C++ string template library

Question

I want simple C++ string based template library to replace strings at runtime.

For example, I will use

string template = \"My name is {{name}}\";
         


        

Answer 1

Have you considered a set of inline functions that use ostringstram instead of "string templates"?

inline std::string name_template(const std::string& name)
{
    std::ostringstream os;
    os << "My name is " << name;
    return os.str();
}

There are other alternate approaches if you need more generality. For example a class hierarchy where the base provides a "format" interface and child classes implement it with the appropriate varying implementation.
