Difftastic0.72.0

Compare two files with Difftastic by their syntax, so the output centers on structural changes rather than raw character sequences. This helps reveal what actually changed when rearranged code, formatting edits, or nested additions would make a line-oriented diff noisy or misleading. Difftastic is a command-line program, making it suitable for developers examining source changes directly or incorporating structural comparisons into a Git workflow.

It parses code with tree-sitter and produces diffs designed to be accurate and readable for humans. If a formatter splits one expression across several lines, it can recognize unchanged inner content instead of reporting a wholesale change. When a wrapper is added, it matches the delimiters and can still isolate the added wrapper even when the enclosed content changes too.

The display uses the actual line numbers from each file, before and after the change, rather than relying on unfamiliar hunk notation alone. It handles supported programming languages and file formats, with the complete language and format coverage described in its manual. Version 0.72.0 is published by Wilfred Hughes for Windows, and the freeware is distributed under the MIT license.
