h

Switch on string constants!

Getting Started

Prerequisites

• CMake
• git

Installing

As a library:

Coming if anybody asks.

Adding it to your code:

Download h.h. Add it to you project. For example in a folder named include.

Include the header to your .cpp file containing you main function.

#include "include/h.h" // h::hash, h::operator ""_h
// ...

int main(int argc, char** argv) {
  switch (h::hash(argv[1], std::strlen(argv[1]))) {
    using namespace h::literals;
  case "foo"_h:
    // ...
  case "bar"_h:
    // ...
  }
}

Example

For a full example check out example.cpp.

#include <cstring>     // std::strlen
#include <cstdio>      // std::printf
#include "include/h.h" // h::hash, h::operator ""_h

int main(int argc, char** argv) {
  using namespace h::literals;
  
  if (argc < 2) return EXIT_FAILURE;
  
  switch (h::hash(argv[1], std::strlen(argv[1]))) {
  case "--version"_h:
    std::printf("com.viraltaco.h v%s\n", com_viraltaco_h_h);
    break;
  case "--help"_h:
  case "-h"_h:
    std::printf("--help\n");
    break;
  default:
    std::printf("Invalid input: '%s'\n", argv[1]);
    return EXIT_FAILURE;
  }
}
