Releases: Wilfred/difftastic
0.53.1
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes.
Build
Fixed a dependency issue that broke aarch64 builds on older rustc versions.
0.53.0
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 SCSS.
Updated the Kotlin parser and improved handling of Kotlin nullable types.
.snap files (Jest snapshots) are now detected as JavaScript files.
Diffing
Fixed an issue where adding or removing blank lines would be ignored by the textual diffing logic.
Directory diffing now respects .gitignore files.
Directory diffing can now be sorted by path with the --sort-paths option.
Command Line Interface
Added the option --strip-cr. This removes all carriage return characters before diffing, which is helpful when dealing with a mix of Windows and non-Windows flies.
The option --skip-unchanged now has a corresponding environment option DFT_SKIP_UNCHANGED.
Build
Difftastic now requires Rust 1.60 to build.
0.52.0
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 XML and JSONL.
Diffing
Text nodes now get word diffing, consistent with string literals and comments. This is used in languages like HTML and XML that have separate text nodes.
Display
Improved syntax highlighting of constructors (i.e. type names when values are constructed, such as Foo {}).
Improved syntax highlighting for C#.
Build
This release does not provide a prebuilt musl binary, due to a dynamic linking issue with binaries in the release script.
musl remains tested in CI and supported for users, but you will need to compile difftastic from source.
0.51.1
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes.
This is the same code as 0.51.0, but fixes a CI issue so that prebuilt binaries are attached.
Parsing
Updated Bash, Python and Rust parsers.
Display
Added a JSON display option. This is currently unstable, and requires you to set DFT_UNSTABLE. The JSON structure may change in future.
Please give it a try and give feedback on GitHub issues.
Build
Added support for Linux with musl, Linux on aarch64, and macOS on aarch64.
Note that Difftastic already worked on these platforms, but they are now tested in CI and will be included in prebuilt binaries in releases.

0.50.0
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes.
Conflicts
Difftastic now supports parsing files with conflict markers, enabling you to diff the two conflicting file states.
$ difft file_with_conflicts.js
Parsing
Updated Elixir, Erlang, Go, Kotlin and Racket parsers.
Display
Tweaked the colours on the file header, to make metadata less prominent.
Improved styling of file rename information.
Improved syntax hightling for Java built-in types.
Diffing
Fixed an issue with runaway memory usage when the two files input files had a large number of differences.
Build
Difftastic now requires Rust 1.59 to build.
0.49.0
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 LaTeX.
Updated grammars for C, C++ and Java.
Improved parsing of qualified constructors in Haskell.
Difftastic is now stricter about valid UTF-8 and UTF-16, considering more of the file's bytes during filetype detection. This fixes cases where e.g. PDF was sometimes incorrectly considered as UTF-8.
Diffing
Improved handling of delimiters ("nested sliders") in languages that prefer the outer delimiter, such as JSON and Lisps.
Build
Difftastic now requires Rust 1.58 to build.
0.48.0
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes.
Parsing
Updated Scala parser.
Improved parsing of qualified modules and variables in Haskell.
Diffing
Replaced strings now have subword highlighting, consistent with replaced comments. Thanks @amnore!
Fixed an issue with the cost model for comment replacement, leading difftastic to prefer modified comments even when exact comment matches are possible.
Simplified the cost model, which previously had an inconsistent heuristic depending on whether there were multiple items on the same line. This can lead to slightly different items being marked as changed, but on average the results are better.
Display
Improved word highlighting in comments when they contain numbers or hyphens.
Internals
Difftastic's logging is now configured with the environment variable DFT_LOG. This was previously RUST_LOG, which could interfere with users configuring logging for their own development work.

0.47.0
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes.
Language Detection
Fixed an issue where file extensions of the form *.foo.bar (e.g. *.cmake.in) were ignored.
Added an option --override which overrides language detection based on a glob, e.g. --override='*.js:javascript jsx'. See --help for full documentation and more examples.
Removed the --language option. This option was confusing (it took a file extension rather than a language name) and not very useful (it overrode language detection for all files together).
Parsing
Added support for Solidity.
Display
When difftastic is invoked with two file paths, it will now truncate the path shown to the shared common parts. This is particularly helpful when using difftastic with mercurial.
$ difft dir1/foo/bar.py dir2/foo/bar.py
foo/bar.py -- Python
...
0.46.0
Difftastic is a structural diff tool that understands syntax. See the manual to get started, and the changelog for historical changes.
Command Line Interface
Removed the option --missing-as-empty. This is no longer needed as difftastic handles /dev/null gracefully on all platforms.
Parsing
Added support for Ada.
.ino files are now treated as C++.
Improved parsing for TOML.
Updated grammars for Bash, C, C++, C#, Clojure, CMake, Elixir, Go, Java, JavaScript, OCaml, Perl, QML and TypeScript.
Difftastic now prefers treating files as 'mostly UTF-8' or binary rather than UTF-16. Many files can be decoded as UTF-16 without decoding errors but produce nonsense results, so this heuristic seems to work better.
Fixed an issue where difftastic would discard the last newline in a file before diffing. This was most noticeable when doing textual diffs and the last line had changed.
Display
Difftastic no longer uses purple to highlight regions that are missing styling. This was intended as a debug feature, but it in practice it only highlighted trailing whitespace for a few languages.
