PyRun_InteractiveOne from string?
Hi,
I hope I'm asking this in the right place... I've embedded Python in an application, and I'm now trying to emulate a "console" for immediate commands. I can see PyRun_InteractiveOneFlags and the variants are used to send single statements, but there doesn't seem to be any variants that take a string, only a FILE*. I'm in a windows app, so there's no console. (I actually have effectively two text boxes, one multi-line read only for stdout/stderr, and one input.), I know the prompt would be in the wrong place, but that's no biggie.
PyRun_String does almost what I want, except that it fails on multiline statements (if ... : etc).
I just wanted to check if there's an API I've missed, or, whether anyone can recommend an approach.
I think I could either: a) Emulate the console through an FILE* - not sure quite how this works in Windows, but I'm sure it's possible b) Copy what PyRun_InteractiveOneFlags() does, just replacing the PyParser_ASTFromFile with PyParser_ASTFromString. Only problem here is that I seem to need mod_ty, and not sure whether it's a good idea to use something that looks like an internal type.
Many thanks for any comments.

In blender 2.5 we have an interactive console with multi-line support and auto complete. Demo of using the console http://sites.google.com/site/satishgoda/blender/learningblender25/introducti...
Heres the script which interfaces python and blenders generic console api, look at how it uses the 'code' module. http://www.google.com/codesearch/p?hl=en#J_CGftyjihw/release/scripts/op/console_python.py&q=console_python&sa=N&cd=1&ct=rc
We do our own line editing functionality but basically you can use the code module like this import code namespace = {'__builtins__': __builtins__} code.InteractiveConsole(namespace) is_multiline = console.push(line_exec) # <--- this is the line you need to run in a loop and give user input to.
even though you mention not having a console, for the record that can be done like this... PyRun_String("__import__('code').interact()", Py_eval_input, namespace, namespace);
