What parameter parser libraries are there for C++?

Question

I'd like to pass parameters to my C++ program in the following manner:

./myprog --setting=value

Are there any libraries which will help me to do this easily?

Answer 1

You could try my little options header (166 loc so easily hackable) options.hpp. It is a single header implementation and should do what you ask. It also prints you the help page automatically.
