SPARE Parts: A C++ Toolkit for String PAttern REcognition

In this paper, we consider the design and implementation of SPARE Parts, a C++ toolkit for pattern matching. SPARE Parts is the second generation string pattern matching toolkit from the Ribbit Software Systems Inc. and the Eindhoven University of Technology. The toolkit contains implementations of the well-known Knuth-Morris-Pratt, Boyer-Moore, Aho-Corasick and Commentz-Walter algorithms (and their variants). The toolkit is publicly available (though it is not in the public domain and it may not be redistributed) for noncommercial use. A totally re-implemented toolkit, known as SPARE Parts II, is available for commercial licensing from Ribbit Software Systems Inc. In addition to the functionality of SPARE Parts, it contains approximate pattern matchers, regular pattern matchers, multidimensional pattern matchers, and a highly tuned set of foundation classes.
