How to Install Cockpit in Fedora / CentOS / RHEL/ Arch Linux
|
||||
================================================================================
|
||||
Cockpit is a free and open source server management software that makes us easy to administer our GNU/Linux servers via its beautiful web interface frontend. Cockpit helps make linux system administrator, system maintainers and DevOps easy to manage their server and to perform simple tasks, such as administering storage, inspecting journals, starting and stopping services and more. Its journal interface adds aroma in flower making people easy to switch between the terminal and web interface. And moreover, it makes easy to manage not only one server but several multiple networked servers from a single place at the same time with just a single click. It is very light weight and has easy to use web based interface. In this tutorial, we'll learn how we can setup Cockpit and use it to manage our server running Fedora, CentOS, Arch Linux and RHEL distributions as their operating system software. Some of the awesome benefits of Cockpit in our GNU/Linux servers are as follows:
|
||||
|
||||
1. It consist of systemd service manager for ease.
|
||||
1. It has a Journal log viewer to perform troubleshoots and log analysis.
|
||||
1. Storage setup including LVM was never easier before.
|
||||
1. Basic Network configuration can be applied with Cockpit
|
||||
1. We can easily add and remove local users and manage multiple servers.
|
||||
|
||||
### 1. Installing Cockpit ###
|
||||
|
||||
First of all, we'll need to setup Cockpit in our linux based server. In most of the distributions, the cockpit package is already available in their official repositories. Here, in this tutorial, we'll setup Cockpit in Fedora 22, CentOS 7, Arch Linux and RHEL 7 from their official repositories.
|
||||
|
||||
#### On CentOS / RHEL ####
|
||||
|
||||
Cockpit is available in the official repository of CenOS and RHEL. So, we'll simply install it using yum manager. To do so, we'll simply run the following command under sudo/root access.
|
||||
|
||||
# yum install cockpit
|
||||
|
||||
|
||||
|
||||
#### On Fedora 22/21 ####
|
||||
|
||||
Alike, CentOS, it is also available by default in Fedora's official repository, we'll simply install cockpit using dnf package manager.
|
||||
|
||||
# dnf install cockpit
|
||||
|
||||
|
||||
|
||||
#### On Arch Linux ####
|
||||
|
||||
Cockpit is currently not available in the official repository of Arch Linux but it is available in the Arch User Repository also know as AUR. So, we'll simply run the following yaourt command to install it.
|
||||
|
||||
# yaourt cockpit
|
||||
|
||||
|
||||
|
||||
### 2. Starting and Enabling Cockpit ###
|
||||
|
||||
After we have successfully installed it, we'll gonna start the cockpit server with our service/daemon manager. As of 2015, most of the linux distributions have adopted Systemd whereas some of the linux distributions still run SysVinit to manage daemon, but Cockpit uses systemd for almost everything from running daemons to services. So, we can only setup Cockpit in the latest releases of linux distributions running Systemd. In order to start Cockpit and make it start in every boot of the system, we'll need to run the following command in a terminal or a console.
|
||||
|
||||
# systemctl start cockpit
|
||||
|
||||
# systemctl enable cockpit.socket
|
||||
|
||||
Created symlink from /etc/systemd/system/sockets.target.wants/cockpit.socket to /usr/lib/systemd/system/cockpit.socket.
|
||||
|
||||
### 3. Allowing Firewall ###
|
||||
|
||||
After we have started our cockpit server and enable it to start in every boot, we'll now go for configuring firewall. As we have firewall programs running in our server, we'll need to allow ports in order to make cockpit accessible outside of the server.
|
||||
|
||||
#### On Firewalld ####
|
||||
|
||||
# firewall-cmd --add-service=cockpit --permanent
|
||||
|
||||
success
|
||||
|
||||
# firewall-cmd --reload
|
||||
|
||||
success
|
||||
|
||||
|
||||
|
||||
#### On Iptables ####
|
||||
|
||||
# iptables -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
|
||||
|
||||
# service iptables save
|
||||
|
||||
### 4. Accessing Cockpit Web Interface ###
|
||||
|
||||
Next, we'll gonna finally access the Cockpit web interface using a web browser. We'll simply need to point our web browser to https://ip-address:9090 or https://server.domain.com:9090 according to the configuration. Here, in our tutorial, we'll gonna point our browser to https://128.199.114.17:9090 as shown in the image below.
