</table>
## Installation
```sh
brew tap dandavison/delta https://github.com/dandavison/delta
brew install dandavison/delta/git-delta
```
Alternatively, executables for your platform can be downloaded at https://github.com/dandavison/delta/releases.
## Configure git to use delta
```sh
git config --global core.pager "delta --dark" # --light for light terminal backgrounds
```
Alternatively, you can edit your `.gitconfig` directly. An example is
```
[core]
pager = delta --plus-color="#012800" --minus-color="#340001" --theme="base16-ocean.dark"
```
All git commands that display diff output should now display syntax-highlighted output. For example:
- `git diff`
- `git show`
- `git log -p`
- `git stash show -p`
## Usage
```
USAGE:
delta [FLAGS] [OPTIONS]
FLAGS:
--compare-themes Compare available syntax highlighting themes. To use this option, supply git diff output
to delta on standard input. For example: `git show --color=always | delta --compare-
themes`.
--dark Use colors appropriate for a dark terminal background. For more control, see --theme,
--plus-color, and --minus-color.
-h, --help Prints help information
--highlight-removed Apply syntax highlighting to removed lines. The default is to apply syntax highlighting
to unchanged and new lines only.
--light Use colors appropriate for a light terminal background. For more control, see --theme,
--plus-color, and --minus-color.
--list-languages List supported languages and associated file extensions.
--list-themes List available syntax highlighting themes.
--show-colors Show the command-line arguments for the current colors.
-V, --version Prints version information
OPTIONS:
--commit-style <commit_style>
Formatting style for commit section of git output. Options are: plain, box. [default: plain]
--file-style <file_style>
Formatting style for file section of git output. Options are: plain, box, underline. [default: underline]
--hunk-style <hunk_style>
Formatting style for hunk section of git output. Options are: plain, box. [default: box]
--minus-color <minus_color> The background color (RGB hex) to use for removed lines.
--minus-emph-color <minus_emph_color>
The background color (RGB hex) to use for emphasized sections of removed lines.
--plus-color <plus_color> The background color (RGB hex) to use for added lines.
--plus-emph-color <plus_emph_color>
The background color (RGB hex) to use for emphasized sections of added lines.
--theme <theme> The syntax highlighting theme to use.
-w, --width <width>
The width (in characters) of the background color highlighting. By default, the width is the current
terminal width. Use --width=variable to apply background colors to the end of each line, without right
padding to equal width.
```
## 24 bit color
delta works best if your terminal application supports 24 bit colors. See https://gist.github.com/XVilka/8346728. For example, on macos, iTerm2 works but Terminal.app does not.
If you're using tmux, it's worth checking that 24 bit color is working correctly. For example, run a color test script like [this one](https://gist.githubusercontent.com/lifepillar/09a44b8cf0f9397465614e622979107f/raw/24-bit-color.sh), or the others listed at https://gist.github.com/XVilka/8346728. If you do not see smooth color gradients, see the discussion at [tmux#696](https://github.com/tmux/tmux/issues/696). The short version is you need something like this in your `~/.tmux.conf`:
```
set -ga terminal-overrides ",xterm-256color:Tc"
```
and you may then need to quit tmux completely for it to take effect.
