PTCLogs library
PTCLogs is a library for pretty and configurable logs.
Installation

git clone http://github.com/ptcar2009/ptclogs
cd ptclogs
make install
Usage
To compile the library, you need to link the library in compilation.
gcc -o main main.cpp -lptclogs
Log level configuration
Log level can either be set via a parameter on instantiation or by a environment variable.
If set by an environment variable, you need to set the VERBOSITY environment variable to a number between 0 and 5, being 0 the lowes verbosity with only fatal logs and 5 the highest, containing debug logs.
If set by instantiation, it's a parameter in the Logger class.
Console Logger
Console logger is for easily readable console logs with configurable log level sensitivity.
Example
#include <ptclogs/driver/console_driver.hpp>
#include <ptclogs/logs.hpp>
#include <string>
using namespace logger;
using logger::Field;
using std::string;
int main() {
auto logger = Logger<ConsoleDriver>();
logger.INFO("this is a message in info level", Field<int>("number", 12),
Field<string>("string", "hello I am string"));
logger.DEBUG("this is a message in debug level", Field<int>("error", 12));
logger.ERROR("this is a message in error level");
}
JSON logger
JSON logger encodes all information in machine readable JSON formatted objects.
Example
#include <ptclogs/driver/json_driver.hpp>
#include <ptclogs/logs.hpp>
#include <string>
using namespace logger;
using logger::Field;
using std::string;
int main() {
auto logger = Logger<JSONDriver>();
logger.INFO("this is a message in info level", Field<int>("number", 12),
Field<string>("string", "hello I am string"));
logger.DEBUG("this is a message in debug level", Field<int>("error", 12));
logger.ERROR("this is a message in error level");
}
