function Get-UpdateToolInventory { <# .SYNOPSIS Reports what this machine has of the tools Update-Everything drives. .DESCRIPTION One record per tool, with Name, Command, Present, Version, Owner and Copies. Every step already resolves its own tool and skips when it is absent, so this changes no behaviour. What it adds is a picture: on a first run the summary is a long column of skips, and nothing says whether that is a machine with little installed or a run that went wrong. Owner comes from Get-ToolInstallSource and answers who is responsible for updating a tool. Copies counts the distinct directories an executable of that name resolves from; more than one is worth knowing, because the version reported here is the one that runs and the others are updated by nobody. Directories rather than files, because PATHEXT resolves npm.cmd and npm from the same folder as two commands. That is one install, and reporting it as two would train people to ignore the warning. A tool that fails or hangs on its version argument reports Present with a null Version rather than failing the inventory. Knowing something is there is most of the value. .PARAMETER Catalogue The tools to look for. Defaults to the ones this module drives; a test passes its own. .EXAMPLE Get-UpdateToolInventory | Where-Object Present #> [CmdletBinding()] [OutputType([pscustomobject])] param( [object[]] $Catalogue ) if (-not $Catalogue) { # Name is what a person calls it; Command is what resolves on PATH. $Catalogue = @( @{ Name = 'winget'; Command = 'winget'; VersionArgument = '--version' } @{ Name = 'Chocolatey'; Command = 'choco'; VersionArgument = '--version' } @{ Name = 'Scoop'; Command = 'scoop'; VersionArgument = $null } @{ Name = 'PowerShell 7'; Command = 'pwsh'; VersionArgument = '--version' } @{ Name = 'Node.js'; Command = 'node'; VersionArgument = '--version' } @{ Name = 'npm'; Command = 'npm'; VersionArgument = '--version' } @{ Name = 'Python launcher'; Command = 'py'; VersionArgument = '--version' } @{ Name = 'Python manager'; Command = 'pymanager'; VersionArgument = '--version' } @{ Name = 'uv'; Command = 'uv'; VersionArgument = '--version' } @{ Name = 'pip'; Command = 'pip'; VersionArgument = '--version' } @{ Name = 'pipx'; Command = 'pipx'; VersionArgument = '--version' } @{ Name = '.NET SDK'; Command = 'dotnet'; VersionArgument = '--version' } @{ Name = 'rustup'; Command = 'rustup'; VersionArgument = '--version' } @{ Name = 'GitHub CLI'; Command = 'gh'; VersionArgument = '--version' } @{ Name = 'WSL'; Command = 'wsl'; VersionArgument = $null } ) } foreach ($tool in $Catalogue) { $resolved = @(Get-Command $tool.Command -CommandType Application -ErrorAction SilentlyContinue) $places = @($resolved | ForEach-Object { Split-Path $_.Source -Parent } | Where-Object { $_ } | Sort-Object -Unique) if (-not $resolved.Count) { [pscustomobject]@{ Name = $tool.Name Command = $tool.Command Present = $false Version = $null Owner = $null Copies = 0 Places = @() } continue } # Scoop and WSL are left without a version argument on purpose. scoop is # a PowerShell shim whose --version runs a git describe against its own # repository, and wsl --version writes UTF-16 that arrives as spaced-out # characters.
