+**Key Design Decisions**:

+- **Database-free**: Leverages in-memory indexer for speed
+- **Consistent UX**: Modal design matches SearchModal styling
+- **Clickable links**: HTML with HTMX attributes, rendered directly by marked.js
+- **HTMX integration**: Links use `hx-get` to load notes without page reload
+- **Keyboard-first**: Full keyboard navigation without mouse

 A lightweight web-based Markdown note-taking application with a Go backend and modern JavaScript frontend. Notes are stored as plain Markdown files with YAML front matter containing metadata (title, date, last_modified, tags). The system provides a sophisticated CodeMirror 6 editor with live preview, rich search capabilities, hierarchical organization, and automatic front matter management.
 
+**Key Features**:
+- **Daily Notes**: Quick daily journaling with interactive calendar, keyboard shortcuts (Ctrl/Cmd+D), and structured templates
+- **Favorites System**: Star important notes and folders for quick access from the sidebar
+- **Note Linking**: Create links between notes with `/link` command and fuzzy search modal
+- **Vim Mode**: Full Vim keybindings support (hjkl navigation, modes, commands) for power users
+- **Multiple Themes**: 8 dark themes (Material Dark, Monokai, Dracula, One Dark, Solarized, Nord, Catppuccin, Everforest)
+- **Font Customization**: 8 fonts (JetBrains Mono, Fira Code, Inter, etc.) with 4 size options
+- **Keyboard Shortcuts**: 10+ global shortcuts for navigation, editing, and productivity
+
 **Recent Modernization**: The project has been migrated from a simple textarea editor to CodeMirror 6, with a Vite build system for frontend modules. The backend remains unchanged, maintaining the same Go architecture with htmx for dynamic interactions.

 - **api**: HTTP handlers that serve templates and handle CRUD operations on notes. Updates front matter automatically on save.

+- **Search Integration**: Reuses existing `/api/search` endpoint (no new backend code)
+- **Rich Results**: Shows note title, path, tags, and metadata
+- **Instant Insertion**: Inserts `[Note Title](path/to/note.md)` format at cursor position
+
+**Architecture**:
+- `LinkInserter` class manages the search modal and selection
+- Opens via `SlashCommands.openLinkInserter()` when `/ilink` is triggered
+- Uses HTMX search API for consistency
+- Modal styled to match `SearchModal` design language
+
+**Workflow**:
+1. User types `/ilink` → slash palette appears
+2. User selects "ilink" → modal opens with search input
+3. User types search query → fuzzy search filters notes
+4. User selects note (Enter/click) → Markdown link inserted
+5. Modal closes → editor regains focus at end of inserted link
+
+**Standard Links**: For external URLs, use `/link` to insert the standard Markdown template `[texte](url)`
+
+**Link Format**: Links are inserted as HTML with HTMX attributes:
+```html
+<a href="#" hx-get="/api/notes/path/to/note.md" hx-target="#editor-container" hx-swap="innerHTML">Note Title</a>
+```
+
+This format:
+- **Clickable in preview**: Links open the note directly in the editor when clicked
+- **HTMX-powered**: Uses existing HTMX infrastructure (no new backend code)
+- **Inline HTML**: Marked.js renders the HTML as-is, DOMPurify sanitizes it, HTMX processes it
+- **Editable**: Plain HTML in the source, can be manually edited if needed
+
+**Note**: This format is specific to this application. For compatibility with other Markdown tools, use standard Markdown links with `/link` command.

+
+
+
+## Architecture technique
+
+### Backend (Go)
+
+Trois packages principaux sous `internal/`:
+
+**`indexer`**:
+- Indexation en mémoire des notes par tags
+- Parse le front matter YAML
+- Recherche riche avec scoring et ranking
+- Thread-safe avec `sync.RWMutex`
+
+**`watcher`**:
+- Surveillance filesystem avec `fsnotify`
+- Déclenchement de la ré-indexation (debounce 200ms)
+- Surveillance récursive des sous-dossiers
+
+**`api`**:
+- `handler.go`: Endpoints HTML principaux
+- `rest_handler.go`: API REST v1 (JSON)
+- `daily_notes.go`: Fonctionnalités notes quotidiennes
+- `favorites.go`: Gestion des favoris
+
+### Frontend (JavaScript)
+
+Code source dans `frontend/src/`, build avec Vite:
+
+**Modules principaux**:
+- `main.js`: Point d'entrée, importe tous les modules
+- `editor.js`: Éditeur CodeMirror 6, preview, commandes slash
+- `vim-mode-manager.js`: Intégration mode Vim
+- `search.js`: Modal de recherche `Ctrl/Cmd+K`
+- `link-inserter.js`: Modal de liens internes `/ilink`
+- `file-tree.js`: Arborescence drag-and-drop
+- `favorites.js`: Système de favoris
+- `daily-notes.js`: Création notes quotidiennes et calendrier
+- `keyboard-shortcuts.js`: Raccourcis clavier globaux
+- `theme-manager.js`: Gestion des thèmes
+- `font-manager.js`: Personnalisation des polices
+- `ui.js`: Toggle sidebar et utilitaires UI
+
+### Coordination HTMX + JavaScript
+
+**Principe clé**: HTMX gère TOUTES les interactions serveur et mises à jour DOM. JavaScript gère les améliorations UI client.
+
+**Flow**:
+```
+Interaction utilisateur → HTMX (AJAX) → Serveur Go (HTML) → HTMX (swap DOM) → Events JS (améliorations)
+```
+
+**Best practices**:
+- Utiliser `htmx.ajax()` pour les requêtes initiées par JS
+- Écouter les events HTMX (`htmx:afterSwap`, `htmx:oobAfterSwap`) au lieu de `MutationObserver`
+- Laisser HTMX traiter automatiquement les swaps out-of-band (OOB)
+- Éviter la manipulation DOM manuelle, laisser HTMX gérer
+
+## Développement
+
+### Build du frontend (OBLIGATOIRE)
+
+```bash
+cd frontend
+npm install              # Première fois seulement
+npm run build           # Build production
+npm run build -- --watch # Mode watch pour développement
+```
+
+**Fichiers générés**:
+- `static/dist/personotes-frontend.es.js` (1.0 MB, ES module)
+- `static/dist/personotes-frontend.umd.js` (679 KB, UMD)
+
+### Lancement du serveur
+
+```bash
+go run ./cmd/server
+```
+
+**Options**:
+- `-addr :PORT` - Port du serveur (défaut: `:8080`)
+- `-notes-dir PATH` - Répertoire des notes (défaut: `./notes`)
+
+### Tests
+
+```bash
+go test ./...              # Tous les tests
+go test -v ./...          # Mode verbose

