repositories, plus a C/C++ color theme.
Features
One-click report: trigger from the Command Palette, the Explorer
context menu, the editor context menu, or the Source Control (SCM) view
Built-in webview: the report opens directly in a VS Code panel, with
draggable panes, view toggling, and synchronized scrolling
Target a path: right-click a file or folder to diff only that path
C/C++ color theme: ships the Symthosm C/C++ light theme with six-color
highlighting for keywords, types, strings, comments, preprocessor directives,
and numbers
Requirements
git available on your PATH
python3 (Linux/macOS) or python (Windows)

Trigger from any of:
Command Palette (Ctrl+Shift+P) → GitDiff: Generate Git Diff HTML Report
Right-click in the Explorer, editor, or Source Control view →
Generate Git Diff HTML Report

By default the report compares the working tree against HEAD. To compare two
commits or staged changes, use the underlying git-diff-html CLI
(https://github.com/LuHaoran1981/GitDiffLocal).
