pybind/pybind11 - 2023-06-06

Seamless operability between C++11 and Python
12.9k star

pybind11 可实现 C++11 和 Python 之间的无缝操作。

pybind11 是一个轻量级的只包含一组头文件的 C++ 库，可以在 Python 中使用 C++ 类型。主要用于创建已有 C++ 代码的 Python 封装版本。其目的和语法类似于 Boost.Python 库。为什么要创建这个项目的原因就是因为 Boost 。作者认为 Boost 很大很复杂。而目前的 C++11 兼容的编译器使用已经非常广泛，所以希望开发一个更轻量级更具备兼容性的项目。

除去注释之外，该项目的核心头文件只有 2500 行左右代码，依赖于 Python (2.7 或者 3.x) 和标准 C++ 库。这么精简的实现有赖于新的 C++11 语言特性。特别是元组、Lambda 函数以及可变模板。自从项目创建以来，其增长已经超过了 Boost.Python。

ChunelFeng/CGrap - 2022-08-01

312 star

本工程实现了一套无任何第三方依赖的跨平台图流程计算框架。通过GPipeline(流水线)底层调度，实现了依赖元素依次顺序执行、非依赖元素并发执行的调度功能。

使用者只需继承GNode(节点)类，实现子类的run()方法，并根据需要设定依赖关系，即可实现任务的图化执行。

同时，使用者还可以通过设定各种包含多节点信息的GGroup(组)，自行控制图的条件判断、循环和并发执行逻辑。

此外，还可以通过添加GAspect(切面)的方式，实现以上各种元素功能的横向扩展，或是通过引入各种GAdapter(适配器)对单个节点功能进行加强。

scanf for modern C++

#include

int main() {
    int i;
    // Read an integer from stdin
    // with an accompanying message
    scn::prompt("What's your favorite number? ", "{}", i);
    printf("Oh, cool, %d!", i);
}

// Example result:
// What's your favorite number? 42
// Oh, cool, 42!

scnlib is a modern C++ library for replacing scanf and std::istream. This library attempts to move us ever so closer to replacing iostreams and C stdio altogether. It’s faster than iostream (see Benchmarks) and type-safe, unlike scanf. Think {fmt} but in the other direction.

sebastiandev/zipper - 2022-07-12

C++ wrapper around minizip compression library
393 star

Zipper’s goal is to bring the power and simplicity of minizip to a more object oriented/c++ user friendly library. It was born out of the necessity of a compression library that would be reliable, simple and flexible. By flexibility I mean supporting all kinds of inputs and outputs, but specifically been able to compress into memory instead of been restricted to file compression only, and using data from memory instead of just files as well.

#include

// You can use "dbg(..)" in expressions:

  if (dbg(n <= 1)) {
    return dbg(1);

    return dbg(n * factorial(n - 1));
  }
}

int main() {
  std::string message = "hello";
  dbg(message);  // [example.cpp:15 (main)] message = "hello" (std::string)

  const int a = 2;
  const int b = dbg(3 * a) + 1;  // [example.cpp:18 (main)] 3 * a = 6 (int)

  std::vector<int> numbers{b, 13, 42};
  dbg(numbers);  // [example.cpp:21 (main)] numbers = {7, 13, 42} (std::vector)

  dbg("this line is executed");  // [example.cpp:23 (main)] this line is executed

  factorial(4);

  return 0;
}

A macro for printf-style debugging fans.

Debuggers are great. But sometimes you just don’t have the time or patience to set up everything correctly and just want a quick way to inspect some values at runtime.

This projects provides a single header file with a dbg(…) macro that can be used in all circumstances where you would typically write printf(“…”, …) or std::cout << …. But it comes with a few extras.

C++ Design Patterns
2.4k star

Software design patterns are general reusable solutions to problems which occur over and over again in object-oriented design enviroment. It is not a finished design that can be transformed into source code directly, but it is template how to solve the problem. We can classify them by purpose into creational (abstract the instantiation process), structure (how classes and objects are composed to form larger structures) and behavioral patterns (the assignment of responsibilities between objects).
