# GitHub Octicons
|
|||
|
|
|
|||
|
|
[](https://www.npmjs.org/package/octicons)
|
|||
|
|
[](https://travis-ci.org/primer/octicons)
|
|||
|
|
|
|||
|
|
> Octicons are a scalable set of icons handcrafted with <3 by GitHub.
|
|||
|
|
|
|||
|
|
## Install
|
|||
|
|
|
|||
|
|
**NOTE:** The compiled files are located in `build/`. This directory is located in the published npm package. Which means you can access it when you `npm install octicons`. You can also build this directory by following the [building octicons directions](#building-octicons). The files in the `lib/` directory are the raw source files and are not compiled or optimized.
|
|||
|
|
|
|||
|
|
#### npm
|
|||
|
|
|
|||
|
|
This repository is distributed with [npm][npm]. After [installing npm][install-npm], you can install `octicons` with this command.
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
$ npm install octicons --save
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Usage
|
|||
|
|
|
|||
|
|
For all the usages, we recommend using the CSS located in `build/octicons.css`. This is some simple CSS to normalize the icons and inherit colors.
|
|||
|
|
|
|||
|
|
### Spritesheet
|
|||
|
|
|
|||
|
|
With an [SVG sprite icon system](https://css-tricks.com/svg-sprites-use-better-icon-fonts/) you can include the sprite sheet located `build/sprite.octicons.svg` after you [build the icons](#building-octicons) or from the npm package. There is a demo of how to use the spritesheet in the `build/` directory also.
|
|||
|
|
|
|||
|
|
### Node
|
|||
|
|
|
|||
|
|
After installing `npm install octicons` you can access the icons like this.
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
var octicons = require("octicons")
|
|||
|
|
octicons.alert
|
|||
|
|
// { keywords: [ 'warning', 'triangle', 'exclamation', 'point' ],
|
|||
|
|
// path: '<path d="M8.865 1.52c-.18-.31-.51-.5-.87-.5s-.69.19-.87.5L.275 13.5c-.18.31-.18.69 0 1 .19.31.52.5.87.5h13.7c.36 0 .69-.19.86-.5.17-.31.18-.69.01-1L8.865 1.52zM8.995 13h-2v-2h2v2zm0-3h-2V6h2v4z"/>',
|
|||
|
|
// height: '16',
|
|||
|
|
// width: '16',
|
|||
|
|
// symbol: 'alert',
|
|||
|
|
// options:
|
|||
|
|
// { version: '1.1',
|
|||
|
|
// width: '16',
|
|||
|
|
// height: '16',
|
|||
|
|
// viewBox: '0 0 16 16',
|
|||
|
|
// class: 'octicon octicon-alert',
|
|||
|
|
// 'aria-hidden': 'true' },
|
|||
|
|
// toSVG: [Function] }
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
There will be a key for every icon, with [`toSVG`](#octiconsalerttosvg) and other properties.

|
#### `octicons.alert.symbol`

|
|||
|
|
// <svg version="1.1" width="45" height="60" viewBox="0 0 12 16" class="octicon octicon-x" aria-hidden="true"><path d="M7.48 8l3.75 3.75-1.48 1.48L6 9.48l-3.75 3.75-1.48-1.48L4.52 8 .77 4.25l1.48-1.48L6 6.52l3.75-3.75 1.48 1.48z"/></svg>

|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
octicons.x.toSVGUse()
|
|||
|
|
// <svg version="1.1" width="12" height="16" viewBox="0 0 12 16" class="octicon octicon-x" aria-hidden="true"><use xlink:href="#x" /></svg>
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
### Ruby
|
|||
|
|
|
|||
|
|
If your environment is Ruby on Rails, we have an [octicons_helper](https://github.com/primer/octicons_helper) gem available that renders SVG in your page. The octicons_helper uses the [octicons_gem](https://github.com/primer/octicons_gem) to do the computing and reading of the SVG files.
|
|||
|
|
|
|||
|
|
### Jekyll
|
|||
|
|
|
|||
|
|
For jekyll, there's a [jekyll-octicons](https://github.com/primer/jekyll-octicons) plugin available. This works exactly like the octicons_helper.
|
|||
|
|
|
|||
|
|
## Changing, adding, or deleting icons
|
|||
|
|
|
|||
|
|
1. Open the [Sketch document][sketch-document] in `lib/`. Each icon exists as an artboard within our master Sketch document. If you’re adding an icon, duplicate one of the artboards and add your shapes to it. Be sure to give your artboard a name that makes sense.
|
|||
|
|
2. Once you’re happy with your icon set, choose File > Export…
|
|||
|
|
3. Choose all the artboards you’d like to export and then press “Export”
|
|||
|
|
4. Export to `lib/svg/`
|
|||
|
|
|
|||
|
|
You’ll next need to build your Octicons.
|
|||
|
|
|
|||
|
|
## Building Octicons
|
|||
|
|
|
|||
|
|
All the files you need will be in the `build/` directory already, but if you’ve made changes to the `lib/` directory and need to regenerate, follow these steps:
|
|||
|
|
|
|||
|
|
1. Open the Octicons directory in Terminal
|
|||
|
|
2. `npm install` to install all dependencies for the project.
|
|||
|
|
3. Run the command `npm run build`. This will run the grunt task to build the SVGs, placing them in the `build/` directory.
|
|||
|
|
|
|||
|
|
## Publishing
|
|||
|
|
|
|||
|
|
If you have access to publish this repository, these are the steps to publishing. If you need access, contact [#design-systems](https://github.slack.com/archives/design-systems).
|
|||
|
|
|
|||
|
|
1. Update the [CHANGELOG.md](./CHANGELOG.md) with relevant version number and any updates made to the repository.
|
|||
|
|
2. `npm version <newversion>` Run [npm version](https://docs.npmjs.com/cli/version) inputing the relevant version type. The versioning is [semver](http://semver.org/), so version appropriately based on what has changed.
|
|||
|
|
3. `npm publish` This will publish the new version to npmjs.org
|
|||
|
|
4. `git push && git push --tags` Push all these changes to origin.
