Oh My Fish! Make Your Shell Beautiful
|
||||
======
|
||||
|
||||
|
||||
A few days ago, we discussed how to [**install** **Fish shell**][1], a robust, fully-usable shell that ships with many cool features out of the box such as autosuggestions, built-in search functionality, syntax highlighting, web based configuration and a lot more. Today, we are going to discuss how to make our Fish shell beautiful and elegant using **Oh My Fish** (shortly **omf** ). It is a Fishshell framework that allows you to install packages which extend or modify the look and feel of your shell. It is easy to use, fast and extensible. Using omf, you can easily install themes that enriches the look of your shell and install plugins to tweak your fish shell as per your wish.
|
||||
|
||||
#### Install Oh My Fish
|
||||
|
||||
Installing omf is not a big deal. All you have to do is just run the following command in your fish shell.
|
||||
```
|
||||
curl -L https://get.oh-my.fish | fish
|
||||
```
|
||||
|
||||
![][3]
|
||||
|
||||
Once the installation has completed, you will see the the prompt has automatically changed as shown in the above picture. Also, you will notice that the current time on the right of the shell window.
|
||||
|
||||
That's it. Let us go ahead and tweak our fish shell.
|
||||
|
||||
#### Now, Let Us Make Our Fish Shell Beautiful
|
||||
|
||||
To list all installed packages, run:
|
||||
```
|
||||
omf list
|
||||
```
|
||||
|
||||
This command will display both the installed themes and plugins. Please note that a package can be either a theme or plugin. Installing packages means installing themes or plugins.
|
||||
|
||||
All official and community supported packages (both plugins and themes) are hosted in the [**main Omf repository**][4]. In this repository, you can see a whole bunch of repositories that contains a lot of plugins and themes.
|
||||
|
||||
Now let us see the list of available and installed themes. To do so, run:
|
||||
```
|
||||
omf theme
|
||||
```
|
||||
|
||||
[![][2]][5]
|
||||
|
||||
As you can see, we have only one installed theme, which is default, and a whole bunch of available themes. You can preview all available themes [**here**][6] before installing it. This page contains all theme details, features, a sample screenshot of each theme and which theme is suitable for whom.
|
||||
|
||||
**Installing a new theme**
|
||||
|
||||
Allow me to install a theme, for example **clearance theme - **a minimalist fish shell theme for people who use git a lot. To do so, run:
|
||||
```
|
||||
omf install clearance
|
||||
```
|
||||
|
||||
[![][2]][7]
|
||||
|
||||
As you see in the above picture, the look of fish prompt has changed immediately after installing the new theme.
|
||||
|
||||
Let me browse through the file system and see how it looks like.
|
||||
|
||||
[![][2]][8]
|
||||
|
||||
Not bad! It is really simple theme. It distinguishes the current working directory, folders and files with different color. As you may notice, it also displays the current working directory on top of the prompt. Currently, **clearance** is my default theme.
|
||||
|
||||
**Changing theme**
|
||||
|
||||
Like I already said, the theme will be applied immediately after installing it. If you have more than one themes, you can switch to a different theme using the following command:
|
||||
```
|
||||
omf theme <theme-name>
|
||||
```
|
||||
|
||||
Example:
|
||||
```
|
||||
omf theme agnoster
|
||||
```
|
||||
|
||||
Now I am using "agnoster" theme. Here is how agnoster theme changed the look of my shell.
|
||||
|
||||
[![][2]][9]
|
||||
|
||||
**Installing Plugins**
|
||||
|
||||
For instance, I am going to install weather plugin. To do so, just run:
|
||||
```
|
||||
omf install weather
|
||||
```
|
||||
|
||||
The weather plugin depends on [jq][10]. So, you might need to install jq as well. It is mostly available in the default repositories of any Linux distro. So, you can install it using the default package manager. For example, the following command will install jq in Arch Linux and its variants.
|
||||
```
|
||||
sudo pacman -S jq
|
||||
```
|
||||
|
||||
Now, check your weather from your fish shell using command:
|
||||
```
|
||||
weather
|
||||
```
|
||||
|
||||
[![][2]][11]
|
||||
|
||||
**Searching packages**
|
||||
|
||||
To search for a theme or plugin, do:
|
||||
```
|
||||
omf search <search_string>
|
||||
```
|
||||
|
||||
Example:
|
||||
```
|
||||
omf search nvm
|
||||
```
|
||||
|
||||
To limit the search to themes, use **-t** flag.
