Macros
#define	WELDER_OPAQUE_CONTAINERS_MAIN_STYLED(ns, style)
	Like WELDER_OPAQUE_CONTAINERS_MAIN, but with a custom name style — a welder::naming style that may carry a transform_opaque_container hook to name the opaque wrappers (see document.hpp / the Containers guide).
#define	WELDER_OPAQUE_CONTAINERS_MAIN(ns)
	Define a main() that emits the opaque-container header for namespace ns.

Detailed Description

Full-automation entry point for the opaque-container generator rod: the WELDER_OPAQUE_CONTAINERS_MAIN generator-main() macro.

Include this (instead of rod.hpp) in a generator TU so the whole executable is one macro line; welder_generate_opaque_containers() (CMake) builds and runs it into <name>.opaque.hpp.

Definition in file module.hpp.

WELDER_OPAQUE_CONTAINERS_MAIN

#define WELDER_OPAQUE_CONTAINERS_MAIN

(

ns

)

Value:

WELDER_OPAQUE_CONTAINERS_MAIN_STYLED(ns, ::welder::naming::none)

Define a main() that emits the opaque-container header for namespace ns.

Writes to the file named by the first command-line argument, or to stdout when none is given — the build-time analogue of a backend entry point: welder_generate_opaque_containers runs the generator with the output path. Uses the default (collision-free derived) names; for custom naming use WELDER_OPAQUE_CONTAINERS_MAIN_STYLED.

Parameters

ns	the top-level namespace / module name token.

WELDER_OPAQUE_CONTAINERS_MAIN_STYLED

#define WELDER_OPAQUE_CONTAINERS_MAIN_STYLED	(		ns,
			style )

Value:

int main(int argc, char** argv) {                                                   \
    if (argc > 1) {                                                                 \
        ::std::ofstream welder_out_{argv[1]};                                       \
        ::welder::rods::opaque_containers::rod::generate<^^ns, style>(welder_out_); \
    } else {                                                                        \
        ::welder::rods::opaque_containers::rod::generate<^^ns, style>(::std::cout); \
    }                                                                               \
    return 0;                                                                       \
}

Like WELDER_OPAQUE_CONTAINERS_MAIN, but with a custom name style — a welder::naming style that may carry a transform_opaque_container hook to name the opaque wrappers (see document.hpp / the Containers guide).

The default macro passes welder::naming::none (the collision-free derived names).

Parameters

ns	the top-level namespace / module name token.
style	a name-style type (its transform_opaque_container, if any, names the wrappers).