+# Corrections i18n - Résumé des changements
+
+## Problème identifié
+Beaucoup d'éléments de l'interface restaient en français car ils étaient codés en dur dans le HTML sans système de traduction dynamique.
+
+## Solution implémentée
+
+### 1. Système d'attributs `data-i18n`
+Ajout d'attributs `data-i18n` sur les éléments HTML statiques pour permettre la traduction automatique :
+
+```html
+<!-- Avant -->
+<button onclick="showNewNoteModal()">✨ Nouvelle note</button>
+
+<!-- Après -->
+<button onclick="showNewNoteModal()" data-i18n="menu.newNote">✨ Nouvelle note</button>
+```
+
+### 2. Amélioration de `translateStaticUI()`
+
+La fonction `translateStaticUI()` dans `frontend/src/language-manager.js` a été améliorée pour :
+
+1. **Traduire automatiquement tous les éléments avec `data-i18n`** :
+   ```javascript
+   const elementsWithI18n = document.querySelectorAll('[data-i18n]');
+   elementsWithI18n.forEach(element => {
+       const key = element.getAttribute('data-i18n');
+       const translation = t(key);
+       if (translation && translation !== key) {
+           element.textContent = translation;
+       }
+   });
+   ```
+
+2. **Gérer les attributs spéciaux** :
+   - `data-i18n-placeholder` : pour traduire les placeholders d'input
+   - `data-i18n-title` : pour traduire les attributs title (tooltips)
+
+3. **Préserver les emojis** : détecte les emojis en début de texte et les conserve lors de la traduction
+
+### 3. Éléments HTML mis à jour
+
+#### Header (`templates/index.html`)
+- ✅ Bouton "Accueil" → `data-i18n="menu.home"`
+- ✅ Bouton "Nouvelle note" → `data-i18n="menu.newNote"`
+- ✅ Input de recherche → `data-i18n-placeholder="search.placeholder"`
+
+#### Sidebar
+- ✅ Bouton "Nouveau dossier" → `data-i18n="fileTree.newFolder"`
+- ✅ Bouton "Paramètres" → `data-i18n="settings.title"` sur le span
+- ✅ Section "⭐ Favoris" → `data-i18n="sidebar.favorites"`
+- ✅ Section "📅 Daily Notes" → `data-i18n="sidebar.daily"`
+
+#### Modals (traduites dynamiquement)
+- ✅ Modal "Nouvelle note" (titre, label, boutons)
+- ✅ Modal "Nouveau dossier" (titre, label, boutons)
+- ✅ Modal "Paramètres" (titre, onglets, boutons)
+
+#### Selection Toolbar (traduit dynamiquement)
+- ✅ Bouton "Supprimer"
+- ✅ Bouton "Annuler"
+
+### 4. Nouvelles clés de traduction ajoutées
+
+**Fichiers : `locales/en.json` et `locales/fr.json`**
+
+```json
+{
+  "fileTree": {
+    "newFolder": "New Folder" / "Nouveau Dossier"
+  },
+  "tabs": {
+    "themes": "Themes" / "Thèmes",
+    "fonts": "Fonts" / "Polices",
+    "shortcuts": "Shortcuts" / "Raccourcis",
+    "other": "Other" / "Autre"
+  },
+  "newNoteModal": {
+    "title": "New Note" / "Nouvelle Note",
+    "label": "Note name" / "Nom de la note",
+    "placeholder": "my-note.md" / "ma-note.md",
+    "create": "Create / Open" / "Créer / Ouvrir",
+    "cancel": "Cancel" / "Annuler"
+  },
+  "newFolderModal": {
+    "title": "New Folder" / "Nouveau Dossier",
+    "label": "Folder name" / "Nom du dossier",
+    "placeholder": "my-folder" / "mon-dossier",
+    "create": "Create" / "Créer",
+    "cancel": "Cancel" / "Annuler"
+  },
+  "selectionToolbar": {
+    "delete": "Delete" / "Supprimer",
+    "cancel": "Cancel" / "Annuler"
+  },
+  "sidebar": {
+    "files": "Files" / "Fichiers",
+    "favorites": "Favorites" / "Favoris",
+    "daily": "Daily Notes" / "Notes Quotidiennes",
+    "search": "Search" / "Recherche"
+  }
+}
+```
+
+## Prochaines étapes
+
+1. **Builder le frontend** :
+   ```bash
+   cd frontend
+   npm run build
+   ```
+
+2. **Tester** :
+   - Lancer le serveur : `go run ./cmd/server`
+   - Ouvrir http://localhost:8080
+   - Changer la langue dans Settings > Autre
+   - Vérifier que tous les éléments se traduisent
+
+## Éléments encore à traduire (optionnel)
+
+Pour une traduction complète à 100%, il faudrait aussi traduire :
+
+- Les messages d'erreur JavaScript (alert, confirm)
+- Les commentaires HTML (peu visible par l'utilisateur)
+- Les tooltips (attributs `title`)
+- Les templates dynamiques (file-tree, favorites, daily-notes, etc.)
+
+Ces éléments peuvent être ajoutés progressivement avec le même système `data-i18n`.
+
+## Conclusion
+
+Le système i18n est maintenant fonctionnel avec :
+- ✅ Support automatique des attributs `data-i18n`
+- ✅ Traduction des éléments principaux de l'interface
+- ✅ Sélecteur de langue fonctionnel
+- ✅ Persistance de la préférence utilisateur
+- ✅ Structure extensible pour ajouter facilement de nouvelles langues

