Simple command line parsing utility.
This is what a basic calculator command line tool might look like
int
run(float a, float b, char const *op) {
// ...
}
int
main(int argc, char const **argv) {
cli::Command program{"calc", "Calculate the sum, difference, product, or division of two numbers"};
cli::Argument<float> arg1{"arg1", "First number"};
cli::Argument<float> arg2{"arg2", "Second number"};
cli::Option<char const *> operation{"--op", "operation", "add"};
program.add_usage(run, arg1, arg2, operation);
return program.run(argc, argv);
}- Automatic delegation: Instead of manually calling
auto arg_value = get_argument("arg1")or some variation, it's just passed to the function provided. - Compile-time sanity check: if the parameters of the function passed in doesn't match the arguments in
add_usage, it will not compile.
