Xcasfr.html est une interface javascript optimisée pour Firefox
du système de calcul formel
<a
href="http://www-fourier.ujf-grenoble.fr/~parisse/giac/emgiac.tgz">Giac/Xcas</a>
compilé par emscripten (l'éditeur de
programme de cette interface
utilise <a href="http://codemirror.net">CodeMirror</a>).
Il n'a pas besoin de serveur, il s'exécute localement
(avec le moteur javascript de votre navigateur qui doit être récent,
mettez-le à jour pour avoir de bonnes performances, il faut
aussi avoir au moins 300M de RAM disponible)
à partir du code du CAS (13M) qui est téléchargé
une fois. Le prix à payer pour cette simplicité
est la vitesse, le code est au moins 2 fois plus lent, parfois
beaucoup plus (par exemple 8 fois plus lent pour un calcul intensif
de bases de Groebner).
La plupart du temps, cela n'est pas vraiment
genant, mais
si vous devez exécuter un gros calcul, il
vaut mieux installer

Tapez votre calcul dans la ligne de commande en bas de la page

Vous pouvez utiliser le clavier scientifique
(bouton <tt>123</tt> au-dessus de la ligne de commande)
et les assistants du bouton <tt>menu</tt>.
Validez avec Entrée ou le bouton <tt>ok</tt> en vert.
<br>
Pour obtenir de l'aide, tapez un nom de commande puis le
bouton <tt>?</tt>.
Pour trouver une commande, cliquez sur un des thèmes
ci-dessous, ou consultez le

