function Import-PSFConfig { <# .SYNOPSIS Imports a json configuration file into the configuration system. .DESCRIPTION Imports a json configuration file into the configuration system. .PARAMETER Path The path to the json file to import. .PARAMETER ModuleName Import configuration items specific to a module from the default configuration paths. .PARAMETER ModuleVersion The configuration version of the module-settings to load. .PARAMETER Scope Where to import the module specific configuration items form. Only file-based scopes are supported for this. By default, all locations are queried, with user settings beating system settings. .PARAMETER IncludeFilter If specified, only elements with names that are similar (-like) to names in this list will be imported. .PARAMETER ExcludeFilter Elements that are similar (-like) to names in this list will not be imported. .PARAMETER Peek Rather than applying the setting, return the configuration items that would have been applied. .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. .EXAMPLE PS C:\> Import-PSFConfig -Path '.\config.json' Imports the configuration stored in '.\config.json' .EXAMPLE PS C:\> Import-PSFConfig -ModuleName mymodule Imports all the module specific settings that have been persisted in any of the default file system paths. #> [Diagnostics.CodeAnalysis.SuppressMessageAttribute("PSAvoidUsingEmptyCatchBlock", "")] [CmdletBinding(DefaultParameterSetName = "Path", HelpUri = 'https://psframework.org/documentation/commands/PSFramework/Import-PSFConfig')] param ( [Parameter(Mandatory = $true, ValueFromPipeline = $true, ParameterSetName = "Path")] [string[]] $Path, [Parameter(ParameterSetName = "ModuleName", Mandatory = $true)] [string] $ModuleName, [Parameter(ParameterSetName = "ModuleName")] [int] $ModuleVersion = 1, [Parameter(ParameterSetName = "ModuleName")] [PSFramework.Configuration.ConfigScope] $Scope = "FileUserLocal, FileUserShared, FileSystem", [Parameter(ParameterSetName = "Path")] [string[]] $IncludeFilter, [Parameter(ParameterSetName = "Path")] [string[]] $ExcludeFilter, [Parameter(ParameterSetName = "Path")] [switch] $Peek, [switch] $EnableException ) begin { Write-PSFMessage -Level InternalComment -Message "Bound parameters: $($PSBoundParameters.Keys -join ", ")" -Tag 'debug','start','param' } process { #region Explicit Path foreach ($item in $Path) { try { if ($item -like "http*") { $data = Read-PsfConfigFile -Weblink $item -ErrorAction Stop } else { $pathItem = $null try { $pathItem = Resolve-PSFPath -Path $item -SingleItem -Provider FileSystem } catch { } if ($pathItem) { $data = Read-PsfConfigFile -Path $pathItem -ErrorAction Stop } else { $data = Read-PsfConfigFile -RawJson $item -ErrorAction Stop } } } catch { Stop-PSFFunction -Message "Failed to import $item" -EnableException $EnableException -Tag 'fail', 'import' -ErrorRecord $_ -Continue -Target $item } :element foreach ($element in $data) { #region Exclude Filter foreach ($exclusion in $ExcludeFilter) { if ($element.FullName -like $exclusion) { continue element } } #endregion Exclude Filter #region Include Filter if ($IncludeFilter) { $isIncluded = $false foreach ($inclusion in $IncludeFilter) { if ($element.FullName -like $inclusion) { $isIncluded = $true break } } if (-not $isIncluded) { continue } } #endregion Include Filter if ($Peek) { $element } else { try { if (-not $element.KeepPersisted) { Set-PSFConfig -FullName $element.FullName -Value $element.Value -EnableException } else { Set-PSFConfig -FullName $element.FullName -PersistedValue $element.Value -PersistedType $element.Type } } catch { Stop-PSFFunction -Message "Failed to set '$($element.FullName)'" -ErrorRecord $_ -EnableException $EnableException -Tag 'fail', 'import' -Continue -Target $item } } } } #endregion Explicit Path if ($ModuleName) { $data = Read-PsfConfigPersisted -Module $ModuleName -Scope $Scope -ModuleVersion $ModuleVersion foreach ($value in $data.Values) { if (-not $value.KeepPersisted) { Set-PSFConfig -FullName $value.FullName -Value $value.Value -EnableException:$EnableException} else { Set-PSFConfig -FullName $value.FullName -Value ([PSFramework.Configuration.ConfigurationHost]::ConvertFromPersistedValue($value.Value, $value.Type)) -EnableException:$EnableException } } } } end { } } |
