## Installation

This script is a part of the `bat-extras` suite of scripts. You can find install instructions [here](../README.md#installation).



## Caveats

**When using `bat` as the printer:**

- Syntax highlighting in diffs between two files is not supported.
- Syntax highlighting in a single-file diff requires `bat` >= 0.15.

**When using `delta` as the printer:**

- The `--no-color` option does not remove all color output.
