Log4mql is an MQL4 (MetaQuotes MetaTrader 4 Language) library for flexible logging to files and terminal console. It is modeled after the Log4j Java library.

Documentation (GitHub): https://github.com/swaypnet/Log4mql

Usage in your code:

 CLog4mql::getInstance().error( __file__ , __line__ , "Something unexpected happened" );

or (for more frequent use)

 CLog4mql* logger = CLog4mql::getInstance();
Logger.Error( __file__ , __line__ , "Something unexpected happened" );
Logger.info( __file__ , __line__ , "Complete calculation" );
logger.debug( __file__ , __line__ , string format ( "The result of %s is %d" , string1, value1));

Don't forget at the end of your EA/indicator/script:

 CLog4mql::release();

or

 Logger.release();