|
||||
|
||||
|
||||
|
||||
We'll be displayed an SSL certification warning as we are using a self-signed SSL certificate. So, we'll simply ignore it and go forward towards the login page, in chrome/chromium, we'll need to click on Show Advanced and then we'll need to click on **Proceed to 128.199.114.17 (unsafe)** .
|
||||
|
||||
|
||||
|
||||
Now, we'll be asked to enter the login details in order to enter into the dashboard. Here, the username and password is the same as that of the login details we use to login to our linux server. After we enter the login details and click on Log In button, we will be welcomed into the Cockpit Dashboard.
|
||||
|
||||
|
||||
|
||||
Here, we'll see all the menu and visualization of CPU, Disk, Network, Storage usages of the server. We'll see the dashboard as shown above.
|
||||
|
||||
#### Services ####
|
||||
|
||||
To manage services, we'll need to click on Services button on the menu situated in the right side of the web page. Then, we'll see the services under 5 categories, Targets, System Services, Sockets, Timers and Paths.
|
||||
|
||||
|
||||
|
||||
#### Docker Containers ####
|
||||
|
||||
We can even manage docker containers with Cockpit. It is pretty easy to monitor and administer Docker containers with Cockpit. As docker isn't installed and running in our server, we'll need to click on Start Docker.
|
||||
|
||||
|
||||
|
||||
Cockpit will automatically install and run docker in our server. After its running, we see the following screen. Then, we can manage the docker images, containers as per our requirement.
|
||||
|
||||
|
||||
|
||||
#### Journal Log Viewer ####
|
||||
|
||||
Cockpit has a managed log viewer which separates the Errors, Warnings, Notices into different tabs. And we also have a tab All where we can see them all in a single place.
|
||||
|
||||
|
||||
|
||||
#### Networking ####
|
||||
|
||||
Under the networking section, we see two graphs in which there is the visualization of Sending and Receiving speed. And we can see there the list of available interfaces with option to Add Bond, Bridge, VLAN. If we need to configure an interface, we can do so by simply clicking on the interface name. Below everything, we can see the Journal Log Viewer for Networking.
|
||||
|
||||
|
||||
|
||||
#### Storage ####
|
||||
|
||||
Now, its easy with Cockpit to see the R/W speed of our hard disk. We can see the Journal log of the Storage in order to perform troubleshoot and fixes. A clear visualization bar of how much space is occupied is shown in the page. We can even Unmount, Format, Delete a partition of a Hard Disk and more. Features like creating RAID Device, Volume Group is also available in it.
|
||||
|
||||
|
||||
|
||||
#### Account Management ####
|
||||
|
||||
We can easily create new accounts with Cockpit Web Interface. The accounts created in it is applied to the system's user account. We can change password, specify roles, delete, rename user accounts with it.
|
||||
|
||||
|
||||
|
||||
#### Live Terminal ####
|
||||
|
||||
This is an awesome feature built-in with Cockpit. Yes, we can execute commands, do stuffs with the live terminal provided by Cockpit interface. This makes us really easy to switch between the web interface and terminal according to our need.
|
||||
|
||||
|
||||
|
||||
### Conclusion ###
|
||||
|
||||
Cockpit is a good free and open source software developed by [Red Hat][1] for making the server management easy and simple. It is best for performing simple system administration tasks and is good for the new system administrators. It is still under pre-release as its stable release hasn't been released yet. So, it is not suitable for production. It is currently developed on the latest release of Fedora, CentOS, Arch Linux, RHEL where systemd is installed by default. If you are willing to install Cockpit in Ubuntu, you can get the PPA access but is currently outdated. If you have any questions, suggestions, feedback please write them in the comment box below so that we can improve or update our contents. Thank You !

Linux / Unix Desktop Fun: Text Mode ASCII-art Box and Comment Drawing
|
||||
================================================================================
|
||||
Boxes command is a text filter and a little known tool that can draw any kind of ASCII art box around its input text or code for fun and profit. You can quickly create email signatures, or create regional comments in any programming language. This command was intended to be used with the vim text editor, but can be tied to any text editor which supports filters, as well as from the command line as a standalone tool.

