Subject: [capi-sig] set default encoding in C program
Message-ID: <4C0853CE.2030101@mozapps.org>

I have to have Unicode strings in my program. Trying to set the default 
encoding to utf-8 is a pain. (another *RANT*).

the way i was thinking about doing it is create a sitecustomization.py  
in the directory that the executable is in.  That does not work. I can 
not change site.py or sitecustomization.py.

How do you set the default encoding to 'utf-8'?

Could you set the environment variable in C before initializing python?

You don't change it.  You wish it didn't exist and explicitly decode
when data enters or leaves your program.

What I suspect you're doing is creating unicode constants from C, so
you're working from a UTF-8 encoded source file.  I believe
PyUnicode_DecodeUTF8() is your best bet there, even if you do have to
explicitly pass the size.  If you're not dealing with constants then
it's not a big deal, and in fact you want an explicit size (as NUL
does NOT indicate end of string.)

Next problems, (and hope last)

I have started some Python threads, and want to wait for them to finish.

I wrote this program to demonstrate my problem. I am on a 64 bit

I tried playing around with GIL state but it does not change anything, 
so it is commented out.

when using pthreads it works (of course)
when I use python threads the sleep does not work and the threads all 
exit on the _join

Message-ID: <AANLkTimYDM_6nGAMbsa0lI-FcHv1TOM-sYnD_Hwf8egA@mail.gmail.com>

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.

Dave.

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/introduction-to-blender-python-api

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);

Thanks so much.. that looks like exactly what I want to do.  Looks like
you've done a fantastic job on the integration there - makes my weedy little
console look very plain :)

Just need to work out why boost::python won't exec code.InteractiveConsole()
now :)

Thanks again.
Dave.

Hi,

I am trying to figure out, what files to copy with my app so I am able to initialize the python runtime.
Where can I find information about this?

Thank you,

This should get you started:

http://docs.python.org/extending/embedding.html

Apart from the C runtime, you'll also need to ship the Python stdlib,
e.g. in a ZIP file.

I should have mentioned the console I linked to is not thread safe, I
asked in #python about this and apparently there are 2 ways to work
around this.
- use a context manager to work out which thread is taking to the
overridden stdout.
- override print() not to use sys.stdout, since the consoles "write"
function can already redirect exception output.

Id like to make this thread safe but for now its not a priority for me.

>From the script I linked this looks like its done entirely in python,
this is because we have a py/c api so python has access to the command
line and can add output to the display, rather then having C call
python directly but both ways can work.

Thanks for this.  It's working perfectly now.  Funnily enough threading was
the next thing on the list, so the (non-console) scripts run in a separate
thread, allowing them to be stopped by the UI.  You don't happen to know if
PyErr_SetString is thread safe, to "break" the currently running script?

I'll have to think about whether taking care of separate threads redirecting
sys.stdout is important - I'm not sure that it is in our environment.

Cheers,
Dave.
