Add a persistent wrap/nowrap toggle button in the code block header bar,
consistent with the existing tool call content viewer. Persisted in
localStorage. Default is nowrap (existing behavior).
Add toggle in chat input to switch between Enter-to-send (default)
and Ctrl+Enter-to-send modes. Preference persists in localStorage.
Keyboard shortcuts modal reflects the current setting.
When scrolled up and new messages arrive, the scroll-to-bottom button
now shows a count badge (e.g. '3', '99+') instead of just bouncing.
This gives users a clear sense of how many messages they missed.
Clickable example prompts appear when a session has no messages,
giving users quick-start ideas. 2x2 grid on desktop, stacked on mobile.
Fully i18n'd (EN/FR).
Fix: reconcile deleted-sessions blacklist against gateway on each refresh. Permanent sessions like agent:main:main auto-recover from accidental deletion. Closes#3
- Remove font-style:italic from .ht-italic (different glyph widths cause desync)
- Remove font-weight:600 from .ht-heading (bolder glyphs are wider)
- Remove background/border-radius from code token spans
- Remove text-decoration from .ht-link
- Token spans now ONLY use color — zero text geometry changes
- Use inherit for font-size/line-height in shared .ht-backdrop/.ht-textarea
- Add update check hook: polls GitHub releases, shows indicator in sidebar
- #63: 'New messages' label only shows when actual new messages arrive while scrolled up; plain arrow button shown otherwise
- #64: Fix cursor desync in HighlightedTextarea by matching backdrop border width to textarea
- #65: Move floating buttons inside scroll container with sticky positioning to prevent overlap with growing textarea
- #66: Graceful fallback to Bot icon when agent avatar image fails to load
- Show line numbers for code blocks with more than 3 lines
- Toggle button (# icon + line count) in the language header bar
- Preference persisted in localStorage
- Line numbers are non-selectable (won't copy with code)
- Hidden for short snippets to reduce visual noise
Consecutive messages from the same role within 2 minutes are visually
grouped: subsequent messages hide the avatar (keeping alignment) and
use tighter vertical spacing. Date separators and role changes break
groups. This matches modern chat UX patterns (Discord, Telegram).
Track how long each assistant response took to generate and display
it subtly next to the timestamp (e.g. '· 12.3s'). The timing is
measured from the first streaming delta to the final state, and
preserved across the history reload that follows stream completion.
Only visible for messages generated during the current session.
- Set document.documentElement.lang on initial load and locale change
- Ensures screen readers and browser features respect the active language
- Removes duplicate aria-label on MessageSearch input
Adds a consistent focus ring (accent-dim color, 2px) on all focusable
elements when navigated via keyboard (:focus-visible). Mouse/touch clicks
no longer show the default browser outline (:focus:not(:focus-visible)).
Elements with existing Tailwind focus:ring-* classes are unaffected since
they already handle their own focus styling.
- Replace raw text timestamps with <time> HTML elements
- Add dateTime attribute (ISO 8601) for accessibility and machine readability
- Add title attribute showing full date+time on hover (weekday, date, time with seconds)
- Localized tooltip using the user's language preference
- Helps users see exact timestamps for older messages shown as abbreviated times
Move react-markdown, remark-gfm, remark-breaks, and rehype-highlight
imports from eager to dynamic via a LazyMarkdown wrapper component.
The ~336KB markdown bundle is now loaded on-demand after initial paint
instead of blocking the critical rendering path.
- Create LazyMarkdown component with Suspense fallback
- Pre-load plugins in parallel on module init
- Replace all ReactMarkdown usage in ChatMessage with LazyMarkdown
- Hide sidebar, header, chat input, and scroll button when printing
- Reset backgrounds to white, text to black for readability
- Code blocks get light background with borders
- Tool calls styled for print (compact, bordered)
- External links show their URL in parentheses
- Chat scroll area becomes fully visible (no overflow)
- Messages avoid page-break-inside for clean pagination
- Remove shadows and backdrop filters in print
- Replace div with <main> for primary chat pane (screen reader landmark)
- Replace div with <section> for split pane
- Add skip-to-content link for keyboard navigation (Tab → jump to chat input)
- Add aria-expanded and aria-label to tool call badge buttons
- Add id='chat-input' to textarea for skip link target
- Add i18n keys for new ARIA labels (EN + FR)
The SW cache name was hardcoded to 'pinchchat-v1', meaning PWA users
would get stale cached assets forever. Now the cache name includes
the package version and build timestamp, so each build creates a new
cache and old ones are cleaned up on activation.
Also adds:
- Periodic SW update check (every 30 min)
- Auto-reload when new SW version is detected
Add c, cpp, and java to the highlight.js language bundle for code block
rendering. These are among the most commonly used languages in AI coding
conversations and were previously unsupported, falling back to plain text.
Also adds aliases: h (C headers), cc/cxx/c++/hpp/hxx (C++ variants).
- Wrap ChatMessageComponent with React.memo to skip re-renders when props unchanged
- Hoist remarkPlugins and rehypePlugins arrays to module scope to avoid
creating new array references on every render (prevents unnecessary
ReactMarkdown re-processing)
- Use proper PluggableList type from unified instead of any
- ThemeSwitcher: aria-expanded, aria-haspopup, aria-pressed on theme/accent buttons, Escape to close, dialog role
- ThinkingBlock: aria-expanded on toggle, region role on content
- ThinkingIndicator: role=status, aria-label, decorative icon aria-hidden
- ErrorBoundary: role=alert on error state
- SessionIcon: aria-hidden on decorative SVG brand icons
Tailwind's preflight resets list-style to none on ul/ol elements.
Add explicit list-style-type rules for markdown-body: disc for ul,
decimal for ol, with circle/square for nested levels.
Also add li margin for spacing.
Closes feedback #61
- Expose resolvedTheme in ThemeContext for theme-aware rendering
- Tool call badges: darker text colors and higher bg opacity in light theme
- User message bubbles: increased bg opacity and border strength in light theme
- Progress bars and send button already use accent CSS variables (no change needed)
Closes feedback #60
- User messages appear instantly with 'sending' state (dimmed, clock icon)
- Transitions to 'sent' (checkmark) when server acknowledges
- Shows error state (alert icon, retry visible) if send fails
- Applied to both primary and secondary sessions
- Set up Vitest with 27 tests across 3 test suites
- relativeTime: edge cases, time buckets, future timestamps
- sessionDisplayName: labels, kinds, channels, UUID truncation
- messagesToMarkdown: roles, blocks, tool calls, system events
- Add test and test:watch npm scripts
- Add test step to CI workflow
WebSocket debug logs are now silent by default. Enable with:
localStorage.setItem('pinchchat:debug', '1')
Reduces console noise in production while keeping full debug
visibility available for developers.
Replace highlight.js/lib/common (36 languages) with a curated subset
of 16 languages relevant for coding-assistant chat UIs. Both ToolCall
(direct hljs) and ChatMessage (rehype-highlight) now share the same
custom bundle from src/lib/highlight.ts.
Languages included: bash, css, diff, dockerfile, go, ini, javascript,
json, markdown, python, rust, shell, sql, typescript, xml, yaml.
Markdown chunk: 477KB → 336KB (-30%, -45KB gzipped)