What are the best plugins to increase productivity on Emacs
|
||||
================================================================================
|
||||
Over a year ago now, I went looking for the best plugins to [turn Vim into a full-fledged IDE][1]. Interestingly, a lot of the comments on that post were about how Emacs already has most of these plugins built in, and was already a great IDE. Although I can only agree about Emacs' incredible versatility, it is still not the ultimate editor when it comes out of the box. Thankfully, its vast plugin library is here to fix that. But among the plethora of options available to you, it is sometimes hard to know where to start. So for now, let me try to assemble a short list of the indispensable plugins to increase your productivity while using Emacs. Although I am heavily geared towards programming related productivity, most of these plugins would be useful to anyone for any usage.
|
||||
|
||||
### 1. Ido-mode ###
|
||||
|
||||
|
||||
|
||||
Maybe one of the most useful plugin for beginners, Ido stands for interactively do. It replaces most of the dry prompts with a fancy character matching menu. For example, it will replace the normal prompt to open a file with a list of all the files in the current directory. Type any string, and Ido will try to match it with the most appropriate file. It makes it really easy to visualize your actions, and also to quickly get through a folder where all files are named with the same prefix.
|
||||
|
||||
### 2. Smex ###
|
||||
|
||||
|
||||
|
||||
Not the most famous one, but a good place to complete what Ido-mode started: Smex can be a fancy replacement to the normal 'M-x' prompt, with a heavy inspiration from Ido-mode. It brings the same interactive search for the commands you would normally have to type after calling 'M-x'. It is simple and efficient, and a great way to save those additional few fractions of a second you normally need.
|
||||
|
||||
### 3. Auto Complete ###
|
||||
|
||||
|
||||
|
||||
Before knowing the existence of this plugin, I spent half of my time on Emacs pressing ‘M-/’ to complete my words. Now, I have a fancy pop-up to do it for me. There is not much more to say about it, except that we all need it.
|
||||
|
||||
### 4. YASnippet ###
|
||||
|
||||
|
||||
|
||||
This one is really for the coders. There is always some piece of code that we feel we use all the time. For me, it's 'var_dump(...); exit;' to debug PHP. After a while of typing it over and over, it just occurred to me that I could have it pre-recorded and easily accessible as a snippet of code. With YASnippets, it's easy to import snippet files or make your own. After that, a simple press on the tabulation key will expand a small keyword into a chunk of pre-written code easy to navigate through and modify.
|
||||
|
||||
### 5. Org-mode ###
|
||||
|
||||
|
||||
|
||||
For disclaimer, I have only recently started using Org-mode. But it has already blown me away. From the hundreds of written pieces I have seen around, Org-mode can change your life. The idea behind it is simple: it is a mode that simplifies note taking while keeping a plain text format, making it easy to navigate through lists of tasks and various data, and perform operations such as filtering by priority or due date, or setting a recurrence. Yet, from this simple idea, you can accomplish a lot, and it is easy to get overwhelmed with all the options. Rather than a long explanation, I urge you to go through [available tutorials][2], watch a lot of videos, and see by yourself how powerful Org-mode is.
|
||||
|
||||
### 6. Helm ###
|
||||
|
||||
|
||||
|
||||
Some love it, but others are not such a big fan of it. I am part of the later. But with such a huge following, it is impossible to avoid it. Helm aims to transform your Emacs experience completely. Simply described, Helm is a framework that will help you find a file or a command quickly from within Emacs. Based on your input, it will try to use word completion to guide you to the action you have in mind. The feeling is a bit weird at first, but for some, Helm is a religion of its own. Although I am not its fan, I do appreciate helm-occur which a great tool to search for strings in a large document as it shows all occurrences in a separate buffer, making it easy to navigate through them. If you are looking for a quick demo to understand what Helm can do, I recommend [this post][3].
|
||||
|
||||
### 7. ace-jump-mode ###
|
||||
|
||||
|
||||
|
||||
Another plugin with a big following that I am trying to get on board with is ace-jump-mode. Master this plugin, and you will be promised to transcend the usage of a mouse. Simply described, by triggering ace-jump-mode with a shortcut of your choice, you will be prompted for a character. Enter one, and all words starting with that character will be highlighted with a unique letter. Enter one of the letters on screen, and your cursor will jump straight to the word it is highlighting. I have to admit that it is pretty hard to get the reflex to use it, but once you have it, it will increase your movement speed in a document by a lot.
