StringMapper-example.cpp

Expands a std::string containing variables like "Hello, ${name}!" to a literal std::string.

Expands a std::string containing variables like "Hello, ${name}!" to a literal std::string. A tool for expanding variables embedded in a std::string to literals. The input variables are provided as a map, which is allowed to change dynamically. The input std::string, issued with parse(), contains the variables as "$key" or "${key}", a format familiar in Unix shell.

StringMapper parses a given std::string, it splits the std::string into segments containing literals and variables in turn. The result is stored in a list of Stringlet:s. The variables are provided to a StringMap by means of a std::map<std::string,T> .
