Diff, Match and Patch libraries for Plain Text

The Diff Match and Patch libraries offer robust algorithms to perform the operations required for synchronizing plain text.

  1. Diff:
    • Compare two blocks of plain text and efficiently return a list of differences.
    • Diff Demo
  2. Match:
    • Given a search string, find its best fuzzy match in a block of plain text. Weighted for both accuracy and location.
    • Match Demo
  3. Patch:
    • Apply a list of patches onto plain text. Use best-effort to apply patch even when the underlying text doesn't match.
    • Patch Demo

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.
