Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes.

Parsing

Added support for Objective-C and VHDL.

Files starting with <?xml are now parsed as XML.

Fixed a munmap_chunk(): invalid pointer crash on parsing some large files, particularly JSON.

Display

The default display width for tabs has changed to 4.

Fixed an issue where difftastic would sometimes output literal tabs rather than respecting the display width for tabs.

Build

difftastic now requires Rust 1.65 to build.
