to appear: so special -techniques are required to deal with that. One special case is dealt -with elsewhere: <a href="FAQ-footnpp.html">footnotes numbered per page</a>. One -of the techniques described there, using package <i>perpage</i>, -may be applied to any counter. The command: -<blockquote> -<code>\</code><code>MakePerPage{</code><em>counter</em><code>}</code> -</blockquote><p> -will cause <<i>counter</i>> to be reset for each page. The package uses -a label-like mechanism, and may require more than one run of LaTeX -to stabilise counter values — LaTeX will generate the usual -warnings about labels changing. -<dl> -<dt><tt><i>chngcntr.sty</i></tt><dd><a href="http://mirror.ctan.org/macros/latex/contrib/chngcntr.zip">macros/latex/contrib/chngcntr</a> (or <a href="http://mirror.ctan.org/macros/latex/contrib/chngcntr/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/chngcntr.html">catalogue entry</a> -<dt><tt><i>perpage.sty</i></tt><dd>Distributed as part <a href="http://mirror.ctan.org/macros/latex/contrib/bigfoot.zip">macros/latex/contrib/bigfoot</a> (or <a href="http://mirror.ctan.org/macros/latex/contrib/bigfoot/">browse the directory</a>); <a href="http://mirror.ctan.org/help/Catalogue/entries/perpage.html">catalogue entry</a> -</dl> -<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=addtoreset">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=addtoreset</a> -</body> |