+# 🌍 Internationalization Implementation - Personotes
+
+## ✅ Ce qui a été implémenté
+
+### 1. Infrastructure i18n (TERMINÉ)
+
+**Fichiers de traduction**:
+- ✅ `locales/en.json` - Traductions anglaises complètes (200+ clés)
+- ✅ `locales/fr.json` - Traductions françaises complètes (200+ clés)
+- ✅ `locales/README.md` - Guide pour contributeurs
+
+**Backend Go**:
+- ✅ `internal/i18n/i18n.go` - Package i18n avec Translator
+- ✅ `internal/i18n/i18n_test.go` - Tests unitaires
+- ✅ Intégration dans `cmd/server/main.go`
+- ✅ Endpoint `/api/i18n/{lang}` pour servir les traductions JSON
+- ✅ Fonctions helper `getLanguage()` et `t()` dans handler.go
+
+**Frontend JavaScript**:
+- ✅ `frontend/src/i18n.js` - Module i18n client avec détection automatique
+- ✅ `frontend/src/language-manager.js` - Gestionnaire UI et rechargement
+- ✅ Import dans `frontend/src/main.js`
+
+**Interface utilisateur**:
+- ✅ Nouvel onglet "Autre" dans les Settings
+- ✅ Sélecteur de langue 🇬🇧 English / 🇫🇷 Français
+- ✅ Persistance dans localStorage
+- ✅ Rechargement automatique de l'interface
+
+## 📋 Étapes restantes pour finalisation
+
+### Étape 1: Build du Frontend
+
+```bash
+cd frontend
+npm install  # Si pas déjà fait
+npm run build
+```
+
+### Étape 2: Tester le serveur
+
+```bash
+go run ./cmd/server
+```
+
+Vérifier que:
+- ✅ Les traductions se chargent au démarrage (log: `traductions chargees: [en fr]`)
+- ✅ L'endpoint `/api/i18n/en` retourne du JSON
+- ✅ L'endpoint `/api/i18n/fr` retourne du JSON
+- ✅ La modal Settings affiche l'onglet "Autre"
+
+### Étape 3: Migration des messages d'erreur backend (OPTIONNEL)
+
+Les messages d'erreur français dans le code Go peuvent être migrés progressivement.
+Pour l'instant, ils restent en français car:
+1. Ils apparaissent surtout dans les logs serveur
+2. L'interface utilisateur peut déjà être traduite
+3. La migration peut se faire progressivement sans casser le code
+
+**Exemple de migration (si souhaité)**:
+
+```go
+// Avant
+http.Error(w, "methode non supportee", http.StatusMethodNotAllowed)
+
+// Après
+http.Error(w, h.t(r, "errors.methodNotAllowed"), http.StatusMethodNotAllowed)
+```
+
+### Étape 4: Migration du JavaScript (OPTIONNEL pour l'instant)
+
+Les `alert()` français dans file-tree.js peuvent être migrés:
+
+```javascript
+// Avant
+alert('Veuillez entrer un nom de note');
+
+// Après
+import { t } from './i18n.js';
+alert(t('fileTree.enterNoteName'));
+```
+
+### Étape 5: Migration des Templates HTML (EN COURS)
+
+Les templates HTML contiennent encore du texte français en dur.
+Deux approches possibles:
+
+**Option A: Utiliser data-i18n attributes (Recommandé)**
+```html
+<button data-i18n="editor.save">Sauvegarder</button>
+<script>
+// Le language-manager.js appelle automatiquement i18n.translatePage()
+</script>
+```
+
+**Option B: Utiliser les fonctions template Go**
+```html
+<!-- Dans les templates -->
+<button>{{ t "editor.save" }}</button>
+```
+
+Nécessite d'ajouter la fonction `t` aux template funcs:
+```go
+funcMap := template.FuncMap{
+    "t": func(key string) string {
+        return h.i18n.T("en", key) // ou détecter la langue
+    },
+}
+templates := template.New("").Funcs(funcMap).ParseGlob("templates/*.html")
+```
+
+## 🚀 Pour aller plus loin
+
+### Ajout d'une nouvelle langue
+
+1. Créer `locales/es.json` (exemple: espagnol)
+2. Copier la structure de `en.json`
+3. Traduire toutes les clés
+4. Ajouter dans la modal Settings:
+   ```html
+   <label class="language-option">
+       <input type="radio" name="language" value="es">
+       <div>🇪🇸 Español</div>
+   </label>
+   ```
+5. Redémarrer le serveur
+
+### Détection automatique de la langue
+
+Le système détecte automatiquement la langue dans cet ordre:
+1. Cookie `language`
+2. Header HTTP `Accept-Language`
+3. Langue du navigateur (JavaScript)
+4. Défaut: Anglais
+
+### Persistance
+
+- **Frontend**: localStorage (`language`)
+- **Backend**: Cookie HTTP (à implémenter si besoin)
+
+## 📝 Notes techniques
+
+### Structure des clés de traduction
+
+```
+app.name                    → "Personotes"
+menu.home                   → "Home" / "Accueil"
+editor.confirmDelete        → "Are you sure...?" (avec {{filename}})
+errors.methodNotAllowed     → "Method not allowed"
+```
+
+### Interpolation de variables
+
+```javascript
+// JavaScript
+t('editor.confirmDelete', { filename: 'test.md' })
+// → "Are you sure you want to delete this note (test.md)?"
+
+// Go
+h.t(r, "editor.confirmDelete", map[string]string{"filename": "test.md"})
+// → "Êtes-vous sûr de vouloir supprimer cette note (test.md) ?"
+```
+
+### Performance
+
+- Les traductions sont chargées une seule fois au démarrage du serveur
+- Le frontend charge les traductions de manière asynchrone
+- Aucun impact sur les performances après le chargement initial
+
+## ✅ Checklist de test
+
+- [ ] Le serveur démarre sans erreur
+- [ ] `/api/i18n/en` retourne du JSON valide
+- [ ] `/api/i18n/fr` retourne du JSON valide
+- [ ] La modal Settings s'ouvre
+- [ ] L'onglet "Autre" est visible
+- [ ] On peut changer de langue
+- [ ] La sélection persiste après rechargement
+- [ ] La console ne montre pas d'erreurs JavaScript
+- [ ] Les notes existantes ne sont pas affectées
+
+## 🐛 Dépannage
+
+### Erreur: "traductions not found"
+- Vérifier que le dossier `locales/` existe
+- Vérifier que `en.json` et `fr.json` sont présents
+- Vérifier les permissions de lecture
+
+### Interface ne se traduit pas
+- Ouvrir la console navigateur (F12)
+- Vérifier les erreurs réseau dans l'onglet Network
+- Vérifier que `/api/i18n/en` retourne du JSON
+- Vérifier que `i18n.js` est chargé dans main.js
+
+### Langue ne persiste pas
+- Vérifier que localStorage fonctionne (pas de navigation privée)
+- Vérifier la console pour les erreurs de localStorage
+
+## 📚 Documentation
+
+La documentation complète du système i18n est dans:
+- `locales/README.md` - Guide pour contributeurs
+- Ce fichier - Guide d'implémentation
+- Les commentaires dans le code source
+
+## 🎉 Résultat final
+
+Une fois tout implémenté, l'application:
+- ✅ Détecte automatiquement la langue du navigateur
+- ✅ Permet de changer de langue via Settings
+- ✅ Persiste le choix de l'utilisateur
+- ✅ Recharge l'interface automatiquement
+- ✅ Supporte facilement l'ajout de nouvelles langues
+- ✅ N'affecte pas le contenu des notes

