Support for non-type template parameters

[sturdivant20]

In my c++ library I have multiple functions with non-type template arguments, e.g.

template <bool do_something = false>
void foo(int &x) {
  ...
  if constexpr (do_something) {
    ...
  }
}

The documentation has a clear method to generate python bindings for c++ functions with a template type. Is this type of templating supported and if so is there a clear method to implement a template argument?

I tried emulating the method for template types with no success

options.fn_template_options.add_specialization("foo", ["true"])
options.fn_template_options.add_specialization("foo", ["do_something=true"])

I end up with errors like

raise SrcmlcppException(f"Could not find a child of type {type_of_cpp_element}")
srcmlcpp.srcmlcpp_exception.SrcmlcppException: Could not find a child of type <class 'srcmlcpp.cpp_types.decls_types.cpp_decl_statement.CppDeclStatement'>

and

assert new_cpp_function is not None

I'm sorry, there is only support for type template arguments (and only one argument).

Adding support for them not type arguments is not planned at the moment.

Hi,
I'm currently working on binding cpp functions with multiple template parameters and not type arguments. Is it something planned to implement?
thanks

Hi,

This is not planned at the moment, I’m sorry.
You may add wrappers for each specialization you need and generate bindings for those instead.
PRs are welcome also.

Thanks
