Function Invoke-PSDepend { <# .SYNOPSIS Invoke PSDepend .DESCRIPTION Invoke PSDepend Searches for and runs *.depend.psd1 and requirements.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 and requirements.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 .PARAMETER Test Run tests for dependencies we find. Appends a 'DependencyExists' property indicating whether the dependency exists by default Specify Quiet to simply return $true or $false depending on whether all dependencies exist .PARAMETER Quiet If specified along with Test, we return $true, or $false depending on whether all dependencies were met .PARAMETER Install Run the install for a dependency Default behavior .PARAMETER Target If specified, override the target in the PSDependOptions or Dependency. .PARAMETER Import If the dependency supports it, import it .EXAMPLE Invoke-PSDepend # Search for and run *.deploy.psd1 and requirements.psd1 files under the current path .EXAMPLE Invoke-PSDepend -Path C:\Path\To\require.psd1 # Install dependencies from require.psd1 .EXAMPLE Invoke-PSDepend -Path C:\Requirements -Recurse $False # Find and run *.depend.psd1 and requirements.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( DefaultParameterSetName = 'installimport', SupportsShouldProcess = $True, ConfirmImpact='High' )] Param( [validatescript({Test-Path -Path $_ -ErrorAction Stop})] [parameter( Position = 0, 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 = $True, [parameter(ParameterSetName = 'test')] [switch]$Test, [parameter(ParameterSetName = 'test')] [switch]$Quiet, [parameter(ParameterSetName = 'installimport')] [switch]$Import, [parameter(ParameterSetName = 'installimport')] [switch]$Install, [switch]$Force, [String]$Target ) Begin { # Build parameters $InvokeParams = @{ PSDependAction = @() PSDependTypePath = $PSDependTypePath } $DoInstall = $PSCmdlet.ParameterSetName -eq 'installimport' -and $Install $DoImport = $PSCmdlet.ParameterSetName -eq 'installimport' -and $Import $DoTest = $PSCmdlet.ParameterSetName -eq 'test' -and $Test if($DoInstall){$InvokeParams.PSDependAction += 'Install'} if($DoImport){$InvokeParams.PSDependAction += 'Import'} if($DoTest){$InvokeParams.PSDependAction += 'Test'} if($InvokeParams.PSDependAction.count -like 0) { $InvokeParams.PSDependAction += 'Install' } Write-Verbose "Running Invoke-PSDepend with ParameterSetName '$($PSCmdlet.ParameterSetName)', PSDependAction $($InvokeParams.PSDependAction), and params: $($PSBoundParameters | Out-String)" $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) } # Handle Dependencies $Dependencies = Get-Dependency @GetPSDependParams if($DoTest -and $Quiet) { $TestResult = [System.Collections.ArrayList]@() } #TODO: Add ShouldProcess here if install is specified... foreach($Dependency in $Dependencies) { if($PSBoundParameters.ContainsKey('Target')) { Write-Verbose "Overriding Dependency target [$($Dependency.Target)] with target parameter value [$Target]" $Dependency.Target = $Target } if( ($Force -and -not $WhatIf) -or ($DoTest) -or $PSCmdlet.ShouldProcess( "Processed the dependency '$($Dependency.DependencyName -join ", ")'", "Process the dependency '$($Dependency.DependencyName -join ", ")'?", "Processing dependency" )) { $PreScriptSuccess = $True #anti pattern!
