* 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);
});
