From b1efafc4daae386ad1b5e0bc74b3cec8bf9f1276 Mon Sep 17 00:00:00 2001 From: chadgauth Date: Thu, 21 Aug 2025 19:18:09 -0500 Subject: [PATCH] feat: Enhanced diff view system with streaming updates and animations - Add comprehensive diff view coordination system - Implement animated decorations and smart auto-scrolling - Add enhanced streaming content updater for real-time diff visualization - Include diagnostics management and file content handling - Add comprehensive test coverage for new components - Integrate with existing task and extension systems - Improve diff operation handling with better error management --- packages/types/src/vscode.ts | 8 + src/activate/registerCommands.ts | 208 ++++++++ src/core/checkpoints/index.ts | 2 +- src/core/task/Task.ts | 6 +- src/core/task/__tests__/Task.dispose.test.ts | 2 +- src/extension.ts | 3 +- .../editor/DecorationController.ts | 167 +++++- .../editor/DiffViewCoordinator.ts | 377 +++++++++++++ .../editor/EnhancedDiffViewCoordinator.ts | 260 +++++++++ .../editor/__tests__/DiffViewProvider.spec.ts | 9 +- .../components/AnimatedDecorationFactory.ts | 367 +++++++++++++ .../editor/components/AnimationConfig.ts | 399 ++++++++++++++ .../editor/components/DecorationFactory.ts | 183 +++++++ .../editor/components/DiagnosticsManager.ts | 168 ++++++ .../editor/components/DiffOperationHandler.ts | 323 +++++++++++ .../editor/components/DiffViewManager.ts | 241 +++++++++ .../editor/components/DirectFileSaver.ts | 267 ++++++++++ .../components/EnhancedDiffViewManager.ts | 360 +++++++++++++ .../components/EnhancedStreamingUpdater.ts | 503 ++++++++++++++++++ .../editor/components/FileContentManager.ts | 182 +++++++ .../editor/components/SmartAutoScroller.ts | 410 ++++++++++++++ .../components/StreamingContentUpdater.ts | 257 +++++++++ .../__tests__/DiffOperationHandler.test.ts | 219 ++++++++ .../__tests__/FileContentManager.test.ts | 183 +++++++ .../__tests__/StreamingContentUpdater.test.ts | 237 +++++++++ src/package.json | 140 +++++ 26 files changed, 5445 insertions(+), 36 deletions(-) create mode 100644 src/integrations/editor/DiffViewCoordinator.ts create mode 100644 src/integrations/editor/EnhancedDiffViewCoordinator.ts create mode 100644 src/integrations/editor/components/AnimatedDecorationFactory.ts create mode 100644 src/integrations/editor/components/AnimationConfig.ts create mode 100644 src/integrations/editor/components/DecorationFactory.ts create mode 100644 src/integrations/editor/components/DiagnosticsManager.ts create mode 100644 src/integrations/editor/components/DiffOperationHandler.ts create mode 100644 src/integrations/editor/components/DiffViewManager.ts create mode 100644 src/integrations/editor/components/DirectFileSaver.ts create mode 100644 src/integrations/editor/components/EnhancedDiffViewManager.ts create mode 100644 src/integrations/editor/components/EnhancedStreamingUpdater.ts create mode 100644 src/integrations/editor/components/FileContentManager.ts create mode 100644 src/integrations/editor/components/SmartAutoScroller.ts create mode 100644 src/integrations/editor/components/StreamingContentUpdater.ts create mode 100644 src/integrations/editor/components/__tests__/DiffOperationHandler.test.ts create mode 100644 src/integrations/editor/components/__tests__/FileContentManager.test.ts create mode 100644 src/integrations/editor/components/__tests__/StreamingContentUpdater.test.ts diff --git a/packages/types/src/vscode.ts b/packages/types/src/vscode.ts index 00f6bbbcba9..a875a53d248 100644 --- a/packages/types/src/vscode.ts +++ b/packages/types/src/vscode.ts @@ -53,6 +53,14 @@ export const commandIds = [ "focusInput", "acceptInput", "focusPanel", + + "toggleDiffAnimations", + "setDiffAnimationSpeed", + "toggleAutoScroll", + "configureAutoScroll", + "toggleAnimationEffect", + "applyAnimationPreset", + "showAnimationStats", ] as const export type CommandId = (typeof commandIds)[number] diff --git a/src/activate/registerCommands.ts b/src/activate/registerCommands.ts index 0534f247822..1f9a3011187 100644 --- a/src/activate/registerCommands.ts +++ b/src/activate/registerCommands.ts @@ -9,6 +9,7 @@ import { getCommand } from "../utils/commands" import { ClineProvider } from "../core/webview/ClineProvider" import { ContextProxy } from "../core/config/ContextProxy" import { focusPanel } from "../utils/focusPanel" +import { AnimationConfig } from "../integrations/editor/components/AnimationConfig" import { registerHumanRelayCallback, unregisterHumanRelayCallback, handleHumanRelayResponse } from "./humanRelay" import { handleNewTask } from "./handleTask" @@ -221,6 +222,213 @@ const getCommandsMap = ({ context, outputChannel, provider }: RegisterCommandOpt visibleProvider.postMessageToWebview({ type: "acceptInput" }) }, + toggleDiffAnimations: async () => { + try { + const currentSettings = AnimationConfig.getSettings() + AnimationConfig.updateSettings({ enabled: !currentSettings.enabled }) + await AnimationConfig.saveSettings() + + const status = currentSettings.enabled ?
