Looking for a simple logger for your C++ project? SimpleLogger might be for you.
- Based on RAII
- Configurable level symbols
- Datetime / EPOCH timestamps
- Logging levels:
Trace,Debug,Info,Warning,Error,Fatal - Log to file and/or console
- Thread-safe
- Uses streams (<< operator)
- Very easy to use
Just add src/simple_logger.hpp and src/simple_logger.cpp to your project and start using it!
Copy contents of SimpleLogger under your main project (or clone as a Git submodule).
In your CMakeLists.txt:
add_subdirectory(SimpleLogger EXCLUDE_FROM_ALL)
include_directories(SimpleLogger/src)
Link to the library:
target_link_libraries(${YOUR_TARGET_NAME} SimpleLogger_static)
In your code:
#include "simple_logger.hpp"
Build and install:
$ mkdir build && cd build
$ cmake ..
$ make
$ sudo make install
Link to libSimpleLogger_static.a or libSimpleLogger.so.
Note: instead of Logger class you can simply use L.
using juzzlin::L;
L().info() << "Something happened";
Outputs something like this:
Sat Oct 13 22:38:42 2018 I: Something happened
using juzzlin::L;
L::init("/tmp/myLog.txt");
L().info() << "Something happened";
using juzzlin::L;
L::init("/tmp/myLog.txt");
L::enableEchoMode(false);
L().info() << "Something happened";
using juzzlin::L;
L::setLoggingLevel(L::Level::Debug);
L().info() << "Something happened";
L().debug() << "A debug thing happened";
Outputs something like this:
Sat Oct 13 22:38:42 2018 I: Something happened
Sat Oct 13 22:38:42 2018 D: A debug thing happened
using juzzlin::L;
L::setLoggingLevel(L::Level::Debug);
L::setLevelSymbol(L::Level::Debug, "<DEBUG>");
L().debug() << "A debug thing happened";
Outputs something like this:
Sat Oct 13 22:38:42 2018 <DEBUG> A debug thing happened
Possible modes: None, EpochSeconds, EpochMilliseconds, EpochMicroseconds, DateTime.
using juzzlin::L;
L::setTimestampMode(L::TimestampMode::EpochMilliseconds, " ## ");
L().info() << "Something happened";
Outputs something like this:
1562955750677 ## I: Something happened
using juzzlin::L;
std::stringstream ssI;
L::setStream(L::Level::Info, ssI);
