285- ARM (eg. Raspberry PI)

286- Arch Linux

287- Void Linux

288- FreeBSD

289- MacOS

290

291### From binaries

292

293Check out the [Release page](https://github.com/sharkdp/bat/releases) for

294prebuilt versions of `bat` for many different architectures. Statically-linked

295binaries are also available: look for archives with `musl` in the file name.

296

297### From source

298

299If you want to build `bat` from source, you need Rust 1.35 or

300higher. You can then use `cargo` to build everything:

301

302```bash

303cargo install bat

304```

305

306You may have to install `cmake` and the `libz` development package

307(`libz-dev` or `libz-devel`) in order for the build to succeed.

308

309## Customization

310

311### Highlighting theme

312

313Use `bat --list-themes` to get a list of all available themes for syntax

314highlighting. To select the `TwoDark` theme, call `bat` with the

315`--theme=TwoDark` option or set the `BAT_THEME` environment variable to

316`TwoDark`. Use `export BAT_THEME="TwoDark"` in your shell's startup file to

317make the change permanent. Alternatively, use `bat`s

318[configuration file](https://github.com/sharkdp/bat#configuration-file).

319

320If you want to preview the different themes on a custom file, you can use

321the following command (you need [`fzf`](https://github.com/junegunn/fzf) for this):

322``` bash

323bat --list-themes | fzf --preview="bat --theme={} --color=always /path/to/file"

324```

325

326`bat` looks good on a dark background by default. However, if your terminal uses a

327light background, some themes like `GitHub` or `OneHalfLight` will work better for you.

328You can also use a custom theme by following the

329['Adding new themes' section below](https://github.com/sharkdp/bat#adding-new-themes).

330

331### Output style

332

333You can use the `--style` option to control the appearance of `bat`s output.

334You can use `--style=numbers,changes`, for example, to show only Git changes

335and line numbers but no grid and no file header. Set the `BAT_STYLE` environment

336variable to make these changes permanent or use `bat`s

337[configuration file](https://github.com/sharkdp/bat#configuration-file).

338

339### Adding new syntaxes / language definitions

340

341`bat` uses the excellent [`syntect`](https://github.com/trishume/syntect/)

342library for syntax highlighting. `syntect` can read any

343[Sublime Text `.sublime-syntax` file](https://www.sublimetext.com/docs/3/syntax.html)

344and theme. To add new syntax definitions, do the following.

345

346Create a folder with syntax definition files:

347

348```bash

349mkdir -p "$(bat --config-dir)/syntaxes"

350cd "$(bat --config-dir)/syntaxes"

351

352# Put new '.sublime-syntax' language definition files

353# in this folder (or its subdirectories), for example:

354git clone https://github.com/tellnobody1/sublime-purescript-syntax

355```

356

357Now use the following command to parse these files into a binary cache:

358

359```bash

360bat cache --build

361```

362

363Finally, use `bat --list-languages` to check if the new languages are available.

364

365If you ever want to go back to the default settings, call:

366

367```bash

368bat cache --clear

369```

370

371### Adding new themes

372

373This works very similar to how we add new syntax definitions.

374

375First, create a folder with the new syntax highlighting themes:

376```bash

377mkdir -p "$(bat --config-dir)/themes"

378cd "$(bat --config-dir)/themes"

379

380# Download a theme in '.tmTheme' format, for example:

381git clone https://github.com/greggb/sublime-snazzy

382

383# Update the binary cache

384bat cache --build

385```

386

387Finally, use `bat --list-themes` to check if the new themes are available.

388

389### Using a different pager

390

391`bat` uses the pager that is specified in the `PAGER` environment variable. If this variable is not

392set, `less` is used by default. If you want to use a different pager, you can either modify the

393`PAGER` variable or set the `BAT_PAGER` environment variable to override what is specified in

394`PAGER`.

395

396If you want to pass command-line arguments to the pager, you can also set them via the

397`PAGER`/`BAT_PAGER` variables:

398

399```bash

400export BAT_PAGER="less -RF"

401```

402

403Instead of using environment variables, you can also use `bat`s [configuration file](https://github.com/sharkdp/bat#configuration-file) to configure the pager (`--pager` option).

