Powerline：Vim 和 Bash 中的一个强大状态栏插件

Powerline 是 vim、zsh、bash、tmux、IPython、Awesome、bar、fish、lemonbar、pdb、rc、shell、tcsh、wm、i3 和 Qtil 中的一个状态栏插件。它给程序提供了状态栏，并使程序更好看。它用 Python 写成。

它是可扩展的并且功能丰富，它用 Python 写成，非常轻便不需要任何第三方的依赖，只需要一个 Python 解释器。

它的稳定以及可测试的代码库经过完整的测试，并且在 Python 2.6+ 和 Python 3 中工作良好。

最初该状态栏只在 vim 中可用，随后项目进化为许多 Linux 程序如 zsh、bash、tmux、IPython、Awesome、i3 和 Qtil 提供状态栏。

其配置以及配色方案用 JSON 写成。它是一种标准简易的文件格式，可以让用户配置 Powerline 支持的程序。

快速并且轻量级，支持守护进程可以提供更好的性能。

如何在 Linux 中安装 Powerline

在本篇中，我们将向你展示如何安装 Powerline。以及如何在基于 Debian 以及 RHEL 的系统中在 Bash、tumx 和 Vim 中使用。

1. <span class="pln">$ </span><span class="kwd">sudo</span><span class="pln"> pip install </span><span class="kwd">git</span><span class="pun">+</span><span class="kwd">git</span><span class="pun">:</span><span class="com">//github.com/Lokaltog/powerline</span>

找出 powerline 安装位置以便配置程序。

1. <span class="pln">$ pip show powerline</span><span class="pun">-</span><span class="pln">status</span>

在 Bash Shell 中添加/启用 Powerline

添加下面的行到 .bashrc 中，它会默认在基础 shell 中启用 powerline。

1. <span class="kwd">if</span><span class="pun">[</span><span class="pun">-</span><span class="pln">f </span><span class="str">`which powerline-daemon`</span><span class="pun">];</span><span class="kwd">then</span>
2. <span class="pln">powerline</span><span class="pun">-</span><span class="pln">daemon </span><span class="pun">-</span><span class="pln">q</span>
3. <span class="pln">POWERLINE_BASH_CONTINUATION</span><span class="pun">=</span><span class="lit">1</span>
4. <span class="pln">POWERLINE_BASH_SELECT</span><span class="pun">=</span><span class="lit">1</span>
5. <span class="pun">.</span><span class="pun">/</span><span class="pln">usr</span><span class="pun">/</span><span class="kwd">local</span><span class="pun">/</span><span class="pln">lib</span><span class="pun">/</span><span class="pln">python2</span><span class="pun">.</span><span class="lit">7</span><span class="pun">/</span><span class="pln">site</span><span class="pun">-</span><span class="pln">packages</span><span class="pun">/</span><span class="pln">powerline</span><span class="pun">/</span><span class="pln">bindings</span><span class="pun">/</span><span class="kwd">bash</span><span class="pun">/</span><span class="pln">powerline</span><span class="pun">.</span><span class="pln">sh</span>
6. <span class="kwd">fi</span>

重新加载 .bashrc 文件使得 powerline 在当前窗口中立即生效。

1. <span class="pln">$ source </span><span class="pun">~/.</span><span class="pln">bashrc</span>

在 tmux 中添加/启用 Powerline

tmux 是最好的终端仿真程序之一，它提供多窗口以及状态栏，但是相比 powerline 的状态栏看上去不那么好。添加下面的的行到 .tmux.conf 中，它会默认在 tmux 中启用 powerline。如果你没有找到 .tmux.conf 文件，那么创建一个新的。

1. <span class="com">#</span><span class="kwd">vi</span><span class="pun">~/.</span><span class="pln">tmuc</span><span class="pun">.</span><span class="pln">conf</span>
2. <span class="pln">source </span><span class="str">"/usr/local/lib/python2.7/site-packages/powerline/bindings/tmux/powerline.conf"</span>

在 Vim 中添加/启用 Powerline

vim 是管理员最爱的文本编辑器之一。添加下面的行到 .vimrc 中，启用 powerline 使 vim 更加强大。注意，在 vim 7.x 中，你可能不会在系统中发现 .vimrc 文件，因此不必担心，创建一个新的文件，并添加下面行。

1. <span class="com">#</span><span class="kwd">vi</span><span class="pun">~/.</span><span class="pln">vimrc</span>
2. <span class="kwd">set</span><span class="pln"> rtp</span><span class="pun">+=</span><span class="str">/usr/</span><span class="kwd">local</span><span class="pun">/</span><span class="pln">lib</span><span class="pun">/</span><span class="pln">python2</span><span class="pun">.</span><span class="lit">7</span><span class="pun">/</span><span class="pln">site</span><span class="pun">-</span><span class="pln">packages</span><span class="pun">/</span><span class="pln">powerline</span><span class="pun">/</span><span class="pln">bindings</span><span class="pun">/</span><span class="kwd">vim</span><span class="pun">/</span>
3. <span class="kwd">set</span><span class="pln"> laststatus</span><span class="pun">=</span><span class="lit">2</span>
4. <span class="kwd">set</span><span class="pln"> t_Co</span><span class="pun">=</span><span class="lit">256</span>
