Header only Logging Library

This is a header only lightweight logging library implemented using code from http://www.drdobbs.com/cpp/a-lightweight-logger-for-c/240147505 with some modifications.

Features

• Easy to use Macros
• Easy to enable/disable with definitions
• Include log file policy to write log to text file
• Interface class for custom log file policies
• Multiple log file policy support

Instructions

Please see the included main.cpp for examples of the following information.

Macros

• LOG_INIT this macro initializes the Logger object
• LOG_INST provides a symbol to the same Logger object (as long as you're in the same scope)
• LOG, LOG_ERR, LOG_WARN expands to a method call which will print the parametes in the parentesis that follow the macro e.g. LOG("log something...");
• LOGGING_LEVEL_1, LOGGING_LEVEL_2, LOGGING_LEVEL_3 These define the level or detail that is logged. They are:
  1. Only LOG_WARN messages are expanded
  2. LOG_WARN and LOG_ERR are expanded
  3. LOG_WARN, LOG_ERROR, and LOG are expanded
