Hello guys,
I'm trying to do some simple examples of hosting with IronPython 2. Boy
you made things more complicated than IronPython 1. :-)
Unfortunately the DLR hosting spec document is out of date. I have a
couple of questions (but will keep exploring).
The simplest use case is just to evaluate an expression and return a result.
The hosting spec document mention 'ScriptRuntime.Execute(text)'. This
may or may not be the right way to evaluate an expression, but in any
case it has been removed.
An alternative is:
engine = PythonEngine.CurrentEngine # a ScriptEngine
unit = engine.CreateSourceUnitFromString(code, id)
result = unit.Execute()
Which is straightforward enough, however I can't see a way to set
TrueDivision using this technique. (What is the 'id' by the way?)
I can see that TrueDivision is a setting on
IronPython.Runtime.ModuleOptions and IronPython.Runtime.PythonModule.
Can I set this on the engine somehow?
All the alternative seem to lead down a rabbit warren of 'create this
object - which requires this object - which you construct from another
object - which...'. I don't know which path to follow down the rabbit
hole...
:-)
Any suggestions to save me from madness?
Michael