404

405**Note**: By default, if the pager is set to `less` (and no command-line options are specified),

406`bat` will pass the following command line

407options to the pager: `-R`/`--RAW-CONTROL-CHARS`, `-F`/`--quit-if-one-screen` and `-X`/`--no-init`.

408The first (`-R`) is needed to interpret ANSI colors correctly. The second option (`-F`) instructs

409less to exit immediately if the output size is smaller than the vertical size of the terminal.

410This is convenient for small files because you do not have to press `q` to quit the pager. The

411third option (`-X`) is needed to fix a bug with the `--quit-if-one-screen` feature in old versions

412of `less`. Unfortunately, it also breaks mouse-wheel support in `less`. If you want to enable

413mouse-wheel scrolling, you can either pass just `-R` (as in the example above, this will disable

414the quit-if-one-screen feature), or you can use a recent version of `less` and pass `-RF` which

415will hopefully enable both quit-if-one-screen and mouse-wheel scrolling.

416

417If scrolling still doesn't work for you, you can try to pass the `-S` option in addition.

418

419## Configuration file

420

421`bat` can also be customized with a configuration file. The location of the file is dependent

422on your operating system. To get the default path for your system, call

423```

424bat --config-file

425```

426

427Alternatively, you can use the `BAT_CONFIG_PATH` environment variable to point `bat` to a

428non-default location of the configuration file:

429```bash

430export BAT_CONFIG_PATH="/path/to/bat.conf"

431```

432

433### Format

434

435The configuration file is a simple list of command line arguments. Use `bat --help` to see a full list of possible options and values. In addition, you can add comments by prepending a line with the `#` character.

436

437Example configuration file:

438```bash

439# Set the theme to "TwoDark"

440--theme="TwoDark"

441

442# Show line numbers, Git modifications and file header (but no grid)

443--style="numbers,changes,header"

444

445# Use italic text on the terminal (not supported on all terminals)

446--italic-text=always

447

448# Add mouse scrolling support in less (does not work with older

449# versions of "less")

450--pager="less -FR"

451

452# Use C++ syntax (instead of C) for .h header files

453--map-syntax h:cpp

454

455# Use "gitignore" highlighting for ".ignore" files

456--map-syntax .ignore:.gitignore

457```

458

459## Using `bat` on Windows

460

461`bat` mostly works out-of-the-box on Windows, but a few features may need extra configuration.

462

463### Paging

464

465Windows only includes a very limited pager in the form of `more`. You can download a Windows binary

466for `less` [from its homepage](http://www.greenwoodsoftware.com/less/download.html) or [through

467Chocolatey](https://chocolatey.org/packages/Less). To use it, place the binary in a directory in

468your `PATH` or [define an environment variable](#using-a-different-pager). The [Chocolatey package](#on-windows) installs `less` automatically.

469

470### Colors

471

472Windows 10 natively supports colors in both `conhost.exe` (Command Prompt) and PowerShell since

473[v1511](https://en.wikipedia.org/wiki/Windows_10_version_history#Version_1511_(November_Update)), as

474well as in newer versions of bash. On earlier versions of Windows, you can use

475[Cmder](http://cmder.net/), which includes [ConEmu](https://conemu.github.io/).

476

477**Note:** The Git and MSYS versions of `less` do not correctly interpret colors on Windows. If you

478don’t have any other pagers installed, you can disable paging entirely by passing `--paging=never`

479or by setting `BAT_PAGER` to an empty string.

480

481### Cygwin

482

483`bat` on Windows does not natively support Cygwin's unix-style paths (`/cygdrive/*`). When passed an absolute cygwin path as an argument, `bat` will encounter the following error: `The system cannot find the path specified. (os error 3)`

484

485This can be solved by creating a wrapper or adding the following function to your `.bash_profile` file:

486

487```shell

488bat() {

489 local index

490 local args=("$@")

491 for index in $(seq 0 ${#args[@]}) ; do

492 case "${args[index]}" in

493 -*) continue;;

494 *) [ -e "${args[index]}" ] && args[index]="$(cygpath --windows "${args[index]}")";;

495 esac
