Function Invoke-PSDepend { <# .SYNOPSIS Invoke PSDepend .DESCRIPTION Invoke PSDepend Searches for and runs *.depend.psd1 files in the current and nested paths See Get-Help about_PSDepend for more information. .PARAMETER Path Path to a specific depend.psd1 file, or to a folder that we recursively search for *.depend.psd1 files Defaults to the current path .PARAMETER Recurse If path is a folder, whether to recursively search for *.depend.psd1 files under that folder Defaults to $True .PARAMETER Tags Only invoke dependencies that are tagged with all of the specified Tags (-and, not -or) .PARAMETER PSDependTypePath Specify a PSDependMap.psd1 file that maps DependencyTypes to their scripts. This defaults to the PSDependMap.psd1 in the PSDepend module folder .PARAMETER Force Force dependency, skipping prompts and confirmation .EXAMPLE Invoke-PSDepend # Search for and run *.deploy.psd1 files under the current path .EXAMPLE Invoke-PSDepend -Path C:\Path\To\requirements.psd1 # Install dependencies from requirements.psd1 .EXAMPLE Invoke-PSDepend -Path C:\Requirements -Recurse $False # Find and run *.depend.psd1 files under C\Requirements (but not subfolders) .LINK about_PSDepend .LINK about_PSDepend_Definitions .LINK Get-Dependency .LINK Install-Dependency .LINK https://github.com/RamblingCookieMonster/PSDepend #> [cmdletbinding( SupportsShouldProcess = $True, ConfirmImpact='High' )] Param( [validatescript({Test-Path -Path $_ -ErrorAction Stop})] [parameter( ValueFromPipeline = $True, ValueFromPipelineByPropertyName = $True)] [string[]]$Path = '.', [validatescript({Test-Path -Path $_ -PathType Leaf -ErrorAction Stop})] [string]$PSDependTypePath = $(Join-Path $ModuleRoot PSDependMap.psd1), [string[]]$Tags, [bool]$Recurse = $True, [switch]$Force ) Begin { # This script reads a depend.psd1, deploys files or folders as defined Write-Verbose "Running Invoke-PSDepend with ParameterSetName '$($PSCmdlet.ParameterSetName)' and params: $($PSBoundParameters | Out-String)" $RejectAll = $false $ConfirmAll = $false # Do we want force? $InvokeParams = @{} if($Force) { $InvokeParams.Add('Force', $Force) } $DependencyFiles = New-Object System.Collections.ArrayList } Process { foreach( $PathItem in $Path ) { # Create a map for dependencies [void]$DependencyFiles.AddRange( @( Resolve-DependScripts -Path $PathItem -Recurse $Recurse ) ) if ($DependencyFiles.count -gt 0) { Write-Verbose "Working with [$($DependencyFiles.Count)] dependency files from [$PathItem]:`n$($DependencyFiles | Out-String)" } else { Write-Warning "No *.depend.ps1 files found under [$PathItem]" } } # Parse $GetPSDependParams = @{Path = $DependencyFiles} if($PSBoundParameters.ContainsKey('Tags')) { $GetPSDependParams.Add('Tags',$Tags) } $DependencyScripts = Get-PSDependScript # Handle Dependencies $ToInstall = Get-Dependency @GetPSDependParams #TODO: Add ShouldProcess here.
