What's Changed

Thanks to all contributors for the changes in this release! One particularly exciting contribution is the tweaks to the highlighting algorithm made by @phillipwood in #1244. This is something that has remained more or less the same since delta was first created, but #1244 brings several improvements in the details of exactly which characters are highlighted.

This release fixes a regression introduced in 0.9.0 affecting the use of git add -p when submodules are present. See https://github.com/dandavison/delta/issues/755

What's Changed

• Do not reformat submodule diffs under git add -p by @dandavison in https://github.com/dandavison/delta/pull/756

Full Changelog: https://github.com/dandavison/delta/compare/0.9.1...0.9.2

This release fixes a security vulnerability (CVE-2021-36376) on Windows. Please update if you are using Windows.

This is a bug fix release: the bug occurs when using delta to diff files whose names contain spaces. It does not affect use of delta as git's pager.

• [closed] 🐛 argument parsing error with delta fileA fileB when filenames contain spaces #644

This is mainly a bug fix release: filenames containing spaces were causing crashes due to a regression in 0.8.0. It also includes a fix for the delta file_a file_b "diff mode" usage style, and an improvement for the diff-highlight / diff-so-fancy emulation modes.

• [closed] 🐛 Panic with filename "01g - Text" #639
• [closed] 🐛 side-by-side option only works in diff mode when piping #631
• [closed] commit-style raw for diff-so-fancy / diff-highlight #623

• 🚀 New option relative-paths causes all file paths to be printed relative to the current directory so that they can be easily opened in a text editor or used in a shell command. Using hunk-header-style = file line-number syntax will emit the line number with the file path and thus should allow your editor to open at the correct line. For example, in the VS Code integrated terminal this means that with no further configuration every file path in git output can be opened with ctrl-click/cmd-click, and opening at a specific line works. Use diff-stat-align-width to control horizontal alignment of diff stat sections, although this may be replaced by a better solution in the future. https://github.com/dandavison/delta/issues/552
• 🚀 New option commit-regex allows delta to work nicely with custom git log formats (https://github.com/dandavison/delta/issues/174)
• 🚀 Support git -c delta.foo=bar ... in latest git version https://github.com/dandavison/delta/pull/573
• 🚀 Support custom hyperlink hash formats #613
• 🚀 Allow custom themes to be defined as light themes #598
• 🚀 Transform file paths to be relative to current directory #552
• 🚀 delta file_A file_B now invokes git diff, instead of diff -u
• [Fixed] 🐛 the --24-bit-color option is unusable from .gitconfig: 24-bit-color is deprecated; use true-color instead. #567
• [Fixed] 🐛 Fix less version parsing (https://github.com/dandavison/delta/pull/606, thanks @tpoliaw)
• [Fixed] 🐛 No output for chmod file mode change #583

This release brings two improvements due to delta contributors:

• @cben proposed a new way for delta to seed less with the regexp that is used to implement navigation, which is implemented in this release. This makes it possible to keep navigate=true in delta config all the time, without the ill effects that it had before (#237)

• @clnoll contributed a new option delta --show-themes, which demos the delta color themes that are available locally. n and N step forwards and backwards through the themes. (https://github.com/dandavison/delta/pull/550)

• @clnoll has also contributed new themes to the growing collection (please consider submitting your own color config as a theme!)

• [closed] 🐛 Setting $PAGER to use delta results in an infinite loop #529

• [closed] 🐛 --navigate breaks git log --oneline and empty git diff #237

To be superseded by 0.7.1

This release brings a new and more convenient way to change delta options in a one-off git command: using git -c. Here's an example:

git -c delta.line-numbers=false -c delta.max-line-distance=0.8 show

Thanks to @wyuenho for pointing out that this should be supported. See https://github.com/dandavison/delta/issues/493 and https://github.com/dandavison/delta/pull/495.

One note: while quotes around color hex codes are required in gitconfig, they can be omitted in the git -c context

git -c delta.plus-style='syntax "#aa0000"' show
git -c delta.plus-style='syntax #aa0000' show

• [closed] 🐛 Hunk header misaligned in some cases #510
• [closed] 🐛 Delta does not respect git -c #493
• [closed] 🚀 Support for Apple Silicon/ARM64 #484
• [closed] 🐛 Can't disable line numbering from command line #307

This release is primarily to make delta build on Apple Silicon/ARM for Homebrew (#487). It also fixes an inconsistency whereby the line number was not displayed in the hunk header if line-numbers was active (https://github.com/dandavison/delta/pull/473#issuecomment-752900940).

This release introduces a cosmetic change to delta output: the line number (when full line-numbers mode is not active) is now displayed in the hunk header line, along with the hunk header code fragment, and optionally a file path. Thanks to @infokiller and @torarnv for suggesting these changes. For example, it might now look like this, if you use hunk-header-style = file line-number syntax:

Use hunk-header-style to configure it:

--hunk-header-style <hunk-header-style>
    Style (foreground, background, attributes) for the hunk-header. See STYLES section. Special attributes
    'file' and 'line-number' can be used to include the file path, and number of first hunk line, in the hunk
    header. If included in the hunk header, 'file' and 'line-number' are styled according to 'file-style' and
    'hunk-header-decoration-style' respectively. The style 'omit' can be used to remove the hunk header section
    from the output [default: line-number syntax]

If you are displaying the file path in the hunk header, you may want to get rid of the main file line. Use file-style = <my-file-color> omit to set the color of the file in the hunk header while deactivating the main file section.

