A very simple function to retrieve the Set-StrictMode setting of the user session. .DESCRIPTION Retrieve the Set-StrictMode setting for the current session. This procedure is necessary as there is, apparently, no equivalent PowerShell variable for this and it enables the setting to be returned to its original state after possibly being changed within a script. Add this function to your $profile. .EXAMPLE Get-StrictMode The various values returned will be Version 1, Version 2, or Off. .EXAMPLE $a = (Get-StrictMode).Version() This will allow the environment to be restored just by entering the commmand Invoke-Expression "Set-StrictMode $a" #> function Get-StrictMode { $errorActionPreference = 'Stop' $version = '0' try { $version = '2' $z = "2 * $nil" #V2 will catch this one. $version = '1' $z = 2 * $nil #V1 will catch this. $version = 'Off' } catch { } $errorActionPreference = 'Continue' New-Module -ArgumentList $version -AsCustomObject -ScriptBlock { param ([String]$version) function Version() { if ($version -eq 'Off') { [String]$output = '-Off' } else { [String]$output = "-Version $version" } "$output" #(Get-StrictMode).Version() } function ToString() { if ($version -ne 'Off') { $version = "Version $version" } "StrictMode: $version" #Get-StrictMode will output string. } Export-ModuleMember -function Version,ToString } } |
