Intra-application dependencies between modules

[krivenko]

When cpp2py was a part of triqs, it was possible to define a wrapped type in one Python module, and then use it in another module of the same application. For example, I could have the following description file,

module = module_(full_name = "module4", doc = "My application", app_name = "myapp")

module.use_module('module1', 'myapp')
module.use_module('module2', 'myapp')
module.use_module('module3', 'myapp')

Can I achieve a similar effect with the new cpp2py?
As far as I can see, use_module() is now not a thing...

just import the module in the desc.
All information is now contained in the module, including the type converters, various tables.

Thank you for the answer!
For the sake of testing, I am now trying to add a second module to cthyb.

from cpp2py.wrap_generator import *

# The module
module = module_(full_name = "test_module", doc = "The cthyb solver", app_name = "solver_core")

# Imports
import pytriqs.gf
import pytriqs.operators
import pytriqs.statistics.histograms
import pytriqs.atom_diag
import solver_core

module.generate_code()

There seems to be a problem with some mako template:

which module do you want to add to cthyb ?

[krivenko]

I don't want to modify cthyb.

I just use it as a working setup to learn how inter-module dependencies work.
The module I'm trying to add is called test_module, and its .desc file is posted in the previous comment. Here are the lines I added to CMakeLists.txt:

add_cpp2py_module(test_module)

target_link_libraries(test_module cthyb_c)

target_include_directories(test_module PRIVATE ${CMAKE_CURRENT_SOURCE_DIR})

The simplest would be for me to see your dev branch.
