# Hack
[](https://travis-ci.org/source-foundry/Hack) [](https://github.com/source-foundry/Hack/blob/master/docs/CONTRIBUTORS.md)
### A typeface designed for source code
Hack is designed to be a workhorse typeface for source code. It has deep roots in the libre, open source typeface community and expands upon the contributions of the [Bitstream Vera](https://www.gnome.org/fonts/) & [DejaVu](http://dejavu-fonts.org/wiki/Main_Page) projects. The large x-height + wide aperture + low contrast design make it legible at commonly used source code text sizes with a sweet spot that runs in the 8px - 14px range. The full set of changes to the upstream source are available in the [changelog](CHANGELOG.md).
The project is in active development and we welcome your input and contributions. You may view our design objectives and contributing instructions in [CONTRIBUTING.md](CONTRIBUTING.md).

The font binaries are released under a license that permits unlimited print, desktop, and web use for commercial and non-commercial applications. The source is released in the widely supported UFO source format (an XML formatted typeface source). We support and highly encourage the development of derivative downstream typeface projects from the Hack source. For additional details about licensing, please see [LICENSE.md](LICENSE.md).
## Quick installation
**NOTE ON FONT UPDATES**
*If you are updating your version of Hack, be sure to remove the previously installed version and clear your font cache first to avoid conflicts that can lead to platform-specific rendering errors. Many platforms/distros offer package managers that automate this process. We release a Windows installer to automate the install/update process on the Windows platform. See below for additional details.*
#### Mac OS X and Linux
1. Download the [latest version of Hack][ttf_latest].
2. Extract the files from the archive (`.zip`) and click to open them.
3. Follow the instructions from your operating system.
4. Enjoy!
#### Windows
To simplify the installation process on Windows systems, we've created the [Hack Windows Installer](https://github.com/source-foundry/Hack-windows-installer/releases/latest) which will guide you through the installation process. This installer addresses a number of common rendering issues that occur with font installs/updates on the Windows platform and is the recommended approach for Windows users.
#### Chrome/ChromeOS
To use with [Secure Shell](https://chrome.google.com/webstore/detail/secure-shell/pnhechapfaindjhompbnflcldabbghjo),
edit the following fields in Options:
- font-family: `"Hack"`
- user-css: `https://cdn.jsdelivr.net/font-hack/2.020/css/hack-extended.min.css`
## Package managers
We highly recommend the convenience of a community developed package manager or other auto-updating utility if this is available on your platform. While the package manager releases may be a bit delayed relative to the repository releases, the packages distributed through these package managers were designed to tune and automate font installs and updates on your system. Please note that the Hack project team does not manage/maintain these packages. For installation issues with Hack packages, please contact the package maintainer directly.
We are aware of Hack support in the following package managers (with associated package names):
- **Arch Linux**: `ttf-hack`
- **Chocolatey (Windows)**: `hackfont`
- **Debian**: `fonts-hack-ttf`
- **Fedora / CentOS**: `dnf-plugins-core :: heliocastro/hack-fonts :: hack-fonts`
- **Gentoo Linux**: `media-fonts/hack`
- **Homebrew Cask (OS X)**: `caskroom/fonts/font-hack`
- **OpenSUSE**: `hack-fonts`
- **Ubuntu**: `fonts-hack-ttf`
- **Visual Studio Package Manager**: `hack.font`
Details on package manager use and advanced manual desktop installation options can be found in [INSTALLATION.md](docs/INSTALLATION.md).
## Web font usage
Hack is available in the woff and woff2 web font formats. See [WEBFONT_USAGE.md](docs/WEBFONT_USAGE.md) for more details, or use the snippets below to quickly include Hack via a CDN (thanks to the generous gang at [jsDelivr](https://github.com/jsdelivr/jsdelivr)). **Bold** and *italic* styles are included by default and work out-of-the-box via the `` and `` tags.
#### 1. Add Hack to HTML
Include one of the following in the <head> section of your HTML file:
**Subset web fonts**
```html
```
**Full character set web fonts**
```html
```
#### 2. Add Hack to CSS
```css
pre, code { font-family: Hack, monospace; }
```
## Additional tools for Hack font customization
### Line Spacing Adjustments
**font-line** is a tool that lets you easily modify the default line spacing of Hack (20% UPM). See the [font-line repository](https://github.com/source-foundry/font-line) for more details, and be sure to check out the [line-spacing directory of the repository](https://github.com/chrissimpkins/Hack/tree/master/tools/line-spacing) for shell scripts that automate the entire process across several commonly used line spacing defaults.