commandes de Xcas</a>

<div id="tutointerface" style="display:none">
Cette feuille de calcul est composée du haut vers le bas de:
<ul>
<li> un logo Xcas et un panel de boutons permettant de restaurer/sauvegarder
une session et de gérer l'historique, la corbeille et les
variables. Au lancement de Xcas, le panel est
réduit à insertion d'une session, consultation des
manuels, configuration et restauration de la session
précédente.
Dès que vous avez validé une commande, il apparait
<ul>
<li> un lien Clone
qui permet de <strong>cloner</strong> une session existante.
A utiliser si le noyau de calcul formel a crashé ou
pour copier-coller dans une page web, ou pour exécuter
dans Xcas natif.
<li> un lien E-mail qui permet de <strong>partager
votre session</strong> par e-mail.
</li>
</ul>
</li>
<li> une zone d'<strong>aide</strong>, qui contient des courtes description des
commandes dont vous avez demandé la syntaxe.
</li>
<li> un <strong>historique</strong> (vide au début).
Les lignes de commande y apparaissent en noir, les résultats en
bleu, les boutons ↑ et ↓ permettent de déplacer un niveau
dans l'historique, le bouton bleu ~ permet d'avoir une valeur
numérique du résultat. Vous pouvez modifier une ligne
de commande de l'historique et valider en cliquant sur le bouton ok
ou la touche Entree. Vous
pouvez placer un niveau dans la corbeille avec le bouton
d'effacement à droite du niveau (pour le restaurer,
cliquer sur le bouton Restaure, pour l'effacer
définitivement cliquer sur le bouton Vide).
</li>
<li> une <strong>ligne de commande</strong>, on y tape des commandes
ou des programmes Xcas, et on
valide en cliquant sur le bouton ok ou en tapant Entree. Pour passer
à la ligne dans un programme, tapez Shift-Entree au clavier
ou utilisez le bouton <tt>\n</tt> du clavier scientifique.
<br>
Par exemple, tapez un calcul simple comme <tt>1/2+1/3</tt>
ou <tt>sin(pi/4)</tt> ou <tt>sin(pi/4.0)</tt>.
<br>
Pour vous aider à remplir la ligne de commande,
vous pouvez cliquer sur le bouton 123 qui fait apparaitre
le <strong>clavier scientifique</strong> et sur le bouton menu
qui contient des commandes
fréquemment utiliées et des assistants
(déplacez la souris près des boutons pour
une description de leur action).
<br>
Si vous connaissez le nom d'une commande,
vous pouvez taper (le début) du nom d'une commande
(par exemple <tt>factor</tt>) puis
la touche <button class="bouton">F1</button> ou <button class="bouton">Tab</button>
ou cliquer sur le bouton <button class="bouton">?</button>
pour obtenir une
<strong>aide courte</strong> sur la commande (si elle
est complète) ou des suggestions de noms de
commande (sinon).
<br>
Par exemple, cliquer sur le bouton <tt>menu</tt> puis sur le bouton
<tt>factor</tt> puis tapez sur <tt>?</tt>, observez l'aide
en haut, cliquez sur un des exemples ou completez avec
x^4-1 puis tapez Entree.
<br>
Sur mobile, vous pouvez
<strong>sélectionner</strong> du texte en laissant le doigt appuyé
sur un mot, puis taper sur l'icone avec des ciseaux (pour couper) ou
avec deux feuilles (pour copier), pour coller le presse-papier,
laisser le doigt appuyé puis taper sur l'icone avec une
feuille. Vous pouvez aussi appuyer sur les boutons <tt>beg</tt>
et <tt>end</tt> pour marquer le début et la fin de la
sélection, puis optionnellement sur <tt>del</tt> pour
effacer, puis sur <tt>cp</tt> pour coller ce que vous aviez
sélectionné. <br>
Vous pouvez entrer un <strong>commentaire</strong> en tapant une ligne de commande
commencant par <tt>//</tt> (vous pouvez utiliser des commandes de
balisage HTML dans un commentaire).
</li>
<li>
une <strong>console</strong> qui affiche des messages du CAS :
erreurs de syntaxe mais aussi lors
d'un calcul en mode pas-à-pas, par exemple d'une
dérivée.
La console n'est pas visible si elle est vide.
Vous pouvez effacer la console ou ajuster sa taille verticale.
</li>
<li>
une zone affichant des <strong>graphes 3d</strong>
lorsqu'on exécute une commande
ayant une sortie graphique 3d. Cette zone n'est pas visible s'il n'y
a pas de graphique 3d.
</li>
</ul>
A tout moment, vous pouvez <strong>sauvegarder</strong> l'historique,
avec le nom de session affiché à droite du bouton
<tt>Sauve</tt>
(par défaut <tt>session</tt>).
Une session sauvegardée
s'ouvre ensuite avec le bouton Charger.
Les sauvegardes sont faite dans les cookies du
navigateur avec un nom de cookie commencant par <tt>xcas__</tt>, vous
pouvez les effacer depuis la gestion de la Vie privée de votre
navigateur (attention, la sauvegarde ne fonctionne pas en utilisation locale avec
Chrome sauf si Chrome est lancé avec l'option <tt>--enable-file-cookies</tt>).
Vous pouvez aussi <strong>exporter</strong> la feuille de calcul (sauf
sur smartphone), l'export occupe plus de place mais
permet de publier le fichier HTML comme une page autonome.
Vous pouvez sauvegarder les graphes 2d au format SVG avec le bouton
save à droite du graphe. Le fichier SVG créé
est au format 1.2 (il utilise la balise
<tt>vector-effect="non-scaling-stroke"</tt> qui n'est pas compris
par tous les visualisateurs ou convertisseurs).
<br>
Sous Firefox, pour pouvoir
choisir l'emplacement de sauvegarde et écraser
une version antérieure : cocher Toujours demander...
dans Préférences,
Général, Téléchargements.
<br>
Vous pouvez ouvrir (partiellement) une session existante Xcas en la clonant
(menu Fich, Clone du programme Xcas, ou en ligne de commande
<tt>xcas --online nom_fichier.xws</tt>)
<br>
Notez que Chrome (et plus généralement
le navigateur installé par défaut sur votre appareil)
est beaucoup plus lent que Firefox pour
faire les calculs (5 fois plus lent environ), en particulier le
premier calcul dure une bonne dizaine de secondes. De plus, Chrome
n'a pas de support natif pour afficher les formules en 2d en mathml,
il faut alors charger MathJax ce qui nécessite
un accès réseau.
<br>
<strong>Il est donc recommendé de télécharger
Firefox et d'exécuter Xcas depuis Firefox</strong>
<br>
<strong>Remarque</strong> :
Vous pouvez revenir travailler sur cette page meme si vous n'avez pas de
réseau disponible, car les ressources nécessaires sont
automatiquement placéees dans le cache de votre navigateur.
Vous pouvez optionnellement
<strong>installer</strong> Xcas sur votre appareil,
dézippez
<a href="http://www-fourier.ujf-grenoble.fr/~parisse/giac/xcashtml.zip">
xcashtml.zip</a> et
cherchez <tt>xcasfr.html</tt>, depuis <a
