Embed python

[Andre Smit]

Simple example using pbcc shown below. Make sure your exe can see the python25.dll. I'm having a problem with raw_input that doesn't allow input. Any suggestions?

#DIM ALL
DECLARE SUB   pyIni LIB "python25.dll" ALIAS "Py_Initialize"
DECLARE SUB   pyFin LIB "python25.dll" ALIAS "Py_Finalize"
declare function pyRun lib "python25.dll" ALIAS "PyRun_SimpleString" (s as asciiz) as integer
FUNCTION PBMAIN()
 
 STDOUT "Initiate python"
 pyIni
 pyRun("print '>>> hello from python <<<'")
 pyRun("import sys")
 pyRun("print '>>> modules: <<<'")
 pyRun("print sys.builtin_module_names")
 pyRun("print '>>> module keys: <<<'")
 pyRun("print sys.modules.keys()") 
' PyRun("execfile('foo.py')")
 STDOUT "Finalize python"
 pyFin
END FUNCTION
#if 0
'Contents of foo.py
name = raw_input('What is your name?\n') # \n is a newline 
print 'Hi', name
#endif

Hi Andre,

I do not have PBCC, could try only alternative of your code in thinBASIC ... where it worked. Do you have latest Python 2.5.1 ?
Maybe you should alocate console using API and not PB default ( maybe the same, not sure ).

Do you get any error message or the console hangs waiting for input?

Listing I got:

What is your name?
[I]Petr or maybe not?[/I]
Hi Petr or maybe not?
Finalize python

My input is in italics.

In case it does not work maybe you could use something else that Python, like PBLua or Bint32.
Or wait for Python 3000

Bye,
Petr

Thanks Petr

Console under pbwin 8 using win32api didn't work either. It does work under c I've included the translated code below for those wanting to test.

//gcc -o cpy.exe cpy.c -lpython25
#include "c:\python25\include\python.h"
int main() {
 printf("Initiate python");
 Py_Initialize();
 PyRun_SimpleString("print '>>> hello from python <<<'");
 PyRun_SimpleString("import sys");
 PyRun_SimpleString("print '>>> modules: <<<'");
 PyRun_SimpleString("print sys.builtin_module_names");
 PyRun_SimpleString("print '>>> module keys: <<<'");
 PyRun_SimpleString("print sys.modules.keys()");
 PyRun_SimpleString("execfile('foo.py')");
 printf("Finalize python");
 Py_Finalize();
 return 0;
}