|
||||
```
|
||||
omf search -t chain
|
||||
```
|
||||
|
||||
This command will only search for themes that contains the string "chain".
|
||||
|
||||
To limit the search to plugins, use **-p** flag.
|
||||
```
|
||||
omf search -p emacs
|
||||
```
|
||||
|
||||
**Updating packages**
|
||||
|
||||
To update only the core (omf itself), run:
|
||||
```
|
||||
omf update omf
|
||||
```
|
||||
|
||||
If it is up-to-date, you would see the following output:
|
||||
```
|
||||
Oh My Fish is up to date.
|
||||
You are now using Oh My Fish version 6.
|
||||
Updating https://github.com/oh-my-fish/packages-main master... Done!
|
||||
```
|
||||
|
||||
To update all packages:
|
||||
```
|
||||
omf update
|
||||
```
|
||||
|
||||
To selectively update packages, just include the packages names as shown below.
|
||||
```
|
||||
omf update clearance agnoster
|
||||
```
|
||||
|
||||
**Displaying information about a package**
|
||||
|
||||
When you want to know the information about a theme or plugin, use this command:
|
||||
```
|
||||
omf describe clearance
|
||||
```
|
||||
|
||||
This command will show the information about a package.
|
||||
```
|
||||
Package: clearance
|
||||
Description: A minimalist fish shell theme for people who use git
|
||||
Repository: https://github.com/oh-my-fish/theme-clearance
|
||||
Maintainer:
|
||||
```
|
||||
|
||||
**Removing packages**
|
||||
|
||||
To remove a package, for example emacs, run:
|
||||
```
|
||||
omf remove emacs
|
||||
```
|
||||
|
||||
**Managing Repositories**
|
||||
|
||||
By default, the official repository is added automatically when you install Oh My Fish. This repository contains all packages built by the developers. To manage user-installed package repositories, use this command:
|
||||
```
|
||||
omf repositories [list|add|remove]
|
||||
```
|
||||
|
||||
To list installed repositories, run:
|
||||
```
|
||||
omf repositories list
|
||||
```
|
||||
|
||||
To add a repository:
|
||||
```
|
||||
omf repositories add <URL>
|
||||
```
|
||||
|
||||
Example:
|
||||
```
|
||||
omf repositories add https://github.com/ostechnix/theme-sk
|
||||
```
|
||||
|
||||
To remove a repository:
|
||||
```
|
||||
omf repositories remove <repository-name>
|
||||
```
|
||||
|
||||
**Troubleshooting Oh My Fish**
|
||||
|
||||
Omf is smart enough to help you if things went wrong. It will list what to do to fix an issue. For example, I removed and installed clearance package and got file conflicting error. Luckily, Oh My Fish instructed me what to do before continuing. So, I simply ran the following to know how to fix the error:
|
||||
```
|
||||
omf doctor
|
||||
```
|
||||
|
||||
And fixed the issued the error by running the following command:
|
||||
```
|
||||
rm ~/.config/fish/functions/fish_prompt.fish
|
||||
```
|
||||
|
||||
[![][2]][12]
|
||||
|
||||
Whenever you ran into a problem, just run 'omf doctor' command and try all suggested workarounds.
|
||||
|
||||
**Getting help**
|
||||
|
||||
To display help section, run:
|
||||
```
|
||||
omf -h
|
||||
```
|
||||
|
||||
Or,
|
||||
```
|
||||
omf --help
|
||||
```
|
||||
|
||||
**Uninstalling Oh My Fish**
|
||||
|
||||
To uninstall Oh My Fish, run this command:
|
||||
```
|
||||
omf destroy
|
||||
```
|
||||
|
||||
Go ahead and start customizing your fish shell. For more details, refer the project's GitHub page.
|
||||
|
||||
That's all for now folks. I will be soon here with another interesting guide. Until then, stay tuned with OSTechNix!
|
||||
|
||||
Cheers!

