About Difftastic
Difftastic is a structural diff tool that compares files based on their syntax tree rather than plain text lines. Using tree-sitter parsers, it understands the structure of over 30 programming languages and shows meaningful diffs that ignore formatting changes. Integrates with Git as a difftool for dramatically cleaner code reviews.
Frequently Asked Questions
How does Difftastic differ from regular diff?
Regular diff compares files line by line as plain text. Difftastic parses the syntax tree of each file and shows differences at the structural level, ignoring cosmetic changes like whitespace.
How do I use Difftastic with Git?
Configure Git to use Difftastic with: git config --global diff.external difft. Or set GIT_EXTERNAL_DIFF=difft for a single command.
What languages does Difftastic support?
Difftastic supports over 30 languages including Python, JavaScript, TypeScript, Rust, Go, Java, C, C++, Ruby, Erlang, Swift, and more via tree-sitter parsers.
Does Difftastic work inside editors?
Difftastic is a command-line tool and integrates primarily with Git. Editor support depends on individual plugins for your editor of choice.
