diffnav

diffnav [options] [commitrange_]

diffnav is a git diff pager that provides an interactive file tree interface for navigating code changes. It combines the functionality of traditional diff viewers with a visual file explorer, making it easier to browse large changesets across multiple files.
The tool integrates with git to show file-by-file differences with syntax highlighting, collapsible sections, and keyboard navigation. It's particularly useful when reviewing pull requests or browsing commits that touch many files.

Requires git to be installed and accessible in PATH. Large repositories may experience slower loading times. Syntax highlighting depends on file extension detection. Some terminal emulators may have limited color support.

diffnav was developed to improve the git diff browsing experience by adding a visual file tree component to the traditional pager interface, making it easier to understand the scope of changes across multiple files.
