ARCHITECTURE DU PROJET + * ------------------------- + * + * Le projet est organisé en plusieurs packages principaux : + * + * - com.terminal.emulator : Package racine contenant la classe Main et TerminalState + * - com.terminal.emulator.gui : Interface graphique Swing + * - com.terminal.emulator.filesystem : Système de fichiers virtuel + * - com.terminal.emulator.commands : Commandes du terminal + * - com.terminal.emulator.script : Moteur de scripts minimaliste + * - tests : Tests unitaires et d'intégration + * + * 2. SYSTÈME DE FICHIERS VIRTUEL + * ------------------------------ + * + * Le système de fichiers est implémenté avec une structure arborescente : + * + * - FileNode : Classe abstraite de base pour tous les nœuds + * - Directory : Répertoire, peut contenir d'autres FileNode + * - TerminalFile : Fichier texte avec contenu + * + * Chaque nœud a : + * - Un nom + * - Un parent (sauf la racine) + * - Une date de création + * - Une date de modification + * - Un chemin absolu + * + * 3. COMMANDES IMPLÉMENTÉES + * ------------------------- + * + * Commandes de base : + * - ls : Lister les fichiers (options : -l, -a, -r) + * - cd : Changer de répertoire + * - pwd : Afficher le répertoire courant + * - cat : Afficher le contenu d'un fichier + * - echo : Afficher du texte + * - touch : Créer un fichier ou mettre à jour sa date + * - mkdir : Créer un répertoire + * - rm : Supprimer un fichier + * - rmdir : Supprimer un répertoire vide + * - cp : Copier un fichier + * - mv : Déplacer/renommer un fichier + * - clear : Effacer l'écran + * - help : Afficher l'aide + * - exit : Quitter le terminal + * + * 4. MOTEUR DE SCRIPTS MINIMALISTE + * -------------------------------- + * + * Le langage de script supporte : + * + * - Variables : set var=value, $var + * - Conditions : if [ condition ]; fi + * * Comparaison : [ "$var" = "value" ] + * * Tests de fichiers : [ -f file ], [ -d dir ], [ -e path ] + * - Boucles : while [ condition ]; done + * - Boucles for : for var in list; do ... done + * - Commentaires : # commentaire + * - Commandes : toutes les commandes du terminal + * + * 5.

Ajouter les méthodes nécessaires + * + * Pour modifier l'interface graphique : + * 1. Modifier les classes dans le package gui + * 2. Respecter le pattern MVC + * + * 9. PERFORMANCES + * -------------- + * + * Le système est optimisé pour : + * - La navigation rapide dans le système de fichiers + * - L'exécution efficace des commandes + * - La gestion mémoire des fichiers + * - Le rendu fluide de l'interface + * + * 10. LIMITATIONS ET AMÉLIORATIONS POSSIBLES + * ---------------------------------------- + * + * Limitations actuelles : + * - Pas de support des permissions avancées + * - Pas de support des liens symboliques + * - Pas de support des tubes (pipes) + * - Pas de support des redirections avancées + * - Le script engine est basique + * + * Améliorations possibles : + * - Ajouter plus de commandes Unix + * - Améliorer le parseur de scripts + * - Ajouter le support des couleurs ANSI + * - Ajouter le support des raccourcis clavier + * - Ajouter la persistance du système de fichiers + * - Ajouter le support des plugins + * + * 11.
