String Utilities in C++

A couple of utilities for improving string usability

Join

Concatenate the elements of a container with a joining token. Uses ostreams.

Tokenizer/Split

Split a string into a vector of strings. There are two different versions of the tokenizer: normal and escapable. The EscapableTokenizer cannot return string_views, because it may have to doctor the contents.

Cast - Coercing types from strings

In GoogleMock, if you don't want to define an ostream operator for your type, you can define a function PrintTo(T const &, std::ostream*) in the same namespace as T. GoogleMock then uses ADL to find that function and use it to print out the formatted version.
