* Simplifies the export declarations for module developers. While MAPI III utilized a flexible key-value vector to eliminate positional arguments in a header initializer, now the developer simply makes a list of pointers to what they want to export for injection into IRCd. Example: mapi::header IRCD_MODULE { "mymod", "My module adds a command, a hook, and a CLICAP", &my_cmdtab, &some_hook, &clicaptab }; * Distributes the handlers for items passed to the above vector. Anyone can add a type-handler to the module system from anywhere in IRCd (and other modules?) When your type is encountered a handler is called providing the symbol name to read out of the module. Example in parser.cc: mods::add_loader<Message>([] (mod &loading, const std::string &symbol) { auto &msg(get<Message>(loading, symbol)); add_command(msg.name, msg); });
