[wu21-web]

Copilot Summary

This pull request updates both the pixeval and pixeval@cn casks to add Linux support, refactor architecture handling, and update to version 5.0.12. The changes streamline platform-specific logic, add new checksums, and ensure parity between the international and China-specific versions.

Platform and Architecture Support Updates:

• Added Linux support to both pixeval and pixeval@cn, including URLs for downloading AppImage files and cleanup instructions via zap. [1] [2]
• Refactored architecture handling by introducing the arch variable and removing separate on_arm/on_intel blocks, simplifying URL and SHA256 assignment for both macOS and Linux. [1] [2]

Version and Integrity Updates:

• Updated both casks to version 5.0.12 and provided new SHA256 checksums for all supported platforms and architectures. [1] [2]

Cask Metadata and Consistency:

• Moved the name, desc, and homepage fields to the end of each cask and ensured they are consistently defined. [1] [2]
• Ensured pixeval@cn continues to declare a conflict with the main pixeval cask.

🟢 Approval recommended

The cask DSL changes are consistent and the macOS/Linux URLs, arch mapping, and multi-platform SHA256 structure align with known Homebrew cask patterns.

Pull request overview

This pull request updates the pixeval and pixeval@cn Homebrew casks to ship Pixeval v5.0.12 with first-class Linux support, while simplifying multi-arch handling across macOS and Linux.

Changes:

• Bumped both casks from 5.0.11 to 5.0.12 and updated SHA256 values for macOS (arm/intel) and Linux (arm64/x86_64).
