function Read-PsfConfigPersisted { <# .SYNOPSIS Reads configurations from persisted file / registry. .DESCRIPTION Reads configurations from persisted file / registry. .PARAMETER Scope Where to read from. .PARAMETER Module Load module specific data. Use this to load on-demand configuration only when the module is imported. Useful when using the config system as cache. .PARAMETER ModuleVersion The configuration version of the module-settings to load. .PARAMETER Hashtable Rather than returning results, insert them into this hashtable. .PARAMETER Default When inserting into a hashtable, existing values are overwritten by default. Enabling this setting will cause it to only insert values if the key does not exist yet. .EXAMPLE Read-PsfConfigPersisted -Scope 127 Read all persisted default configuration items in the default mandated order. #> [OutputType([System.Collections.Hashtable])] [CmdletBinding()] Param ( [PSFramework.Configuration.ConfigScope] $Scope, [string] $Module, [int] $ModuleVersion = 1, [System.Collections.Hashtable] $Hashtable, [switch] $Default ) begin { #region Helper Functions function New-ConfigItem { [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSUseShouldProcessForStateChangingFunctions", "")] [CmdletBinding()] param ( $FullName, $Value, $Type, [switch] $KeepPersisted, [switch] $Enforced, [switch] $Policy ) [pscustomobject]@{ FullName = $FullName Value = $Value Type = $Type KeepPersisted = $KeepPersisted Enforced = $Enforced Policy = $Policy } } function Read-Registry { [CmdletBinding()] param ( $Path, [switch] $Enforced ) if (-not (Test-Path $Path)) { return } $common = 'PSPath', 'PSParentPath', 'PSChildName', 'PSDrive', 'PSProvider' foreach ($item in ((Get-ItemProperty -Path $Path -ErrorAction Ignore).PSObject.Properties | Where-Object Name -NotIn $common)) { if ($item.Value -like "Object:*") { $data = $item.Value.Split(":", 2) New-ConfigItem -FullName $item.Name -Type $data[0] -Value $data[1] -KeepPersisted -Enforced:$Enforced -Policy } else { try { New-ConfigItem -FullName $item.Name -Value ([PSFramework.Configuration.ConfigurationHost]::ConvertFromPersistedValue($item.Value)) -Policy } catch { Write-PSFMessage -Level Warning -Message "Failed to load configuration from Registry: $($item.Name)" -ErrorRecord $_ -Target "$Path : $($item.Name)" } } } } #endregion Helper Functions if (-not $Hashtable) { $results = @{ } } else { $results = $Hashtable } if ($Module) { $filename = "$($Module.ToLower())-$($ModuleVersion).json" } else { $filename = "psf_config.json" } } process { #region File - Computer Wide if ($Scope -band 64) { foreach ($item in (Read-PsfConfigFile -Path (Join-Path $script:path_FileSystem $filename))) { if (-not $Default) { $results[$item.FullName] = $item } elseif (-not $results.ContainsKey($item.FullName)) { $results[$item.FullName] = $item } } } #endregion File - Computer Wide #region Registry - Computer Wide if (($Scope -band 4) -and (-not $script:NoRegistry)) { foreach ($item in (Read-Registry -Path $script:path_RegistryMachineDefault)) { if (-not $Default) { $results[$item.FullName] = $item } elseif (-not $results.ContainsKey($item.FullName)) { $results[$item.FullName] = $item } } } #endregion Registry - Computer Wide #region File - User Shared if ($Scope -band 32) { foreach ($item in (Read-PsfConfigFile -Path (Join-Path $script:path_FileUserShared $filename))) { if (-not $Default) { $results[$item.FullName] = $item } elseif (-not $results.ContainsKey($item.FullName)) { $results[$item.FullName] = $item } } } #endregion File - User Shared #region Registry - User Shared if (($Scope -band 1) -and (-not $script:NoRegistry)) { foreach ($item in (Read-Registry -Path $script:path_RegistryUserDefault)) { if (-not $Default) { $results[$item.FullName] = $item } elseif (-not $results.ContainsKey($item.FullName)) { $results[$item.FullName] = $item } } } #endregion Registry - User Shared #region File - User Local if ($Scope -band 16) { foreach ($item in (Read-PsfConfigFile -Path (Join-Path $script:path_FileUserLocal $filename))) { if (-not $Default) { $results[$item.FullName] = $item } elseif (-not $results.ContainsKey($item.FullName)) { $results[$item.FullName] = $item } } } #endregion File - User Local #region Registry - User Enforced if (($Scope -band 2) -and (-not $script:NoRegistry)) { foreach ($item in (Read-Registry -Path $script:path_RegistryUserEnforced -Enforced)) { if (-not $Default) { $results[$item.FullName] = $item } elseif (-not $results.ContainsKey($item.FullName)) { $results[$item.FullName] = $item } } } #endregion Registry - User Enforced #region Registry - System Enforced if (($Scope -band 8) -and (-not $script:NoRegistry)) { foreach ($item in (Read-Registry -Path $script:path_RegistryMachineEnforced -Enforced)) { if (-not $Default) { $results[$item.FullName] = $item } elseif (-not $results.ContainsKey($item.FullName)) { $results[$item.FullName] = $item } } } #endregion Registry - System Enforced } end { $results } } |
