This label can then be referred to in a markup, to get the number of the page where the marked point is placed, using the <code>\page-ref</code> markup command. <pre class="verbatim"> \header { tagline = ##f } \book { \label #'firstScore \score { { c'1 \pageBreak \mark A \label #'markA c' } } \markup { The first score begins on page \page-ref #'firstScore "0" "?" } \markup { Mark A is on page \page-ref #'markA "0" "?" } } </pre> <p> <a href="../77/lily-658a7eb9.ly"> <img align="middle" border="0" src="../77/lily-658a7eb9.png" alt="[image of music]"> </a> </p> <p>The <code>\page-ref</code> markup command takes three arguments: <ol type=1 start=1> <li>the label, a scheme symbol, eg. <code>#'firstScore</code>; <li>a markup that will be used as a gauge to estimate the dimensions of the markup; <li>a markup that will be used in place of the page number if the label is not known; </ol> <p>The reason why a gauge is needed is that, at the time markups are interpreted, the page breaking has not yet occurred, so the page numbers are not yet known. To work around this issue, the actual markup interpretation is delayed to a later time; however, the dimensions of the markup have to be known before, so a gauge is used to decide these dimensions. If the book has between 10 and 99 pages, it may be "00", ie. a two digit number. <p class="noindent"> <h5 class="subsubheading">Predefined commands</h5> <p><a name="index-g_t_005clabel-2405"></a><a name="index-g_t_005clabel-2406"></a> <code>\label</code> <a name="index-g_t_005cpage_002dref-2407"></a><a name="index-g_t_005cpage_002dref-2408"></a> <code>\page-ref</code> <!-- footer_tag --><br><hr> <div class="node"> <p> Next: <a rel="next" accesskey="n" href="Table-of-contents.fr.html#Table-of-contents">Table of contents</a>, Previous: <a rel="previous" accesskey="p" href="Custom-titles.fr.html#Custom-titles">Custom titles</a>, Up: <a rel="up" accesskey="u" href="Titles-and-headers.fr.html#Titles-and-headers">Titles and headers</a> </div> <div style="background-color: #e8ffe8; padding: 2; border: #c0ffc0 1px solid;"> <p> <font size="-1"> Cette page documente LilyPond-2.11.57 (branche de développement). <br> <address> Rapportez toute anomalie en français à <a href="mailto:lilypond-user-fr@gnu.org">lilypond-user-fr@gnu.org</a> ou en anglais à <a href="http://post.gmane.org/post.php?group=gmane.comp.gnu.lilypond.bugs">http://post.gmane.org/post.php?group=gmane.comp.gnu.lilypond.bugs</a> </address> <br> Vos <a href="http://lilypond.org/web/devel/participating/documentation-adding">suggestions à propos de la documentation</a> sont les bienvenues. </font> </p> </div> <P> Autres langues : <a href="Reference-to-page-numbers.es.html">español</a>. <BR> </P> </BODY></html>
