🎯 Goal

The goal of Faker C++ is to provide a library similar to Faker.js for C++ community. Faker C++ helps with the creation of realistic and customizable fake data for testing and development purposes within C++ applications.

Usage and Documentation

To properly use Faker C++ you must first consume the Faker library (see Consuming Library with CMake). Once that is done, you need to include the proper header files depending on the module you wish to generate data from. The module header file names can be found in docs.

Below is an example of how to use Faker C++ in your code.

#include <iostream>

#include "faker-cxx/Date.h"
#include "faker-cxx/Internet.h"
#include "faker-cxx/Location.h"
#include "faker-cxx/String.h"

int main()
{
    const auto id = faker::String::uuid();
    const auto email = faker::Internet::email();
    const auto password = faker::Internet::password();
    const auto city = faker::Location::city();
    const auto streetAddress = faker::Location::streetAddress();

    std::cout << id << std::endl;               // 58018063-ce5a-4fa7-adfd-327eb2e2d9a5
    std::cout << email << std::endl;            // [email protected]
    std::cout << password << std::endl;         // @cWLwgM#Knalxeb
    std::cout << city << std::endl;             // Sayre ville
    std::cout << streetAddress << std::endl;    // 1716 Harriet Alley

    return 0;
}

Consuming library with CMake (CMake 3.22 or newer)

1. Add faker to git submodules (execute in project root):

   mkdir externals && cd externals
   git submodule add https://github.com/cieslarmichal/faker-cxx.git
   git submodule update --init --recursive
   

2. Link with library:

   set(BUILD_TESTING OFF)
   
   add_subdirectory(externals/faker-cxx)
   
   add_executable(main Main.cpp)
   
   target_link_libraries(main faker-cxx)

Compiler support

• MSVC➚ version 143 or newer.
• GCC➚ version 12 or newer.
• Clang➚ version 16 or newer.
• Apple Clang➚ version 16 or newer.

Dependencies

• GTest (set BUILD_TESTING=OFF CMake flag to disable this dependency)
• fmt (only for compilers that don't support std::format)

In order to use external dependencies installed in your system, you can set the USE_SYSTEM_DEPENDENCIES CMake flag to ON.

Building the library with Conan

The library can be built using Conan package manager to solve external dependencies. To build the library with Conan, follow the steps below:

1. Install required dependencies:

   conan install conanfile.txt --build=missing

2. Build the library:

   cmake --preset=conan-release -DUSE_SYSTEM_DEPENDENCIES:BOOL=ON
   cmake --build --preset=conan-release
