This is an example of the general -problem of knowing where a particular bit of text lies: the output -routine is asynchronous, and (La)TeX will usually process quite a -bit of the “next” page before deciding to output any page. As a -result, the <code>page</code> counter (known internally in LaTeX as -<code>\</code><code>c@page</code>) is normally only reliable when you’re actually <em>in</em> -the output routine. -<p/>The solution is to use some version of the <code>\</code><code>label</code> mechanism to -determine which side of the page you’re on; the value of the page -counter that appears in a <code>\</code><code>pageref</code> command has been inserted in -the course of the output routine, and is therefore safe. -<p/>However, <code>\</code><code>pageref</code> itself isn’t reliable: one might hope that -<pre> -\ifthenelse{\isodd{\pageref{foo}}}{odd}{even} -</pre> -would do the necessary, but both the <i>babel</i> and -<i>hyperref</i> packages have been known to interfere with the -output of <code>\</code><code>pageref</code>; be careful! -<p/>The <i>changepage</i> package needs to provide this functionality for -its own use, and therefore provides a command <code>\</code><code>checkoddpage</code>; this -sets a private-use label, and the page reference part of that label is -then examined (in a <i>hyperref</i>-safe way) to set a conditional -<code>\</code><code>ifoddpage</code> true if the command was issued on an odd page. The -<i>memoir</i> class has the same command setting a conditional -<code>\</code><code>ifoddpage</code>. Of course, the <code>\</code><code>label</code> contributes to LaTeX’s -“Rerun to get cross-references right” error messages... -<p/>The (older) <i>chngpage</i> provides the same facilities (though it -provides a <code>\</code><code>ifcpoddpage</code> command; <i>changepage</i> (whose -functions are extracted from the author’s <i>memoir</i> class) is the -designated successor to <i>chngpage</i>. -<p/>The Koma-Script classes have an <code>addmargin*</code> environment -that also provides the sorts of facilities that the <i>chngpage</i> -offers. Koma-Script’s supporting command is -<code>\</code><code>ifthispageodd{<true>}{<false>}</code> executes different things -depending on the page number. -<dl> -<dt><tt><i>changepage.sty</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/misc/changepage.sty">macros/latex/contrib/misc/changepage.sty</a> -<dt><tt><i>chngpage.sty</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/misc/chngpage.sty">macros/latex/contrib/misc/chngpage.sty</a> -<dt><tt><i>KOMA script bundle</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/koma-script.zip">macros/latex/contrib/koma-script</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/koma-script.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/latex/contrib/koma-script/">browse</a>) -<dt><tt><i>memoir.cls</i></tt><dd><a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/memoir.zip">macros/latex/contrib/memoir</a> (<a href="ftp://cam.ctan.org/tex-archive/macros/latex/contrib/memoir.tar.gz">gzipped tar</a>, <a href="http://www.tex.ac.uk/tex-archive/macros/latex/contrib/memoir/">browse</a>) -</dl> -<p/><p>This question on the Web: <a href="http://www.tex.ac.uk/cgi-bin/texfaq2html?label=oddpage">http://www.tex.ac.uk/cgi-bin/texfaq2html?label=oddpage</a> -</body> |
