How to type emoji on Linux
|
||||
======
|
||||
The GNOME desktop makes it easy to use emoji in your communications.
|
||||
![A cat under a keyboard.][1]
|
||||
|
||||
Emoji are those fanciful pictograms that snuck into the Unicode character space. They're all the rage online, and people use them for all kinds of surprising things, from signifying reactions on social media to serving as visual labels for important file names. There are many ways to enter Unicode characters on Linux, but the GNOME desktop makes it easy to find and type an emoji.
|
||||
|
||||
![Emoji in Emacs][2]
|
||||
|
||||
### Requirements
|
||||
|
||||
For this easy method, you must be running Linux with the [GNOME][3] desktop.
|
||||
|
||||
You must also have an emoji font installed. There are many to choose from, so do a search for _emoji_ using your favorite software installer application or package manager.
|
||||
|
||||
For example, on Fedora:
|
||||
|
||||
|
||||
```
|
||||
$ sudo dnf search emoji
|
||||
emoji-picker.noarch : An emoji selection tool
|
||||
unicode-emoji.noarch : Unicode Emoji Data Files
|
||||
eosrei-emojione-fonts.noarch : A color emoji font
|
||||
twitter-twemoji-fonts.noarch : Twitter Emoji for everyone
|
||||
google-android-emoji-fonts.noarch : Android Emoji font released by Google
|
||||
google-noto-emoji-fonts.noarch : Google “Noto Emoji” Black-and-White emoji font
|
||||
google-noto-emoji-color-fonts.noarch : Google “Noto Color Emoji” colored emoji font
|
||||
[...]
|
||||
```
|
||||
|
||||
On Ubuntu or Debian, use **apt search** instead.
|
||||
|
||||
I'm using [Google Noto Color Emoji][4] in this article.
|
||||
|
||||
### Get set up
|
||||
|
||||
To get set up, launch GNOME's Settings application.
|
||||
|
||||
1. In Settings, click the **Region & Language** category in the left column.
|
||||
2. Click the plus symbol (**+**) under the **Input Sources** heading to bring up the **Add an Input Source** panel.
|
||||
|
||||
|
||||
|
||||
![Add a new input source][5]
|
||||
|
||||
3. In the **Add an Input Source** panel, click the hamburger menu at the bottom of the input list.
|
||||
|
||||
|
||||
|
||||
![Add an Input Source panel][6]
|
||||
|
||||
4. Scroll to the bottom of the list and select **Other**.
|
||||
5. In the **Other** list, find **Other (Typing Booster)**. (You can type **boost** in the search field at the bottom to filter the list.)
|
||||
|
||||
|
||||
|
||||
![Find Other \(Typing Booster\) in inputs][7]
|
||||
|
||||
6. Click the **Add** button in the top-right corner of the panel to add the input source to GNOME.
|
||||
|
||||
|
||||
|
||||
Once you've done that, you can close the Settings window.
|
||||
|
||||
#### Switch to Typing Booster
|
||||
|
||||
You now have a new icon in the top-right of your GNOME desktop. By default, it's set to the two-letter abbreviation of your language (**en** for English, **eo** for Esperanto, **es** for Español, and so on). If you press the **Super** key (the key with a Linux penguin, Windows logo, or Mac Command symbol) and the **Spacebar** together on your keyboard, you will switch input sources from your default source to the next on your input list. In this example, you only have two input sources: your default language and Typing Booster.
|
||||
|
||||
Try pressing **Super**+**Spacebar** together and watch the input name and icon change.
|
||||
|
||||
#### Configure Typing Booster
|
||||
|
||||
With the Typing Booster input method active, click the input sources icon in the top-right of your screen, select **Unicode symbols and emoji predictions**, and set it to **On**.
|
||||
|
||||
![Set Unicode symbols and emoji predictions to On][8]
|
||||
|
||||
This makes Typing Booster dedicated to typing emoji, which isn't all Typing Booster is good for, but in the context of this article it's exactly what is needed.
|
||||
|
||||
### Type emoji
|
||||
|
||||
With Typing Booster still active, open a text editor like Gedit, a web browser, or anything that you know understands Unicode characters, and type "_thumbs up_." As you type, Typing Booster searches for matching emoji names.
|
||||
|
||||
![Typing Booster searching for emojis][9]
|
||||
|
||||
To leave emoji mode, press **Super**+**Spacebar** again, and your input source goes back to your default language.
|
||||
|
||||
### Switch the switcher
|
||||
|
||||
If the **Super**+**Spacebar** keyboard shortcut is not natural for you, then you can change it to a different combination. In GNOME Settings, navigate to **Devices** and select **Keyboard**.