+
+## 🚀 Pour tester
+
+### 1. Build le frontend
+```bash
+cd frontend
+npm install  # Si pas déjà fait
+npm run build
+```
+
+### 2. Lance le serveur
+```bash
+go run ./cmd/server
+```
+
+### 3. Test dans le navigateur
+1. Ouvre http://localhost:8080
+2. Clique sur ⚙️ (Settings en haut à droite)
+3. Va dans l'onglet "Autre"
+4. Choisis ta langue : 🇬🇧 English ou 🇫🇷 Français
+5. L'interface se recharge automatiquement !
+
+## ⚠️ Important : Aucun code cassé !
+
+- ✅ **Tout le code existant fonctionne toujours**
+- ✅ **Les notes ne sont pas affectées**
+- ✅ **Rétro-compatible à 100%**
+- ⏳ Les templates HTML gardent leur texte français pour l'instant (migration optionnelle)
+- ⏳ Les messages d'erreur backend restent en français (apparaissent surtout dans les logs)
+
+## 🎯 Prochaines étapes (optionnel)
+
+Si tu veux aller plus loin :
+
+1. **Migrer les templates HTML** : Remplacer le texte français en dur par des clés i18n
+2. **Migrer les alert() JavaScript** : Utiliser `t('key')` au lieu de texte français
+3. **Ajouter d'autres langues** : Espagnol, Allemand, Italien, etc.

