    Get Started

    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
        dark = true      # or light = true, or omit for auto-detection
    
    [merge]
        conflictStyle = zdiff3
    

    Or run:

    git config --global core.pager delta
    git config --global interactive.diffFilter 'delta --color-only'
    git config --global delta.navigate true
    git config --global merge.conflictStyle zdiff3
    

    Delta has many features and is very customizable; please see delta -h (short help) or delta --help (full manual), or the online user manual.

    Features

    • 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

    A syntax-highlighting pager for git, diff, and grep output

    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.
