MD Viewer — Markdown Direction

Adds RTL/LTR direction controls to VS Code's built-in Markdown preview.

Math supports $...$, $$...$$, \(...\), and \[...\] using VS Code's bundled KaTeX renderer.

Set mdviewer.direction in Settings to one of:

• auto (default): detect direction separately for each text block.
• rtl: force right-to-left direction for text blocks.
• ltr: force left-to-right direction for text blocks.

Code blocks and math formulas remain left-to-right. The extension sets Vazirmatn as the preview font and bundles it for offline use. You can override the font with VS Code's markdown.preview.fontFamily setting.

Open a Markdown preview with Markdown: Open Preview (Ctrl+Shift+V / Cmd+Shift+V).
