| ''' | |
| An Epitech norme checker | |
| Usage: python norme.py <files to scan> [-nocheat] [-verbose] [-score] [-libc] | |
| -verbose: affiche les messages impossible d\'ouvrir | |
| -nocheat: desactive la detection de la triche | |
| -score: affiche le nombre de faute de norme | |
| -libc: active la verification des fonctions de la libc | |
| -malloc: desactive le controle du malloc | |
| -printline: affiche la ligne provoquant une erreur | |
| -return: active verifier le retour des fonctions (return ;) | |
| -comment: ne pas verifier les commentaire | |
| Non geree: | |
| - Indentation | |
| - +<escape> | |
| - verification de la presence de gl_ | |
| _ macro multiligne | |
| _ initialisation de variable a la declaration | |
| _ separation initialisation de variable et code | |
| A modifier: | |
| Fonction checkant la protection contre la double inclusion des .h . | |
| Appel ligne 163. | |
| Bug: | |
| Il est arrivee que le checker ne trouve aucune faute alors qu\'il en existe, si | |
| ce bug vous arrive maillez moi. | |

Attention ! Ce script récupère le fichier passwd (contenant vos mots de passe) sur l'ancien dump !
Suffit de regarger la fonction "get_user" qui fait un open sur "/afs/epitech.net/site/etc/passwd"
