I'm using the following code to embed Powershell into IronPython. I hope to
eventually replace almost all of my (large) Powershell script with
IronPython.
from System.Management.Automation.Runspaces import RunspaceFactory
the_runspace = RunspaceFactory.CreateRunspace()
the_runspace.Open()
ri = RunspaceInvoke(the_runspace)
out = ri.Invoke('. .\myscript.ps1')
I'm able to pass variables back and forth using
the_runspace.SessionStateProxy.Get/SetVariable, which is really cool.
My problem is that any calls to Write-Host fail with "Cannot invoke this
function becasue the current host does not implement it." Of course I can
remove all the Write-Host's, but I really depend on them for status
information about how my script is running, and not having access to console
output makes my script much harder to debug.

says
"To get around this, you can remove *write-host* from your scripts and just
have them write single lines, or you can implement a simple *PSHost* (although
this is a bit harder than it sounds)."
What does "just have them write single lines mean?" Any pointers on how I
can get this working under IronPython?
Thanks,
Steve