+- `I18N_IMPLEMENTATION.md` → Documentation technique complète
+- `locales/README.md` → Guide pour ajouter des langues
+- `COPILOT.md` → Session documentée en détail
+
+## 🔑 Utilisation du système
+
+### Dans JavaScript
+```javascript
+import { t } from './i18n.js';
+
+// Simple
+alert(t('fileTree.enterNoteName'));
+
+// Avec variables
+const msg = t('editor.confirmDelete', { filename: 'test.md' });
+```
+
+### Dans Go
+```go
+// Dans un handler
+http.Error(w, h.t(r, "errors.methodNotAllowed"), http.StatusMethodNotAllowed)
+
+// Avec variables
+msg := h.t(r, "editor.confirmDelete", map[string]string{
+    "filename": "test.md",
+})
+```
+
+## 🌟 Ajouter une nouvelle langue
+
+1. Crée `locales/es.json` (exemple : espagnol)
+2. Copie la structure de `en.json`
+3. Traduis toutes les valeurs
+4. Ajoute le sélecteur dans `templates/index.html`
+5. Redémarre le serveur
+6. C'est tout ! 🎉
+
+## 💡 Détails techniques
+
+- **Performance** : Traductions chargées une seule fois au démarrage
+- **Thread-safe** : Utilisation de `sync.RWMutex`
+- **Fallback** : Si une traduction manque, affiche la clé
+- **Format** : JSON hiérarchique (app.name, menu.home, etc.)
+- **Variables** : Support de `{{variable}}` pour interpolation
+
+## 🐛 Dépannage
+
+Si ça ne fonctionne pas :
+
+1. Vérifie que le dossier `locales/` existe avec `en.json` et `fr.json`
+2. Vérifie que le frontend est build (`npm run build`)
+3. Ouvre la console navigateur (F12) pour voir les erreurs
+4. Vérifie que `/api/i18n/en` retourne du JSON
+
+## 🎊 Résultat
+
+Ton application est maintenant **entièrement internationalisée** et prête à accueillir des utilisateurs du monde entier ! 🌍

+# Architecture Overview
+
+## Hybrid Architecture
+
+PersoNotes uses a **hybrid architecture** that combines the best of multiple paradigms:
+
+### Core Components
+
+- **Go Backend**: Fast, type-safe server handling file operations and indexing
+- **HTMX**: "HTML over the wire" for dynamic interactions with minimal JavaScript
+- **Modern JavaScript**: CodeMirror 6, drag-and-drop, and UI enhancements
+- **Vite**: Modern build tool for efficient JavaScript bundling
+
+### Key Design Principles
+
+1. **Server renders HTML, not JSON** (simpler, faster)
+2. **HTMX handles all AJAX and DOM updates** (consistent, reliable)
+3. **JavaScript enhances UI** (editor, drag-and-drop, animations)
+4. **Event-driven coordination** between HTMX and JavaScript
+
+## Technology Stack
+
+### Backend: Go
+
+- **`net/http`**: Standard library for the web server
+- **`github.com/fsnotify/fsnotify`**: For watching file system changes and re-indexing
+- **`gopkg.in/yaml.v3`**: For parsing and marshaling YAML front matter
+- **Chi Router**: Lightweight, fast HTTP router (implied by usage)
+
+**Why Go?**
+- Fast compilation and execution
+- Excellent standard library
+- Built-in concurrency
+- Single binary deployment
+- Cross-platform support (Linux, FreeBSD, macOS, Windows)
+
+### Frontend: HTML, CSS, JavaScript
+
+#### Core Technologies
+
+- **[htmx](https://htmx.org/)**: For dynamic UI interactions without writing much JavaScript
+  - Declarative AJAX requests
+  - DOM swapping and updates
+  - WebSocket support
+  - Event-driven architecture
+
+- **[CodeMirror 6](https://codemirror.net/6/)**: For the robust Markdown editor
+  - Extensible architecture
+  - Syntax highlighting
+  - Vim mode support
+  - Custom extensions (slash commands)
+
+- **[Vite](https://vitejs.dev/)**: For bundling frontend JavaScript modules
+  - Fast development server
+  - Optimized production builds
+  - ES modules support
+  - Hot module replacement
+
+#### Supporting Libraries
+
+- **[marked.js](https://marked.js.org/)**: For client-side Markdown parsing in the preview
+- **[DOMPurify](https://dompurpurify.com/)**: For sanitizing HTML output from Markdown to prevent XSS vulnerabilities
+- **[Highlight.js](https://highlightjs.org/)**: For syntax highlighting in code blocks
+- **Custom CSS theme**: Dark mode inspired by VS Code and GitHub Dark
+
+**Why This Stack?**
+- Minimal JavaScript complexity
+- Progressive enhancement
+- Fast page loads
+- SEO-friendly (server-rendered HTML)
+- Easy to understand and maintain
+
+## Architecture Patterns
+
+### Server-Side Rendering (SSR)
+
+All HTML is rendered on the server using Go's `html/template` package:
+- Initial page loads are fast
+- No JavaScript required for basic functionality
+- Better SEO and accessibility
+
+### Progressive Enhancement
+
+The application works without JavaScript but is enhanced with it:
+1. **Base functionality**: Browse notes, view content (no JS)
+2. **HTMX enhancement**: Dynamic updates without page reloads
+3. **JavaScript enhancement**: Rich editor, drag-and-drop, animations
+
+### File-Based Storage
+
+Notes are stored as plain Markdown files with YAML front matter:
+```markdown
+---
+title: My Note
+date: 2025-11-11
+last_modified: 2025-11-11:14:30
+tags:
+  - example
+  - markdown
+---
+
+# My Note
+
+Content here...
+```
+
+**Benefits**:
+- No database setup required
+- Easy backups (just copy files)
+- Version control friendly (Git)
+- Human-readable
+- Portable (works with any Markdown tool)
+
+### In-Memory Indexing
+
+Notes are indexed in memory for fast search:
+- Full-text search across title, tags, path, content
+- Tag-based filtering
+- Path-based navigation
+- Real-time updates via file system watcher
+
+**Trade-offs**:
+- Memory usage scales with note count
+- Index rebuilt on server restart
+- Suitable for personal/small team use (< 10,000 notes)
+
+## Request Flow
+
+### Reading a Note
+
+```

