Fix compilation of py_converter. - py_converters in hpp files - add guard to prevent inclusion in the wrapper (to avoid 2 specialisation of the same py_converter). 2014-05-20 17:45:16 +02:00			`EXECUTE_PROCESS(COMMAND mkdir -p ${CMAKE_BINARY_DIR}/include/pytriqs/converters/)`

parameters & wrapper - new parameter class : parameters are viewed as form, built in C++, and filled in C++/python. Each field of the form as a precise C++ type (erased using standard techniques). First tests ok, to be reread/checked. TODO : serialization is commented. Lead to long compilation time & large code due to boost::serialization. Use h5 when possible. - wrapper : - separated the converters of the wrapped type in the TRIQS library - necessary for parameters (it used outside an .so) and potentially other codes, outside an .so module 2014-05-16 19:35:48 +02:00

wrapper: add use_module - a module can use the converters used by another with the use_module('A') command. In which case : - the generate converter header for A will be included. - the header, at the top, now contains a simple list of all wrapped types, which is then included in the wrapped_types of the module for proper code generation. - simplify the code generation : just generate_code. - all arguments are analyzed from sys.argv at the import of the wrap_generator module. In any case, the xx_desc.py will be called from the corresponding cmake command, hence with the right arguments. - Added a dependencies in my_module_B of wrap_test to show how to make the dependencies in the cmake file, if needed. 2014-05-30 19:21:38 +02:00			`${converter_name}`
