 # Changelog
 
+## 2025-12-31 - 3.22.0 - feat(workspace)
+add resizable markdown editor/preview split with draggable handle and markdown outlet styling/demo
+
+- Introduce a flexible split layout for the workspace markdown editor with a draggable resize handle (splitRatio, minPanelSize, dragging state, mouse handlers and cleanup).
+- Enhance dees-workspace-markdown: switch from grid to flex, add resize handle UI, prevent pointer selection while dragging, notify Monaco on resize.
+- Add comprehensive styling and demo content for dees-workspace-markdownoutlet (dark/light themed markdown styles, syntax highlighting classes, and demo scenarios).
+- Fix typescript-intellisense monaco model update: only set model value when content actually changed to avoid cursor resets.
+- Add markdown outlet demo helper and numerous screenshot/image assets (.playwright-mcp) for demos/documentation.
+
+## 2025-12-31 - 3.21.0 - feat(terminal)
+add dynamic bright/dark theming for terminal components and terminal preview
+
+- Add bright/dark theme PNG assets under .playwright-mcp for previews.
+- Replace hardcoded terminal background/colors with cssManager.bdTheme in workspace terminal and preview styles.
+- Introduce getTerminalTheme helper to compute xterm theme for bright/dark modes.
+- Subscribe to themeManager.themeObservable and apply updates to xterm (terminal.options.theme) so terminals update live on theme change.
+- Remove hardcoded background property/CSS var and unused background accessor from workspace terminal.
+- Ensure proper cleanup: unsubscribe theme subscriptions and dispose terminals in disconnectedCallback.
+
+## 2025-12-31 - 3.20.1 - fix(dees-workspace)
+fix demo wrapper and workspace layout; always render terminal preview
+
+- Import @design.estate/dees-wcctools/demotools and wrap demo content in <dees-demowrapper>
+- Create an absolute-positioned container so the dees-workspace fills 100% height/width
+- Always render dees-workspace-terminal-preview (use empty command when none) to avoid conditional rendering issues
+- Set a fixed height (200px) for the terminal preview in the initializing state
+- Add Playwright demo asset .playwright-mcp/dees-workspace-demo-4k.png
+
+## 2025-12-31 - 3.20.0 - feat(workspace)
+rename editor components to workspace group and move terminal & TypeScript intellisense into workspace
+
+- Renamed components and modules from 00group-editor/dees-editor-* to 00group-workspace/dees-workspace-* (e.g. dees-editor-monaco -> dees-workspace-monaco).
+- Moved terminal implementation from dees-terminal to dees-workspace-terminal and updated related imports/usages.
+- Moved TypeScript intellisense manager into 00group-workspace and updated paths.
+- Updated ts_web elements index to export 00group-workspace instead of 00group-editor and adjusted internal imports accordingly.
+- Updated scripts/update-monaco-version.cjs to write MONACO_VERSION into the new workspace path and updated log tags.
+
+## 2025-12-31 - 3.19.1 - fix(intellisense)
+Debounce TypeScript/JavaScript IntelliSense processing and cache missing packages to reduce work and noisy logs
+
+- Add 500ms debounce in editor workspace to avoid parsing on every keystroke
+- Introduce notFoundPackages cache to skip repeated filesystem checks for packages without types
+- Clear not-found cache when scanning node_modules so newly installed packages are re-detected
+- Remove noisy console logs and make file/directory read errors non-fatal (ignored)
+- Simplify processContentChange signature (removed optional filePath) and remove manual diagnostic refresh logic
+
+## 2025-12-31 - 3.19.0 - feat(dees-editor-workspace)
+improve TypeScript IntelliSense, auto-run workspace init commands, and watch node_modules for new packages
+
+- Execute an onInit command from /npmextra.json on workspace initialization (e.g., run pnpm install).
+- Add npmextra.json and an import test file (importtest.ts) plus a sample dependency in the scaffold to test package imports.
