This isn’t always what you -need: for example, if you have nested enumerated lists with the outer -numbered and the inner labelled with letters, one might expect to want -to refer to items in the inner list as “2(c)”. (Remember, you can - -<a href="FAQ-enumerate.html">change the structure of list items</a>.) -The change is of course -possible by explicit labelling of the parent and using that label to -construct the typeset result — something like -<blockquote> -<pre> -\ref{parent-item}(\ref{child-item}) -</pre> -</blockquote><p> -which would be both tedious and error-prone. What’s more, it would be -undesirable, since you would be constructing a visual representation -which is inflexible (you couldn’t change all the references to elements -of a list at one fell swoop). -<p/>LaTeX in fact has a label-formatting command built into every label -definition; by default it’s null, but it’s available for the user to -program. For any label <<i>counter</i>> there’s a LaTeX internal -command <code>\</code><code>p@</code><<i><code>counter</i>></code>; for example, a label definition -on an inner list item is supposedly done using the command -<code>\</code><code>p@enumii{<code>\</code><code>theenumii</code>}</code>. Unfortunately, the internal -workings of this aren’t quite right, and you need to patch the -<code>\</code><code>refstepcounter</code> command: -<blockquote> - -<pre> -\renewcommand*\refstepcounter[1]{\stepcounter{#1}% - \protected@edef\@currentlabel{% - \csname p@#1\expandafter\endcsname - \csname the#1\endcsname - }% -} -</pre> -</blockquote><p> -With the patch in place you can now, for example, change the labels on -all inner lists by adding the following code in your preamble: -<blockquote> -<pre> -\makeatletter -\renewcommand{\p@enumii}[1]{\theenumi(#1)} -\makeatother -</pre> -</blockquote><p> -This would make the labels for second-level enumerated lists appear as -“1(a)” (and so on). The analogous change works for any counter that -gets used in a <code>\</code><code>label</code> command. -<p/>In fact, the <i>fncylab</i> package does all the above (including -the patch to LaTeX itself). With the package, the code above is -(actually quite efficiently) rendered by the command: -<blockquote> -<pre> -\labelformat{enumii}{\theenumi(#1)} -</pre> -</blockquote><p> -In fact, the above example, which we can do in several different ways, -has been rendered obsolete by the appearance of the <i>enumitem</i> -package, which is discussed in the answer about -<a href="FAQ-enumerate.html">decorating enumeration lists</a>. -<dl> -<dt><tt><i>enumitem.sty</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/enumitem.zip">macros/latex/contrib/enumitem</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/enumitem.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/latex/contrib/enumitem/">browse</a>) -<dt><tt><i>fncylab.sty</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/misc/fncylab.sty">macros/latex/contrib/misc/fncylab.sty</a> -</dl> -<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=labelformat">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=labelformat</a> -</body> |
