Pure Diff Viewer by chsh2

Pure Diff Viewer aims at facilitating the version control of Pure Data (Pd), a visual programming language for computer music. When organizing Pd patches in a Git repository, the differences between commits are shown in plain text. The text is hardly human-readable and makes it difficult to track the changes of a patch and maintain it in the long term.

This program attempts to solve this problem by visualizing the differences and rendering them in the Pd node graph. It has the following features:

• Graphical browser of a Git repository of Pure Data (Pd) patches
  • Switches between multiple branches/commits to trace the changes of a patch.
  • Highlights and categorizes patch changes in a semantic way with visual marks.
• Integration with git difftool
  • Supports file/directory comparisons via git commands.