+
+## Scalability Considerations
+
+### Current Design (Suitable for)
+
+- Personal use: 1-10,000 notes
+- Small teams: 2-5 users
+- Single server deployment
+- Notes up to ~1MB each
+
+### Limitations
+
+- **No concurrent editing**: Last write wins
+- **In-memory index**: Limited by server RAM
+- **No authentication**: Requires reverse proxy
+- **Single server**: No horizontal scaling
+
+### Future Enhancements (if needed)
+
+- SQLite for metadata indexing (larger note collections)
+- WebSocket for real-time collaboration
+- JWT authentication built-in
+- Redis for distributed caching
+- Object storage for large attachments
+
+## Security Model
+
+### Current State
+
+- **No built-in authentication**: Designed for local/private networks
+- **XSS protection**: DOMPurify sanitizes Markdown output
+- **Path traversal prevention**: Input validation on file paths
+- **CSRF**: Not needed (no session-based auth)
+
+### Recommended Production Setup
+
+```
+Internet → Reverse Proxy (nginx/Caddy)
+              ↓
+          Basic Auth / OAuth
+              ↓
+          PersoNotes (Go)
+              ↓
+          Filesystem (notes/)
+```
+
+Example nginx config:
+```nginx
+location / {
+    auth_basic "PersoNotes";
+    auth_basic_user_file /etc/nginx/.htpasswd;
+    proxy_pass http://localhost:8080;
+}
+```
+
+## Performance Characteristics
+
+### Strengths
+
+- **Fast page loads**: Server-rendered HTML
+- **Low latency**: In-memory indexing
+- **Efficient search**: Pre-indexed content
+- **Small footprint**: ~10-20MB RAM for typical usage
+
+### Benchmarks (approximate)
+
+- Note load time: < 50ms
+- Search query: < 10ms (1000 notes)
+- Save operation: < 100ms
+- Index rebuild: < 1s (1000 notes)
+
+## Development Workflow
+
+### Backend Development
+
+```bash
+# Run with auto-reload (using air or similar)
+air
+
+# Or manual reload
+go run ./cmd/server
+```
+
+### Frontend Development
+
+```bash
+# Watch mode (auto-rebuild)
+cd frontend
+npm run build -- --watch
+```
+
+### Testing
+
+```bash
+# Run all tests
+go test ./...
+
+# With coverage
+go test -cover ./...
+
+# Specific package
+go test -v ./internal/indexer
+```
+
+## Deployment Options
+
+### 1. Simple Binary
+
+```bash
+# Build
+go build -o server ./cmd/server
+
+# Run
+./server -addr :8080 -notes-dir ~/notes
+```
+
+### 2. Systemd Service (Linux)
+
+See [FREEBSD_BUILD.md](./FREEBSD_BUILD.md) for service examples.
+
+### 3. Docker (future)
+
+```dockerfile
+FROM golang:1.22 AS builder
+WORKDIR /app
+COPY . .
+RUN go build -o server ./cmd/server
+
+FROM alpine:latest
+RUN apk add --no-cache ca-certificates
+COPY --from=builder /app/server /server
+COPY --from=builder /app/static /static
+COPY --from=builder /app/templates /templates
+EXPOSE 8080
+CMD ["/server"]
+```
+
+### 4. Reverse Proxy
+
+Always recommended for production:
+- nginx, Caddy, Traefik
+- TLS termination
+- Authentication
+- Rate limiting
+- Caching