+- Add node_modules watcher with debounce to auto-scan and load package types after installs.
+- Enhance TypeScript IntelliSense: recursively load all .d.ts files from packages and @types packages, add package.json as extra lib, and log progress/errors for debugging.
+- Change processContentChange signature to accept optional filePath and trigger a diagnostic refresh when new types are loaded.
+- Expose scanAndLoadNewPackageTypes to scan top-level and scoped packages and load their types.
+- Add start/stop logic for the node_modules watcher in workspace lifecycle to avoid leaks and handle cleanup.
+
+## 2025-12-31 - 3.18.0 - feat(filetree)
+add filesystem watch support to WebContainer environment and auto-refresh file tree; improve icon handling and context menu behavior
+
+- Add IFileWatcher interface and watch(...) signature to IExecutionEnvironment.
+- Implement watch(...) in WebContainerEnvironment using WebContainer's fs.watch and return a stop() handle.
+- dees-editor-filetree: start/stop file watcher, debounce auto-refresh on FS changes, cleanup on disconnect, and track last execution environment.
+- Add clipboard state (copy/cut) and related UI/menu enhancements for file operations (new file/folder, rename, delete, copy/paste).
+- dees-icon: default to Lucide icons when no prefix is provided.
+- dees-contextmenu: remove 'lucide:' prefix usage in templates and avoid awaiting windowLayer.destroy() to provide instant visual feedback.
+- Menu item shape adjusted (use { divider: true } for dividers) and various menu icon name updates.
+
+## 2025-12-31 - 3.17.0 - feat(editor)
+add file explorer toolbar, empty-space context menu, editor auto-save, save-all, and keyboard save shortcuts
+
+- Added filetree toolbar with New File / New Folder actions and toolbar styling
+- Added right-click context menu for empty filetree space to create files/folders
+- Implemented editor menu button with context menu (Auto Save toggle, Save, Save All)
+- Added auto-save toggle with 2s interval and cleanup on disconnect
+- Implemented Save and Save All APIs that persist files and update IntelliSense manager
+- Added keyboard shortcuts: Cmd/Ctrl+S to save active file and Cmd/Ctrl+Shift+S to save all
+- Made tabs scrollable with a tabs container and added an editor menu button
+
+## 2025-12-30 - 3.16.0 - feat(editor)
+improve TypeScript IntelliSense and module resolution for Monaco editor
+
+- Add file cache (fileCache) and getFileContent() for synchronous access to project files
+- Track and dispose Monaco extra libs (addedExtraLibs) and register project files via addExtraLib to enable TypeScript module resolution
+- Add addFileAsExtraLib logic to register .ts/.tsx files also under .js/.jsx paths so ESM imports resolve to TypeScript sources
+- Use ModuleResolutionKind.Bundler fallback to NodeJs and set compilerOptions (baseUrl '/', allowImportingTsExtensions, resolveJsonModule) to improve resolution
+- Adapt executionEnvironment API usage to readDir/readFile and check entry.type ('directory'|'file') instead of isDirectory/isFile
+- Add a debugging/screenshot asset: .playwright-mcp/module-resolution-fixed.png
+
+## 2025-12-30 - 3.15.0 - feat(editor)
+enable file-backed Monaco models and add Problems panel; lazy-init project TypeScript IntelliSense
+
+- dees-editor-monaco: add `filePath` property and create/get Monaco models with file:// URIs so editors are backed by real models; sync content into models and handle model switching when filePath changes; enable hover config and improved lifecycle handling.
+- dees-editor-workspace: add bottom 'Problems' panel and panel tabs (terminal/problems), diagnosticMarkers state, marker listener, UI for problem list, and navigation to file/position when a problem is clicked; initialize IntelliSense lazily when a file is opened.
+- typescript-intellisense: index project .ts/.js files from the virtual filesystem into Monaco models for cross-file resolution, enable allowNonTsExtensions and set eager model sync so TypeScript processes models eagerly.
