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 parser for Bash, C, C++, C#, CSS, Go, Haskell, HTML, Java, JavaScript, JSON, Julia, Lua, Objective-C, OCaml, PHP, Python, Ruby, Scala, TOML, TypeScript and XML.
Syntax Highlighting
Improved syntax highlighting, particularly for keywords.
Build
difftastic now requires Rust 1.74.1 to build.
Prebuilt packages for macOS on x86-64 are now built on macOS 13.
