awesome-hpp

Pros of fmt

• Actively maintained and widely used library for string formatting
• Provides a safe, fast, and extensible alternative to printf and iostreams
• Supports a wide range of formatting options and custom types

Cons of fmt

• Requires including an external library, increasing project dependencies
• May have a slight performance overhead compared to raw string manipulation
• Learning curve for developers unfamiliar with the fmt syntax

Code Comparison

fmt:

#include <fmt/core.h>

std::string name = "Alice";
int age = 30;
fmt::print("Hello, {}! You are {} years old.", name, age);

awesome-hpp (using std::format):

#include <format>
#include <iostream>

std::string name = "Alice";
int age = 30;
std::cout << std::format("Hello, {}! You are {} years old.", name, age);

Summary

fmt is a comprehensive formatting library, while awesome-hpp is a curated list of header-only C++ libraries. fmt offers more features and active development, but awesome-hpp provides a collection of lightweight alternatives. The choice depends on project requirements and preferences for external dependencies versus header-only solutions.

Pros of json

• Comprehensive JSON manipulation library with extensive features
• Well-documented and widely adopted in the C++ community
• Actively maintained with regular updates and improvements

Cons of json

• Focused solely on JSON, while awesome-hpp covers multiple header-only libraries
• Larger codebase and potential overhead for simple use cases
• May require more setup and integration compared to lightweight alternatives

Code Comparison

json:

#include <nlohmann/json.hpp>
using json = nlohmann::json;

json j = {
  {"name", "John"},
  {"age", 30},
  {"city", "New York"}
};
std::cout << j.dump(2) << std::endl;

awesome-hpp (using nlohmann/json as an example):

#include <nlohmann/json.hpp>
using json = nlohmann::json;

// Same code as above

Note: awesome-hpp is a curated list of header-only libraries, including json, so the code usage would be identical for this specific example. The main difference is that awesome-hpp provides a collection of various header-only libraries, while json focuses exclusively on JSON manipulation.

Pros of spdlog

• Focused, feature-rich logging library with high performance
• Supports various log targets (console, file, syslog, etc.)
• Actively maintained with frequent updates and improvements

Cons of spdlog

• Limited to logging functionality only
• Steeper learning curve for advanced features
• Larger codebase compared to single-header libraries

Code Comparison

spdlog:

#include "spdlog/spdlog.h"

int main() {
    spdlog::info("Welcome to spdlog!");
    spdlog::error("Some error message with arg: {}", 1);
}

awesome-hpp:

#include "fmt/format.h"

int main() {
    fmt::print("Welcome to fmt!\n");
    fmt::print(stderr, "Some error message with arg: {}\n", 1);
}

Summary

spdlog is a comprehensive logging library with advanced features and high performance, while awesome-hpp is a curated list of single-header C++ libraries, including fmt for formatting. spdlog offers more logging-specific functionality but has a larger footprint, whereas awesome-hpp provides a collection of lightweight, header-only libraries for various purposes. The choice between them depends on whether you need a dedicated logging solution or prefer a more modular approach with single-header libraries.

Pros of Catch2

• Comprehensive testing framework with built-in assertion macros and test organization
• Extensive documentation and community support
• Single header file implementation for easy integration

Cons of Catch2

• Larger codebase and potentially slower compilation times
• Steeper learning curve for advanced features
• May be overkill for simple projects or small libraries

Code Comparison

Catch2:

#define CATCH_CONFIG_MAIN
#include <catch2/catch.hpp>

TEST_CASE("Example test") {
    REQUIRE(1 + 1 == 2);
}

awesome-hpp:

#include <cassert>

int main() {
    assert(1 + 1 == 2);
    return 0;
}

Summary

Catch2 is a full-featured testing framework, while awesome-hpp is a curated list of header-only C++ libraries. Catch2 provides a robust testing environment with built-in assertions and test organization, making it suitable for large-scale projects. However, it may be excessive for smaller projects or libraries.

awesome-hpp offers a collection of lightweight, header-only libraries that can be easily integrated into projects. While it doesn't provide a testing framework itself, it includes various utility libraries that can be useful for different aspects of C++ development.

Choose Catch2 for comprehensive testing needs in larger projects, and consider libraries from awesome-hpp for specific functionality in a header-only format.

Pros of rapidjson

• Highly optimized for performance, making it one of the fastest JSON parsers available
• Supports both SAX and DOM parsing styles, offering flexibility for different use cases
• Provides extensive documentation and examples for easy integration

Cons of rapidjson

• Focused solely on JSON parsing, while awesome-hpp covers a broader range of C++ utilities
• Larger codebase and more complex API compared to some lightweight alternatives
• May be overkill for simple JSON parsing needs in smaller projects

Code Comparison

rapidjson:

Document d;
d.Parse(json);
Value& s = d["stars"];
s.SetInt(s.GetInt() + 1);

awesome-hpp (using nlohmann/json as an example):

auto j = json::parse(json_string);
j["stars"] = j["stars"].get<int>() + 1;

Summary

rapidjson is a specialized JSON library focused on high performance, while awesome-hpp is a curated list of header-only C++ libraries covering various functionalities. rapidjson offers more JSON-specific features and optimizations, but awesome-hpp provides a broader range of utilities for different C++ development needs. The choice between them depends on the specific requirements of your project and whether you need a dedicated JSON parser or a collection of versatile C++ tools.

Pros of magic_enum

• Focuses specifically on enum reflection and manipulation
• Provides a more comprehensive set of enum-related utilities
• Supports C++17 and later, offering modern C++ features

Cons of magic_enum

• Limited to enum-related functionality
• May have a steeper learning curve for beginners
• Requires C++17 or later, which might not be suitable for all projects

Code Comparison

magic_enum:

enum class Color { Red, Green, Blue };
auto color_name = magic_enum::enum_name(Color::Red);
auto color_value = magic_enum::enum_cast<Color>("Green");

awesome-hpp:

#include <iostream>
#include "fmt/format.h"

int main() {
    fmt::print("Hello, {}!", "world");
    return 0;
}

Summary

magic_enum is a specialized library for enum reflection and manipulation, offering a comprehensive set of tools for working with enums in modern C++. awesome-hpp, on the other hand, is a collection of various header-only C++ libraries covering a wide range of functionalities. While magic_enum excels in enum-related tasks, awesome-hpp provides a broader set of utilities for different purposes. The choice between the two depends on the specific needs of your project and the desired level of specialization.
