Programming exercise to implement a logger class

Build it with:

cmake .
make
./cpplogger

And/or run unit-tests, using catch2 as a submodule.

git submodule update --init --recursive
cmake . -DBUILD_TESTS=ON
make
./cpplogger_test

The binary can be used as a command line tool:

./cpplogger
Usage: cpplogger [OPTION]
Logs the input (till EOF) to the console or to a file.

Options:
        -c,             log to console
        -f FILE         log to FILE
        -t,             prefix lines with timestamp
        -n,             prefix lines with hostname
        -u,             prefix lines with user name
        -h              print this help

Option -c and -f are mutually exclusive, specify one.

Examples:

./cpplogger -t -u -c
hello world

how is it going

cat /tmp/this.txt | ./cpplogger -f /tmp/that.txt

Or used as a library

#include <Logger.hpp>

Logger::getInstance()->setStream(std::ostream* os);

Logger::getInstance()->setPrintTimeStamp(true);
Logger::getInstance()->setPrintUserName(false);

LOG  << word1 << word2 << variable << END;
