claude-code - 💡(How to fix) Fix [BUG] Fullscreen TUI mode doesn't normalize \r\n on paste — ^M characters and doubled blank lines [1 comments, 2 participants]

TL;DR

The issue can be worked around by disabling fullscreen TUI mode or cleaning the clipboard content to remove \r characters before pasting.

Guidance

• The problem seems to be related to how the fullscreen TUI mode handles \r\n line endings, which are not normalized to \n as expected.
• To verify the issue, follow the provided steps to reproduce and observe the ^M characters or extra blank lines in the pasted content.
• A temporary workaround is to use the provided command pbpaste | tr -d '\r' | pbcopy to clean the clipboard content before pasting.
• The issue is specific to fullscreen TUI mode, and standard mode handles paste correctly, suggesting a regression in the fullscreen TUI implementation.

Example

No code snippet is provided as the issue does not require a code change, but rather a configuration or workaround.

Notes

The provided workaround is a temporary solution, and a proper fix would involve modifying the fullscreen TUI mode to correctly handle \r\n line endings. The issue is also related to a previously closed duplicate (#22385), which had the same symptom but in a different environment.

Recommendation

Apply the workaround by disabling fullscreen TUI mode or using the pbpaste | tr -d '\r' | pbcopy command to clean the clipboard content before pasting, as this is the most straightforward way to mitigate the issue until a proper fix is available.
