> Plugin for [markdown-it](https://github.com/markdown-it/markdown-it) markdown parser, adding emoji & emoticon syntax support.
|
||
|
|
|
||
|
|
__v1.+ requires `markdown-it` v4.+, see changelog.__
|
||
|
|
|
||
|
|
Two versions:
|
||
|
|
|
||
|
|
- __Full__ (default), with all github supported emojis.
|
||
|
|
- [Light](https://github.com/markdown-it/markdown-it-emoji/blob/master/lib/data/light.json), with only well-supported unicode emojis and reduced size.
|
||
|
|
|
||
|
|
Also supports emoticons [shortcuts](https://github.com/markdown-it/markdown-it-emoji/blob/master/lib/data/shortcuts.js) like `:)`, `:-(`, and others. See the full list in the link above.
|
||
|
|
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
node.js, browser:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
npm install markdown-it-emoji --save
|
||
|
|
bower install markdown-it-emoji --save
|
||
|
|
```
|
||
|
|
|
||
|
|
## Use
|
||
|
|
|
||
|
|
### init
|
||
|
|
|
||
|
|
```js
|
||
|
|
var md = require('markdown-it')();
|
||
|
|
var emoji = require('markdown-it-emoji');
|
||
|
|
// Or for light version
|
||
|
|
// var emoji = require('markdown-it-emoji/light');
|
||
|
|
|
||
|
|
md.use(emoji [, options]);
|
||
|
|
```
|
||
|
|
|
||
|
|
Options are not mandatory:
|
||
|
|
|
||
|
|
- __defs__ (Object) - rewrite available emoji definitions
|
||
|
|
- example: `{ name1: char1, name2: char2, ... }`
|
||
|
|
- __enabled__ (Array) - disable all emojis except whitelisted
|
||
|
|
- __shortcuts__ (Object) - rewrite default shortcuts
|
||
|
|
- example: `{ "smile": [ ":)", ":-)" ], "laughing": ":D" }`
|
||
|
|
|
||
|
|
_Differences in browser._ If you load the script directly into the page without
|
||
|
|
using a package system, the module will add itself globally with the name `markdownitEmoji`.
|
||
|
|
Init code will look a bit different in this case:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var md = window.markdownit().use(window.markdownitEmoji);
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
### change output
|
||
|
|
|
||
|
|
By default, emojis are rendered as appropriate unicode chars. But you can change
|
||
|
|
the renderer function as you wish.
|
||
|
|
|
||
|
|
Render as span blocks (for example, to use a custom iconic font):
|
||
|
|
|
||
|
|
```js
|
||
|
|
// ...
|
||
|
|
// initialize
|
||
|
|
|
||
|
|
md.renderer.rules.emoji = function(token, idx) {
|
||
|
|
return '<span class="emoji emoji_' + token[idx].markup + '"></span>';
|
||
|
|
};
|
||
|
|
```
|
||
|
|
|
||
|
|
Or use [twemoji](https://github.com/twitter/twemoji):
|
||
|
|
|
||
|
|
```js
|
||
|
|
// ...
|
||
|
|
// initialize
|
||
|
|
|
||
|
|
var twemoji = require('twemoji')
|
||
|
|
|
||
|
|
md.renderer.rules.emoji = function(token, idx) {
|
||
|
|
return twemoji.parse(token[idx].content);
|
||
|
|
};
|
||
|
|
```
|
||
|
|
|
||
|
|
__NB 1__. Read [twemoji docs](https://github.com/twitter/twemoji#string-parsing)!
|
||
|
|
In case you need more options to change image size & type.
|
||
|
|
|
||
|
|
__NB 2__. When using twemoji you can make image height match the line height with this
|
||
|
|
style:
|
||
|
|
|
||
|
|
```css
|
||
|
|
.emoji {
|
||
|
|
height: 1.2em;
|
||
|
|
}
|
||
|
|
```
