Common Text Transformation Library, CTTL for short, is a set of C++ classes and functions to understand and modify text data. Common Text Transformation Library implementation is based on STL classes and algorithms.

Concept of a substring plays major role in design of the text transformation library. CTTL substring is an object that interacts with fragments of text encapsulated by STL std::basic_string template class.

Template classes cttl::const_edge and cttl::edge, designed for constant and mutable data access, respectively, represent CTTL substrings. Substrings may be compared, inserted, deleted, or replaced across multiple text inputs. If content of text mutates, the substrings adjust their positions accordingly to the change. CTTL guarantees that substrings remain stable with respect to a potentially mutable text.

Within CTTL framework, a substring may be parsed with EBNF-like grammar. CTTL lexical analysis engine generates a stream of substrings corresponding to the parsed symbols. BNF and EBNF grammars can be written directly in C++.

Template meta-programming and operator overloading offer features to write C++ expressions that describe grammar rules. No additional steps of parsing, compiling, or generating source code are required. Compiled CTTL program implements LL(INF)-parser, the recursive-descent parser with infinite lookahead.

What's New in This Release:
