|
A Hexo plugin that adds emoji support, using [Github Emojis API][ghemojis].
|
|
|
|
Check out the [Emoji Cheat Sheet](http://www.webpagefx.com/tools/emoji-cheat-sheet/) for all the emojis it supports.
|
|
|
|
## Installation
|
|
|
|
``` bash
|
|
$ npm install hexo-filter-github-emojis --save
|
|
```
|
|
|
|
## Options
|
|
|
|
You can configure this plugin in `_config.yml`. Default options:
|
|
|
|
``` yaml
|
|
githubEmojis:
|
|
enable: true
|
|
className: github-emoji
|
|
unicode: false
|
|
localEmojis:
|
|
```
|
|
|
|
The filter will try to download the latest version of [Github Emojis][ghemojis] list. If the network is unavailable or too slow it will use the backup version.
|
|
|
|
- **className** - Image class name. For `:sparkles:` the filter will generate something like this:
|
|
|
|
```html
|
|
<img class="github-emoji" title=":sparkles:" alt=":sparkles:" src="https://assets-cdn.github.com/images/icons/emoji/unicode/2728.png" height="20" width="20">
|
|
```
|
|
|
|
- **unicode** - If you set this option to true, the filter will generate something like this:
|
|
|
|
```html
|
|
<span class="github-emoji" title=":sparkles:" data-src="https://assets-cdn.github.com/images/icons/emoji/unicode/2728.png">✨</span>
|
|
```
|
|
Then you can fallback to image with JavaScript. For example, with jQuery:
|
|
|
|
```javascript
|
|
$('span.github-emoji').each(function (i, emoji) {
|
|
var $emoji = $(emoji)
|
|
var codepoint = $emoji.html()
|
|
$('<img height="20" width="20">')
|
|
.on('error', function () {
|
|
// image loading failed
|
|
$emoji.html(codepoint)
|
|
})
|
|
.prop('alt', $emoji.attr('title'))
|
|
.prop('src', $emoji.data('src'))
|
|
.appendTo($emoji.empty())
|
|
})
|
|
```
|
|
|
|
- **localEmojis** - You can specify your own list. An object or JSON string is valid. The filter will first check the `localEmojis` then fallback to the [Github Emojis][ghemojis] list.
|
|
|
|
For example:
|
|
|
|
```yaml
|
|
githubEmojis:
|
|
localEmojis:
|
|
arrow_left: https://path/to/arrow_left.png
|
|
arrow_right: https://path/to/arrow_right.png
|
|
```
|
|
|
|
If you need to add code points that are not in the Github list, you can do this:
|
|
|
|
```yaml
|
|
githubEmojis:
|
|
localEmojis:
|
|
man_juggling:
|
|
src: https://path/to/man_juggling.png
|
|
codepoints: ["1f939", "2642"]
|
|
arrow_right: https://path/to/arrow_right.png
|
|
```
|
