About

Library cpputils is a collection of utility classes designed to simplify common tasks in C++ development. The library includes classes for logging, stream manipulation and timing.

Features

• Logger: A simple logging class to output messages to the console.
• StreamEater: A class to capture and manipulate stream output.
• Timer: A class to measure execution time in various time units.

Building

Clone and use CMake directly or via any IDE supporting it. CMake should:

• configure everything automatically,
• compile and create binaries.

As a result of compilation, library binary and binary with examples should be created. Library can be used as a shared or static one. For shared library use on Windows, define CPPUTILS_SHARED_LIB. Check include/cpputils/dll.h for more details.

Used tools

Tool	Windows	Ubuntu
OS version	10 22H2	24.04
GCC	13.1.0	13.2.0
CMake	3.30.2	3.28.3
Git	2.46.0	2.43.0

Usage

One of the ways is to include in project file CMakeLists.txt.cpputils containing:

include(FetchContent)

FetchContent_Declare(
    cpputils
    GIT_REPOSITORY https://github.com/przemek83/cpputils.git
    GIT_TAG <tag/branch>
)

FetchContent_MakeAvailable(cpputils)

and adding in CMakeLists.txt:

include(CMakeLists.txt.cpputils)

From this point onwards, it should be possible to use cpputils as a link library:

target_link_libraries(${PROJECT_NAME} cpputils)

Check the examples subproject and my other project named data-explorer for usage examples.

Logger

#include <cpputils/Logger.h>
...
Logger logger;
logger.info("This is a log message.");
logger.error("This is error message.");

Log().info("This is short form.");

Result:

This is a log message.
This is error message.
This is short form.

StreamEater

#include <cpputils/StreamEater.h>
...
std::string eaten;
{
    const StreamEater eater(std::cout);
    std::cout << "This will be captured." << std::endl;
    eaten = eater.getOutput();
}
std::cout << "Captured output: " << eaten << std::endl;

Result:

Captured output: This will be captured.

Timer

#include <cpputils/Timer.h>
...
{
    Timer timer{Timer::Duration::MILISECONDS};
    std::this_thread::sleep_for(std::chrono::seconds(1));
}

Result:

Execution time: 1000ms
