Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Diffing Improved performance, particularly for line-based diffs or pathological cases (e.g. an extremely long line). Linear diffs (used in line-based diffs and word highlighting) have changed from the Wu-Manber algorithm to the Histogram algorithm. This is a modest…
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Diffing Improved diffing performance, particularly when diffing directories. Parsing Files with parse errors now report the position of the first error, to help investigate issues. Added support for Dockerfiles and Fish shell. Improved support for Dart, Emacs Lisp,…
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Diffing Difftastic now understands when trailing punctuation isn't significant, so foo(1,) and foo(1) are treated as "no syntactic changes". This is supported for Go, Java, JavaScript, Python, Rust, Swift and TypeScript. Parsing Added support for Assembly. Substant…

Updated Ada, Clojure, CMake, Dart, Devicetree, Elisp, Elm, Gleam, HCL, Newick, QML, R, Racket, SQL, Scheme, and Solidity parsers. Improved handling of variable names $foo in shell scripts. Improved detection of YAML…
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Build Incrased the default page size of Jemalloc, so difftastic should work on systems with large page sizes (typically aarch64, i.e. Arm). difftastic now requires Rust 1.75 to build. Parsing Updated Clojure, Common Lisp, Rust and Zig parsers. Improved parsing of K…
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Parsing Updated to the latest tree-sitter parser for Erlang, F#, Gleam, Pascal and Swift. File detection is now stricter for UTF-8, and recognises more compression file types as binary (e.g. zstd or bzip2). Added support for Verilog and SystemVerilog. Build CI on G…
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Diffing When diffing directories, difftastic now ignores the .git directory. Display Fixed an issue where --display=side-by-side-show-both would not use a two-column display when one file was empty. Command Line Interface Difftastic no longer accepts the --missing-…
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Diffing Improved handling of multiline strings, which could cause a crash if they occurred at the end of the file. This was particularly noticeable with YAML. Parsing Improved language detection when one argument is a named pipe. Updated to the latest tree-sitter p…
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Recommended git configuration has changed! Please update your ~/.gitconfig to match the git instructions, regardless of your difftastic version. Display Side-by-side display is now smarter on very wide terminals when the content is narrow. Diffing Fixed a crash (in…
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Diffing Fixed a crash (introduced in 0.59) when the final changed hunk included the last line of the file. Display Fixed an issue where files with no common content would show duplicate hunks. Fixed a performance issue when files had extremely long lines (e.g. 100,…
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes. Diffing Fixed crash on some textual files where a single change contained more than 1,000 words. Parsing Added support for device tree and F#. Difftastic now uses tree-sitter comment highlighing as a hint that nodes should be treated as atoms. This ensures comments…