Oh My Fish! 让你的 Shell 漂亮起来
|
||||
=====
|
||||
|
||||
|
||||
|
||||
几天前，我们讨论了如何 [**安装** **Fish shell**][1]，一个健壮的，完全可用的 shell，带有许多很酷的功能，如自动建议，内置搜索功能，语法高亮显示，基于 web 配置等等。今天，我们将讨论如何使用 **Oh My Fish** (简称 **omf** ) 让我们的 Fish shell 变得漂亮且优雅。它是一个 Fishshell 框架，允许你安装扩展或更改 shell 外观的软件包。它简单易用，快速可扩展。使用 omf，你可以根据你的想法，很容易地安装主题，丰富你的外观和安装插件来调整你的 fish shell。
|
||||
|
||||
#### 安装 Oh My Fish
|
||||
|
||||
安装 omf 很简单。你要做的只是在你的 fish shell 中运行下面的命令。
|
||||
```
|
||||
curl -L https://get.oh-my.fish | fish
|
||||
```
|
||||
|
||||
![][3]
|
||||
|
||||
一旦安装完成，你将看到提示已经自动更改，如上图所所示。另外，你会注意到当前时间在 shell 窗口的右边。
|
||||
|
||||
就是这样。让我们继续并调整我们的 fish shell。
|
||||
|
||||
#### 现在，让我们将 Fish Shell 变漂亮
|
||||
|
||||
列出所有的安装包，运行：
|
||||
```
|
||||
omf list
|
||||
```
|
||||
|
||||
这条命令将显示已安装的主题和插件。请注意，包可以是主题或插件。安装包意味着安装主题和插件。
|
||||
|
||||
所有官方和社区支持的包（包括插件和主题）都托管在 [**Omf 主仓库**][4] 中。在这个主仓库中，你可以看到大量的仓库，其中包含大量的插件和主题。
|
||||
|
||||
现在让我们看一下可用的和已安装的主题列表。为此，运行：
|
||||
```
|
||||
omf theme
|
||||
```
|
||||
|
||||
![][5]
|
||||
|
||||
如你所见，我们只有一个已安装的主题，这是默认的，但是还有大量可用的主题。在安装之前，你在[**这里**][6]可以预览所有可用的主题。这个页面包含了所有的主题细节，特性，每个主题的截图示例，以及哪个主题适合谁。
|
||||
|
||||
**安装一个新主题**
|
||||
|
||||
请允许我安装一个主题，例如 **clearance theme - **一个极简的 fish shell 主题，供那些经常使用 git 的人使用。为此，运行：
|
||||
```
|
||||
omf install clearance
|
||||
```
|
||||
|
||||
![][7]
|
||||
|
||||
如上图所示，在安装新主题后，fish 的提示立即发生了变化。
|
||||
|
||||
让我浏览一下系统文件，看看它如何显示。
|
||||
|
||||
![][8]
|
||||
|
||||
看起来不坏！这是一个非常简单的主题。它将当前工作目录，文件夹和文件以不同的颜色区分开来。你可能会注意到，它还会在提示符的顶部显示当前工作目录。现在，**clearance** 是我的默认主题。
|
||||
|
||||
**改变主题**
|
||||
|
||||
就像我之前说的一样，这个主题在安装后被立即应用。如果你有多个主题，你可以使用以下命令切换到另一个不同的主题：
|
||||
```
|
||||
omf theme <theme-name>
|
||||
```
|
||||
|
||||
例如：
|
||||
```
|
||||
omf theme agnoster
|
||||
```
|
||||
|
||||
现在我正在使用 "agnoster" 主题。 agnoster 就是这样改变了我 shell 的外观。
|
||||
|
||||
![][9]
|
||||
|
||||
**安装插件**
|
||||
|
||||
例如，我想安装一个天气插件。为此，，只要运行：
|
||||
```
|
||||
omf install weather
|
||||
```
|
||||
|
||||
天气插件依赖于 [jq][10]（LCTT 译注：jq 是一个轻量级且灵活的命令行JSON处理器）。所以，你可能也需要安装 jq。它通常在 Linux 发行版的默认仓库中存在。因此，你可以使用默认的包管理器来安装它。例如，以下命令将在 Arch Linux 及其衍生版中安装 jq。
|
||||
```
|
||||
sudo pacman -S jq
|
||||
```
|
||||
|
||||
现在，在 fish shell 中使用以下命令查看天气：
|
||||
```
|
||||
weather
|
||||
```
|
||||
|
||||
![][11]
|
||||
|
||||
**寻找包**
|
||||
|
||||
要搜索主题或插件，请执行以下操作：
|
||||
```
|
||||
omf search <search_string>
|
||||
```
|
||||
|
||||
例如：
|
||||
```
|
||||
omf search nvm
|
||||
```
|
||||
|
||||
为了限制搜索的主题范围，使用 **-t** 选项。
|
||||
```
|
||||
omf search -t chain
|
||||
```
|
||||
|
||||
这条命令只会搜索主题名字中包含 "chain" 的主题。
|
||||
|
||||
为了限制搜索的插件范围，使用 **-p** 选项。
|
||||
```
|
||||
omf search -p emacs
|
||||
```
|
||||
|
||||
**更新包**
|
||||
|
||||
要仅更新核心功能（omf 本身），运行：
|
||||
```
|
||||
omf update omf
|
||||
```
|
||||
|
||||
如果是最新的，你会看到以下输出：
|
||||
```
|
||||
Oh My Fish is up to date.
