#define SM_	(		I,

Value:

        arg_router::multi_lang::string_selector<I,                                       \
                                                BOOST_PP_ENUM(                           \
                                                    BOOST_PP_VARIADIC_SIZE(__VA_ARGS__), \
                                                    AR_SM_UNPACK,                        \
                                                    BOOST_PP_VARIADIC_TO_ARRAY(__VA_ARGS__))>

A multi-language equivalent to S_, only for use within a multi_lang::root call.

Specify the string language variants in the order they are declared in the owning multi_lang::root.

arp::long_name<SM_("help", "aider", "ayuda")>

Note

This has now been superceded by multi_lang::root_t, and will be removed in v2

The macro creates compile_time_string types from the inputs and puts them into a string_selector. There is no requirement to use this macro, it's just a convenience.

Parameters

I	Index to select
