Original Pull Request: https://github.com/anomalyco/opencode/pull/11033

State: closed
Merged: Yes

Summary

Fixes #10979

Enable nonStandard: true in marked-katex-extension to allow inline math expressions to be immediately followed by punctuation like ), ], }, ;, etc.

Problem

When inline math delimited with $...$ is immediately followed by punctuation (e.g., $\alpha$)), the math fails to render. This is because the standard regex in marked-katex-extension only allows whitespace and limited punctuation after the closing $.

Solution

The marked-katex-extension package already provides a nonStandard option that removes this restriction, allowing any character to follow the closing delimiter. This is the minimal change to fix the issue.

Changes

  • packages/ui/src/context/marked.tsx (+1 line): Add nonStandard: true to markedKatex config

Test Plan

  • In the web UI, enter $\alpha$) in a chat message
  • Expected: The Greek letter alpha followed by a closing parenthesis
  • Previously: KaTeX parsing error / math not rendered
