AI Summary

Difftastic 0.69.0 improves syntax understanding by treating trailing punctuation as insignificant and adds support for Assembly, while removing support for the unmaintained Hack language.

Key Highlights

  • Trailing punctuation is now considered non-significant for Go, Java, JS, Python, Rust, Swift, and TypeScript.
  • Added support for Assembly language parsing.
  • Substantially improved parsing for Perl, Clojure, Common Lisp, CSS, Dart, Erlang, F#, OCaml, Rust, Scala, TypeScript, and VHDL.
  • Removed support for Hack language (upstream parser unmaintained).
  • Now considers `.gitattributes` for file type detection.

Breaking Changes

  • Removed support for Hack language parsing. Files starting with `<?hh` will now be treated as text.

New Features

  • Trailing punctuation handling for multiple languages.
  • Assembly language support.
  • Improved parsing for Clojure, Common Lisp, CSS, Dart, Erlang, F#, OCaml, Python, Rust, Scala, TypeScript, and VHDL.
  • `.gitattributes` file detection support.
  • Requires Rust 1.85 or later to build.

Full Release Notes

Difftastic is a structural diff tool that understands syntax. See [the manual](https://difftastic.wilfred.me.uk/) to get started, and [the changelog](https://github.com/Wilfred/difftastic/blob/master/CHANGELOG.md) 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.

Substantially improved parsing for Perl.

Improved parsing for Clojure, Common Lisp, CSS, Dart, Erlang, F#, OCaml, Python, Rust, Scala, TypeScript and VHDL.

Removed support for Hack, as the upstream parser is no longer maintained. `.php` files starting with `<?hh` are now treated as text.

### File Detection

Difftastic now considers `.gitattributes` when deciding if a file is binary, recognising both the `-text` and `binary` attributes.

### Build

Difftastic now requires Rust 1.85 or later to build.
