* feat(desktop): add CodeMirror deps + bundle budget + encoding utils
Phase 2 foundation pieces (tasks 6-7 of editor-lsp-foundation):
- Add 9 @codemirror/* dependencies (state, view, commands, search, language,
autocomplete, lang-{javascript,json,markdown}). Tree-shaking keeps the
current bundle delta at +0.00 KB until WorkspaceEditor.tsx imports them
in task 8.
- Add scripts/check-bundle-budget.ts + bun script "check:bundle-budget".
Asserts dist/assets/*.js gzipped total <= baseline + 100 KB. Baseline
captured at origin/main @ 95931d49 (post-R5, pre-CodeMirror) = 3299.76 KB.
- Add encodingDetect.ts: detectEncoding(bytes) -> 'utf-8' | 'utf-8-bom' |
'unsupported' (uses TextDecoder fatal:true to map invalid UTF-8 to
unsupported); detectLineEnding(text) -> 'LF' | 'CRLF' | 'CR' (dominant
style with LF as fallback for empty/single-line buffers).
Tested:
- bun run test src/components/workspace/encodingDetect.test.ts -- --run (18/18 pass)
- bun run scripts/check-bundle-budget.ts (OK, +0.00 KB delta)
_Requirements: 1.3, 1.6, 1.7, 1.8_
* feat(server,desktop): workspace file save endpoint + buffer/conflict store
Phase 2 backend pieces (tasks 9-12 of editor-lsp-foundation):
Server:
- src/server/events/workspaceFileSaved.ts: shared emitter
emitWorkspaceFileSaved() so both write paths (user now, agent in PR-4)
funnel through one well-typed WS message shape.
- src/server/services/workspaceFileService.ts: WriteWorkspaceFileSchema
(Zod), atomic write (temp file + fsync + rename, Windows EBUSY/EPERM
retry 3x50ms), realpath-based symlink containment, BOM/CRLF/CR
round-trip, sha256 stale-base check (409 on hash mismatch), structured
400/404/409/500 error bodies, post-write workspace.file.saved emit.
- src/server/api/sessions.ts: POST /api/sessions/:id/workspace/file
routes through new handleSessionWorkspacePost; GET path unchanged.
- src/server/services/workspaceFileService.test.ts: 17 tests covering
200 / 400 (bad request, path-escape, parent-missing, absolute-path) /
404 session-missing / 409 stale-base / BOM round-trip / CRLF round-trip /
CR round-trip / temp-file-not-leaked / 10 MiB content cap. Includes
symlink-escape coverage on POSIX (skipped on Windows where symlink
creation needs elevation).
Desktop store:
- desktop/src/stores/workspacePanelStore.ts: bufferStateByTabId record,
WorkspaceBufferState/Conflict types, initBuffer / setBufferState /
applyExternalSave / acknowledgeConflict / clearBuffer actions.
applyExternalSave is the WS-driven entry point — clean buffers rebase
silently when content is supplied; dirty buffers raise a conflict
banner. acknowledgeConflict('reload') resets to base, 'keepMine' /
'openConflict' just dismiss the banner. closePreviewTabs and
clearSession now drop matching buffer state to prevent leaks.
Tested:
- bun test src/server/services/workspaceFileService.test.ts (17/17 pass)
- bun run lint (server tsc clean)
- bun run test src/stores/workspacePanelStore.test.ts (24/24 pass — store
extension is purely additive, R5 tests still green)
Note: pre-existing e2e/business-flow failures in src/server/__tests__/e2e
remain untouched by this change (44 fails on baseline, no new fails
introduced).
_Requirements: 1.5, 2.1-2.9, 3.1-3.3_
* feat(desktop): WorkspaceEditor + ConflictBanner + UnsavedChangesModal
Phase 2 UI pieces (tasks 8, 13, 14, 15 of editor-lsp-foundation):
- desktop/src/components/workspace/WorkspaceEditor.tsx: CodeMirror 6
editor wrapping the workspace panel buffer state. Hooks
EditorView.updateListener -> setBufferState for live dirty tracking,
picks language by extension (ts/tsx/js/jsx/json/md), wires Save to
sessionsApi.saveWorkspaceFile (R2 atomic write endpoint), refreshes
base hash on success, falls back to a read-only message when
detectEncoding returns 'unsupported'. External rebases (e.g. clean
buffer applyExternalSave) are pushed back into the EditorView via
dispatch.
- desktop/src/components/workspace/ConflictBanner.tsx: clean buffer ->
single Reload button; dirty buffer -> three buttons (Reload (discard),
Keep mine, Open conflict view). Renders workspace-relative path,
hash first 8 hex, relative timestamp refreshing every 60 s.
- desktop/src/components/workspace/UnsavedChangesModal.tsx: Discard /
Save / Cancel modal. Cancel is the default focus, Esc triggers it.
While saving, all three buttons disable and the host calls onSave
which only resolves close on success. 30 s in-prompt timeout fires
onTimeout (host owns the toast).
- desktop/src/components/workspace/WorkspaceEditor.test.tsx: 8 RTL
tests covering buffer init / encoding detection / unsupported
fallback / dirty marker / unsaved-changes modal flows / conflict
banner clean-vs-dirty layouts.
- desktop/src/api/sessions.ts: SaveWorkspaceFileInput +
SaveWorkspaceFileResult types and sessionsApi.saveWorkspaceFile
POST helper.
Bundle delta: +0.28 KB gz (CodeMirror 6 + 3 lang packs imported but
WorkspaceEditor is not yet wired into WorkspacePanel — that integration
ships in a follow-up PR alongside Phase 3 LSP work, keeping this PR
focused on the foundation).
Tested:
- bun run lint (tsc --noEmit clean)
- bun run test (workspacePanelStore 24/24, encodingDetect 18/18,
WorkspaceEditor 8/8, WorkspacePanel 27/27 — 77/77 across 4 files)
- bun run check:bundle-budget (delta +0.28 KB gz, 99.72 KB headroom)
- bun run build (clean, 1.20s)
_Requirements: 1.1-1.8, 3.2-3.5, 4.1-4.6_

