The C++ String Toolkit (StrTk) Library is a free library that consists of robust, optimized and portable generic string processing algorithms and procedures for the C++ language. The library is designed to be easy to use and integrate within existing code.

The library has the following capabilities:

• Generic string tokenizer and token iterators
• Fast Split routines
• User specified delimiter and splitter policies (simple and regex based etc.)
• Conversions between data and hex and base-64
• In-place removal and replace routines
• Wild-card matching and globbing
• Search and Replace
• Fast token grid and Comma Separated Values (CSV) processing
• Extremely fast String to Integer, Double and other POD conversions
• Extensible string processing templates and algorithms (eg: combinatorics and randomizations)
• Fast and simple-to-use binary serialization
• Seamless integration with STL and Boost
• Easy to use wrappers of common string processing usage patterns
• Single header file solution requires no installation or building

and plenty more...
