MarkdownViewer

Markdown → TMP — Lightning-fast Markdown renderer for TextMesh Pro

Key Features

• One-click component: just add the “Md Label” script and paste your Markdown.
• Full support for GitHub Flavoured Markdown: headings, lists, links, code fences, tables and inline formatting.
• Built-in syntax highlighting for Python, JavaScript, TypeScript, Bash, and Rust.
• Automatic conversion of Markdown tables into perfectly aligned monospace ASCII tables.
• No external DLLs required – includes lightweight Markdig and optional ColorCode highlighters as C# source.
• Editor live preview via Unity’s OnValidate mechanism.

Dependencies and Requirements

• Unity 2021.3 LTS or newer (supports all render pipelines).
• TextMesh Pro version 3.0.6 or later (installable via Unity Package Manager).
• Uses Markdig 0.30+ for Markdown parsing and System.Text.RegularExpressions for highlighting: https://github.com/xoofx/markdig
• Optional: Define COLORCODE_INSTALLED in your scripting symbols to use ColorCode-based highlighting instead of the default engine.
• Thaleah Font: https://tinyworlds.itch.io/free-pixel-font-thaleah
• JetBrains Mono Font: https://www.jetbrains.com/lp/mono/

Package Contents

• 12 C# source files (clean, documented, no DLLs or native plugins)
• 2 SDF font asset: JetBrainsMono-Regular for code blocks and Thaleah Fat for Pixel Font
• 0 Editor scripts – runtime only, no pollution of the Unity Editor namespace

Limitations and Transparency

• Inline raw HTML, footnotes, and definition lists are currently not supported.
• Extremely large documents (over 10,000 lines) may cause temporary string allocations; consider splitting.
• The highlighter registry is not thread-safe – register or modify highlighters on the main thread only.
• TextMesh Pro’s rich-text tags rely on correct color space settings. For URP or HDRP projects, use Linear color space for accurate display.