|
||||
You are now using Oh My Fish version 6.
|
||||
Updating https://github.com/oh-my-fish/packages-main master... Done!
|
||||
```
|
||||
|
||||
更新所有包：
|
||||
```
|
||||
omf update
|
||||
```
|
||||
|
||||
要有选择地更新软件包，只需包含如下所示的包名称：
|
||||
```
|
||||
omf update clearance agnoster
|
||||
```
|
||||
|
||||
**显示关于包的信息**
|
||||
|
||||
当你想知道关于一个主题或插件的信息时，使用以下命令：
|
||||
```
|
||||
omf describe clearance
|
||||
```
|
||||
|
||||
这条命令将显示关于包的信息。
|
||||
```
|
||||
Package: clearance
|
||||
Description: A minimalist fish shell theme for people who use git
|
||||
Repository: https://github.com/oh-my-fish/theme-clearance
|
||||
Maintainer:
|
||||
```
|
||||
|
||||
**移除包**
|
||||
|
||||
移除一个包，例如 emacs，运行：
|
||||
```
|
||||
omf remove emacs
|
||||
```
|
||||
|
||||
**管理仓库**
|
||||
|
||||
默认情况下，当你安装了 Oh My Fish 时，会自动添加官方仓库。这个仓库包含了开发人员构建的所有包。要管理用户安装的仓库包，使用这条命令：
|
||||
```
|
||||
omf repositories [list|add|remove]
|
||||
```
|
||||
|
||||
列出所有安装的仓库，运行：
|
||||
```
|
||||
omf repositories list
|
||||
```
|
||||
|
||||
添加一个仓库：
|
||||
```
|
||||
omf repositories add <URL>
|
||||
```
|
||||
|
||||
例如：
|
||||
```
|
||||
omf repositories add https://github.com/ostechnix/theme-sk
|
||||
```
|
||||
|
||||
移除一个仓库：
|
||||
```
|
||||
omf repositories remove <repository-name>
|
||||
```
|
||||
|
||||
**Troubleshooting Oh My Fish**
|
||||
|
||||
如果出现了错误，omf 足够聪明来帮助你，它可以列出解决问题的方法。例如，我删除并安装了 clearance 包（这句不太理解，希望校正者注意），得到了文件冲突的错误。幸运的是，在继续之前，Oh My Fish 会指示我该怎么做。因此，我只是简单地运行了以下代码来了解如何修正错误。
|
||||
```
|
||||
omf doctor
|
||||
```
|
||||
|
||||
通过运行以下命令来解决错误：
|
||||
```
|
||||
rm ~/.config/fish/functions/fish_prompt.fish
|
||||
```
|
||||
|
||||
![][12]
|
||||
|
||||
无论你何时遇到问题，只要运行 'omf doctor' 命令，并尝试所有的建议方法。
|
||||
|
||||
**获取帮助**
|
||||
|
||||
显示帮助部分，运行：
|
||||
```
|
||||
omf -h
|
||||
```
|
||||
|
||||
或者
|
||||
```
|
||||
omf --help
|
||||
```
|
||||
|
||||
**卸载 Oh My Fish**
|
||||
|
||||
卸载 Oh My Fish，运行以下命令：
|
||||
```
|
||||
omf destroy
|
||||
```
|
||||
|
||||
继续前进，开始自定义你的 fish shell。获取更多细节，请参考项目的 GitHub 页面。
|
||||
|
||||
这就是全部了。我很快将会在这里开始另一个有趣的指导。在此之前，请继续关注 OSTechNix!
|
||||
|
