Summary of Changes

Hello @gemini-cli-robot, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request aims to integrate a critical bug fix into an upcoming preview release by automatically cherry-picking a commit. The fix specifically resolves a regression in the CLI's text buffer component, ensuring that cursor navigation with up and down arrow keys works as expected on lines that wrap across multiple visual lines. Due to merge conflicts encountered during the automated process, manual intervention is required to resolve these conflicts before the fix can be fully applied and the new preview version released.

Highlights

• Automated Cherry-Pick: This PR is an automated cherry-pick of commit 8cae90f to the release/v0.27.0-preview.6-pr-18108 branch, intended to create version 0.27.0-preview.7.
• Regression Fix: Addresses a regression where up/down arrow navigation did not function correctly on wrapped lines within the text buffer component.
• Cursor Logic Update: The logic for handling MOVE_UP and MOVE_DOWN commands in useTextBuffer has been updated to correctly account for visual line wrapping by using visualCursor and visualLines.
• New Regression Test: A dedicated test case has been added to text-buffer.test.ts to ensure the correct behavior of up/down arrow movement on wrapped lines.
• Merge Conflicts: The cherry-pick operation resulted in merge conflicts in packages/cli/src/ui/components/shared/text-buffer.ts that require manual resolution.

Changelog

• packages/cli/src/ui/components/shared/text-buffer.test.ts
  • Added a new regression test case to validate correct up/down arrow navigation on wrapped text lines.
• packages/cli/src/ui/components/shared/text-buffer.ts
  • Modified the handleInput function to use visualCursor[0] for MOVE_UP and visualLines.length - 1 for MOVE_DOWN boundary checks, improving cursor behavior on wrapped lines.
  • Introduced merge conflicts in the dependency array of a useCallback hook, requiring manual resolution.

Activity

• The pull request was automatically generated by gemini-cli-robot to perform a cherry-pick.

Code Review

This pull request cherry-picks a fix for a regression in up/down arrow key navigation on wrapped lines, and adds a corresponding regression test. The fix itself appears correct, but a merge conflict was not resolved properly, leaving conflict markers in the code. This is a critical issue that will prevent the code from compiling and must be addressed.

[gemini-code-assist]

It appears there are unresolved merge conflict markers left in the code. This will cause a syntax error and prevent the code from compiling. Please remove the markers. The dependencies visualCursor and visualLines are correctly added as they are now used in handleInput, but setText and text appear to be unused in this callback and can be omitted.
