0.27.0

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

Parsing

Added support for Kotlin and TOML.

Fixed an issue with YAML and | block strings.

Updated to the latest upstream C++, C#, Elixir, Go, Haskell, Java, Python, Ruby, Rust and TypeScript parsers.

Diffing

Improved performance in large files when changes are clustered together.

Display

Improved syntax highlighting.

Tabs are now rendered with eight spaces.

Command Line Interface

Difftastic now validates environment variables the same way as arguments. DFT_DISPLAY=no-such-mode will now error rather than silently using the default display mode.

Build

The upstream Haskell parser has been ported from C++14 to pure C. This should allow difftastic to build on platforms with older C++ compilers.
