0.5.1

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 (#473 (comment)).

0.5.0

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).

0.4.4

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] Second document label is missing last character (truncated) #324

0.4.3

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

0.4.1

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

0.4.0

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

0.3.0

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

0.2.0

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 #190, #219

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