[IronPython] DLR: ScriptIO Readonly on ScriptRuntime

[Ben Hall]

Hello,

I'm currently playing around with some code involing the ScriptRuntime
and executing code blocks of code.  What I want, is to be able to
redirect the output from the script. For example, if a user types
Print 'Hello World' I want it to be redirected to my outputting
stream.

To start with, I looked at the hosting spec.  On the ScriptRuntime
class, it says there are InputStreams, OutputStreams and ErrorStreams
(pg 30) - great, just want I want!
http://compilerlab.members.winisp.net/dlr-spec-hosting.pdf

However, looking at Assembly: Microsoft.Scripting.Core,
Version=1.0.0.2000, ScriptRuntime does not have these properties.

It does however have a ScriptIO property for the ScriptIO class which
contains all of the streams nicely encapsulated. However, this
variable is readonly and only has a getter on the property. Is there
any reason for this? What is the recommended approach now in order to
get access to the output?  I was hoping I would be able to create my
own ScriptIO class and assign this to the engine.

Any advice on this would be great!

Thanks
