<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I’ve been experimenting with a Python console control
for WPF. The improvements made for IronPython beta 8 make this a lot easier
thanks to several new functions on the PythonEngine: ExecuteToConsole, FormatException
and ParseInteractiveInput.<o:p></o:p></span></font></p>

font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>One of the things I need to do to communicate with a C#
application is to change the default encoding to receive non-ascii characters. For
this I execute several commands after the PythonEngine instance is created.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Setting the default encoding seems like a good candidate for
the options you can pass to the engine while creating a new instance. It would
also be easier if I could get at the options through a PythonEngine instance.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I hope you’re not going to remove the FilterStackFrame
delegate from the FormatException method as the comment seems to indicate. I
think it’s very useful to filter my own C# application from the stack
trace. Maybe you could add an overload with just the Exception and
FilterStackFrame?<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>To set a variable in the PythonEngine you need to use SetGlobal
with a SymbolId. Am I correct to use SymbolTable.StringToId(name) to generate a
SymbolId? It used to be easier with just a string to specify the name.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>A useful enhancement for the PythonEngine might be if there
was a way to directly call a Python function loaded in the engine and pass
parameters to it and get the return value. You could also support out
parameters similar to calling a method through reflection.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>If you want to specify that a number is a long you can write
10L. Is there a way to specify that a number is a double or a decimal?<o:p></o:p></span></font></p>
