claude-code - 💡(How to fix) Fix [BUG] The arrow -> in trailing return type syntax breaks C++ syntax highlighting [1 participants]

Error Messages/Logs

TL;DR

Update the syntax highlighting rules to correctly handle C++ trailing return types with arrows.

Guidance

• Review the syntax highlighting configuration to ensure it accounts for the specific syntax of C++ trailing return types, such as auto bar() -> int.
• Verify that the highlighting rules are not mistakenly interpreting the arrow as a member access operator.
• Test the syntax highlighting with various C++ code blocks containing trailing return types to identify any patterns or edge cases that may be causing the issue.
• Consider updating the Claude Code version or configuration if the issue persists, as the problem may be related to the specific version or settings being used.

Example

No specific code snippet is provided, but an example of a correctly highlighted C++ code block with a trailing return type would be:

auto foo() -> int { return 0; }

This should be highlighted as a valid C++ function declaration.

Notes

The issue may be specific to the Sonnet model or the Anthropic API, and further investigation may be needed to determine the root cause. Additionally, the lack of error messages or logs makes it difficult to provide a more specific solution.

Recommendation

Apply a workaround by updating the syntax highlighting rules to correctly handle C++ trailing return types with arrows, as this is the most likely cause of the issue.