+- General: improved handling for language changes, model language switching, and deferred initialization of the IntelliSense manager.
+- Add Playwright test images (workspace screenshots) used by CI/tests.
+
+## 2025-12-30 - 3.14.2 - fix(editor)
+bump monaco-editor to 0.55.1 and adapt TypeScript intellisense integration to the updated Monaco API
+
+- Bumped dependency monaco-editor from 0.52.2 to 0.55.1 in package.json.
+- Generated MONACO_VERSION module updated to 0.55.1 and moved target to ts_web/elements/00group-editor/dees-editor-monaco/version.ts.
+- Refactored TypeScript IntelliSense code to use a typed Monaco TS API (added IMonacoTypeScriptAPI, tsApi getter, and replaced direct monaco.languages.typescript.* calls).
+- Added test/workspace screenshot .playwright-mcp/workspace-test.png (binary asset).
+
+## 2025-12-30 - 3.14.1 - fix(build)
+bump @webcontainer/api and enable skipLibCheck to avoid type-check conflicts
+
+- Updated @webcontainer/api from 1.2.0 to 1.6.1
+- Added "skipLibCheck": true to tsconfig.json compilerOptions to suppress external library type errors
+- No breaking changes expected; this is a build/dev fix
+
+## 2025-12-30 - 3.14.0 - feat(editor)
+add modal prompts for file/folder creation, improve Monaco editor reactivity and add TypeScript IntelliSense support
+
+- Replace window.prompt for new file/folder with DeesModal + DeesInputText (showInputModal) to provide a focused modal input UX.
+- Monaco editor: add language property, handle external content updates without emitting change events (isUpdatingFromExternal), dispatch 'content-change' events, and apply language changes at runtime.
+- Add TypeScriptIntelliSenseManager to load .d.ts/type packages from the virtual filesystem (/node_modules), parse imports, load @types fallbacks, and add file models to Monaco for cross-file IntelliSense.
+- Workspace demo now mounts an initial TypeScript project and exposes initializationPromise to wait for external setup; workspace initializes IntelliSense and processes content changes to keep types up to date.
+- Export typescript-intellisense from workspace index so the manager is available to consumers.
+
+## 2025-12-30 - 3.13.1 - fix(webcontainer)
+prevent double initialization and race conditions when booting WebContainer and loading editor workspace/file tree
+
+- Add loadTreeStarted flag in dees-editor-filetree to avoid double-loading the file tree and reset it on refresh or on error to allow retries.
+- Add initializationStarted flag in dees-editor-workspace to prevent duplicate workspace initialization and reset it on initialization failure to allow retry.
+- Make WebContainerEnvironment use a shared singleton container and a bootPromise so only one WebContainer boot runs per page; instances wait for an ongoing boot instead of booting again.
+- Reset bootPromise/sharedContainer on boot failure and clear them on teardown so subsequent attempts can retry cleanly.
+
+## 2025-12-30 - 3.13.0 - feat(editor/runtime)
+Replace bare editor with Monaco-based editor and add runtime + workspace/filetree integration
+
+- Removed dees-editor-bare and replaced usages with dees-editor-monaco (includes MONACO_VERSION file).
+- Added IExecutionEnvironment interface and WebContainerEnvironment implementation (uses @webcontainer/api) to provide a browser Node/runtime API.
+- Added new components: dees-editor-filetree and dees-editor-workspace to support file tree, multiple open files, and workspace actions wired to the execution environment.
+- dees-terminal updated to accept an executionEnvironment (IExecutionEnvironment), renamed environment -> environmentVariables, provides environmentPromise (deprecated note), and now initializes/uses the provided environment to spawn shell processes and write /source.env.
+- Updated imports/usages across components (dees-input-code, dees-editor-markdown, group index exports) to use the new Monaco editor and runtime modules.