|
||||
|
||||
### 8. find-file-in-project ###
|
||||
|
||||
|
||||
|
||||
If you like Sublime text and its very handy 'Ctrl-p' fuzzy search to open any file in a project, then you will love find-file-in-project (or ffip). After setting it up by declaring the root of your version control folder, you can summon easily a cool text bar that quickly scans and searches through your code base for a matching file based on the name you input. I like to have it bound to the F6 key on my keyboard. It is simple and very handy if you do not know the complicate directory structure from the top of your head.
|
||||
|
||||
### 9. Flymake ###
|
||||
|
||||
|
||||
|
||||
For IDE lovers, I think that syntax checker is one of the most powerful features. It is great for beginners and handy for tired programmers. And thanks to Flymake, Emacs users can enjoy it too. Since I work in PHP a lot, Flymake does not need any extra configuration. As I write my code, it will automatically check my code and highlight any line that contains a problem. For compiled languages, Flymake will look for a Makefile that it will use to check your code. Absolutely magical.
|
||||
|
||||
### 10. electric-pair ###
|
||||
|
||||
Last, but not least, electric-pair is one of the simplest yet most powerful plugin in my opinion. It just automatically closes whatever parenthesis or bracket you open. It doesn't look like much at first, but trust me. After struggling for the hundredth time to find that matching parenthesis, you will be glad to have a plugin to ensure that all your expressions are balanced.
|
||||
|
||||
To conclude, Emacs is a fantastic tool. Probably not a shocker. Try these plugins and watch as your productivity goes through the roof. This list is of course not exhaustive at all. If you want to bring your contribution, feel free to do so in the comments. I am myself always looking for new plugins to try and new ways to experience Emacs.

如何在 Fedora/CentOS/RHEL 或 Arch Linux 上安装 Cockpit
|
||||
================================================================================
|
||||
Cockpit 是一个免费开源的服务器管理软件，它使得我们可以通过它好看的 web 前端界面轻松地管理我们的 GNU/Linux 服务器。Cockpit 使得 linux 系统管理员、系统维护员和开发者能轻松地管理他们的服务器并执行一些简单的任务，例如管理存储、检测日志、启动或停止服务以及一些其它任务。它的报告界面添加了一些很好的功能使得可以轻松地在终端和 web 界面之间切换。另外，它不仅使得管理一台服务器变得简单，更重要的是只需要一个单击就可以在一个地方同时管理多个通过网络连接的服务器。它非常轻量级，web 界面也非常简单易用。在这篇博文中，我们会学习如何安装 Cockpit 并用它管理我们的运行着 Fedora、CentOS、Arch Linux 以及 RHEL 发行版操作系统的服务器。下面是 Cockpit 在我们的 GNU/Linux 服务器中一些非常棒的功能：
