In this article, I will show you how to install Powerline and Powerline fonts and how to use with Bash and Vimunder RedHat and Debian based systems.
|
||||
在本文中，我会介绍如何安装Powerline和相应字体，以及如何在RedHat和Debian类的系统中使用Bash和Vim支持Powerline。
|
||||
|
||||
### Step 1: Installing Generic Requirements for Powerline
|
||||
### 第一步：准备好安装Powerline需要的软件
|
||||
|
||||
Due to a naming conflict with some other unrelated projects, powerline program is available on PyPI (Python Package Index) under the package name as powerline-status.
|
||||
由于和其他不相干项目之间存在命名冲突，因此powerline只能放在PyPI(Python Package Index)中的powerline-status包下.
|
||||
|
||||
To install packages from PyPI, we need a ‘pip‘ (package management tool for installing Python packages). So, let’s first install pip tool under our Linux systems.
|
||||
为了从PyPI中安装该包，需要先准备好pip(该工具专门用于Python包的管理)工具。所以首先要在Linux系统下安装好pip工具。
|
||||
|
||||
#### Install Pip on Debian, Ubuntu and Linux Mint
|
||||
#### 在Debian,Ubuntu和Linux Mint中安装Pip的方法
|
||||
|
||||
```
|
||||
# apt-get install python-pip
|
||||
```

|

#### 在CentOS，RHEL和Fedora中安装Pip

||||
Under Fedora-based systems, you need to first [enable epel-repository][4] and then install pip package as shown.
|
||||
在Fedora类系统中，需要先打开[epel-repository][4]然后按照如下方法安装pip包。
|
||||
|
||||
```
|
||||
# yum install python-pip
|
||||
# dnf install python-pip [On Fedora 22+ versions]

### 第二步：在Linux中安装Powerline
|
||||
|
||||
Now it’s’ time to install Powerline latest development version from the Git repository. For this, your system must have git package installed in order to fetch the packages from Git.
|
||||
现在可以从Git仓库中安装Powerline的最新开发版。在此之前系统需要安装好Git工具以便可以从仓库拉下代码。

|

### 第三步：在Linux中安装Powerline的字体
|
||||
|
||||
### Step 3: Installing Powerline Fonts in Linux
|
||||
Powerline使用特殊的符号来为开发者显示特殊的箭头效果和符号内容。因此你的系统中必须要有符号字体或者补丁字体。
|
||||
|
||||
Powerline uses special glyphs to show special arrow effect and symbols for developers. For this, you must have a symbol font or a patched font installed on your systems.
|
||||
|
||||
Download the most recent version of the symbol font and fontconfig configuration file using following [wget command][5].
|
||||
通过下面的[wget][5]命令下载最新的系统字体及字体配置文件。
|
||||
|
||||
```
|
||||
# wget https://github.com/powerline/powerline/raw/develop/font/PowerlineSymbols.otf
|
||||
# wget https://github.com/powerline/powerline/raw/develop/font/10-powerline-symbols.conf
|
||||
```
|
||||
|
||||
Then you need to move the font to your fonts directory, /usr/share/fonts/ or /usr/local/share/fonts as follows or you can get the valid font paths by using command `xset q`.
|
||||
然后你将下载的字体放到字体目录下/usr/share/fonts或者/usr/local/share/fonts，或者你可以通过'xset q'命令找到一个有效的字体目录。
|
||||
|
||||
```
|
||||
# mv PowerlineSymbols.otf /usr/share/fonts/
|
||||
```
|
||||
|
||||
Next, you need to update your system’s font cache as follows.
|
||||
接下来你需要通过如下命令更新你系统的字体缓存。
|
||||
|
||||
```
|
||||
# fc-cache -vf /usr/share/fonts/
|
||||
```
|
||||
|
||||
Now install the fontconfig file.
|
||||
其次安装字体配置文件。
|
||||
|
||||
```
|
||||
# mv 10-powerline-symbols.conf /etc/fonts/conf.d/
|
||||
```
|
||||
注意：如果相应的符号没有出现，可以尝试关闭终端会话并重启X window，这样就会生效了。
|
||||
|
||||
Note: If custom symbols doesn’t appear, then try to close all terminal sessions and restart X window for the changes to take effect.
|
||||
### 步骤4：给Bash Shell和Vim状态行设置Powerline
|
||||
|
||||
### Step 4: Setting Powerline for Bash Shell and Vim Statuslines
|
||||
|
||||
In this section we shall look at configuring Powerline for bash shell and vim editor. First make your terminal to support 256color by adding the following line to ~/.bashrc file as follows.
|
||||
在这一节将介绍bash shell和vim editor中关于Powerline的配置。首先通过在~/.bashrc中添加如下内容以便设置终端为256色。
|
||||
|
||||
```
|
||||
export TERM=”screen-256color”
|
||||
```
|
||||
|
||||
#### Enable Powerline on Bash Shell
|
||||
#### 打开Bash Shell中的Powerline
|
||||
|
||||
To enable Powerline in bash shell by default, you need to add the following snippet to your ~/.bashrc file.
|
||||
如果希望在bash shell中默认打开Powerline，可以在~/.bashrc中添加如下内容。
|
||||
|
||||
First get the location of installed powerline using following command.
|
||||
首先通过如下命令获取powerline的安装位置。

#### Enable Powerline for Vim
|
||||
#### 在Vim中打开Powerline
