Standard logging facilities (interface).
To use one of the standard log channels, put something like the following at the start of your .cpp file:
static lg::log_domain log_display("display"); #define ERR_DP LOG_STREAM(err, log_display) #define LOG_DP LOG_STREAM(info, log_display)
Then stream logging info to ERR_DP, or LOG_DP, as if it were an ostream like std::cerr. (In general it will actually be std::cerr at runtime when logging is enabled.)
LOG_DP << "Found a window resize event: ...";
Please do not use iomanip features like std::hex directly on the logger. Because of the design of the logger, this will result in all of the loggers (in fact std::cerr) being imbued with std::hex. Please use a formatter instead.
#include "formatter.hpp"
LOG_DP << (formatter() << "The random seed is: '" << std::hex << seed << "'\n").str();
It might be nice if somehow the logger class / macros could support using iomanip things directly, but right now it doesn't, and it seems that it would complicate the design greatly enough that it doesn't seem worth it.
