edncxx

edn for c++ - an experimental work in progress.

see https://github.com/edn-format/edn

Warning

Just getting started on this, do not use for anything at all just yet.

Premise

we want to be able to parse EDN without having to inject a bunch of blabbery types into the c++ source code.

c++17 introduced std::any, which we leverage.

std::variant<...> was tried, with ugly results surrounding the type recursion.

The goal is to have std::any be the bearer of an EDN value.

Since it can also be the bearer of anything, we need to be able to narrow it to some known types.

edncxx::value = [a constrained] std::any which can be of:

• edncxx::nil
• edncxx::bool
• edncxx::string
• edncxx::char
• edncxx::symbol
• edncxx::keyword
• edncxx::integer
• edncxx::float
• edncxx::tagged
• edncxx::list = std::list<edncxx::value>
• edncxx::vector = std::vector<edncxx::value>
• edncxx::map = std::unordered_map<edncxx::value,edncxx::value>
• edncxx::set = std::unordered_set<edncxx::value>

or, at least, that's the idea.....
