I use Git repositories to manage my patches, but sometimes I feel difficulty maintaining a project in the long term. The commit diff shown in text is not human-readable, therefore it is not straightforward to track multiple changes of a patch.

This motivates me to develop Pure Diff Viewer, a tool to render different commits of a patch and make comparisons. The changes will be highlighted and categorized. The user can ignore unimportant ones (e.g. simple element movements). This tool can either be used as a standalone app or invoked by Git commands.

This project is available at: https://github.com/chsh2/pure-diff-viewer , and I also participated the KVR Developer Challenge 2026 with it. The development is still in an early stage and any feedback is appreciated.
