The Diff Match and Patch libraries offer robust algorithms to perform the operations required for synchronizing plain text.
Compare two blocks of plain text and efficiently return a list of differences.
Given a search string, find its best fuzzy match in a block of plain text. Weighted for both accuracy and location.
Apply a list of patches onto plain text. Use best-effort to apply patch even when the underlying text doesn't match.
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.
Please note you need only the diff_match_patch.js in a production environment the test harness and the uncompressed versions are for debugging purposes only.
