Function Import-Dependency { <# .SYNOPSIS Import a specific dependency .DESCRIPTION Import a specific dependency, if that dependency supports it. Takes output from Get-Dependency * Runs dependency scripts depending on each dependencies type. * Imports items if supported See Get-Help about_PSDepend for more information. .PARAMETER Dependency Dependency object from Get-Dependency. .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 Tags Only test dependencies that are tagged with all of the specified Tags (-and, not -or) .EXAMPLE Get-Dependency -Path C:\requirements.psd1 | Import-Dependency Get dependencies from C:\requirements.psd1 and import them .LINK about_PSDepend .LINK about_PSDepend_Definitions .LINK Get-Dependency .LINK Get-PSDependType .LINK Invoke-PSDepend .LINK https://github.com/RamblingCookieMonster/PSDepend #> [cmdletbinding()] Param( [parameter( ValueFromPipeline = $True, ParameterSetName='Map', Mandatory = $True)] [PSTypeName('PSDepend.Dependency')] [psobject[]]$Dependency, [validatescript({Test-Path -Path $_ -PathType Leaf -ErrorAction Stop})] [string]$PSDependTypePath = $(Join-Path $ModuleRoot PSDependMap.psd1), [string[]]$Tags ) Begin { # This script reads a depend.psd1, installs dependencies as defined Write-Verbose "Running Import-Dependency with ParameterSetName '$($PSCmdlet.ParameterSetName)' and params: $($PSBoundParameters | Out-String)" } Process { Write-Verbose "Dependencies:`n$($Dependency | Out-String)" #Get definitions, and dependencies in this particular psd1 $DependencyDefs = Get-PSDependScript $TheseDependencyTypes = @( $Dependency.DependencyType | Sort-Object -Unique ) #Build up hash, we call each dependencytype script for applicable dependencies foreach($DependencyType in $TheseDependencyTypes) { $DependencyScript = $DependencyDefs.$DependencyType if(-not $DependencyScript) { Write-Error "DependencyType $DependencyType is not defined in PSDependMap.psd1" continue } $TheseDependencies = @( $Dependency | Where-Object {$_.DependencyType -eq $DependencyType}) #Define params for the script #Each dependency type can have a hashtable to splat. $RawParameters = Get-Parameter -Command $DependencyScript $ValidParamNames = $RawParameters.Name if($ValidParamNames -notcontains 'PSDependAction') { Write-Error "No PSDependAction found on PSDependScript [$DependencyScript].
