[pygccxml-development] Problems with long filename

[Birgir S. <Bir...@ro...>]

Hei , I am using Py++ to expose the following.

class AbstractLoader : private boost::noncopyable {
public:
 =0D
  AbstractLoader();
  virtual ~AbstractLoader();

  std::vector < std::string > extensions() const;
 =0D
private:
  virtual std::vector < std::string > extensions_impl() const =3D 0;
};

I want to use the module_builder_t.split_module
but I am getting the following error message.

IOError: [Errno 36] File name too long:=
 u'splitted/vector_less_std_scope_basic_string_less_char_comma__std_scope_c=
har_traits_less_char_grate__comma__std_scope_allocator_less_char_grate___gr=
ate__comma_std_scope_allocator_less_std_scope_basic_string_less_char_comma_=
_std_scope_char_traits_less_char_grate__comma__std_scope_allocator_less_cha=
r_grate___grate___grate___grate_.pypp.hpp'

How can I tell Py++ not to autogenerate so long names?

Best regards,
Birgir Sigurjonsson.

Take a look on this "how to":
http://language-binding.net/pyplusplus/documentation/how_to.html#py-generated-file-name-is-too-long
After it you I think you would like to read this:
http://language-binding.net/pyplusplus/documentation/hints.html

Does it help?

Hei, I cannot get any of those to work, as it seems to me
that they are based on the fact that I have declared the
classes.

I added this
holder =3D mb.class_( 'std::vector < std::string >')
holder.rename( 'StringVector' )

and got this error

pygccxml.declarations.matcher.declaration_not_found_t: Unable to find=
 declaration.  matcher: [(decl type=3D=3Dclass_t) and (name=3D=
=3Dstd::vector < std::string >)

In my case it is the return type (stl container) that
is beeing auto converted to a class_ by Py++

Is there any other way?

Birgir

this is because the name of the class is different. First of all
you've got the class name
first time when you get IOError

Second you can find the exact name of the class in few ways:

1. for x in mb.classes( lambda cls: cls.name.startswith( 'vector<' ) ):
        print x.name

2. al_cls = mb.class_( 'AbstractLoader' )
    extensions = al_cls.mem_fun( 'extensions' )
    rtype = extensions.return_type
    print rtype
    rtype_cls = declarations.class_traits.get_declaration( rtype )
    rtype.alias = 'vector_of_strings'

Not really, but the solution I described should work

Hei, I have tried both method, but no success yet.

1. when printing out mb.classes() there is not class
that starts with vector.

2. in the following example I get an error declarations.
How do I define the declarations?
=0D
 al_cls =3D mb.class_( 'AbstractLoader' )
 extensions =3D al_cls.mem_fun( 'extensions' )
 rtype =3D extensions.return_type
 print rtype
 rtype_cls =3D declarations.class_traits.get_declaration( rtype )
 rtype.alias =3D 'vector_of_strings'


Thanks for you help,

Birgir.

May I see your code that reproduce the bug? Something fundamentally
wrong or broken.
At best the example would consist from single header file and Py++ script.

Hei, here is my header file.

#include <boost/utility.hpp>
#include <boost/shared_ptr.hpp>
#include <string>
#include <vector>

class AbstractLoader : private boost::noncopyable {
public:
 =0D
  AbstractLoader();
  virtual ~AbstractLoader();

  std::vector < std::string > extensions() const;
 =0D
private:
  virtual std::vector < std::string > extensions_impl() const =3D 0;
};


But mb.class_() does not find the class gives the following error.

pygccxml.declarations.matcher.declaration_not_found_t: Unable to find=
 declaration.  matcher: [(decl type=3D=3Dclass_t) and (name=3D=
=3Dstd::vector<std::basic_string<char, std::char_traits<char>,=
 std::allocator<char> >,std::allocator<std::basic_string<char,=
 std::char_traits<char>, std::allocator<char> > > >)]

This is printed out as the return type from the extensions function.
std::vector<std::basic_string<char, std::char_traits<char>,=
 std::allocator<char> >,std::allocator<std::basic_string<char,=
 std::char_traits<char>, std::allocator<char> > > >

                                      )

#rtype.alias =3D 'vector_of_strings'

for m in mb.classes():

In order to use type_traits  functionality it is necessary to import
declarations package from pygccxml

from pygccxml import declarations

Now this will fail for another reason: std::vector< std::string > is class
declaration,
as opposite to class definition. So if you will wrote next 2 lines as:

rtype_cls = declarations.class_declaration_traits.get_declaration( rtype )
rtype.alias = 'vector_of_strings'

This will work.

I also forgot to ask you what version of Py++ pygccxml you use.
Because in order to enjoy from semi automatic aliasing you need
latest version of py++ and pygccxml.

Automatic aliasing:
add next code somewhere in a file, which is passed to gccxml, in global
namespace:

namespace pyplusplus{ namespace aliases{
    typedef std::vector < std::string > vvvvvvvv;
}}

Py++ will automaticly pick the name