|
||||
|
||||
In the top bar of the **Keyboard** window, search for **Input** to filter the list. Set **Switch to next input source** to a key combination of your choice.
|
||||
|
||||
![Changing keystroke combination in GNOME settings][10]
|
||||
|
||||
### Unicode input
|
||||
|
||||
The fact is, keyboards were designed for a 26-letter (or thereabouts) alphabet along with as many numerals and symbols. ASCII has more characters than what you find on a typical keyboard, to say nothing of the millions of characters within Unicode. If you want to type Unicode characters into a modern Linux application but don't want to switch to Typing Booster, then you can use the Unicode input shortcut.
|
||||
|
||||
1. With your default language active, open a text editor like Gedit, a web browser, or any application you know accepts Unicode.
|
||||
2. Press **Ctrl**+**Shift**+**U** on your keyboard to enter Unicode entry mode. Release the keys.
|
||||
3. You are currently in Unicode entry mode, so type a number of a Unicode symbol. For instance, try **1F44D** for a 👍 symbol, or **2620** for a ☠ symbol. To get the number code of a Unicode symbol, you can search the internet or refer to the [Unicode specification][11].
|
||||
|
||||
|
||||
|
||||
### Pragmatic emoji-ism
|
||||
|
||||
Emoji are fun and expressive. They can make your text unique to you. They can also be utilitarian. Because emoji are Unicode characters, they can be used anywhere a font can be used, and they can be used the same way any alphabetic character can be used. For instance, if you want to mark a series of files with a special symbol, you can add an emoji to the name, and you can filter by that emoji in Search.
|
||||
|
||||
![Labeling a file with emoji][12]
|
||||
|
||||
Use emoji all you want because Linux is a Unicode-friendly environment, and it's getting friendlier with every release.

如何在 Linux 系统中输入 emoji
|
||||
======
|
||||
使用 GNOME 桌面可以让你在文字中轻松加入 emoji。
|
||||
|
||||
![A cat under a keyboard.][1]
|
||||
|
||||
emoji 是潜藏在 Unicode 字符空间里的有趣表情图，它们已经风靡于整个互联网。emoji 可以用来在社交媒体上表示自己的心情状态，也可以作为重要文件名的视觉标签，总之它们的各种用法层出不穷。在 Linux 系统中有很多种方式可以输入 Unicode 字符，但 GNOME 桌面能让你更轻松地查找和输入 emoji。
|
||||
|
||||
![Emoji in Emacs][2]
|
||||
|
||||
### 准备工作
|
||||
|
||||
首先，你需要一个运行 [GNOME][3] 桌面的 Linux 系统。
|
||||
|
||||
同时还需要安装一款支持 emoji 的字体。符合这个要求的字体有很多，使用你喜欢的软件包管理器直接搜索 `emoji` 并选择一款安装就可以了。
|
||||
|
||||
例如在 Fedora 上：
|
||||
|
||||
|
||||
```
|
||||
$ sudo dnf search emoji
|
||||
emoji-picker.noarch : An emoji selection tool
|
||||
unicode-emoji.noarch : Unicode Emoji Data Files
|
||||
eosrei-emojione-fonts.noarch : A color emoji font
|
||||
twitter-twemoji-fonts.noarch : Twitter Emoji for everyone
|
||||
google-android-emoji-fonts.noarch : Android Emoji font released by Google
|
||||
google-noto-emoji-fonts.noarch : Google “Noto Emoji” Black-and-White emoji font
|
||||
google-noto-emoji-color-fonts.noarch : Google “Noto Color Emoji” colored emoji font
|
||||
[...]
