cpparg

Yet another single header command line arguments parser.

Example

#include <cpparg/cpparg.h>
#include <filesystem>

int main(int argc, const char** argv) {
    cpparg::parser parser("Example parser");
    parser.title("Some title");
    
    std::string name;
    parser
        .add('n', "name")
        .optional()
        .value_type("STRING")
        .default_value("Bob")
        .description("Bob's name")
        .store(name);
        
    int i;
    parser
        .positional("i")
        .required()
        .description("Positional interger")
        .value_type("INTEGER")
        .store(i);
        
    parser
        .add("delete")
        .optional()
        .value_type("DIR")
        .description("Directory to delete")
        .default_value("/")
        .handle([](std::string_view dir) {
            std::filesystem::remove(dir);
        });
        
    std::vector<int> free_args;
    parser
        .free_arguments("ints")
        .unlimited()
        .store(free_args);
        
    parser.add_help('h', "help");
    parser.parse(argc, argv);
}