The release also fixes a bug that was introduced in the last release when using delta as a unified diff replacement, i.e. delta file_a file_b. (#463).

• [closed] 🐛 delta 0.4.5 binary release messes up terminal on Ubuntu 20 04 #463
• [closed] 🐛 delta 0.4.5 binary release does not run on macOS 10.11 (El Capitan) #462
• [closed] ReadMe can now use latest less.exe (instead of forked version) #461
• [closed] 🐛 bump-homebrew-formula GitHub CD action is not working #460
• [closed] 🚀 Is it possible to show the file path in the hunk header? #309
• [closed] 🐛 side-by-side alignment incorrect when tabs present #308

Many thanks to @MarcoIeni for creating CI and CD workflows for Delta in GitHub actions, and to @ulwlu for continued work on color-only / git add -p support.

• [closed] delta shall have non-zero status code if there were any matches found #448
• [closed] 🚀 Expose max_buffered_lines as configurable option #427

• [closed] 🐛 Windows Terminal Preview 1.4: Hyperlinks not working #332
• [closed] Is it possible to not use hunk header and see absolute (true) not relative line numbers? #319
• [closed] Is it possible to show the file path in the hunk header? #309
• [closed] 🐛 Markdown coloring problem #281

This release mostly fixes bugs in git add -p behavior, adds test coverage, and clarifies the code involved. Thanks very much @ryuta69 who did all this work.

In addition, a new environment variable is supported: DELTA_PAGER. If set, this takes precedence over BAT_PAGER. See --paging in delta --help.

• [closed] 🐛 git add -p one-to-one correspondence errors #320
• [closed] 🐛 Line numbers incorrect/relative - Windows/Delta 0.4.1 #293
• [closed] 🐛 [Linux] git add -p not working with side-by-side #274
• [closed] 🐛 Delta crash on Windows when using as stand-alone diff tool #339
• [closed] Second document label is missing last character (truncated) #324

A few bug fixes and a couple of minor features (mac-line-length (#154) and the ability to hide all line numbers (#292)).

• [closed] 🚀 How to remove line number #292
• [closed] 🚀 ignore big file diff #288
• [closed] 🐛 Tabs displayed incorrectly under git diff color-moved #280
• [closed] 🚀 Release aarch64 build #278
• [closed] 🐛 Width calculations are incorrect with hyperlinks and side-by-side #262
• [closed] 🐛 High memory usage when fed diff of minimized files #154

This release fixes a few bugs. In particular, it makes it possible to use git add -p with line numbers activated. If you also have side-by-side activated then that will not be used in git add -p (it's impossible) but it will now not cause an error either. Thanks very much to @yoichi for analyzing and fixing the problems with git add -p.

• [closed] 🐛 Dockerfile isn't colored #275
• [closed] 🐛 [Linux] git add -p not working with side-by-side #274
• [closed] 🐛 Mismatch in line numbers between git diff and git add -p #258

The main new feature in this release is support for git diff --color-moved: see #72. This makes Git's native moved-line detection algorithms and styling options available when using Delta. Delta supports this automatically, without any configuration change, but see the new option inspect-raw-lines in case you need to turn it off.

The other new feature is that Delta can now cause files and commit hashes to be rendered as hyperlinks in your terminal emulator: However, this will not be available to you without, at the minimum, installing a patched version of less, because support for the hyperlink spec has only partially spread through the terminal application ecosystem. See #257 and the delta --help text for details.

Finally, thanks to @ryuta69 for the fix for #264.

• [closed] 🚀 Support --color-moved #72
• [closed] 🚀Support --color-moved-ws #144
• [closed] 🚀 Support displaying files and commits as OSC 8 hyperlinks #257
• [closed] 🐛 width option is not honored in git config sections #264
• [closed] 🐛 diff -U0 rendered with lines out of order #263
• [closed] 🐛 paging should be supported in gitconfig #253
• [closed] 🐛 syntax-theme should be honored in a custom feature in gitconfig #252
• [closed] 🐛 Line numbers style not taking effect with --side-by-side #251
• [closed] 🐛 Duplicate "renamed" header when file is renamed with changes #245

This release adds a side-by-side diff view: delta -s or delta --side-by-side. By default, side-by-side view has line-numbers activated, and has syntax highlighting in both the left and right panels.

The release also fixes bug #238 in which the line number display alignment was broken for line numbers greater than 9999.

• [closed] 🚀 directory diff #232
• [closed] 🚀 Side by side viewer #86
• [closed] 🐛 line-number breaks with 5 digits #238

This is a large release, introducing major changes to delta configuration as well as new features and bug fixes. It involved a major overhaul of the code base. Many thanks to everyone who submitted issues, PRs, and helped with testing and feedback, in particular @0xC0FFEE, @boris-petrov, @clnoll, @da-x, @gibfahn, @mk12, @phillipwood, @waldyrious.

The highlights are:

• To configure delta's appearance, you now use "styles" instead of background color names. A style is a string like red bold ul "#ffeeee" that specifies foreground color, background color, and attributes. See https://github.com/dandavison/delta#choosing-colors-styles.

• Delta now reads configuration from a [delta] section in git config, and this is the recommended way to configure delta. See https://github.com/dandavison/delta#configuration

• Delta now has a line numbers feature, thanks to @clnoll. See https://github.com/dandavison/delta/pull/190, https://github.com/dandavison/delta/pull/219

• Delta now has --diff-highlight and --diff-so-fancy emulation modes (thanks @waldyrious for much testing)
