function Reset-DbatoolsConfig { <# .SYNOPSIS Reverts a configuration item to its default value. .DESCRIPTION This command can be used to revert a configuration item to the value it was initialized with. Generally, this amounts to reverting it to its default value. In order for a reset to be possible, two conditions must be met: - The setting must have been initialized. - The setting cannot have been enforced by policy. .PARAMETER ConfigurationItem A configuration object as returned by Get-DbatoolsConfig. .PARAMETER FullName The full name of the setting to reset, offering the maximum of precision. .PARAMETER Module The name of the module, from which configurations should be reset. Used in conjunction with the -Name parameter to filter a specific set of items. .PARAMETER Name Used in conjunction with the -Module parameter to select which settings to reset using wildcard comparison. .PARAMETER EnableException This parameters disables user-friendly warnings and enables the throwing of exceptions. This is less user friendly, but allows catching exceptions in calling scripts. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .NOTES Tags: Module Author: Friedrich Weinmann (@FredWeinmann) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Reset-DbatoolsConfig .EXAMPLE PS C:\> Reset-DbatoolsConfig -Module MyModule Resets all configuration items of the MyModule to default. .EXAMPLE PS C:\> Get-DbatoolsConfig | Reset-DbatoolsConfig Resets ALL configuration items to default. .EXAMPLE PS C:\> Reset-DbatoolsConfig -FullName MyModule.Group.Setting1 Resets the configuration item named 'MyModule.Group.Setting1'. #> [CmdletBinding(DefaultParameterSetName = 'Pipeline', SupportsShouldProcess, ConfirmImpact = 'Low')] param ( [Parameter(ValueFromPipeline = $true, ParameterSetName = 'Pipeline')] [Sqlcollaborative.Dbatools.Configuration.Config[]] $ConfigurationItem, [Parameter(ValueFromPipeline = $true, ParameterSetName = 'Pipeline')] [string[]] $FullName, [Parameter(Mandatory = $true, ParameterSetName = 'Module')] [string] $Module, [Parameter(ParameterSetName = 'Module')] [string] $Name = "*", [switch]$EnableException ) process { #region By configuration Item foreach ($item in $ConfigurationItem) { if ($PSCmdlet.ShouldProcess($item.FullName, 'Reset to default value')) { try { $item.ResetValue() } catch { Stop-Function -Message "Failed to reset the configuration item." -ErrorRecord $_ -Continue -EnableException $EnableException } } } #endregion By configuration Item #region By FullName foreach ($nameItem in $FullName) { # The configuration items themselves can be cast to string, so they need to be filtered out, # otherwise on bind they would execute for this code-path as well. if ($nameItem -ceq "Sqlcollaborative.Dbatools.Configuration.Config") { continue } foreach ($item in (Get-DbatoolsConfig -FullName $nameItem)) { if ($PSCmdlet.ShouldProcess($item.FullName, 'Reset to default value')) { try { $item.ResetValue() } catch { Stop-Function -Message "Failed to reset the configuration item." -ErrorRecord $_ -Continue -EnableException $EnableException } } } } #endregion By FullName if ($Module) { foreach ($item in (Get-DbatoolsConfig -Module $Module -Name $Name)) { if ($PSCmdlet.ShouldProcess($item.FullName, 'Reset to default value')) { try { $item.ResetValue() } catch { Stop-Function -Message "Failed to reset the configuration item." -ErrorRecord $_ -Continue -EnableException $EnableException } } } } } } |
