function Get-Dependency { <# .SYNOPSIS Read a dependency psd1 file .DESCRIPTION Read a dependency psd1 file The resulting object contains these properties DependencyFile : Path to psd1 file this dependency is defined in DependencyName : Unique dependency name (the key in the psd1 file). We reserve PSDependOptions for global options. DependencyType : Type of dependency. See Get-PSDependType Name : Name for the dependency Version : Version for the dependency Parameters : Hash table of parameters to pass to dependency script Source : Source for the dependency Target : Target for the dependency AddToPath : If specified and dependency type supports it, add dependency to path (e.g. a module is added to PSModulePath) Tags : One or more tags to categorize or filter dependencies DependsOn : Dependency that must be installed before this PreScripts : One or more paths to PowerShell scripts to run before the dependency PostScripts : One or more paths to PowerShell scripts to run after the dependency PSDependOptions: Hash table of global PSDepend options Raw : Raw output for this dependency from the PSD1. May include data outside of standard items above. These are parsed from dependency PSD1 files as follows: Simple syntax: @{ DependencyName = 'Version' } With the simple syntax: * The DependencyName (key) is used as the Name * We default to Git as the DependencyType if we see a '/', otherwise we default to PSGalleryModule * The Version (value) is a string, and is used as the Version * Other properties are set to $null Advanced syntax: @{ DependencyName = @{ DependencyType = 'TypeOfDependency'. # See Get-PSDependType Name = 'NameForThisDependency' Version = '0.1.0' Parameters = @{ Example = 'Value' } # Optional parameters for the dependency script. Source = 'Some source' # Usually optional Target = 'Some target' # Usually optional AddToPath = $True # Whether to add new dependency to path, if dependency type supports it. Tags = 'prod', 'local' # One or more tags to categorize or filter dependencies DependsOn = 'Some_Other_DependencyName' # DependencyName that must run before this PreScripts = 'C:\script.ps1' # Script(s) to run before this dependency PostScripts = 'C:\script2.ps1' # Script(s) to run after this dependency } } Global options: @{ PSDependOptions = @{ Target = 'C:\temp' } # Supported for: # Parameters # Source # Target # AddToPath # Tags # DependsOn # PreScripts # PostScripts # Dependencies use these values as a default, unless you specify them explicitly for a dependency } Note that you can mix these syntax together in the same psd1. .PARAMETER Path Path to project root or dependency file. If a folder is specified, we search for and process *.depend.psd1 and requirements.psd1 files. .PARAMETER Tags Limit results to one or more tags defined in the Dependencies .PARAMETER Recurse If specified and path is a container, search for *.depend.psd1 and requirements.psd1 files recursively under $Path .LINK about_PSDepend .LINK about_PSDepend_Definitions .LINK Get-PSDependScript .LINK Get-PSDependType .LINK Install-Dependency .LINK Invoke-PSDepend .LINK https://github.com/RamblingCookieMonster/PSDepend #> [cmdletbinding()] param( [string[]]$Path = $PWD.Path, [string[]]$Tags, [switch]$Recurse ) # Helper to pick from global psdependoptions, or return a default function Get-GlobalOption { param( $Options = $PSDependOptions, $Name, $Prefer, $Default = $Null ) # Check for preferred value, otherwise try to get value from key, otherwise use default.... if($Prefer){ return $Prefer} try { return $Options[$Name] } catch { } return $Default } foreach($DependencyPath in $Path) { #Resolve relative paths...
