dandavison/delta: A syntax-highlighting pager for git, diff, grep, and blame output

Install it (the package is called “git-delta” in most package managers, but the executable is just delta) and add this to your ~/.gitconfig:

[core]
    pager = delta

[interactive]
    diffFilter = delta --color-only

[delta]
    navigate = true    # use n and N to move between diff sections

    # delta detects terminal colors automatically; set one of these to disable auto-detection
    # dark = true
    # light = true

[merge]
    conflictstyle = zdiff3

Delta has many features and is very customizable; please see the user manual.

• Language syntax highlighting with the same syntax-highlighting themes as bat
• Word-level diff highlighting using a Levenshtein edit inference algorithm
• Side-by-side view with line-wrapping
• Line numbering
• n and N keybindings to move between files in large diffs, and between diffs in log -p views (--navigate)
• Improved merge conflict display
• Improved git blame display (syntax highlighting; --hyperlinks formats commits as links to hosting provider etc. Supported hosting providers are: GitHub, GitLab, SourceHut, Codeberg)
• Syntax-highlights grep output from rg, git grep, grep, etc
• Support for Git’s --color-moved feature.
• Code can be copied directly from the diff (-/+ markers are removed by default).
• diff-highlight and diff-so-fancy emulation modes
• Commit hashes can be formatted as terminal hyperlinks to the hosting provider page (--hyperlinks).
  File paths can also be formatted as hyperlinks for opening in your OS.
• Stylable box/line decorations to draw attention to commit, file and hunk header sections.
• Style strings (foreground color, background color, font attributes) are supported for >20 stylable elements, using the same color/style language as git
• Handles traditional unified diff output in addition to git output
• Automatic detection of light/dark terminal background

Code evolves, and we all spend time studying diffs. Delta aims to make this both efficient and enjoyable: it allows you to make extensive changes to the layout and styling of diffs, as well as allowing you to stay arbitrarily close to the default git/diff output.

All the syntax-highlighting color themes that are available with bat are available with delta:
