Request: separate-compilation option

[cxw42]

Would it be possible to add an option that separately compiles the parser and some of the other detail code that callers don't need? That would speed up compilation quite a bit. Thanks for considering this request!

Example of how this is done in another library: https://github.com/gulrak/filesystem#using-it-as-forwarding-implementation-header

[cxw42]

As an interim step, I was able to write a forwarding header and function using the default template arguments. Here it is in case it helps anyone else:

toml-wrapper.hpp

#include <unordered_map>
#include <vector>

#include "toml/get.hpp"

toml::basic_value<toml::preserve_comments, std::unordered_map, std::vector>
parseTomlFile(std::string fname);

toml-wrapper.cpp

#include "toml.hpp"
#include "toml-wrapper.hpp"

toml::basic_value<toml::preserve_comments, std::unordered_map, std::vector>
parseTomlFile(std::string fname)
{
    return toml::parse(fname);
}

Then client code can include toml-wrapper.hpp but not toml.hpp, and link to toml-wrapper.cpp.