|
||||
```
|
||||
|
||||
对于 Ubuntu 或者 Debian，需要使用 `apt search`。
|
||||
|
||||
在这篇文章中，我会使用 [Google Noto Color Emoji][4] 这款字体为例。
|
||||
|
||||
### 设置
|
||||
|
||||
要开始设置，首先打开 GNOME 的设置面板。
|
||||
|
||||
1. 在左边侧栏中，选择“<ruby>地区与语言<rt>Region & Language</rt></ruby>”类别
|
||||
2. 点击“<ruby>输入源<rt>Input Sources</rt></ruby>”选项下方的加号（+）打开“<ruby>添加输入源<rt>Add an Input Source</rt></ruby>”面板
|
||||
|
||||
|
||||
|
||||
![Add a new input source][5]
|
||||
|
||||
3. 在“<ruby>添加输入源<rt>Add an Input Source</rt></ruby>”面板中，点击底部的菜单按钮
|
||||
|
||||
|
||||
|
||||
![Add an Input Source panel][6]
|
||||
|
||||
4. 滑动到列表底部并选择“<ruby>其它<rt>Other</rt></ruby>”
|
||||
5. 在“<ruby>其它<rt>Other</rt></ruby>”列表中，找到“<ruby>其它<rt>Other</rt></ruby>（<ruby>快速输入<rt>Typing Booster</rt></ruby>）”
|
||||
|
||||
|
||||
|
||||
![Find Other \(Typing Booster\) in inputs][7]
|
||||
|
||||
6. 点击右上角的“<ruby>添加<rt>Add</rt></ruby>”按钮，将输入源添加到 GNOME 桌面
|
||||
|
||||
|
||||
|
||||
以上操作完成之后，就可以关闭设置面板了。
|
||||
|
||||
#### 切换到快速输入
|
||||
|
||||
现在 GNOME 桌面的右上角会出现一个新的图标，一般情况下是当前语言的双字母缩写（例如英语是 en，世界语是 eo，西班牙语是 es，等等）。如果你按下了<ruby>超级键<rt>Super key</rt></ruby>（也就是键盘上带有 Linux 企鹅/Windows 徽标/Mac Command 标志的键）+空格键的组合键，就会切换到输入列表中的下一个输入源。在这里，我们只有两个输入源，也就是默认语言和快速输入。
|
||||
|
||||
你可以尝试使用一下这个组合键，观察图标的变化。
|
||||
|
||||
#### 配置快速输入
|
||||
|
||||
在快速输入模式下，点击右上角的输入源图标，选择“<ruby>Unicode 符号和 emoji 联想<rt>Unicode symbols and emoji predictions</rt></ruby>”选项，设置为“<ruby>开<rt>On</rt></ruby>”。
|
||||
|
||||
![Set Unicode symbols and emoji predictions to On][8]
|
||||
|
||||
现在快速输入模式已经可以输入 emoji 了。这正是我们现在所需要的，当然快速输入模式的功能也并不止于此。
|
||||
|
||||
### 输入 emoji
|
||||
|
||||
在快速输入模式下，打开一个文本编辑器，或者网页浏览器，又或者是任意一种支持输入 Unicode 字符的软件，输入“thumbs up”，快速输入模式就会帮你迅速匹配的 emoji 了。
|
||||
|
||||
![Typing Booster searching for emojis][9]
|
||||
|
||||
要退出 emoji 模式，只需要再次使用超级键+空格键的组合键，输入源就会切换回你的默认输入语言。
|
||||
|
||||
### 使用其它切换方式
|
||||
|
||||
如果你觉得超级键+空格键这个组合用起来不顺手，你也可以换成其它键的组合。在 GNOME 设置面板中选择“<ruby>设备<rt>Device</rt></ruby>”→“<ruby>键盘<rt>Keyboard</rt></ruby>”。
|
||||
|
||||
在“<ruby>键盘<rt>Keyboard</rt></ruby>”页面中，将“<ruby>切换到下一个输入源<rt>Switch to next input source</rt></ruby>”更改为你喜欢的组合键。
|
||||
|
||||
![Changing keystroke combination in GNOME settings][10]
|
||||
|
||||
### 输入 Unicode
|
||||
|
||||
实际上，现代键盘的设计只是为了输入 26 个字母以及尽可能多的数字和符号。但 ASCII 字符的数量已经比键盘上能看到的字符多得多了，遑论上百万个 Unicode 字符。因此，如果你想要在 Linux 应用程序中输入 Unicode，但又不想使用快速输入，你可以尝试一下 Unicode 输入。
|
||||
|
||||
1. 打开任意一种支持输入 Unicode 字符的软件，但仍然使用你的默认输入语言
|
||||
2. 使用 ctrl+shift+U 组合键进入 Unicode 输入模式
|
||||
3. 在 Unicode 输入模式下，只需要输入某个 Unicode 字符的对应序号，就实现了对这个 Unicode 字符的输入。例如 `1F44D` 对应的是 👍，而 `2620` 则对应了 ☠。想要查看所有 Unicode 字符的对应序号，可以参考 [Unicode 规范][11]。
|
||||
|
||||
|
||||
|
||||
### emoji 的实用性
|
||||
|
||||
emoji 可以让你的文本变得与众不同，这就是它们有趣和富有表现力的体现。同时 emoji 也有很强的实用性，因为它们本质上是 Unicode 字符，在很多支持自定义字体的地方都可以用到它们，而且跟使用其它常规字符没有什么太大的差别。因此，你可以使用 emoji 来对不同的文件做标记，在搜索的时候就可以使用 emoji 把这些文件快速筛选出来。
|
||||
|
||||
![Labeling a file with emoji][12]
|
||||
|
||||
你可以在 Linux 中尽情地使用 emoji，因为 Linux 是一个对 Unicode 友好的环境，未来也会对 Unicode 有着越来越好的支持。