Claude Code Haha
A Claude Code build repaired from the source leaked from Anthropic's npm registry on 2026-03-31. Claude Code Haha is now primarily a desktop Claude Code workspace for macOS, Windows, and Linux: sessions, projects, branch / Worktree launch, right-side file changes, code diffs, permission review, provider setup, Computer Use, H5 remote access, IM integration, and scheduled tasks in one app.

Desktop Preview
The Claude Code Haha desktop app brings sessions, multi-project navigation, branch / Worktree controls, right-side file changes, code diffs, permission review, provider setup, and remote access into one graphical workspace for daily development flows beyond the terminal.

Install the Desktop App
- Download the macOS / Windows / Linux desktop installer from Releases.
- On first launch, configure your model provider, API key, and default model in Settings.
- This build is currently unsigned, so the first launch needs a one-time manual approval (clear quarantine on macOS, click "Run anyway" on Windows). See the desktop installation guide.
Run the CLI from Source
For users who want to debug the underlying CLI, server, or local development flow:
bun install
cp .env.example .env
./bin/claude-haha
See environment variables and global usage for more configuration options.
Desktop Highlights
- Multi-session workspace: tabs, project switching, terminal entry, and session history in one place.
- Branch / Worktree launch: choose a repository branch and decide whether to use the current working tree or an isolated Worktree.
- Right-side file changes: review changed files, added/removed lines, and current workspace state while chatting.
- Visual code changes: inspect edits, file writes, and diffs directly in the desktop app.
- Permission review: approve risky commands, tool calls, and model follow-up questions in the GUI.
- Multi-provider setup: configure Anthropic-compatible APIs, third-party models, WebSearch fallback, and local options.
- Computer Use: let the agent take screenshots, click, type, and control desktop apps after authorization.
- H5 remote access: open the current desktop session from a phone or another device with a one-time token.
- IM integration: chat, switch projects, and approve actions through Telegram / Feishu / WeChat / DingTalk.
- Scheduled tasks and usage stats: create planned tasks and track local token usage trends.
