 # DEVLOG - ComfyUI-Workflow-Studio

+## 2026-03-28: v0.2.2 Modelsタブ・CivitAI連携
+
+### 概要
+- ComfyUIにインストールされたモデル（Checkpoint、LoRA、VAE、ControlNet、UNET、TextEncoder）を一覧・管理する「Models」タブを新規追加

+
+### 新規ファイル

+- `ModelsService`: メタデータのCRUD（お気に入り、タグ、メモ、SHA256）
+- `find_preview_image()`: `{stem}.preview.png`等のプレビュー画像を自動検出
+- `get_model_groups()` / `save_model_groups()`: グループの永続化（`model_metadata.json`の`_groups`キー）
+
+#### `py/services/civitai_service.py` — CivitAI API連携
+- `calculate_sha256()`: モデルファイルのSHA256ハッシュ計算
+- `fetch_by_hash()`: CivitAI APIからモデル情報取得（キャッシュ付き）
+- `batch_fetch()`: 複数モデルの一括取得（プログレスコールバック対応）
+- `_extract_info()`: APIレスポンスから必要フィールドを抽出（modelName, baseModel, trainedWords, images等）
+- キャッシュ: `civitai_cache.json`に保存
+
+#### `py/routes/models_routes.py` — モデル管理APIルート
+- `GET/POST /api/wfm/models/metadata` — メタデータCRUD
+- `GET /api/wfm/models/preview` — プレビュー画像配信

+
+#### `py/wfm.py`
+- `models_routes`のインポートとルート登録追加
+
+#### `templates/index.html`
+- Modelsタブボタン・セクション追加（サブタブナビ、ツールバー、グリッド、サイドパネル）
+- ヘルプタブにModels Tabセクション追加
+
+#### `static/js/app.js`
+- `models-tab.js`のimportと`initModelsTab()`呼び出し追加
+- i18nマッピングにModelsタブ・ヘルプ用キー追加
+
+#### `static/js/nodes-tab.js`
+- カードビュー: パッケージバッジ削除、カード左端にパッケージ色のボーダー追加
+- カードビュー: 入出力カウント表示を削除
+- ページネーションをツールバーに移動
+
+#### `static/js/workflow-tab.js`
+- ページネーションをツールバーに移動

