Full Changelog: 0.12.0...0.12.1

0.12.0

There's quite a lot in this release, with contributions from 8 different people.

Firstly a breaking change: some deprecated options are no longer supported: in particular plus-color and minus-color. See #914. A description of this change and what you need to do if you're affected by it is below.

Secondly, improvements, including:

• A (much-needed) short help text is now available: use delta -h. Delta is the proud possessor of 100 command-line options, so I think this is going to be helpful.
• git blame output now displays line numbers (thanks to @th1000s)
• Improvements to file and mode labels by @WayneD
• delta now has a user manual: https://dandavison.github.io/delta/. You can even create a PDF copy (print button in upper-right hand corner), and the README is correspondingly now a much easier read with the minimal required setup instructions and an overview of functionality with screenshots.

Finally some bug fixes, including

• File path hyperlinks (e.g. in diff and grep output) were previously sometimes incorrect, especially when delta was invoked from a directory other than the repo root.
• Some fixes to grep output parsing edge cases

Deprecated options no longer supported:

The options affected here have been deprecated for a couple of years; I hope this doesn't cause you any trouble. Here are the details:

The most common case is that you have something like this in your ~/.gitconfig:

[delta]
    plus-color = my_plus_color
    minus-color = my_minus_color

Please change that to

[delta]
    plus-style = syntax my_plus_color
    minus-style = normal my_minus_color

Here's the list of deprecated options with a summary of how to update them:

minus-color             Deprecated: use `minus-style = normal my_background_color`
plus-color              Deprecated: Use `plus-style = syntax my_background_color`
minus-emph-color        Deprecated: use `minus-emph-style = normal my_background_color`
plus-emph-color         Deprecated: Use `plus-emph-style = syntax my_background_color`
highlight-removed       Deprecated: use `minus-style = syntax my_background_color`
commit-color            Deprecated: use `commit-style = my_foreground_color
                                         commit-decoration-style = my_foreground_color`
file-color              Deprecated: use `file-style = my_foreground_color
                                         file-decoration-style = my_foreground_color`
hunk-style              Deprecated: synonym of `hunk-header-decoration-style`
hunk-color              Deprecated: use `hunk-header-style = my_foreground_color
                                         hunk-header-decoration-style = my_foreground_color`
theme                   Deprecated: use `syntax-theme`

0.11.3

• Fix handling of --word-diff and --color-words (#829). Note that line-numbers and side-by-side will be ignored if delta detects that the input was generated by git --word-diff / --color-words.
• DELTA_FEATURES can now be used to add to features specified in ~/.gitconfig. Use a + prefix to do this: an example is DELTA_FEATURES=+side-by-side which will activate side-by-side, in addition to your usual features.
• Store less history file in a better location on Windows. Thanks @rashil2000 for this work!
• Fix performance issue affecting some linux users (#839)

What's Changed

Full Changelog: 0.11.0...0.11.1

0.11.0

This release adds handling of merge conflicts and the "combined" diff format which git uses for merge commits; see the Merge conflicts README section and #189. Please consider setting

[merge]
    conflictstyle = diff3

With that setting, when a merge conflict is encountered, delta will display diffs between the ancestral commit and each of the two merge parents:

0.10.3

• Delta was previously handling --word-diff and --color-words output in a nonsensical way. With this release, delta does not attempt to handle these output types, allowing git's raw output through unchanged. Appropriate handling may be added later. See #152
• When a line is unchanged but paired with a line that has additions/deletions, delta now assigns the unchanged line {plus,minus}-non-emph-style; previously it assigned {plus,minus}-style. This change does not alter visual output by default because by default those two style styles are set to the same value. See #785
• Fixes a bug affecting line numbers in side-by-side mode, see #819

PRs

• Refactor: further isolate side-by-side implementation by @dandavison in #801

0.10.0

New features in this release:

• delta displays output from git grep and rg --json ... | delta with code syntax highlighting and navigate functionality. See README#grep and #774.
• delta displays output from git blame with code syntax highlighting, hyperlinks to commits, and control over formatting. See README#git-blame and #761.
• delta syntax highlights file contents produced by git show $revision:/path/to/file
• delta can apply syntax highlighting and arbitrary styling to the raw colors emitted by git --color-moved. This is done by specifying rules for remapping styles using map-styles. See below, and README#--color-moved-support and #72
• More powerful configuration options: styles can reference other styles, custom styles and custom colors can be defined in gitconfig and reused, and 140 colors can be specified using their standard CSS names. See below.
• New subcommand --show-colors outputs a demo of 140 background colors with syntax highlighting, to help choose background colors.
• New subcommand --parse-ansi takes color input and prints out the corresponding style strings (useful for map-styles)
• Utilities for interrogating the command line of the process that is sending output to delta, added by @th1000s.

Here's an example of using map-styles to assign delta styles (one with syntax highlighting) to the raw color-moved styles output by git. This should allow all git's color-moved options to be rendered using delta styles:

[delta]
    features = my-color-moved-theme

[delta "my-color-moved-theme"]
    git-moved-from-style = bold purple     # An ad-hoc named style (must end in "-style")
    
    map-styles = "my-color-moved-theme.git-moved-from-style => red #cccccc, \
                  bold cyan => syntax #cccccc"
                  
    # we could also have defined git-moved-to-style = bold cyan

To make use of that, you need to know that git is emitting "bold cyan" and "bold purple". But that's not always obvious. To help with that, delta now has a --parse-ansi mode. E.g. git show --color=always | delta --parse-ansi outputs something like this:

As you see above, we can now define named styles in gitconfig and refer to them in places where a style string is expected. We can also define custom named colors in git config, and styles can reference other styles; see the hoopoe theme for an example:

[delta "hoopoe"]
    green = "#d0ffd0"  # ad-hoc named color
    plus-style = syntax hoopoe.green  # refer to named color
    plus-non-emph-style = plus-style  # styles can reference other styles

Additionally, we can now use the 140 color names that are standard in CSS. Use delta --show-colors to get a demo of the available colors, as background colors to see how they look with syntax highlighting:
