Convert winget output to PowerShell objects
#requires -version 7
# This crude script converts the output of the winget.exe executable into an array of PowerShell objects
# usage: winget <args> | ConvertFrom-WingetStdout.ps1
#
# examples of application:
#
# 1. Upgrade everything except some apps (e.g. managed by your employer's IT,
# or you know winget doesn't handle them properly yet)
#
# winget upgrade | ConvertFrom-WingetStdout.ps1 | ? { $_.Id -notin ('VideoLAN.VLC', 'Microsoft.Office', 'Kitware.CMake') } | % { winget upgrade --id $_.Id }
#
#
# If this code doesn't work, I dunno who wrote it.
#
# Stéphane BARIZIEN <github.nospam4sba@xoxy.net>
