</div>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>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.</span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'> </span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>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.</span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>
</span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>
import sys</span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>
sys.setdefaultencoding('utf_16_le')</span><o:p></o:p></p>

del(sys)</span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'> </span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>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.</span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'> </span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>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?</span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'> </span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>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.</span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'> </span><o:p></o:p></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>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.</span><o:p></o:p></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>If
you want to specify that a number is a long you can write 10L. Is there a way
