📝 Walkthrough

Walkthrough

Install.ps1 modifies two git-related functions to prevent PowerShell 5.1 from treating native-command stderr as terminating errors. Update-Repository and Install-Repository now temporarily relax $ErrorActionPreference to "Continue" and detect failures via $LASTEXITCODE instead.

Changes

PowerShell Native Command Error Handling

Layer / File(s)	Summary
Git operation error handling with relaxed preferences install.ps1	Both Update-Repository (lines 191–197) and Install-Repository (lines 261–269) temporarily set $ErrorActionPreference = "Continue" around git commands to prevent stderr from triggering termination, and shift failure detection to explicit $LASTEXITCODE checks. Install-Repository also adds an explicit failure message and exit 1 on clone failure.

Poem

🐰 A script that feared each warning's cry,
Now handles errors with stderr's sigh—
Exit codes guide where warnings roam,
And git commands find their way home! 🚀
