FunctionalPlus C++ 编码库 项目简介
FunctionalPlus 是一个小的表头库，它可以降低代码噪声，一次只处理一个单一等级的的抽象对象。通过增加你的代码的简洁性和可维护性来提高生产效率和编码乐趣。从长远的角度来看，它可以通过提供易于使用的功能将你从实现控制的流中解放出来。示例代码：#include "FunctionalPlus/FunctionalPlus.h"#include <iostream>
// std::list<std::uint64_t> CollatzSeq(std::uint64_t x) { ... }int main()
{ using namespace FunctionalPlus;
using namespace std;
typedef list<uint64_t> Ints;
// [1, 2, 3 ... 29]
auto numbers = GenerateIntegralRange<Ints>(1, 30);
// A function that does [1, 2, 3, 4, 5] -> "[1 => 2 => 3 => 4 => 5]"
auto ShowInts = Bind1of2(ShowContWith<Ints>, " => ");
// A composed function that calculates a Collatz sequence and shows it.
auto ShowCollatsSeq = Compose(CollatzSeq, ShowInts);
// Apply it to all our numbers.
auto seqStrs = Transform(ShowCollatsSeq, numbers);
// Combine the numbers and their sequence representations into a map.
auto collatzDict = CreateMap(numbers, seqStrs);
// Print some of the sequences.
cout << collatzDict[13] << endl;
cout << collatzDict[17] << endl;
}
// std::list<std::uint64_t> CollatzSeq(std::uint64_t x) { ... }int main()
{ using namespace FunctionalPlus;
using namespace std;
typedef list<uint64_t> Ints;
// [1, 2, 3 ... 29]
auto numbers = GenerateIntegralRange<Ints>(1, 30);
// A function that does [1, 2, 3, 4, 5] -> "[1 => 2 => 3 => 4 => 5]"
auto ShowInts = Bind1of2(ShowContWith<Ints>, " => ");
// A composed function that calculates a Collatz sequence and shows it.
auto ShowCollatsSeq = Compose(CollatzSeq, ShowInts);
// Apply it to all our numbers.
auto seqStrs = Transform(ShowCollatsSeq, numbers);
// Combine the numbers and their sequence representations into a map.
auto collatzDict = CreateMap(numbers, seqStrs);

cout << collatzDict[13] << endl;
cout << collatzDict[17] << endl;