|
||||
|
||||
1. 它包含 systemd 服务管理器。
|
||||
2. 有一个用于故障排除和日志分析的 Journal 日志查看器。
|
||||
3. 包括 LVM 在内的存储配置比以前任何时候都要简单。
|
||||
4. 用 Cockpit 可以进行基本的网络配置。
|
||||
5. 可以轻松地添加和删除用户以及管理多台服务器。
|
||||
|
||||
### 1. 安装 Cockpit ###
|
||||
|
||||
首先，我们需要在我们基于 linux 的服务器上安装 Cockpit。大部分发行版的官方软件仓库中都有可用的 cockpit 安装包。这篇博文中，我们会在 Fedora 22、CentOS 7、Arch Linux 和 RHEL 7 中通过它们的官方软件仓库安装 Cockpit。
|
||||
|
||||
#### CentOS / RHEL ####
|
||||
|
||||
CentOS 和 RHEL 官方软件库中有可用的 Cockpit。我们只需要用 yum 管理器就可以安装。只需要以 sudo/root 权限运行下面的命令就可以安装它。
|
||||
|
||||
# yum install cockpit
|
||||
|
||||
|
||||
|
||||
#### Fedora 22/21 ####
|
||||
|
||||
和 CentOS 一样， Fedora 的官方软件库默认也有可用的 Cockpit。我们只需要用 dnf 软件包管理器就可以安装 Cockpit。
|
||||
|
||||
# dnf install cockpit
|
||||
|
||||
|
||||
|
||||
#### Arch Linux ####
|
||||
|
||||
现在 Arch Linux 官方软件库中还没有可用的 Cockpit，但 Arch 用户库（Arch User Repository，AUR）有。只需要运行下面的 yaourt 命令就可以安装。
|
||||
|
||||
# yaourt cockpit
|
||||
|
||||
|
||||
|
||||
### 2. 启动并启用 Cockpit ###
|
||||
|
||||
成功安装完 Cockpit，我们就要用服务/守护进程管理器启动 Cockpit 服务。到了 2015 年，尽管一些 linux 发行版仍然运行 SysVinit 管理守护进程，但大部分 linux 发行版都采用了 Systemd，Cockpit 使用 systemd 完成从运行守护进程到服务几乎所有的功能。因此，我们只能在运行着 Systemd 的最新的 linux 发行版中安装 Cockpit。要启动 Cockpit 并让它在每次系统重启时自动启动，我们需要在终端或控制台中运行下面的命令。
|
||||
# systemctl start cockpit
|
||||
|
||||
# systemctl enable cockpit.socket
|
||||
|
||||
创建从 /etc/systemd/system/sockets.target.wants/cockpit.socket 到 /usr/lib/systemd/system/cockpit.socket 的符号链接。
|
||||
|
||||
### 3. 允许通过防火墙 ###
|
||||
|
||||
启动 Cockpit 并使得它能在每次系统重启时自动启动后，我们现在要给它配置防火墙。由于我们的服务器上运行着防火墙程序，我们需要允许它通过某些端口使得从服务器外面可以访问 Cockpit。
|
||||
|
||||
#### Firewalld ####
|
||||
|
||||
# firewall-cmd --add-service=cockpit --permanent
|
||||
|
||||
success
|
||||
|
||||
# firewall-cmd --reload
|
||||
|
||||
success
|
||||
|
||||
|
||||
|
||||
#### Iptables ####
|
||||
|
||||
# iptables -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
|
||||
|
||||
# service iptables save
|
||||
|
||||
### 4. 访问 Cockpit Web 界面 ###
|
||||
|
||||
下面，我们终于要通过 web 浏览器访问 Cockpit web 界面了。根据配置，我们只需要用浏览器打开 https://ip-address:9090 或 https://server.domain.com:9090。在我们这篇博文中，我们用浏览器打开 https://128.199.114.17:9090，正如下图所示。
|
||||
|
||||
|
||||
|
||||
此时会出现一个 SSL 认证警告，因为我们正在使用一个自签名认证。我们只需要忽略这个警告并进入到登录页面，在 chrome/chromium 中，我们需要点击 Show Advanced 然后点击 **Proceed to 128.199.114.17 (unsafe)**。
