Google Diff Match Patch C

The Diff Match and Patch libraries offer robust algorithms to perform the operations required for synchronizing plain text. Diff: Compare two blocks of plain text and efficiently return a list of differences. Match: Given a search string, find its best fuzzy match in a block of plain text. Weighted for both accuracy and location. Patch: Apply a list of patches onto plain text. Use best-effort to apply patch even when the underlying text doesn't match. Currently available in Java, JavaScript, Dart, C++, C#, Objective C, Lua and Python. Regardless of language, each library features the same API and the same functionality. All versions also have comprehensive test harnesses. Algorithms: This library implements Myer's diff algorithm which is generally considered to be the best general-purpose diff. A layer of pre-diff speedups and post-diff cleanups surround the diff algorithm, improving both performance and output quality. This library also implements a Bitap matching algorithm at the heart of a flexible matching and patching strategy.
