OpenCode RTL Fix

Fix broken RTL text rendering in OpenCode Desktop.

Languages: فارسی | العربية

Unofficial local patch for OpenCode Desktop on macOS and Windows.

This patch improves Persian, Arabic, and RTL text rendering in:

• User messages
• Assistant messages
• Markdown paragraphs and lists
• Blockquotes
• Code blocks containing RTL text

It also applies a more readable font for Persian and Arabic characters.

Trust and scope

This project does not collect data, does not send analytics, and does not modify user projects. It only patches the installed OpenCode Desktop app.asar file and creates a local backup.

OpenCode is a separate project and is not affiliated with this repository. This license only applies to the patch scripts and files in this repository.

Requirements

• macOS or Windows
• OpenCode Desktop installed
• Node.js available in PATH
• Internet access for the first run, because the script uses npx @electron/asar

Install

Download the latest release ZIP and extract it.

macOS

Double-click:

macos/patch.command

Or run from Terminal:

./macos/patch.command

If OpenCode is installed somewhere else:

OPENCODE_APP="/path/to/OpenCode.app" ./macos/patch.command

Windows

Open PowerShell and run:

powershell -ExecutionPolicy Bypass -File .\windows\patch.ps1

If OpenCode is installed somewhere else:

powershell -ExecutionPolicy Bypass -File .\windows\patch.ps1 -AsarPath "C:\Path\To\OpenCode\resources\app.asar"

You can also pass the OpenCode install directory instead of the exact app.asar path.

After patching, fully quit and reopen OpenCode.

Restore

macOS

Double-click:

macos/unpatch.command

Or run:

./macos/unpatch.command

Windows

Run:

powershell -ExecutionPolicy Bypass -File .\windows\unpatch.ps1

The patch creates a backup next to app.asar before modifying it.

Test

Send this message in OpenCode:

سلام، این یک تست فارسی است.

Arabic test message:

مرحبا، هذا اختبار عربي.

Expected result:

• Persian and Arabic text is right-aligned and RTL.
• Punctuation appears at the correct visual end of the sentence.
• English text, paths, and normal code remain LTR.
