By default D++ does not cache messages. The example program below demonstrates how to instantiate a custom cache using dpp::cache which will allow you to cache messages and query the cache for messages by ID.
This can be adjusted to cache any type derived from dpp::managed including types you define yourself.
- Note
- This example will cache and hold onto messages forever! In a real world situation this would be bad. If you do use this, you should use the dpp::cache::remove() method periodically to remove stale items. This is left out of this example as a learning exercise to the reader. For further reading please see the documentation of dpp::cache
#include <dpp/dpp.h>
#include <sstream>
int main() {
*m = event.msg;
std::string cmd;
ss >> cmd;
if (cmd == "!get") {
ss >> msg_id;
if (find_msg != nullptr) {
} else {
}
}
});
bot.start(false);
return 0;
}
