Claude Vazirmatn Font

Persian Vazirmatn font and RTL support for the Anthropic Claude Code extension in VS Code.

What it does

• Applies Vazirmatn font to the Claude Code webview UI
• Switches the UI to right-to-left layout
• Keeps code blocks, terminal output, Monaco editor and icons in left-to-right

How it works

Claude Code's webview uses a strict Content Security Policy: inline scripts and inline styles are blocked. This extension patches Claude's webview/index.css by appending a managed CSS block (wrapped in /* claude-vazirmatn-font:start */ ... /* claude-vazirmatn-font:end */ sentinels) and ships the Vazirmatn font next to it so the webview origin can load it.

The managed block is re-applied automatically whenever Claude Code is updated, and is cleanly removed when you uninstall this extension.

Settings

• claudeVazirmatnFont.enabled — master toggle
• claudeVazirmatnFont.patchOnStartup — apply on VS Code startup
• claudeVazirmatnFont.showReloadPrompt — prompt to reload after patching
• claudeVazirmatnFont.preferredFontFamily — override the primary UI font

Commands

• Apply Persian RTL Patch — patch now
• Check Claude Compatibility — verify the installed Claude folder is patchable
• Restore Original Claude Files — revert changes, keeps settings
• Full Cleanup and Reset Managed Settings — revert changes and remove our settings

Known limitations

• RTL CSS is tuned against Claude Code 2.1.x webview structure. Future Claude releases may introduce new class names or layout primitives that need additional CSS rules.
• The patcher writes to a file inside Claude Code's extension folder. VS Code will flag Claude Code as "tampered" on the next update until Claude is re-patched (this extension handles the re-patch automatically on startup).
