I was working in ISE pretty much during last two days (oh yes, was nice end of 2011 and beginning of 2012). During script creation I was checking values of variables frequently. Wouldn’t be nice to see variables value and not just write it’s name to Command Pane? So I came with another menu Add-on command.

function GetValues
{
    $content = $psISE.CurrentFile.Editor.Text
    $tokens = [System.Management.Automation.PsParser]::Tokenize($content, [ref] $null) |? {$_.Type -eq 'Variable'} | Sort Content -Unique

    foreach ($t in $tokens)
    {
        $prop = @{
            Name = $t.Content
            Value = Get-Variable -Name $($t.Content) -ValueOnly -ErrorAction SilentlyContinue
        }

        New-Object -TypeName PSObject -Property $prop | Select Name, Value
    }
}

$psISE.CurrentPowerShellTab.AddOnsMenu.Submenus.Add('Show values',{GetValues},'CTRL+SHIFT+V') | Out-Null

When you work with any script, you can run it and will see all actual script variables in Output Pane.

Variables in current script

Using Tokenizer API I received all variables from current script and created new object with variable name and value. Then it’s send to output. I am thinking about some graphical output (WPF or ShowUI) or just to Out-GridView. There are also some another points to update but for my current needs it’s OK.
