diffsitter

# diffsitter Plugin Structural diff tool powered by tree-sitter parsers. Compares code by syntax tree instead of raw lines, making reviews cleaner for refactors and reformatting. ## Installation ```bash cargo install diffsitter # or download from https://github.com/afnanenayet/diffsitter/releases ``` ## Basic Usage ```bash # Diff two files (language inferred from extension) diffsitter old.rs new.rs # Explicit language when extension is ambiguous diffsitter --language python before.py after.py # Compare against git HEAD git diffsitter # Side-by-side terminal output diffsitter --display side-by-side file1.go file2.go ``` ## Common Patterns ```bash # Only show changed hunks (suppress unchanged context) diffsitter --context 0 src/main.rs src/main.new.rs # Use in a git alias for semantic diffs git config alias.sdiff '!f() { diffsitter "$1" "$2"; }; f' # Pipe to a pager for large diffs diffsitter large_old.ts large_new.ts | less -R ``` ## Usage Examples - "Show a semantic diff between these two Python files" - "Compare this file to the version on main without whitespace noise" - "Review what actually changed in this refactor" ## SuperCLI ```bash sc diffsitter _ _ old.rs new.rs sc diffsitter _ _ --language kotlin Before.kt After.kt sc plugins learn diffsitter ```
