Show HN: C++, Java and C# light-weight-logger

This is a library I've been working on with versions for C++, java & C# where you make custom formats and Log based on them, for example you could make an ERROR Like this:

  [ERROR] [date, time-stamp, time-zone] <main log message> (file:thread-ID:line)

but you would write it like this:

  // define the master format

  master_style = "%C[%N]%c%S%G[%D %T %Z]%c %M %G(%F:%t:%L)";

  // tell the logger what colour to use for a given name

  logger.add_format("ERROR", master_style, Colour::RED);

so now the [ERROR] part will be red, the time area will be grey, and the location grey, but you could really make any style you wanted. And once you have a master format you could also add different types of logs:

  logger.add_format("SUCCESS", style_minimal, Colour::GREEN);
  logger.add_format("INFO", master_style, Colour::CYAN);
  logger.add_format("WARN", master_style, Colour::YELLOW);

also the %S we put in there is actualy a colum padder so you logs will be inline:
