argreffunc is a c++ library for parsing command line arguments.

Quickstart

#include "arf/argreffunc.hpp"

int main(int argc, char* argv[]) {
    arf::Parser parser;

    std::string name = "you there"; // default value
    parser.add_argument("name", name)
          .add_alias("n");

    std::string domain;
    int port = 22;
    parser.add<std::string>("url", [&](std::string url) -> void {
        auto colon_loc = url.find(':');
        domain = url.substr(0, colon_loc);
        if (colon_loc != std::string::npos) {
            auto substring = url.substr(colon_loc + 1, url.size() - colon_loc - 1);
            port = std::stoi(substring);
        }
    });

    std::cout << name << "@" << domain << ":" << port << "\n"
}

Getting the code

CMake

1. Use execute_process and add_subdirectory. This seems to be the easiest, but if there is a better way, let us know how and submit a patch.::

# Recommend putting this into a `<root>/3rd-party/CMakeLists.txt`

if(NOT EXISTS ${CMAKE_CURRENT_BINARY_DIR}/argreffunc)
    execute_process(
            COMMAND git clone https://github.com/SimplyKnownAsG/argreffunc.git
            WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR})
endif()

add_subdirectory(${CMAKE_CURRENT_BINARY_DIR}/3rd-party/argreffunc/src)

\example Example.cpp here's a thing.

2. Use ``ExternalProject_Add```.

Otherwise

1. Download with wget/curl
2. git clone/cmake -Bbuild -H./cmake --build build --target install
