Changes

• Simplify the description for clarity and consistency.
• Refactor the ~/.profile creation logic into pre_install with better error handling and cleaner PowerShell syntax.
• Replace the massive static bin array (which occupied nearly 900 lines) with a dynamic post_install script that shims tools based on busybox.exe --list.
• Implement a dynamic uninstaller to ensure all generated shims are purged during removal.
• Update checkver regex to target w64 assets for accuracy.

Notes

• Synchronization & Cleanliness: This approach solves the "ghost shim" problem. If a future version of uutils adds or removes a utility, the dynamic script will only create shims for what actually exists in the binary.
• Architecture Aware: Different architectures (x64 vs. ARM64) might support different subsets of tools. By querying the binary at install time, we ensure the shims are accurate for the specific environment.
• Maintainability: Reduces the manifest size by ~90%, making it significantly easier to audit and maintain.
• Due to issues in certain logic within Scoop Core, errors may occur when updating or removing [.shim file.
  • See: [Bug] Wildcard error when shim name contains brackets: "The specified wildcard character pattern is not valid: [.shim" Scoop#6592

Testing