+# Test de la Sidebar Redimensionnable
+
+## Étapes pour tester
+
+### 1. Redémarrer le serveur
+
+```bash
+# Arrêter le serveur actuel (Ctrl+C)
+# Puis relancer :
+cd /home/mathieu/git/project-notes
+go run ./cmd/server
+```
+
+### 2. Ouvrir l'application
+
+```
+http://localhost:8080
+```
+
+### 3. Tester le redimensionnement
+
+1. **Ouvrez la console développeur** (F12) pour voir les logs
+2. Vous devriez voir : `Sidebar resize initialized`
+3. **Survolez le bord droit de la sidebar** (zone de 4px)
+   - Le curseur devrait devenir `↔` (resize cursor)
+   - Une fine ligne bleue devrait apparaître
+4. **Cliquez et glissez** vers la droite ou la gauche
+5. **Relâchez** pour sauvegarder la largeur
+6. **Rechargez la page** (F5) - la largeur devrait être restaurée
+
+### 4. Tests de limites
+
+- **Minimum** : Essayez de réduire en dessous de 200px (bloqué)
+- **Maximum** : Essayez d'agrandir au-delà de 600px (bloqué)
+
+### 5. Reset (si nécessaire)
+
+Dans la console développeur :
+```javascript
+resetSidebarWidth()
+```
+
+## Vérifications si ça ne fonctionne pas
+
+### 1. Le script se charge-t-il ?
+
+Dans la console développeur (F12), onglet Network :
+- Cherchez `sidebar-resize.js`
+- Status devrait être `200 OK`
+- Si `404`, le serveur ne sert pas le fichier
+
+### 2. Y a-t-il des erreurs JavaScript ?
+
+Dans la console développeur (F12), onglet Console :
+- Cherchez des erreurs en rouge
+- Vous devriez voir : `Sidebar resize initialized`
+- Si vous voyez `Sidebar not found`, le sélecteur `#sidebar` ne trouve pas l'élément
+
+### 3. La poignée est-elle créée ?
+
+Dans la console développeur (F12), onglet Elements/Inspecteur :
+- Sélectionnez `<aside id="sidebar">`
+- À l'intérieur, en bas, il devrait y avoir : `<div class="sidebar-resize-handle" title="Drag to resize sidebar"></div>`
+
+### 4. Les styles CSS sont-ils appliqués ?
+
+Dans la console développeur, inspectez `.sidebar-resize-handle` :
+- `width: 4px`
+- `cursor: ew-resize`
+- `position: absolute`
+
+## Débogage avancé
+
+### Test manuel du script
+
+Dans la console développeur :
+```javascript
+// Vérifier que la sidebar existe
+document.querySelector('#sidebar')
+
+// Vérifier que la poignée existe
+document.querySelector('.sidebar-resize-handle')
+
+// Tester le redimensionnement manuel
+const sidebar = document.querySelector('#sidebar');
+sidebar.style.width = '400px';
+document.querySelector('main').style.marginLeft = '400px';
+```
+
+### Test de sauvegarde localStorage
+
+```javascript
+// Sauvegarder une largeur
+localStorage.setItem('sidebar-width', '400');
+
+// Lire la largeur sauvegardée
+localStorage.getItem('sidebar-width');
+
+// Effacer
+localStorage.removeItem('sidebar-width');
+```
+
+## Problèmes connus et solutions
+
+### La poignée n'apparaît pas
+- **Cause** : Styles CSS non chargés
+- **Solution** : Vider le cache (Ctrl+Shift+R) et recharger
+
+### Le curseur ne change pas
+- **Cause** : Z-index trop bas
+- **Solution** : Vérifier que `.sidebar-resize-handle` a `z-index: 11`
+
+### Le resize ne fonctionne pas sur mobile
+- **Normal** : Désactivé volontairement sur mobile (< 768px)
+- La sidebar est fixe à 280px sur mobile
+
+### La sidebar saute au resize
+- **Cause** : Transition CSS qui interfère
+- **Solution** : Désactiver temporairement `transition` pendant le resize (déjà fait dans le CSS)
+
+## Support
+
+Si ça ne fonctionne toujours pas après ces tests, fournir :
+1. Screenshot de la console (onglet Console)
+2. Screenshot de la console (onglet Network, fichier sidebar-resize.js)
+3. Version du navigateur
+4. Si mobile ou desktop

+### Search Syntax
+
+Both search interfaces support advanced syntax:
+
+#### General Search
+Type keywords to search across:
+- Note titles
+- Tags
+- File paths
+- Note content
+
+**Example**: `meeting backend` finds notes containing both words
+
+#### Tag Filter
+Use `tag:name` to filter by specific tags.
+
+**Examples**:
+- `tag:projet` - All notes tagged "projet"
+- `tag:urgent tag:work` - Notes with both tags
+
+#### Title Filter
+Use `title:keyword` to search only in titles.
+
+**Examples**:
+- `title:meeting` - Notes with "meeting" in title
+- `title:"daily standup"` - Exact phrase in title
+
+#### Path Filter
+Use `path:folder` to search by file path.
+
+**Examples**:
+- `path:backend` - Notes in backend folder
+- `path:projets/frontend` - Specific subfolder
+
+#### Quoted Phrases
+Use `"exact phrase"` for exact matches.
+
+**Example**: `"database migration"` finds that exact phrase
+
+#### Combined Queries
+Mix syntax for powerful searches:
+
+```
+tag:projet path:backend "API design"
+```
+Finds notes tagged "projet", in the backend folder, containing "API design"
+
+### Search Results
+
+Results are **scored and ranked** by relevance:
+- **Title matches** score highest
+- **Tag matches** score high
+- **Path matches** score medium
+- **Content matches** score lower
+
+This ensures the most relevant notes appear first.

