################################################################################ <# .SYNOPSIS Validates dependency usage across GenXdev modules to ensure proper module hierarchy is maintained. .DESCRIPTION This function analyzes GenXdev modules to ensure they follow the correct dependency hierarchy. It checks that modules only reference dependencies that are listed in their RequiredModules manifest, and prevents circular dependencies by validating that modules don't reference modules that come later in the dependency chain. .PARAMETER ModuleName Filter to apply to module names. Must match GenXdev naming pattern. Defaults to checking all GenXdev modules. .PARAMETER FromScripts Search in script files instead of module files. .EXAMPLE Assert-GenXdevDependencyUsage -ModuleName "GenXdev.Coding" .EXAMPLE checkgenxdevdependencies "GenXdev*" -FromScripts #> function Assert-GenXdevDependencyUsage { [CmdletBinding()] [Alias('checkgenxdevdependencies')] param( ############################################################################### [Parameter( Mandatory = $false, Position = 1, ValueFromPipeline = $true, ValueFromPipelineByPropertyName = $true, HelpMessage = 'Filter to apply to module names' )] [ValidateNotNullOrEmpty()] [ValidatePattern('^(GenXdev|GenXde[v]\*|GenXdev(\.\w+)+)+$')] [SupportsWildcards()] [string[]] $ModuleName = @('GenXdev*'), ############################################################################### [Parameter( Mandatory = $false, HelpMessage = 'Search in script files instead of module files' )] [switch] $FromScripts ############################################################################### ) begin { # retrieve ordered list of all genxdev modules by dependency hierarchy $dependencies = @(GenXdev.Coding\Get-GenXDevNewModulesInOrderOfDependency | Microsoft.PowerShell.Core\ForEach-Object ModuleName) + @('GenXdev.Local') } process { # temporarily disabled functionality - early return return;
