Thanks to all contributors for the improvements below!

Thanks to the many contributors! Particular highlights are

Thanks to @bash's work, delta now automatically detects whether your terminal has a light/dark background (unless you specify with --light or --dark):

@joshtriplett solved the long-standing problem of correctly parsing traditional grep output, e.g. git grep, grep, etc. Until now there had been annoying parse ambiguities related to separator characters in file paths. This is particularly valuable for git grep since it has interesting features such as git grep -W (see https://github.com/dandavison/delta/issues/769)

@imbrish fixed two important bugs and added the ability to set a default language (e.g. for executable shell scripts with no file name suffix)

How 0.16.5 went

0.16.4

Added 3
  • Add `grep-output-type` option to display grep output in ripgrep layout with syntax highlighting, hyperlinks, and navigation
  • Add gruvmax-fang theme
  • Add discord-dark theme
Changed 8
  • Update clap to 4.1
  • Update git2 to 0.16.1
  • Update bitflags to 2.2
  • Switch back to the dirs crate for dependency management
  • Downgrade and pin the bytelines crate
  • Replace deprecated error_chain crate with anyhow
  • Reduce allocations during --show-colors
  • Remove manual line-wrapping
Fixed 4
  • Fix the --show-themes command
  • Fix warning from bat for an unknown syntax theme
  • Fix submodule diff parsing
  • Fix warning highlight for trailing whitespace

It's 6 months since the last release so this one brings quite a few changes. Thanks very much to all contributors, especially @nickelc for a huge number of contributions, and @wescande for his work on improving whitespace highlighting. With this release delta can now display grep output in (hopefully) exactly the same layout that ripgrep does, but adding syntax highlighting, hyperlinks, and navigation. Use ripgrep --json ... | delta for that, or set grep-output-type = ripgrep to get that output style from git grep etc.

This release does not contain binaries for x86_64-unknown-linux-musl, i686-unknown-linux-gnu, arm-unknown-linux-gnueabihf, or aarch64-unknown-linux-gnu because the cross-compilation GitHub Actions jobs were broken at the time of release. I'll issue a follow-up release including them when that's fixed.
