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 cherry-picks a commit to enhance the visual experience of the CLI by introducing adaptive ASCII art rendering for its header. It refactors the terminal detection mechanism and integrates new IDE-specific ASCII logos, which are conditionally displayed when the CLI operates within an integrated development environment. This change aims to improve the aesthetic and readability of the CLI's branding in various terminal contexts.

Highlights

• IDE-specific ASCII Art: New variants of the CLI's ASCII art logos have been introduced, specifically designed for display when the application is running within an Integrated Development Environment (IDE).
• Adaptive Header Rendering: The CLI header now intelligently detects if it's running in an IDE and, if so, uses the newly added IDE-optimized ASCII logos to ensure better visual presentation.
• Terminal Detection Refinement: The utility for detecting the current terminal program has been refactored, making the detection logic more modular and accessible for use in different parts of the application.

Code Review

This pull request introduces new ASCII art logos for IDE environments and refactors the terminal detection logic to support this feature. The changes are generally well-implemented and include new tests for the updated behavior. However, I've identified a high-severity bug in the logic that selects which logo to display. The width calculation for the logos doesn't account for the potentially different sizes of the new IDE-specific art, which can lead to layout issues like wrapping. I've provided a specific code suggestion to address this rendering bug.

[gemini-code-assist]

The logic for determining which logo to display is based on the width of the default logos (longAsciiLogo, shortAsciiLogo). However, when running in an IDE, an alternative logo (...Ide) is chosen which might be wider. This can cause the ASCII art to wrap and break the layout if the terminal width is sufficient for the default logo but not for the wider IDE logo.

For example, longAsciiLogo is 87 characters wide, while longAsciiLogoIde is 88. If the terminal width is 87, the current logic would select longAsciiLogoIde, causing it to wrap.

To fix this, the width check should consider the maximum width between the default and the IDE-specific logos to ensure the selected art always fits.

  const widthOfLongLogo = Math.max(
    getAsciiArtWidth(longAsciiLogo),
    getAsciiArtWidth(longAsciiLogoIde)
  );
  const widthOfShortLogo = Math.max(
    getAsciiArtWidth(shortAsciiLogo),
    getAsciiArtWidth(shortAsciiLogoIde)
  );
