PeekMD v1.0.3 - Embedded KaTeX Vector Fonts

What's New in v1.0.3

This release embeds the complete collection of official KaTeX TeX vector fonts directly into the renderer binary.

✨ What's Fixed

• Pixel-Perfect Math Accents: Fixed overlapping and misaligned accents (\hat y, \hat r, \vec v, \tilde x, \bar x, etc.) by bundling the authentic TeX font metrics directly into the offline renderer stylesheet.
• Embedded WOFF2 Font Suite: Embedded all 20 official KaTeX WOFF2 font files (KaTeX_Main, KaTeX_Math, KaTeX_AMS, KaTeX_Caligraphic, KaTeX_Size1-4, etc.) as self-contained base64 data URIs.
• 100% Offline Quick Look Typography: Guarantees authentic, publication-quality LaTeX typography across both Quick Look previews and the standalone Markdown reader without network calls.

PeekMD v1.0.2 - Bundled Offline KaTeX Math Rendering

What's New in v1.0.2

This release bundles the complete KaTeX mathematical typesetting engine (CSS, JS, and Auto-Render extension) directly into PeekMD.

✨ What's Fixed

• Full LaTeX Typesetting: Equations like \[\hat y=p+\hat r\], fractions, exponents, Greek symbols, matrices, and accents now render with full mathematical typesetting instead of displaying raw LaTeX commands in the preview.
• 100% Offline Quick Look: Because KaTeX is embedded directly in the renderer binary, mathematical typesetting works immediately in macOS Quick Look previews without requiring network access or external CDNs.
• Zero-Delay Rendering: Formulas render instantaneously on document load across both Quick Look and the standalone Markdown reader.

📦 Installation

1. Download PeekMD-v1.0.2.dmg below.
2. Open the DMG and drag PeekMD into your Applications folder.

PeekMD v1.0.1 - LaTeX Math Rendering Fixes

What's New in v1.0.1

This patch release fixes LaTeX mathematical typesetting when using LaTeX display bracket delimiters \[ ... \] and expands math formatting capabilities across Quick Look and the standalone reader.

🐛 Bug Fixes & Improvements

• LaTeX Display Bracket Math (\[ ... \]): Fixed an issue where \[ ... \] display equations were stripped of backslashes by the CommonMark parser and rendered as plain text [ \text{...} ].
• Expanded LaTeX Environment Support: Added native handling for LaTeX environments such as \begin{align}...\end{align}, \begin{equation}...\end{equation}, \begin{cases}...\end{cases}, \begin{gather}...\end{gather}, etc.
• Single-Line Math Blocks: Fixed support for single-line $$ ... $$ and \[ ... \] expressions.
• Inline LaTeX Math (\( ... \)): Protected inline parentheses math from CommonMark escape stripping and markdown underscore italicization (_).
• Code Block Protection: Ensured math-like tokens inside code blocks and inline code spans are preserved without modification.

PeekMD v0.2

PeekMD v0.2 - Next-Generation AST Markdown Engine 🚀

PeekMD v0.2 introduces a completely overhauled Markdown parser and rendering architecture powered by Apple's official swift-markdown (backed by cmark-gfm), bringing full GitHub-Flavored Markdown compliance, safe raw HTML rendering, token-based syntax highlighting, local LaTeX math typesetting, and enhanced Obsidian callout support to both macOS Quick Look and the standalone PeekMD viewer.

---

✨ What's New in v0.2

🧠 Full AST Markdown Parser (swift-markdown)

• Replaced the line-oriented regex parser with Apple's official swift-markdown / cmark-gfm AST parser.
• Reliable CommonMark & GitHub-Flavored Markdown parsing with accurate AST node traversal.
• Proper nested list hierarchies, multiline list items with continuation paragraphs, code blocks, and blockquotes.
• ATX (# H1 .. ###### H6) and Setext (===, ---) headings with auto-generated anchor IDs for document navigation.
• GFM table alignments (:---, :---:, ---:) with escaped pipe \| support and horizontal scroll wrappers.

🛡️ Safe Raw HTML & GitHub README Compatibility

• Full support for standard GitHub README HTML markup: <div align="center">, <img width="420">, <details>, <summary>, <kbd>, <mark>, <sub>, <sup>, and raw tables.
• Built-in HTML sanitization that automatically rejects <script>, <iframe>, <object>, and on* event handlers.
• HTML comments are automatically hidden/stripped from visible output.

🎨 Single-Pass Tokenized Syntax Highlighting

• Fixed regex corruption over generated HTML tags by introducing a single-pass, token-based syntax scanner.
• Source code is tokenized into non-overlapping intervals (keyword, string, comment, number, type, function, property, tag) and escaped exactly once.
• Zero class="token-string"> text pollution across Swift, TypeScript/JS, JSON, Bash, HTML, C/C++, Rust, Go, Python, SQL, and CSS.

🖼️ Robust Local Image & Asset Resolution

• Directory-aware relative path lookup for sibling assets (assets/logo.png), parent paths (../images/img.png), and percent-encoded paths.
• Local images are automatically embedded as Base64 data:<mime>;base64,... data URIs, enabling sandbox-safe rendering in both Quick Look previews and WebKit views.

📐 Local LaTeX / Math Typesetting

• Bundled local KaTeX stylesheets and auto-render engine with zero external CDN dependencies.
• Inline math ($E = mc^2$) and display math blocks ($$\int_{-\infty}^{\infty} e^{-x^2}\,dx = \sqrt{\pi}$$).
• Currency values ($50 and $100) are protected from accidental math conversion.

📑 Obsidian Callouts & Wikilinks

• 13 Obsidian callout styles: NOTE, TIP, IMPORTANT, WARNING, CAUTION, INFO, SUCCESS, QUESTION, FAILURE, DANGER, BUG, EXAMPLE, QUOTE.
• Native foldable callout support: > [!NOTE]+ (expanded by default) and > [!NOTE]- (collapsed by default) using semantic HTML5 <details> and <summary>.
• Wikilink support: [[Target]], [[Target|Alias]], [[Target#Section]], [[Target#^block]], and image embeds ![[assets/image.png|300]].

📱 Layout Overflow Protection

• Universal overflow-wrap: break-word and max-width: 100% across all 4 themes (System, GitHub, Minimal, Academic) preventing document-wide horizontal scrollbars.
• Responsive table containers with dedicated horizontal scrolling.