|
||||
|
||||
|
||||
|
||||
现在，要进入仪表盘，我们需要输入详细的登录信息。这里，用户名和密码和用于登录我们的 linux 服务器的用户名和密码相同。当我们输入登录信息并点击 Log In 按钮后，我们就会进入到 Cockpit 仪表盘。
|
||||
|
||||
|
||||
|
||||
这里我们可以看到所有的菜单以及 CPU、磁盘、网络、存储使用情况的可视化结果。仪表盘正如上图所示。
|
||||
|
||||
#### 服务 ####
|
||||
|
||||
要管理服务，我们需要点击 web 页面右边菜单中的 Services 按钮。然后，我们会看到服务被分成了 5 个类别，目标、系统服务、套接字、计时器和路径。
|
||||
|
||||
|
||||
|
||||
#### Docker 容器 ####
|
||||
|
||||
我们甚至可以用 Cockpit 管理 docker 容器。用 Cockpit 监控和管理 Docker 容器非常简单。由于我们的服务器中没有安装运行 docker，我们需要点击 Start Docker。
|
||||
|
||||
|
||||
|
||||
|
||||
Cockpit 会自动在我们的服务器上安装和运行 docker。启动之后，我们就会看到下面的截图。然后我们就可以按照需求管理 docker 镜像、容器。
|
||||
|
||||
|
||||
|
||||
#### Journal 日志查看器 ####
|
||||
|
||||
Cockpit 有个日志查看器，它把错误、警告、注意分到不同的标签页。我们也有一个 All 标签页，在这里可以看到所有的日志信息。
|
||||
|
||||
|
||||
|
||||
#### 网络 ####
|
||||
|
||||
在网络部分，我们可以看到两个可视化发送和接收速度的图。我们可以看到这里有一个可用网卡的列表，还有 Add Bond、Bridge、VLAN 的选项。如果我们需要配置一个网卡，我们只需要点击网卡名称。在下面，我们可以看到网络的 Journal 日志信息。
|
||||
|
||||
|
||||
|
||||
#### 存储 ####
|
||||
|
||||
现在，用 Cockpit 可以方便地查看硬盘的读写速度。我们可以查看存储的 Journal 日志以便进行故障排除和修复。在页面中还有一个已用空间的可视化图。我们甚至可以卸载、格式化、删除一块硬盘的某个分区。它还有类似创建 RAID 设备、卷组等攻能。
|
||||
|
||||
|
||||
|
||||
#### 用户管理 ####
|
||||
|
||||
通过 Cockpit Web 界面我们可以方便地创建新用户。在这里创建的账户会应用到系统用户账户。我们可以用它更改密码、指定角色、以及删除用户账户。
|
||||
|
||||
|
||||
|
||||
#### 实时终端 ####
|
||||
|
||||
Cockpit 还有一个很棒的特性。是的，我们可以执行命令，用 Cockpit 界面提供的实时终端执行任务。这使得我们可以根据我们的需求在 web 界面和终端之间自由切换。
|
||||
|
||||
|
||||
|
||||
### 总结 ###
|
||||
|
||||
Cockpit 是由 [Red Hat][1] 开发的使得管理服务器变得轻松简单的免费开源软件。它非常适合于进行简单的系统管理任务和新手系统管理员。它仍然处于开发阶段，还没有稳定版发行。因此不适合于生产环境。它是针对最新的默认安装了 systemd 的 Fedora、CentOS、Arch Linux、RHEL 系统开发的。如果你想在 Ubuntu 上安装 Cockpit，你可以通过 PPA 访问，但现在已经过期了。如果你有任何疑问、建议，请在下面的评论框中反馈给我们，这样我们可以改进和更新我们的内容。非常感谢 ！

提高emacs（生产力）效率的最好插件是什么
|
||||
================================================================================
|
||||
一年前的这个时候, 我想要寻找一个最好的插件 [将VIM打造成一个成熟的全功能的IDE][1]. 有趣的是, 很多评论那篇文章的是关于Emacs是怎么样（如何）已经集成大部分这些插件,已经是一个伟大的IDE了. 尽管我对Emacs的难以置信的多样化表示赞成, 它依旧不是可以开箱即用（安装好不安插件即可用）的高级编辑器. 还好, 其庞大的插件库可以解决这个问题. 但在过多的选项中, 有时很难清楚该如何入手. 因此现在, 让我试着收集一个虽然简短但是不可或缺的插件列表来让你使用Emacs时提高工作效率. 虽然我主要侧重于与编程相关的生产力,但是这些插件将对任何人或对任何使用方法都是有用的.
|
||||
|
||||
### 1. Ido-模式 ###
|
||||
|
||||
|
||||
|
||||
Ido 或许是对新手最有用的一个插件, Ido 表示交互式的去做.它取代大部分的用花哨的匹配字符提示的枯燥菜单 . 好比说, 它将取代正常的提示来打开一个拥有当前目录中的所有文件列表的文件. 任何字符串类型,Ido 将尝试匹配最合适的文件。它很容易想象你的行为,并迅速通过一个文件夹的所有文件命名相同的前缀来查找.
