Ulauncher: A Super Useful Application Launcher for Linux
|
|
||||||
======
|
|
||||||
|
|
||||||
_**Brief:**_ _Ulauncher is a fast application launcher with extension and shortcut support to help you quickly access application and files in Linux._
|
|
||||||
|
|
||||||
An application launcher lets you quickly access or open an app without hovering over the application menu icons.
|
|
||||||
|
|
||||||
By default, I found the application launcher with Pop!_OS super handy. But, not every Linux distribution offers an application launcher out-of-the-box.
|
|
||||||
|
|
||||||
Fortunately, there is a solution with which you can add the application launcher to most of the popular distros out there.
|
|
||||||
|
|
||||||
### Ulauncher: Open Source Application Launcher
|
|
||||||
|
|
||||||
![][1]
|
|
||||||
|
|
||||||
Ulauncher is a quick application launcher built using Python while utilizing GTK+.
|
|
||||||
|
|
||||||
It gives a decent amount of customization and control options to tweak. Overall, you can adjust its behavior and experience to suit your taste.
|
|
||||||
|
|
||||||
Let me highlight some of the features that you can expect with it.
|
|
||||||
|
|
||||||
### Ulauncher Features
|
|
||||||
|
|
||||||
The options that you get with Ulauncher are super accessible and easy to customize. Some key highlights include:
|
|
||||||
|
|
||||||
* Fuzzy search algorithm, which lets you find applications even if you misspell them
|
|
||||||
* Remembers your last searched application in the same session
|
|
||||||
* Frequently used apps display (optional)
|
|
||||||
* Custom color themes
|
|
||||||
* Preset color themes that include a dark theme
|
|
||||||
* Shortcut to summon the launcher can be easily customized
|
|
||||||
* Browse files and directories
|
|
||||||
* Support for extensions to get extra functionality (emoji, weather, speed test, notes, password manager, etc.)
|
|
||||||
* Shortcuts for browsing sites like Google, Wikipedia, and Stack Overflow
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
It provides almost every helpful ability that you may expect in an application launcher, and even better.
|
|
||||||
|
|
||||||
### How to Use Ulauncher in Linux?
|
|
||||||
|
|
||||||
By default, you need to press **Ctrl + Space** to get the application launcher after you open it from the application menu for the first time.
|
|
||||||
|
|
||||||
Start typing in to search for an application. And, if you are looking for a file or directory, start typing with “**~**” or “**/**” (ignoring the quotes).
|
|
||||||
|
|
||||||
![][2]
|
|
||||||
|
|
||||||
There are default shortcuts like “**g XYZ**” where XYZ is the search term you want to search for in Google.
|
|
||||||
|
|
||||||
![][3]
|
|
||||||
|
|
||||||
Similarly, you can search for something directly taking you to Wikipedia or Stack Overflow, with “**wiki**” and “**so**” shortcuts, respectively.
|
|
||||||
|
|
||||||
Without any extensions, you can also calculate things on the go and copy the results directly to the keyboard.
|
|
||||||
|
|
||||||
![][4]
|
|
||||||
|
|
||||||
This should come in handy for quick calculations without needing to launch the calculator app separately.
|
|
||||||
|
|
||||||
You can head to its [extensions page][5] and browse for useful extensions along with screenshots that should instruct you how to use it.
|
|
||||||
|
|
||||||
To change how it works, enable frequent applications display, and adjust the theme — click on the gear icon on the right side of the launcher.
|
|
||||||
|
|
||||||
![][6]
|
|
||||||
|
|
||||||
You can set it to auto-start. But, if it does not work on your Systemd enabled distro, you can refer to its GitHub page to add it to the service manager.
|
|
||||||
|
|
||||||
The options are self-explanatory and are easy to customize, as shown in the screenshot below.
|
|
||||||
|
|
||||||
![][7]
|
|
||||||
|
|
||||||
### Installing Ulauncher in Linux
|
|
||||||
|
|
||||||
Ulauncher provides a **.deb** package for Debian or Ubuntu-based distributions. You can explore [how to install Deb][8] [f][8][iles][8] if you’re new to Linux.
|
|
||||||
|
|
||||||
In either case, you can also add its PPA and install it via terminal by following the commands below:
|
|
||||||
|
|
||||||
```
|
|
||||||
sudo add-apt-repository ppa:agornostal/ulauncher
|
|
||||||
sudo apt update
|
|
||||||
sudo apt install ulauncher
|
|
||||||
```
|
|
||||||
|
|
||||||
You can also find it available in the [AUR][9] for Arch and Fedora’s default repositories.
|
|
||||||
|
|
||||||
For more information, you can head to its official website or the [GitHub page][10].
|
|
||||||
|
|
||||||
[Ulauncher][11]
|
|
||||||
|
|
||||||
Ulauncher should be an impressive addition to any Linux distro. Especially, if you want the functionality of a quick launcher like Pop!_OS offers, this is a fantastic option to consider.
