std.experimental.logger.core.Logger.logf - multiple declarations

Function Logger.logf

This function logs data to the used Logger with a specific LogLevel and depending on a condition in a printf-style manner.

void logf(int line = __LINE__, string file = __FILE__, string funcName = __FUNCTION__, string prettyFuncName = __PRETTY_FUNCTION__, string moduleName = __MODULE__, A...) (
  const LogLevel ll,
  lazy bool condition,
  lazy string msg,
  lazy A args
);

In order for the resulting log message to be logged the LogLevel must be greater or equal than the LogLevel of the used Logger and must be greater or equal than the global LogLevel and the condition must be true.

Parameters

NameDescription
ll The specific LogLevel used for logging the log message.
condition The condition must be true for the data to be logged.
msg The format string used for this log call.
args The data that should be logged.

Example

auto s = new FileLogger(stdout);
s.logf(LogLevel.trace, true ,"%d %s", 1337, "is number");
s.logf(LogLevel.info, true ,"%d %s", 1337, "is number");
s.logf(LogLevel.warning, true ,"%d %s", 1337, "is number");
s.logf(LogLevel.error, false ,"%d %s", 1337, "is number");
s.logf(LogLevel.fatal, true ,"%d %s", 1337, "is number");
