From f85d56ac053fbb215566f8e03bc55938605fdf49 Mon Sep 17 00:00:00 2001 From: Dom Date: Fri, 10 Apr 2026 09:30:45 +0200 Subject: [PATCH] =?UTF-8?q?feat:=20lea=5Fuia=20=E2=80=94=20helper=20Rust?= =?UTF-8?q?=20Windows=20UI=20Automation=20(cross-compil=C3=A9)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Premier pas de l'Option B hybride : vision + UIA pour Windows natif. Pourquoi Rust ? - Binaire standalone ~500 Ko, aucune dépendance runtime - 5-10x plus rapide que pywinauto (10-20ms par query vs 50-200ms) - Compilation cross-platform depuis Linux (x86_64-pc-windows-gnu) - Safe : pas de crash sur null pointer ou memory leak - Préparation d'un déploiement industriel robuste Commandes : - query --x N --y N : élément UIA à cette position - find --name "..." --control-type "..." : recherche par nom - capture --max-depth N : élément focus + hiérarchie - health : vérifier que UIA est dispo Sortie JSON structurée (stdin/stdout pour IPC avec Python). Stub Linux pour dev/tests sans Windows. Validé sur VM Windows : - query (100,100) → "Bureau 1" en 18ms - query (500,400) → "Bureau 1" en 12ms - find "Rechercher" → not_found en 11ms (normal, rien d'ouvert) Le binaire lea_uia.exe sera
