[C++-sig] [Py++] operators() got an unexpected keyword argument 'decl_type'
Hello,
I need to exclude some operators from my wrapped python classes, but I seem not
to be able to access the operators.
What is wrong with this code:
--8<--
from pyplusplus import module_builder
files=["test.H"]
mb = module_builder.module_builder_t(
files=files,
)
print mb.operators()
--8<--
(For completeness, test.H contains nothing but "class X{public: int i(); };"
The following error, however, occurs independent of test.H.)
On the last line the script produces:
--8<--
Traceback (most recent call last)
/home/wj/tmp/ in ()
/usr/lib/python2.5/site-packages/pyplusplus/module_builder/builder.py in
operators(self, name, symbol, return_type, arg_types, decl_type, header_dir,
header_file, recursive)
541 , header_dir=header_dir
542 , header_file=header_file
--> 543 , recursive=recursive )
544
545 def member_function( self, name=None, function=None,
return_type=None, arg_types=None, header_dir=None, header_file=None,
recursive=None ):
: operators() got an unexpected keyword argument
'decl_type'
--8<--
The installation is latest gccxml from CVS, pygccxml-1.0.0 and pyplusplus-1.0.0
with python 2.5.2. Same result with python 2.6.
Please help. Is the use of mb.operators() wrong, or what else might be the
problem?

How can one allow Py++ to handle member functions that return a reference to an
immutable type?
For example this X::getval function:
class X{
double xval;
public:
double& getval(){return xval;}
};
I don't care about the reference. All I need is the double value, which is only
used as an r-value. Can one use a call policy in this situation, or does one
have to write custom wrapper code?
Regards,
Bennie

The version you use contains such bug. It is fixed in SVN.
If you don't want to upgrade you can use the following code:
mb.global_ns.operators() # query global namespace for all operators

Did you read Boost.Python manuals?
http://www.boost.org/doc/libs/1_39_0/libs/python/doc/v2/copy_non_const_reference.html
from pyplusplus.module_builder import call_policies
...
mb.calldef( '::X::getval' ).call_policies =
call_policies.return_value_policy(
call_policies.copy_non_const_reference )
