## Get Started
[Install it](https://dandavison.github.io/delta/installation.html) (the package is called "git-delta" in most package managers, but the executable is just `delta`) and add this to your `~/.gitconfig`:
```gitconfig
[core]
pager = delta
[interactive]
diffFilter = delta --color-only
[delta]
navigate = true # use n and N to move between diff sections
light = false # set to true if you're in a terminal w/ a light background color (e.g. the default macOS terminal)
[merge]
conflictstyle = diff3
[diff]
colorMoved = default
```
Delta has many features and is very customizable; please see the [user manual](https://dandavison.github.io/delta/).
## Features
- Language syntax highlighting with the same syntax-highlighting themes as [bat](https://github.com/sharkdp/bat#readme)
- 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](https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda) 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
## 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.

### Side-by-side view
[[User manual](https://dandavison.github.io/delta/side-by-side-view.html)]
```gitconfig
[delta]
side-by-side = true
```
By default, side-by-side view has line-numbers activated, and has syntax highlighting in both the left and right panels: [[config](#side-by-side-view-1)]
<table><tr><td><img width=800px src="https://user-images.githubusercontent.com/52205/87230973-412eb900-c381-11ea-8aec-cc200290bd1b.png" alt="image" /></td></tr></table>
Side-by-side view wraps long lines automatically:
