GumTreeDiff: Open-Source Java Library & Command-Line Tool

GumTreeDiff is an open-source Java library and command-line tool for detecting changes between two versions of source code. It generates detailed diffs that include moved, updated, and deleted code.

What is GumTreeDiff?

GumTreeDiff is an open-source Java library and command-line tool for detecting changes between two versions of source code. It goes beyond line-based diffs to analyze the syntax trees of code files and identify structural differences, including:

  • Code that has been updated or modified
  • Code that has been moved or reordered
  • Code that has been inserted or deleted

By comparing abstract syntax trees, GumTreeDiff can match code even when it has been reformatted or when lines have moved around, providing insightful diffs. It outputs HTML-based reports highlighting the structural differences between the code versions in different colors.

GumTreeDiff can be used as a library integrated into Java applications or through the command-line interface. It supports diffing common programming languages like Java, C, Python, and others. Key features include configurable matching algorithms, command-line options to filter diffs, and ant-based integration.

Overall, GumTreeDiff helps developers quickly understand how source code has changed over time at a structural level beyond line-by-line diffs. It is released under the MIT open-source license.
