Quoted Strings Library Proposal (Revision 1)

by Beman Dawes

Excerpt:

Character strings enclosed in quotation marks are an element of numerous common data formats (e.g. XML, CSV), yet C++ standard library stream I/O offers no direct support. Furthermore, standard library stream I/O has a problem with embedded spaces in strings that can trip the unwary. The proposed solution provides direct support for quoted strings, avoids embedded spaces problems and is more efficient than likely user provided solutions.

The proposal is suitable for either C++1y or a standard library Technical Specification (TS). It is a pure addition that will break no existing standard-conforming user code. It is based on a Boost component that has been shipping for several years. The declarations for the proposed functions can go in a new header or an existing header.
