Detailed Description

Full-automation entry point for the LuaCATS stub rod: the WELDER_LUACATS_MAIN generator-main() macro.

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

Definition in file module.hpp.

Value:

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

Define a main() that emits the LuaCATS stub 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: a generator executable links this and welder_luacats_generate_stub runs it with the output path to produce <ns>.lua.

Parameters

ns	the top-level namespace / module name token.