|
|
||||||
|
|
||||||
_Have you tried Ulauncher yet? You are welcome to share your thoughts on how this might help you get things done quickly._

Ulauncher:一个超级实用的 Linux 应用启动器
|
||||||
|
======
|
||||||
|
|
||||||
|
_**简介:**_ _Ulauncher 是一个快速的应用启动器,支持扩展和快捷方式,帮助你在 Linux 中快速访问应用和文件。_
|
||||||
|
|
||||||
|
一个应用启动器可以让你快速访问或打开一个应用,而无需在应用菜单图标上徘徊。
|
||||||
|
|
||||||
|
在默认情况下,我发现 Pop!_OS 的应用启动器超级方便。但是,并不是每个 Linux 发行版都提供开箱即用的应用启动器。
|
||||||
|
|
||||||
|
幸运的是,有一个你可以在大多数流行的发行版中添加应用启动器的方案。
|
||||||
|
|
||||||
|
### Ulauncher:开源应用启动器
|
||||||
|
|
||||||
|
![][1]
|
||||||
|
|
||||||
|
Ulauncher 是一个使用 Python 还有 GTK+ 构建的快速应用启动器。
|
||||||
|
|
||||||
|
它提供了相当数量的自定义和控制选项来进行调整。总的来说,你可以调整它的行为和体验以适应你的喜好。
|
||||||
|
|
||||||
|
让我来说一下你可以期待它的一些功能。
|
||||||
|
|
||||||
|
### Ulauncher 功能
|
||||||
|
|
||||||
|
Ulauncher 中的选项非常非常易于访问且易于定制。一些关键的亮点包括:
|
||||||
|
|
||||||
|
* 模糊搜索算法,让你找到应用,即使你拼错了它们
|
||||||
|
* 记住你在同一会话中最后搜索的应用
|
||||||
|
* 经常使用的应用显示(可选)
|
||||||
|
* 自定义颜色主题
|
||||||
|
* 预设颜色主题,包括一个黑暗主题
|
||||||
|
* 召唤启动器的快捷方式可以轻松定制
|
||||||
|
* 浏览文件和目录
|
||||||
|
* 支持扩展,以获得额外的功能(表情符号、天气、速度测试、笔记、密码管理器等)
|
||||||
|
* 浏览谷歌、维基百科和 Stack Overflow 等网站的快捷方式
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
|
它几乎提供了你在一个应用启动器中所期望的所有有用的能力,甚至更好。
|
||||||
|
|
||||||
|
### 如何在 Linux 中使用 Ulauncher?
|
||||||
|
|
||||||
|
默认情况下,首次从应用菜单打开应用启动器后,你需要按 **Ctrl + Space** 打开应用启动器。
|
||||||
|
|
||||||
|
开始输入以搜索一个应用。而且,如果你正在寻找一个文件或目录,开始输入 “**~**” 或者 “**/**” (忽略引号)。
|
||||||
|
|
||||||
|
![][2]
|
||||||
|
|
||||||
|
有一些默认的快捷键,如 “**g XYZ**”,其中 XYZ 是你想在谷歌中搜索的搜索词。
|
||||||
|
|
||||||
|
![][3]
|
||||||
|
|
||||||
|
同样,你可以通过 “**wiki**” 和 “**so**” 快捷键,直接在维基百科或 Stack Overflow 搜索。
|
||||||
|
|
||||||
|
在没有任何扩展的情况下,你也可以直接计算内容,并将结果直接复制到键盘上。
|
||||||
|
|
||||||
|
![][4]
|
||||||
|
|
||||||
|
这在快速计算时应该很方便,不需要单独启动计算器应用。
|
||||||
|
|
||||||
|
你可以前往它的[扩展页面][5],浏览有用的扩展,以及指导你如何使用它的截图。
|
||||||
|
|
||||||
|
要改变它的工作方式,启用频繁的应用显示,并调整主题,请点击启动器右侧的齿轮图标。
|
||||||
|
|
||||||
|
![][6]
|
||||||
|
|
||||||
|
你可以把它设置为自动启动。但是,如果它在你的支持 Systemd 的发行版上不工作,你可以参考它的 GitHub 页面,把它添加到服务管理器中。
|
||||||
|
|
||||||
|
这些选项是非常只管,且易于定制,如下图所示。
|
||||||
|
|
||||||
|
![][7]
|
||||||
|
|
||||||
|
### 在 Linux 中安装 Ulauncher
|
||||||
|
|
||||||
|
Ulauncher 为基于 Debian 或 Ubuntu 的发行版提供了一个 **.deb** 包。如果你是 Linux 新手,你可以探索[如何安装 Deb 文件][8] 。
|
||||||
|
|
||||||
|
在这两种情况下,你也可以添加它的 PPA,并通过终端按照下面的命令来安装它:
|
||||||
|
|
||||||
|
```
|
||||||
|
sudo add-apt-repository ppa:agornostal/ulauncher
|
||||||
|
sudo apt update
|
||||||
|
sudo apt install ulauncher
|
||||||
|
```
|
||||||
|
|
||||||
|
你也可以在 [AUR][9] 中找到它,用于 Arch 和 Fedora 的默认仓库。
