Add new file sync to Overleaf, Copy Comments button with file filtering

2026-03-15T03:26:36+00:00

- Sync new local files (created by Claude Code etc.) to Overleaf via REST API
- Create intermediate folders as needed, handle both text docs and binaries
- Scan for orphaned files on startup that weren't synced previously
- Add "Copy Comments" quick action: copies unresolved comments for current file
  to clipboard with line numbers, context, author names, and timestamps
- Filter comments to active file only, exclude resolved threads

Fix embedded terminal for Claude Code: PTY env, DEC 2026, xterm.js window queries

2026-03-14T03:35:05+00:00

- Add missing PTY environment variables (TERM, COLORTERM, LANG, TERM_PROGRAM)
- Strip DEC 2026 synchronized output sequences that cause xterm.js to buffer
  indefinitely when begin/end markers are split across PTY chunks
- Enable xterm.js windowOptions for terminal pixel/char size queries that
  Claude Code sends to determine rendering capabilities
- Launch Claude tab via login shell for full PATH inheritance

Fix Claude Code → Overleaf sync: remove hash from applyOtUpdate, fix OT bugs

2026-03-13T23:46:46+00:00

Root cause: SHA-1 hash sent with applyOtUpdate didn't match Overleaf's
server-side computation, causing "Invalid hash" error, disconnect, and
rollback of all synced changes.

- Remove hash field from applyOtUpdate to skip server-side hash check
- Switch applyOtUpdate from fire-and-forget to emitWithAck for reliable ack
- Fix getOldDoc bug: save base doc when changes start accumulating instead
  of incorrectly using current doc (caused wrong delete ops)
- Fix ack handler: only ack when no 'op' field (was acking remote ops too)
- Await fileSyncBridge.start() instead of fire-and-forget
- Add joinDoc retry logic for transient joinLeaveEpoch mismatch errors
- Clear pending ack callbacks on WebSocket close to prevent timeout errors
- Add otUpdateError logging for server-side rejections
- Add file-based bridge logging for debugging sync issues

Improve editing experience: KaTeX math preview, syntax highlighting, symbol autocomplete

2026-03-13T23:02:10+00:00

- Replace broken MathML math preview with KaTeX for rendered formula tooltips
- Fix syntax highlighting by using proper HighlightStyle + syntaxHighlighting() instead of non-functional CSS class overrides
- Add math region background highlighting (subtle gold tint for $...$ and $$...$$ regions)
- Add Unicode symbol previews in autocomplete for Greek letters and math operators

Use polling for file watcher to reliably detect external edits

2026-03-13T22:28:32+00:00

chokidar FSEvents is unreliable in macOS temp dirs and misses atomic
writes (write temp + rename) used by Claude Code and other editors.
Switch to usePolling with 500ms interval and atomic: true.

Separate Terminal and Claude into independent pty instances

2026-03-13T22:28:27+00:00

- Support multiple named pty instances via ID-based IPC channels
- Terminal tab spawns a shell, Claude tab spawns `claude` CLI separately
- Fix pty race condition: old instance's onExit callback could delete
  the replacement instance from the Map during React StrictMode re-mount
- Guard against StrictMode double-initialization in TerminalInstance

Add bidirectional sync for binary files (PDF, images, etc.)

2026-03-13T21:56:13+00:00

FileSyncBridge now handles binary fileRefs in addition to text docs:
- Downloads all binary files to temp dir on project connect
- Watches for binary file changes on disk and uploads via REST API
- Listens for Overleaf socket events (reciveNewFile, reciveNewDoc,
  removeEntity, reciveEntityRename) to sync remote changes to disk
- Tracks binary files by SHA1 hash to avoid redundant uploads

Add drag-and-drop file upload, fix project creation modal and API endpoints

2026-03-13T21:48:56+00:00

- Add file upload to Overleaf projects via multipart POST with correct
  "name" text field (server reads filename from req.body.name, not from
  Content-Disposition filename)
- Add drag-and-drop support in file tree panel with visual feedback
- Replace window.prompt() with custom modal for new project creation
  (prompt() returns null in Electron)
- Fix API endpoints: /api/project/new → /project/new

Add code folding, outline view, smart closing, math preview, syntax improvements

2026-03-13T20:50:40+00:00

- LaTeX code folding: \begin/\end, sections, \if/\fi, comment blocks, braces
- Outline view: section hierarchy in sidebar with click-to-navigate
- Smart closing: auto-close \begin{env} with \end{env} on Enter, $...$ auto-pair, selection surround
- Math hover preview: tooltip when hovering over $...$ expressions
- Enhanced syntax highlighting: bolder commands, better color differentiation
- Fix compile error click: jump to line works for errors without explicit file path
- Semi-transparent active line + selection highlight layering

Fix terminal cwd, selection highlight, comment range preservation

2026-03-13T07:15:10+00:00

- Terminal now spawns in project sync directory so Claude Code can
  read/write .tex files
- Selection highlight uses semi-transparent color to layer above
  active line highlight
- External edits use diff-match-patch for minimal changes instead of
  full doc replace, preserving comment highlight positions
- Set connection state on project open so status bar shows Connected
- Remove cursor:pointer from comment highlights