|
||||
|
||||
### 2. Smex ###
|
||||
|
||||
|
||||
|
||||
不算最著名的一个,但却是一个好选择来完成那些由Ido-mode开始的工作:Smex可以优雅的替代正常的“M-x”提示,也有由Ido-mode带来的很大的启发。通常输入的命令调用“M-x”之后它带来同样的互动搜索。它既简单又有效,是一个很好的节省那些额外的你通常需要1秒的短时间方式
|
||||
|
||||
### 3. Auto Complete ###
|
||||
|
||||
|
||||
|
||||
知道这个插件的存在之前,我花了我一半的时间在使用Emacs敲击"M-/"来完成代码上。现在,我有一个漂亮的弹出为我去做自动补全。无须多说,只是我们都需要它。
|
||||
|
||||
### 4. YASnippet ###
|
||||
|
||||
|
||||
|
||||
这是真正的程序员所需利器。总有一些代码,我们觉得我们在它们上面用掉了所有的时间。对我来说,用"var_dump(…);exit;"来调试PHP。经过一段时间一遍又一遍的输入"var_dump(…);exit;",我就想到我可以预先把其作为录制好的,方便的代码片段。YASnippets,很容易导入片段文件或者自己制做。之后,一个简单的按制表键可以将一小关键词扩展成一块预先写好的代码易于使用者浏览和修改。
|
||||
|
||||
|
||||
### 5. Org-mode ###
|
||||
|
||||
|
||||
|
||||
免责声明,我最近才开始使用Org-mode。但它已经深深的吸引了我。从我看过数以百计的书面作品来说,Org-mode可以改变你的生活。它背后的想法很简单:它是一种模式,简化了笔记,同时保持一个纯文本格式,便于浏览列表的任务和各种数据,并执行操作,如按优先级过滤或到期日期,或设置一个复发日期 。然而,从这个简单的想法,你可以完成很多,但也容易被所有的选项弄的不堪重负。与其去看一个长长的解释,我敦促你去通过[可用教程][2],看很多视频,自己去看看Org-mode是多么强大。
|
||||
|
||||
|
||||
### 6. Helm ###
|
||||
|
||||
|
||||
|
||||
一些使用者喜欢它,但是其他人没有这么大的使用热情。我是后者的一部分。但在拥有这样一个庞大的追随者群体的情况下,是不可能避免提到它的。Helm旨在完全变换你的Emacs使用体验。简单描述,Helm是一个这样的框架,在Emacs下将帮助您快速找到一个文件或命令。根据您的输入,它将尝试使用词语自动完成指导你大脑的念头变为行动。起初感觉有点奇怪,但对一些人来说,Helm本身就是一个信仰。虽然我不是Helm的粉丝,我欣赏helm-occur这一个伟大的工具在一个大文档搜索字符串并且在一个单独的缓冲区显示所有,因此很容易导航。如果你正在寻找一个快速演示来了解Helm能做什么,我推荐这篇文章[3]。
|
||||
|
||||
|
||||
### 7. ace-jump-mode ###
|
||||
|
||||
|
||||
|
||||
另一个插件有一大群追随者,我试图加入ace-jump-mode的粉丝群。拥有这个插件,你会体验到胜于鼠标的使用。简单的描述,通过触发ace-jump-mode您选择的快捷方式,你将被提示字符。输入一个字符,所有单词将会出现,独特的字母字符将突出显示。输入一个字母在屏幕上,和你的光标会直接跳转到词高亮显示。我不得不承认,这是让反射很难使用它,但是,一旦你拥有它,它会增加你的在一个文档里光标的移动速度。
|
||||
|
||||
|
||||
|
||||
### 8. find-file-in-project ###
|
||||
|
||||
|
||||
|
||||
如果你喜欢Sublime text和它非常方便的“Ctrl-p”模糊搜索打开在一个项目中的任何文件,你将会喜欢上find-file-in-project(或ffip)。通过声明您的版本控制的根文件夹设置后,您可以轻松地收集一个快速扫描的很酷的标题文本并根据您输入的名称匹配的通过代码库搜索文件。我喜欢把它绑定到键盘上面F6键。如果你不知道从你的顶层目录到最基本文件的复杂结构，它很简单,很方便。
|
||||
|
||||
|
||||
### 9. Flymake ###
|
||||
|
||||
|
||||
|
||||
IDE的爱好者,我认为语法检查器是IDE最强大的特性之一。它非常适合初学者和方便码累了的程序员。感谢Flymake,Emacs用户也可以享受语法检查器 。因为我工作很多需要PHP,Flymake不需要任何额外的配置。当我写代码的时候,它会自动检查我的代码和高亮任何一个包含一个问题的行。对于编译语言,Flymake将寻找一个Makefile,它将用来检查代码。绝对不可思议。
|
||||
|
||||
|
||||
|
||||
### 10. electric-pair ###
|
||||
|
||||
最后,但并非最不重要,在我看来，electric-pair是最简单但最强大的插件之一。它就自动关闭括号或打开括号。它期初看起来不是很好,但相信我。第一百次挣扎后发现匹配的括号,你会很高兴有一个插件,确保你所有的表达式都是平衡的。
|
||||
|
||||
|
||||
|
||||
总结一下,Emacs是一个奇妙的工具。这可不是一个令人惊哑的说法。试试这些插件和看着你的效率直线飙升。这当然不是详尽的列表。如果你想带来你的贡献,请在评论中这样做。我自己一直在寻找新的插件来体验Emacs，也在找寻新方法来体验Emacs。