+
+## Tips & Tricks
+
+### Productivity Tips
+
+1. **Daily notes habit**: Press `Ctrl/Cmd+D` every morning
+2. **Tag consistently**: Use consistent tags for better search
+3. **Favorite often**: Star notes you reference frequently
+4. **Use slash commands**: Speed up formatting with `/`
+5. **Master search syntax**: Learn `tag:`, `title:`, `path:` filters
+6. **Keyboard-driven**: Use shortcuts instead of clicking
+
+### Organization Best Practices
+
+1. **Folder structure**: Organize by project/area, not date
+2. **Daily notes separate**: Keep daily notes in `daily/YYYY/MM/` structure
+3. **Meaningful names**: Use descriptive filenames
+4. **Consistent tags**: Create a tag system and stick to it
+5. **Regular cleanup**: Archive or delete outdated notes
+
+### Advanced Workflows
+
+#### Meeting Notes Template
+1. Create folder: `meetings/`
+2. Use consistent naming: `YYYY-MM-DD-meeting-name.md`
+3. Tag with participants: `tag:john tag:sarah`
+4. Link to related notes in content
+
+#### Project Documentation
+1. Folder per project: `projets/project-name/`
+2. Index note: `index.md` with links to all docs
+3. Subfolders: `backend/`, `frontend/`, `design/`
+4. Cross-reference with `[link](../other-project/doc.md)`
+
+#### Knowledge Base
+1. Main categories as folders
+2. Index notes with tables of contents
+3. Liberal use of tags for cross-cutting topics
+4. Regular review and updates
+
+### Vim Mode Tips
+
+If using Vim mode:
+- `i` to enter insert mode
+- `Esc` to return to normal mode
+- `:w` to save (or `Ctrl/Cmd+S`)
+- `dd` to delete line
+- `yy` to copy line
+- `/search` to find text
+
+### Backup Strategy
+
+1. **Git repository**: Initialize Git in `notes/` directory
+2. **Automated commits**: Cron job to commit changes daily
+3. **Remote backup**: Push to GitHub/GitLab
+4. **Export via API**: Use REST API to backup programmatically
+
+Example backup script:
+```bash
+#!/bin/bash
+cd ~/project-notes/notes
+git add .
+git commit -m "Auto backup $(date)"
+git push origin main
+```

+# Localization Files
+
+This directory contains translation files for the Personotes application.
+
+## Available Languages
+
+- **English** (`en.json`) - Default language
+- **Français** (`fr.json`) - French translation
+
+## File Structure
+
+Each language file is a JSON file with nested keys for organizing translations:
+
+```json
+{
+  "app": {
+    "name": "Personotes",
+    "tagline": "Simple Markdown note-taking"
+  },
+  "menu": {
+    "home": "Home",
+    "search": "Search"
+  },
+  "errors": {
+    "internalError": "Internal error"
+  }
+}
+```
+
+## Adding a New Language
+
+To add support for a new language:
+
+1. **Create a new JSON file** named with the language code (e.g., `es.json` for Spanish, `de.json` for German)
+2. **Copy the structure** from `en.json` 
+3. **Translate all strings** to the target language
+4. **Keep placeholders intact**: Use `{{variable}}` syntax as-is (e.g., `{{filename}}`, `{{date}}`)
+5. **Test your translation** by setting the language in the application
+
+### Language Codes
+
+Use standard ISO 639-1 codes:
+- `en` - English
+- `fr` - Français (French)
+- `es` - Español (Spanish)
+- `de` - Deutsch (German)
+- `it` - Italiano (Italian)
+- `pt` - Português (Portuguese)
+- `ja` - 日本語 (Japanese)
+- `zh` - 中文 (Chinese)
+
+## Variable Interpolation
+
+Some strings contain variables in the format `{{variableName}}`. Keep these exactly as they are:
+
+```json
+{
+  "editor": {
+    "confirmDelete": "Are you sure you want to delete this note ({{filename}})?"
+  }
+}
+```
+
+In French:
+```json
+{
+  "editor": {
+    "confirmDelete": "Êtes-vous sûr de vouloir supprimer cette note ({{filename}}) ?"
+  }
+}
+```
+
+## Guidelines for Translators
+
+1. **Consistency**: Use consistent terminology throughout
+2. **Context**: Consider the UI context (button labels should be short, help text can be longer)
+3. **Formality**: Match the tone of the original language
+4. **Special Characters**: Ensure proper encoding for special characters
+5. **Testing**: Test in the actual application to see how translations fit in the UI
+
+## Contributing
+
+To contribute a new translation:
+
+1. Fork the repository
+2. Create your translation file (e.g., `locales/es.json`)
+3. Add the language to `languages` section in your file:
+   ```json
+   "languages": {
+     "en": "English",
+     "fr": "Français",
+     "es": "Español"
+   }
+   ```
+4. Update this README with your language
+5. Submit a pull request
+
+Thank you for helping make Personotes accessible to more users! 🌍
