# args

Minimal header-only C++11 argument parser library for simple command line tools.

## Usage

Fetch the project in your CMakeLists.txt:

```cmake

include(FetchContent)

FetchContent_Declare(args

    GIT_REPOSITORY

        "https://github.com/LLVMParty/args"

    GIT_TAG

        v1.2

)

FetchContent_MakeAvailable(args)

```

Then inherit from `ArgumentParser` and add your flags:

```cpp

#include 

#include "args.hpp"

struct Arguments : public ArgumentParser

{

    std::string input;

    std::string output;

    bool        parallel = false;

    Arguments(int argc, const char* const* argv) : ArgumentParser("Example")

    {

        addPositional("input", input, "Input file", true);

        addString("-output", output, "Output file");

        addBool("-parallel", parallel, "Process the input on multiple threads");

        parseOrExit(argc, argv);

    }

};

int main(int argc, char** argv)

{

    Arguments args(argc, argv);

    printf("input: '%s'\n", args.input.c_str());

    printf("output: '%s'\n", args.output.c_str());

    printf("parallel: %s\n", args.parallel ? "yes" : "no");

    return EXIT_SUCCESS;

}

```
