function Install-PSFLoggingProvider { <# .SYNOPSIS Installs a logging provider for the PSFramework. .DESCRIPTION This command installs a logging provider registered with the PSFramework. Some providers may require special installation steps, that cannot be handled by the common initialization / configuration. For example, a provider may require installation of binaries that require elevation. In order to cover those scenarios, a provider can include an installation script, which is called by this function. It can also provide additional parameters to this command, which are dynamically provided once the -Name parameter has been passed. When registering the logging provider (Using Register-PSFLoggingProvider), you can specify the logic executed by this command with these parameters: - IsInstalledScript : Must return $true when installation has already been performed. If this returns not $false, then this command will do nothing at all. - InstallationScript : The script performing the actual installation - InstallationParameters : A script that returns dynamic parameters. This can be used to generate additional parameters that can modify the installation process. NOTE: This module does not contain help/guidance on how to generate dynamic parameters! .PARAMETER Name The name of the provider to install .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:\> Install-PSFLoggingProvider -Name Eventlog Installs a logging provider named 'eventlog' #> [CmdletBinding()] Param ( [Alias('Provider', 'ProviderName')] [string] $Name, [switch] $EnableException ) dynamicparam { if ($Name -and ([PSFramework.Logging.ProviderHost]::Providers.ContainsKey($Name.ToLower()))) { [PSFramework.Logging.ProviderHost]::Providers[$Name.ToLower()].InstallationParameters.Invoke() } } begin { } process { if (Test-PSFFunctionInterrupt) { return } if (-not ([PSFramework.Logging.ProviderHost]::Providers.ContainsKey($Name.ToLower()))) { Stop-PSFFunction -Message "Provider $Name not found!" -EnableException $EnableException -Category InvalidArgument -Target $Name -Tag 'logging', 'provider', 'install' -Depth 1 return } $provider = [PSFramework.Logging.ProviderHost]::Providers[$Name.ToLower()] if (-not ([System.Management.Automation.ScriptBlock]::Create($provider.IsInstalledScript).Invoke())) { try { [System.Management.Automation.ScriptBlock]::Create($provider.InstallationScript).Invoke() } catch { Stop-PSFFunction -Message "Failed to install provider '$Name'" -EnableException $EnableException -Target $Name -ErrorRecord $_ -Tag 'logging', 'provider', 'install' -Depth 1 return } } } end { if (Test-PSFFunctionInterrupt) { return } } } |
