GumTree

An awesome code differencing tool that you canintegrate with Git!

Status

Description

GumTree is a syntax-aware diff tool. It improves text-based diff tools in two important ways:

the edit actions are always aligned with the syntax,
it can detect moved or renamed elements in addition of deleted and inserted code.

Documentation

To use GumTree, you can start by consulting theGetting Started page from ourwiki. If you have a question to ask, please use GitHub'sdiscussions instead of opening an issue.
