well, umm, gosh, now i feel quite silly. that was easy. okay that's done.
next: i'd like to redirect the output of any "print" statements to my C
function:
> void Log(const unsigned char *utf8_cstrP);
on the mac, python output sys.stdout goes into the debug console if you're in
the debugger, and to the "console app" if not. On windows, i don't think it
goes anywhere at all?
So: i really want it to go to my own log file (via my Log() function). now,
can i specify "please output to this FILE*" ?, i looked at all the python c
headers but found nothing about redirecting the output.
I see "PySys_GetFile()" which will get what it points to, but what i want is a
"PySys_SetFile()" so i can set it.
the only alternative seems to be:
> PyObject *logObjectP = create ???;
>
> ERR(PySys_SetObject("stdout", logObjectP));
if that's the only way, how to create the logObjectP such that it redirects the
write() python function to my Log() C function?
i tried this:
--------------------------------
const char *s_printFunc =
"import sys\n"
"class CustomPrint():\n"
" def __init__(self):\n"
" self.old_stdout=sys.stdout\n"
"\n"
" def write(self, text):\n"
" self.old_stdout.write('foobar')\n"
" text = text.rstrip()\n"
" if len(text) == 0:\n"
" return\n"
" self.old_stdout.write('custom Print--->' + text +
'\n')\n";
OSStatus CPython_PreAlloc(const char *utf8Z)
{
OSStatus err = noErr;
PyCompilerFlags flags;
PyObject *logObjectP = NULL;
Py_SetProgramName(const_cast<char *>(utf8Z));
Py_Initialize();
flags.cf_flags = PyCF_SOURCE_IS_UTF8;
logObjectP = Py_CompileStringFlags(s_printFunc,
"CustomPrint", Py_single_input, &flags);
ERR_NULL(logObjectP, tsmUnsupScriptLanguageErr);
if (!err) {
ERR(PySys_SetObject("stdout", logObjectP));
ERR(PySys_SetObject("stderr", logObjectP));
Py_DECREF(logObjectP);
}
return err;
}
void CPython_PostDispose()
{
Py_Finalize();
}
void CPython_Test()
{
PyRun_SimpleString(
"from time import time, ctime\n"
"print 'Today is', ctime(time())\n");
}
-----------------------------------------
and when i run CPython_Test(), there is no output at all. If i comment out the
entire Py_CompileStringFlags() line, then the output works fine (going to
stdout as expected), so i'm not sure what i'm doing wrong
