Subject: [CastXML] Parsing class with nested struct definition.
Message-ID: <56F6448D.7010904@gmail.com>

I'm trying to use pygccxml to auto-generate some C++. The problem I'm 
having is if I have a class like:

class MyClass {
     struct SomeStruct {
        int structmem;
     };

     SomeStruct classmem;
};

When I look at the variables of the MyClass declaration, its listing 
both structmem and classmem as members. Is there a way to tell that 
structmem is a member of SomeStruct and that SomeStruct was defined 
inside of MyClass?

Hi

as you discovered, the variables() method will return all the variables found
under a specific node in the declarations tree.

I wrote a small example showing how to access the parent declaration of a variable.
The loops at the end show how you could filter out the variables from the different
classes/structs. The last one shows how to use the recursive=False option to get
variables from the first level only.

I hope this helps.

Just a small comment on my code, the "if isinstance(var, declarations.variable_t)? checks
are not needed. I was on an experimental branch, were some stuff was broken.
The variables() method only returns variables; this check is superfluous.

Subject: [CastXML] [ANNOUNCE] pygccxml v1.7.3 released
References: <91E8DBA9-84C4-4231-B305-14209288BFB4@gmail.com>

Hi

I am really pleased to announce that pygccxml v1.7.3 has been released.

pygccxml is a specialized XML reader that reads the output from CastXML or GCC-XML.
It provides a simple framework to navigate C++ declarations, using Python classes.
https://github.com/gccxml/pygccxml <https://github.com/gccxml/pygccxml>

This version brings many bug fixes, especially for people working with py++.

The release notes can be found here:
http://pygccxml.readthedocs.org/en/develop/history.html#version-1-7- <http://pygccxml.readthedocs.org/en/develop/history.html#version-1-7->3

A special thanks to all the contributors which made this release possible !

Michka
