CodeLedger v1.1.0

See CHANGELOG.md for full details.

[1.1.0] — 2026-05-07

Added

• Syntax highlighting in the Code tab of ProblemModal — regex-based tokenizer for Python, JavaScript, TypeScript, Java, C++, C, Go, Rust, Kotlin, Swift; keywords in blue, strings in green, comments in gray, numbers in amber, types in purple.
• src/lib/syntax-highlight.js — new module with highlightCode(code, lang) and cleanCode(code) helpers; no external dependencies, works inside the extension's strict CSP.
• Mermaid diagram rendering via mermaid.ink — renders diagrams as images without loading external scripts (previously blocked by extension CSP). Includes a "View in Mermaid Live" fallback link.
• Vertical-first Mermaid layout — flowcharts and graph diagrams without an explicit direction, or with LR/RL, are automatically rewritten to TD (top-down) for more readable AI-generated diagrams.
• Extension handshake v2 — presence-marker.js now dispatches a CODELEDGER_HANDSHAKE CustomEvent (in addition to the existing DOM marker) carrying the browser-specific chrome-extension:// / moz-extension:// library URL. Works on Chrome, Edge, Brave, and Firefox.
• Session-persistent install detection — landing.js caches the handshake in sessionStorage to avoid the "flash of install link" on page refresh.
• Firefox + all Chromium support for the handshake: presence-marker.js uses browser.* when available, falls back to chrome.*.
• AICommandPalette scroll — pressing ArrowDown/ArrowUp now scrolls the active item into view inside the dropdown list.
• Landing page improvements
  • Browser badges (Chrome/Brave/Edge, Firefox, GitHub Releases) dynamically linked from config.json
  • FAQ section (8 questions covering privacy, AI, platforms, BYOK)
  • Stats strip (platforms, AI providers, servers that see your code = 0)
  • JSON-LD structured data (SoftwareApplication) for better search indexing
  • Extended Open Graph and Twitter Card metadata
  • Extension-detected indicator ("Extension installed and ready") badge
  • Data attributes (data-cl-show-when-installed, data-cl-hide-when-installed) for dynamic UI based on install state
  • OpenRouter added to BYOK pills

Fixed

• Copy issue with whitespace visualization characters — Monaco editor (LeetCode) injects U+00B7 (middle dot) and U+200C (zero-width non-joiner) as visible space indicators. cleanCode() strips these before display and before writing to clipboard, so copied code is clean.
• Mermaid showed only raw code — CDN script injection was blocked by extension CSP; replaced with mermaid.ink image approach; code-block fallback now also provides an external link.
• Double-escaping in markdown tables — fixed in previous sprint; tables now render properly.
• KaTeX CSP violation — fixed in previous sprint; math blocks render as styled code spans.

Changed

• Extension version bumped to 1.1.0 in manifest.json and package.json.
• mermaid-stub.js — completely rewritten; no longer attempts CDN script injection.
• presence-marker.js — now dispatches both DOM marker and CustomEvent for maximum reliability.
• landing.js — extended with sessionStorage caching and CustomEvent listener.
• index.html — substantially expanded with FAQ, stats, browser badges, and SEO improvements.
