What is Difftastic, a structural diff
Difftastic is a command-line tool that performs structural diffs, comparing files based on their syntax rather than line-by-line. This approach provides more accurate and human-readable diffs, especially when dealing with code formatting changes or wrapper additions. It leverages tree-sitter for parsing various programming languages and file formats, allowing it to identify the actual changes within the code, ignoring formatting differences. Difftastic supports a wide range of languages and file formats, providing a clear visualization of changes, including line numbers from the original files. It is open-source, MIT-licensed, and integrates with Git for easy use in version control workflows. The tool is designed to enhance code review and understanding by focusing on the semantic changes rather than superficial formatting alterations.
