Voici la numérotation des titres basée uniquement sur les CSS (remplace le plugin numberedheadings)

Le code CSS suivant numérote tous les titres du wiki, ainsi que ceux de la table des matières.

Mettez-le :

• soit dans un fichier CSS de votre modèle (et une deuxième fois dans print.css, si vous voulez que la numérotation soit imprimable)
• ou dans un userstyle.css dans votre répertoire ./conf (ou userall.css s'il le faut) également utilisé pour la version imprimée):

Pour le modèle par défaut :

/lib/tpl/dokuwiki/css/userstyle.css

.dokuwiki .page {counter-reset: level1;}
.dokuwiki #dw__toc:before, .dokuwiki #dw__toc:after {counter-reset: level1; content: "";}
.dokuwiki #dw__toc h3:before{content: ""}

.dokuwiki .page h1, .dokuwiki ul.toc li.level1 {counter-reset: level2;}
.dokuwiki .page h2, .dokuwiki ul.toc li.level2 {counter-reset: level3;}
.dokuwiki .page h3, .dokuwiki ul.toc li.level3 {counter-reset: level4;}
.dokuwiki .page h4, .dokuwiki ul.toc li.level4 {counter-reset: level5;}
.dokuwiki .page h5, .dokuwiki ul.toc li.level5 {}

.dokuwiki .page h1:before,
.dokuwiki ul.toc li.level1 a:before {
    content: counter(level1) " ";
    counter-increment: level1;
}
.dokuwiki .page h2:before,
.dokuwiki ul.toc li.level2 a:before {
    content: counter(level1) "." counter(level2) " ";
    counter-increment: level2;
}
.dokuwiki .page h3:before,
.dokuwiki ul.toc li.level3 a:before {
    content: counter(level1) "." counter(level2) "." counter(level3) " ";
    counter-increment: level3;
}
.dokuwiki .page h4:before,
.dokuwiki ul.toc li.level4 a:before {
    content: counter(level1) "." counter(level2) "." counter(level3) "." counter(level4) " ";
    counter-increment: level4;
}
.dokuwiki .page h5:before,
.dokuwiki ul.toc li.level5 a:before {
    content: counter(level1) "." counter(level2) "." counter(level3) "." counter(level4) "." counter(level5) " ";
    counter-increment: level5;
}

/lib/tpl/monobook/user/screen.css

.dokuwiki #content {counter-reset: level1;}
.dokuwiki #dw__toc:before,
.dokuwiki #dw__toc:after {counter-reset: level1; content: "";}

.dokuwiki ul.toc li.level1 a:before {

    counter-increment: level1;
}
.dokuwiki #content h1.sectionedit1:before,
.dokuwiki ul.toc li.level1:first-child a:before {
    content: none;
}
.dokuwiki #content h2:before,
.dokuwiki ul.toc li.level2 a:before {
    content: counter(level1) "." counter(level2) " ";
    counter-increment: level2;
}
.dokuwiki #content h3:before,
.dokuwiki ul.toc li.level3 a:before {
    content: counter(level1) "." counter(level2) "." counter(level3) " ";
    counter-increment: level3;
}
.dokuwiki #content h4:before,
.dokuwiki ul.toc li.level4 a:before {
    content: counter(level1) "." counter(level2) "." counter(level3) "." counter(level4) " ";
    counter-increment: level4;
}
.dokuwiki #content h5:before,
.dokuwiki ul.toc li.level5 a:before {
    content: counter(level1) "." counter(level2) "." counter(level3) "." counter(level4) "." counter(level5) " ";
    counter-increment: level5;
}

Placez le fichier suivant dans l'un des CSS de votre thème (template) (ainsi que dans le print.css pour avoir la numérotation lors de l'impression) ou dans un userstyle.css dans votre répertoire ./conf :

Pour le thème monobook :

/doc/lib/tpl/monobook/user/screen.css
