PS (2) ISE Transcript

The PowerShell 2.0 ISE throws a "NotImplemented: (:) [Start-Transcript], PSNotSupportedException" exception.


I would have expected that the Transcript would be implemented outside the Host and call both an Add-Content and a Write-Host.  I wonder what could have been intended for the Host to use the output from that couldn't be done by a handler in the Write-Host. 


So when calling in production scheduler of powershell.exe the transcripts are fine.  When I run in the ISE, it doesn't work so well.  Of course all of the output is visible on the OutputPane, but the red exception text and lack of per run detail left me unfulfilled.


...Now is there a way to clobber the default  stop-transcript then call the original.




try {
    Start-Transcript -Path "C:\Transcript.txt" -Append 
} catch {
    clear # only want this run to output.
 } 



#profile function
# Todo:  Check Verb
Function  Export-ISEOutputToWindow
{
 $transcriptHeader = @"

    $Outfile = $psise.CurrentPowerShellTab.Files.Add(); 
    $Outfile.Editor.Text = $transcriptHeader + $psise.CurrentPowerShellTab.OutPut.Text;
}

#For use
try {
    stop-transcript ;
} catch { 
  Export-ISEOutputToWindow;
}

Will suggested that I look at http://blogs.technet.com/b/heyscriptingguy/archive/2010/09/25/create-a-transcript-of-commands-from-the-windows-powershell-ise.aspx.  This had a ISETranscript that pulled the detail from the output pane.  I combined this with a function I saw yesterday on poshcode that implemented an Out-ISEFileTab process.  Combined they make the above.
