Avertissement
Ce code présente une manière possible d'implémenter un compilateur, et certains choix peuvent être discutés.Cependant, il peut donner des pistes pour démarrer, ou approcher certains concepts, et je tenterais par la suite de mettre à jour le code.
Utilisation de l'explorateur de code
- Navigation :
- Un clic sur une icône de répertoire ouvre ce répertoire pour en afficher les fichiers.
- Lorsque le répertoire en cours ne contient pas de sous-répertoires il est possible de remonter vers le répertoire parent.
- La structure de répertoires en treetable (tableau en forme d'arborescence) n'est plus possibledans cette version.
- Un clic sur une icône de fichier ouvre ce fichier pour en afficher le code avec la coloration syntaxique adaptée en fonction du langage principal utilisé dans le fichier.
- Affichage :
- Il est possible de trier les répertoires ou les fichiers selon certains critères (nom, taille, date).
- Actions :
- Les actions possible sur les fichiers dépendent de vos droits d'utilisateur sur le site. Veuillez activer le mode utilisateur pour activer les actions.
