Integration

Add source

To use Logger within your software project include the Logger source into your project

Source:

• logger.h/cpp - logger and base stuff
• logdefdest.h/cpp - default destinations for console and file
• log_base.h - macro for simple use logger
• logstream.h - log stream, it can be used to add output operator for your types
• funcinfo.h - macros for parsing signatures

or include logger.cmake in the cmake project (see example/CMakeLists.txt)

Add aliases

Recommended add own aliases to use logger stuff (type, level, color and etc) See example:

• logger.h
• logstream.h
• log.h
