The chatCompletionEventHandler runs getMessageContentParts() and
removeAllDetails() on every streaming token to extract sentences
for real-time TTS dispatch via CustomEvent('chat'). These functions
perform multiple O(n) regex passes over the full accumulated message
content, resulting in O(n^2) total work over a streaming response.
The only consumer of these events is CallOverlay.svelte, which is
only mounted when showCallOverlay is true. Without the overlay open,
the parsing runs but the dispatched events have no listeners.
Wrap all three TTS parsing blocks in an if () guard
so the expensive regex work is skipped entirely for the vast majority
of users who are not using the voice call feature.
Array.unshift() is O(n) per call because it shifts all existing
elements. In a loop building an n-element array, this makes the
total cost O(n²). Replace with push() + reverse() which is O(n)
total. Produces the identical message ordering.
- Add notebook API functions (createNotebookSession, executeNotebookCell, stopNotebookSession)
- Create CellEditor component with CodeMirror for cell editing
- Rewrite NotebookView with session-based execution, Run All, Restart, Stop
- Kernel status indicator with tooltips
- Wire baseUrl/apiKey through FilePreview and FileNav
Backend emits terminal events for write_file, replace_file_content,
and run_command. Frontend showFileNavDir subscriber uses startsWith
path matching to smartly refresh only when the event is relevant:
- write_file/replace_file_content: refresh if path is in current view
- run_command: always refresh (uses root '/' which matches everything)
- Also adds copy-to-clipboard button and code preview full-height fix
- New SqliteView component with table tabs, paginated data view
(100 rows/page), SQL query editor (Cmd+Enter), NULL/BLOB formatting,
sticky column headers, and dark mode
- Supports .db, .sqlite, .sqlite3, .db3 extensions
- Uses sql.js WASM served locally from /sql.js/sql-wasm.wasm
- Also fixes display_file handling when another file is already open
- Move refresh button out of directory-only block in FileNavToolbar
- When viewing a file, refresh reloads that file's content
- When in directory view, refresh reloads the listing (unchanged)
- New NotebookView component renders markdown cells (marked+DOMPurify),
code cells (Shiki-highlighted with execution count gutter), and
outputs (text, HTML tables, base64 images, error tracebacks)
- ANSI escape codes stripped from error output
- Source toggle shows raw JSON
- Dark mode support throughout
- New JsonTreeView component with recursive collapsible nodes,
auto-expand depth, and GitHub-themed dark mode colors
- JSON/JSONC/JSON5 files show tree view by default, toggle to
Shiki-highlighted source
- SVG files show rendered preview (DOMPurify-sanitized) by default,
toggle to Shiki-highlighted XML source
- SVG removed from IMAGE_EXTS to enable text-based preview
- YAML/TOML already covered by Shiki bundled languages
- Add Shiki-powered syntax highlighting for code files with dual
light/dark themes (github-light/github-dark), line numbers, and
source/preview toggle
- Add native <video> player for mp4, webm, mov, ogv, avi, mkv
- Add native <audio> player for mp3, wav, ogg, flac, m4a, aac, opus
- New utility: src/lib/utils/codeHighlight.ts with extension-to-lang
mapping using Shiki's bundled language registry