+- ヘルプModelsセクション: `helpModels1`〜`helpModels7`
+- ファイルパス関連: `modelsFilePath`, `modelsCopyPath`, `modelsCopiedPath`
+
+### 技術的な判断
+- **プレビュー画像判定**: HEADリクエストではなく`img.onload/onerror`パターンを採用（404コンソールスパム回避）
+- **CivitAI一括取得**: ブロッキングリクエストではなくSSE（Server-Sent Events）でリアルタイムプログレス表示
+- **aiohttp HEAD自動登録**: `add_get`が自動でHEADも登録するため、明示的なHEADルート追加は不要（重複RuntimeError回避）
+- **テーブルビューメモ列**: `max-width: 200px`＋`text-overflow: ellipsis`で長文を省略表示
+- **ファイルパス表示**: バックエンドAPIでフルパスを解決し、クリックでクリップボードコピー
+
+## 2026-03-27: テーマカスタマイズ機能・設定タブ改善
+
+### 概要
+- テーマのカラーカスタマイズ、背景パターン、フォント選択機能を追加
+- 設定タブの各セクションをアコーディオン式折りたたみに変更
+- ヘルプタブのSettings Tab説明を更新
+
+### 変更内容
+
+#### `static/js/settings-tab.js` — テーマカスタマイズ機能追加
+- **カラーオーバーライド:** 6つのCSS変数（背景、サブ背景、サーフェス、テキスト、プライマリ、アクセント）をカラーピッカーでリアルタイム調整、localStorageに保存
+- **背景パターン:** 7種類（なし、横/縦/斜めストライプ、ポルカドット、チェック、SVGファイル）を選択可能
+  - パターンオプション: 色、不透明度、サイズ、間隔（gap）スライダー
+  - SVGタイリング: FileReader APIでクライアント側読込、色の置換（fill/stroke属性＋`<style>`要素注入）、`::after`疑似要素でopacity制御、gap対応はviewBox拡張ラッパーSVG方式
+- **フォント選択:** 16種のGoogle Fonts（日本語デザインフォント含む）を動的ロード、クリックで即時プレビュー
+  - ゴシック系: Noto Sans JP, Zen丸ゴシック, M PLUS Rounded, 小杉丸ゴシック, さわらびゴシック, BIZ UDPゴシック
+  - デザイン系: ドットゴシック16, はちまるポップ, デラゴシック, レゲエ One, ロックンロール, ステッキ, トレイン One
+  - 等幅: Space Mono, Fira Code
+- **保存ロジック修正:** `saveLocalSettings()`のスプレッドマージでは`delete`したキーが消えない問題を修正、リセット時は`localStorage.setItem()`で直接上書き
+- **SVGリカラー強化:** `<style>`ブロックをSVGに注入し、fill属性がない要素にも色を適用
+
+#### `static/css/main.css` — UIスタイル追加
+- **設定アコーディオン:** `<details>`/`<summary>`要素用のスタイル（`.wfm-settings-section`, `.wfm-settings-summary`）— 三角矢印回転アニメーション付き
+- **テーマカスタマイザー:** カラーピッカーグリッド、パターン選択グリッド（プレビューSVG付き）、パターンオプション行、フォント選択グリッド
+- **パターンプレビュー改善:** SVGプレビューのコントラストを大幅強化（60x60サイズ、太い線、高opacity、青系前景色）
+
+#### `static/js/i18n.js` — 翻訳追加（EN/JA/ZH）
+- テーマカスタマイズ関連: カラー調整、背景パターン、パターンオプション（色、不透明度、サイズ、間隔）、フォント
+- フォント名: 16種のフォントラベル
+- ヘルプSettings項目: helpSettings7, helpSettings8追加
+
+#### `static/js/app.js` — i18nマッピング追加
+- `helpSettings7`, `helpSettings8` のHTML id→i18nキーマッピングを追加
+
+#### `templates/index.html` — ヘルプタブ更新
+- Settings Tabセクション: テーマカスタマイズ機能の説明を追加（項目2）、Eagle連携を項目7に、アコーディオン折りたたみを項目8に追加
+
+### 技術的な判断
+- **SVGカラー変更:** 属性置換だけでは不十分なSVG（CSSクラスやデフォルト黒を使用）に対応するため、`<style>`ブロック注入方式を採用
+- **SVG間隔（gap）:** viewBoxを拡張するラッパーSVGでタイル間に余白を作成
+- **フォント読込:** Google Fonts CDNから動的にlinkタグを挿入、一度読み込んだフォントはSetで管理し重複読込を防止
+- **アコーディオン:** `<details>`/`<summary>`ネイティブHTML要素を使用、JSなしで開閉動作
+
+## 2026-03-26: トップバーボタンアイコン修正・Appモードバッジ調査
+
+### 概要
+- トップバーの3つのボタン（Workflow Studio / Snapshot / Library）のアイコンが表示されない問題を修正
+- ComfyUI Appモード（linearMode）のワークフローJSON構造を調査、バッジ表示対応は保留
+
+### 変更内容
+
+#### `web/comfyui/top_menu_extension.js` — アイコン置換ロジック修正
+- **問題:** `setup()` 内の `replaceButtonIcon()` が `requestAnimationFrame` でボタンを見つけてSVGを注入するが、ComfyUIのVueフレームワークが再レンダリングして元の `<i class="icon-[mdi--...]">` に戻してしまう。リトライ条件が `wfmButtons.length === 0`（ボタン未検出時のみ）のため、一度見つかった後は再注入されなかった
+- **修正:** `MutationObserver` でボタンの親コンテナ（`.actionbar-container`）を監視し、DOMが変更されるたびにSVGアイコンを再注入するように変更
+- `applyButtonIcon()`: ボタンに既にSVGがあればスキップ（無限ループ防止）、なければSVG注入
+- `waitAndObserve()`: ボタンがDOMに現れるまで `requestAnimationFrame` で待機し、見つかったらアイコン置換＋`MutationObserver`監視開始
+
+### Appモードバッジ表示について（保留）
+- ComfyUI Appモード（BETA機能）のワークフローJSON構造を調査
+- `extra.linearMode: true` と `extra.linearData` （inputs/outputs配列）でappモード情報が格納される
+- appモード削除後も `linearData`/`linearMode` キーは残り中身が空配列になるだけ、拡張子 `.app.json` も維持される
+- **結論:** Appモード自体がBETA機能のため、バッジ表示対応は現状維持とする
+
+## 2026-03-25: v0.2.0 プロンプトプリセット機能・Workflow Studio Library
+
+### 概要
+- プロンプトプリセット機能を追加：サイドパネルからドラッグ＆ドロップでWFS_PromptTextカスタムノードを作成
+- Workflow Studio SPAのPromptタブを3カラムレイアウトに刷新（AIアシスタント｜プリセット編集｜プリセットマネージャー）
+- プリセットのバックエンドAPI化（localStorage→サーバーサイド保存）
+- サイドパネル名を「WF & Node Library」→「Workflow Studio Library」に変更
+
+### 変更内容
+
+#### `py/nodes/prompt_text.py` — WFS_PromptTextカスタムノード（新規）

ketle-manandClaude Opus 4.6	4a890d1312	Fix SVG pattern disappearing when gap > 0 for non-standard viewBox SVGs with non-default viewBox (e.g. "0 -960 960 960") lost their content when wrapped in a nested SVG for gap spacing, because the inner SVG did not inherit the original viewBox. Now extracted and preserved. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-27 09:49:15 +09:00

ketle-manandClaude Opus 4.6	29f1ff9f58	Fix topbar button icons not displaying due to Vue re-render The three WFS buttons (Workflow Studio, Snapshot, Library) showed blank icons because Vue re-rendered the DOM after SVG injection, reverting to unsupported icon-[mdi--*] classes. Use MutationObserver to re-apply SVGs whenever the container DOM changes. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-26 00:22:25 +09:00
