Logging facility
Within the log message text, escape sequences are supported for dynamically formatting the message.
Escape sequences have either the form n or %<format specifier>n, where the index n starts at 1.
The index specifies the position of the argument in the list. They can appear in any given order. An index can be used more than once, and not all indexes have to be present (in which case the argument will not be printed). The input value is automatically converted to string format and can be among std::string, char *, int, uint64_t and more.
The format specifier is the same as used in printf and sprintf.
int channels = 2;
int sample_rate = 44100:
Logging::debug(filename,
"Audio %1 channels %2 Hz", channels, sample_rate);
static void debug(const T filename, const std::string &format_string, Args &&...args)
Write debug level log entry.
Prints "Audio 2 channels 44100 Hz".
int channels = 2;
double sample_rate = 44.1:
Logging::debug(filename,
"Audio %1 %<.3f>2 KHz", channels == 2 ?
"stereo" :
"mono", sample_rate);
Prints "Audio stereo 44.100 KHz".
