If you have many commands in your bot, and want to handle commands from multiple sources, you should consider instantiating a dpp::commandhandler object. This object can be used to automatically route commands and their parameters to functions in your program. A simple example of using this object to route commands is shown below, and will route both the /ping (global slash command) and .ping (prefixed channel message command) to a lambda where a reply can be generated.
Note that because the dpp::commandhandler::add_command method accepts a std::function
as the command handler, you may point a command handler at a simple lambda (as shown in this example), a function pointer, or an instantiated class method of an object. This is extremely flexible and allows you to decide how and where commands should be routed, either to an object oriented system or to a lambda based system.
