1.0.21

• Support relocated Nix store
  • If configured through NIX_REMOTE environment variable.
• Compact input derivation diffs
• Fix support for less -R when coloring multiple lines

1.0.20

• Add --context flag
  • This limits the context to the specified number of characters/words/lines
• Bump upper bounds
  • Allow unix-2.8 and few more

1.0.19

• New Haskell API
  • Previously nix-diff only had a command-line API, but now there is a Haskell API available under the Nix.Diff module hierarchy
• Machine-readable output
  • nix-diff now supports a --json flag for machine-readable JSON output
• New --skip-already-compared command-line option
  • This compresses a sub-tree of the diff if the leaves have already been compared
• New --squash-text-diff command-line option
  • This compresses textual diffs into larger spans when possible
• Ignore !${OUTPUT}
  • nix-diff will now strip everything after ! from a derivation argument so that arguments like /nix/store/…!bin no longer fail

1.0.18

• Document the --color command-line option

1.0.17

• Handle .drv and .nix files that contain non-UTF8 text

1.0.16

• Accept realised store paths as input
  • nix-diff will attempt to find the corresponding derivations using nix-store --query --deriver if you provide a realised store path as input

1.0.15

• Fix non-exhaustive pattern match
  • This non-exhaustive pattern match would cause the program to fail if the new derivation added or removed input sources

1.0.14

• Improve whitespace handling

  • --word-oriented now treats all whitespace characters as word boundaries instead of just spaces

    This matches the behavior of Prelude.words

  • --word-oriented no longer highlights the intervening spaces between words

    This is for consistency with --line-oriented, which doesn't highlight the intervening spaces between lines. Also, you could argue that if the user specifies --word-oriented then they want all new tokens to be highlighted on a word-by-word basis.

  • --line-oriented now no longer introduces a trailing newline at the end of a newline-free segment of text

  • More generally, both --word-oriented and --newline-oriented exactly preserve the original whitespace that was used for word or line boundaries.

1.0.13

• Add new --word-oriented mode, which is now the new default mode
  • This now diffs on word boundaries instead of line-boundaries

1.0.12

• Use "patience" diff algorithm
  • This improves the quality of the diff

1.0.11

• Add support for diffing input sources