+- Behavioral breaking changes: consumers must supply an IExecutionEnvironment to components that now depend on it (e.g. dees-terminal, workspace, filetree); dees-editor-bare removal is a breaking API change.
+
+## 2025-12-30 - 3.12.2 - fix(dees-editor-bare)
+make Monaco editor follow domtools theme and clean up theme subscription on disconnect
+
+- Set initial Monaco theme from domtools.themeManager.goBrightBoolean instead of hardcoded 'vs-dark'
+- Subscribe to domtools.themeManager.themeObservable to update editor theme dynamically
+- Add monacoThemeSubscription property and unsubscribe in disconnectedCallback to avoid memory leaks
+
+## 2025-12-30 - 3.12.1 - fix(modal)
+fix modal editor layout to prevent overlap by adding relative positioning and reducing height
+
+- Added Playwright screenshots: .playwright-mcp/dees-input-code-demo.png and .playwright-mcp/modal-overlap-issue.png
+- Updated ts_web/elements/00group-input/dees-input-code/dees-input-code.ts: modal-editor-wrapper set position: relative and changed height from calc(100vh - 160px) to calc(100vh - 175px) to avoid overlap
+
+## 2025-12-30 - 3.12.0 - feat(editor)
+add code input component and editor-bare, replace dees-editor usage, and add modal contentPadding
+
+- Add new dees-input-code component (full-featured code editor input with modal, toolbar, language selector, copy and wrap toggles).
+- Introduce dees-editor-bare component and remove the legacy dees-editor implementation; update editor markdown component to use dees-editor-bare.
+- Export and include DeesInputCode in input index and include it in the unified form input types and dees-form usage.
+- Add contentPadding property to DeesModal and apply it to the modal content area (configurable modal inner padding).
+- Update element exports to point to dees-editor-bare and adjust related imports/usages.
+- Bump devDependency @design.estate/dees-wcctools from ^3.3.0 to ^3.4.0 in package.json
+
+## 2025-12-30 - 3.11.2 - fix(tests)
+make WYSIWYG tests more robust and deterministic by initializing and attaching elements consistently, awaiting customElements/firstUpdated, adjusting selectors and assertions, and cleaning up DOM after tests
+
+- Create WYSIWYG elements with document.createElement and set properties before attaching to DOM to ensure firstUpdated sees data
+- Await customElements.whenDefined and add small delays (setTimeout) so nested components finish rendering in test environments
+- Replace outdated selectors (.block.code) with .code-editor and update expectations for code block selection and language controls
+- Adjust divider expectations to check for <hr> and data-block-id instead of a divider icon; change toBeDefined -> toBeTruthy for assertions where appropriate
+- Add cleanup (document.body.removeChild) after tests to avoid leaking elements between tests
+- Relax computed font-family assertion to be platform-agnostic and verify that a fontFamily exists rather than matching 'monospace'
+- Add notes/guards around synthetic DragEvent/KeyboardEvent behavior: verify handlers/state existence and dispatch events but avoid relying on native focus/drag internals in CI
+- Update BlockRegistry render tests to assert template structure (data-block-id, data-block-type, class names) rather than final content which is populated later
+
+## 2025-12-30 - 3.11.1 - fix(tests)
+migrate tests to @git.zone/tstest tapbundle and export tap.start() in browser tests
+
+- Replaced imports from @push.rocks/tapbundle to @git.zone/tstest/tapbundle across test files
+- Replaced bare tap.start() calls with export default tap.start() in browser test files so the runner can be imported
+- Bumped devDependency @git.zone/tstest from ^3.1.3 to ^3.1.4 and removed @push.rocks/tapbundle from devDependencies
+- Changes include package.json and updates to multiple test files (11 test files)
+
 ## 2025-12-30 - 3.11.0 - feat(dees-appui-tabs)
 improve horizontal tabs UX with scroll fades, hover scrollbar, and smooth scroll-to-selected
