• Tweak the logo to look ok in the Mac Terminal

Updated mac terminal logo

Leave logo the same on other terminals and fix issue showing username due to static content.

Revert change to use useEffect breaking showing the username at login because it is not visible until after the component is rendered to static.

Fixes #20924

Summary of Changes

Hello, 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 focuses on improving the user interface experience and addressing a critical rendering bug. It introduces a conditional logo display to ensure visual integrity across different terminal environments, specifically Mac Terminal, and refactors user identity logic to guarantee immediate display of user information upon login, enhancing responsiveness and user feedback.

Highlights

• Mac Terminal Logo Tweak: The CLI logo has been adjusted to display correctly within the Mac Terminal, addressing visual inconsistencies caused by line-height padding.
• User Identity Rendering Fix: A regression where the username was not visible at login until after the component rendered statically has been resolved by reverting the use of useEffect for email retrieval.

Changelog

• packages/cli/src/ui/components/AppHeader.tsx
  • Implemented conditional rendering for the CLI logo, displaying a MAC_TERMINAL_ICON when isAppleTerminal is true and DEFAULT_ICON otherwise.
  • Imported isAppleTerminal utility from @google/gemini-cli-core.
• packages/cli/src/ui/components/AppHeaderIcon.test.tsx
  • Added a new test file to verify the correct rendering of the AppHeader icon.
  • Included tests to assert that the default icon is rendered in standard terminals and the symmetric icon is rendered in Apple Terminal.
  • Mocked the isAppleTerminal function to control test scenarios.
• packages/cli/src/ui/components/StatusDisplay.test.tsx
  • Refactored environment variable handling in tests to use vi.stubEnv and vi.unstubAllEnvs for improved test isolation and cleanup.
  • Moved GEMINI_SYSTEM_MD environment variable initialization to a beforeEach hook.
• packages/cli/src/ui/components/UserIdentity.test.tsx
  • Added a regression test to confirm that the user's email is rendered on the very first frame, preventing a previous rendering delay.
• packages/cli/src/ui/components/UserIdentity.tsx
  • Refactored the email retrieval logic from useState and useEffect to useMemo to ensure synchronous availability of the user's email.
  • Removed unused useEffect and useState imports.
• packages/cli/src/ui/components/snapshots/AppHeaderIcon-AppHeader-Icon-Rendering-renders-the-default-icon-in-standard-terminals.snap.svg
  • Added SVG snapshot for the default header icon rendering.
• packages/cli/src/ui/components/snapshots/AppHeaderIcon-AppHeader-Icon-Rendering-renders-the-symmetric-icon-in-Apple-Terminal.snap.svg
  • Added SVG snapshot for the Apple Terminal specific header icon rendering.
• packages/cli/src/ui/components/snapshots/AppHeaderIcon.test.tsx.snap
  • Added Vitest snapshot for AppHeaderIcon.test.tsx.

Code Review

This pull request introduces a fix for rendering the CLI logo correctly in Apple Terminal by conditionally displaying a symmetric icon. It also resolves a regression where the user's email was not immediately visible at login by refactoring the UserIdentity component to use useMemo instead of useEffect for fetching the cached Google account. New snapshot tests have been added for the AppHeader icon rendering, and StatusDisplay tests have been updated to align with the recommended vi.stubEnv and vi.unstubAllEnvs pattern for environment variables. The changes are well-implemented and directly address the stated objectives.
