C++ Argument Parser

This repository contains a simple C++ header / source file for parsing command line arguments. The syntax for adding command line arguments is as follows.

 #include"argument_parser.h"
ArgumentSet args;
args.AddFlag("help").Description("print help menu").Shorthand('h');
args.AddPositionalArgument("output").Description("output file");
args.AddFlag("other-flag").Description("other flag").Shorthand('f');
args.AddNamedArgument("myarg").Description("my argument").Shorthand('m').Default("default_value");
intmain(int argc, char * argv[]) {
args.Parse(argc, argv);
std::cout << args.GetArgument("myarg").GetValue() << std::endl;
return0;
}

The program takes arguments using the following format

./program -hf --myarg myarg_value output_value

also,

./program -h -f --myarg myarg_value output_value

and

./program output_value

or

./program --myarg myarg_value output_value

etc.
