Learn to use the JOE text editor on Linux
|
||||
======
|
||||
Joe's Own Editor (JOE) is a general text editor that is easy to learn
|
||||
and use.
|
||||
![Person programming on a laptop on a building][1]
|
||||
|
||||
I’m a fan of text editors that make it easy for you to learn how to use them. GNU nano is my favorite example of this: you launch nano, and you see a list of the most common commands along the bottom of the window throughout your entire session. Joe’s Own Editor (that’s `joe` for short) is another great example.
|
||||
|
||||
The `joe` editor uses a terminal-based interface, providing simple text editing capabilities and an easily accessible help screen. It’s written in C, it’s small with a hard dependency only on libc (ncurses is optional), and it’s licensed under the GPL.
|
||||
|
||||
### Installing
|
||||
|
||||
On Linux, you may be able to find JOE in your distribution’s software repository. It’s a little obscure, though, so not all distributions have packaged it. If that’s the case, you can download the source code from [SourceForge][2] and compile it yourself. It’s an easy process:
|
||||
|
||||
|
||||
```
|
||||
$ ./configure
|
||||
$ make
|
||||
$ sudo make install
|
||||
```
|
||||
|
||||
### Using JOE
|
||||
|
||||
According to its author, JOE takes inspiration from an application called WordStar and from [GNU Emacs][3]. Most of its basic editing keys are the same as WordStar shortcuts, and the editor itself strives to approximate WordStar. JOE also has some of the key bindings and features of GNU Emacs. This mix of two sources of inspiration can sometimes be disorienting, but then again, weaning yourself off Emacs (or your usual text editor of choice) under any circumstance can be disorienting. The important thing is that JOE offers help, and it’s easy to reach.
|
||||
|
||||
In the top right corner of JOE’s interface, there’s a persistent reminder that you can press **Ctrl+K** followed immediately by **H** to view a help screen. This is a toggle, so once you activate it, the help screen remains displayed at the top of your editor window until dismissed with the same key combo (**^KH** in JOE’s keyboard notation).
|
||||
|
||||
### Keyboard shortcuts
|
||||
|
||||
For all the pride JOE’s author takes in simulating a WordStar user experience, I have to admit it’s lost on me. I’d never heard of WordStar until I read about it in JOE’s documentation, and to me, it seemed to have a completely arbitrary keyboard shortcut scheme. Some are prefixed with **Ctrl+K** as an escape sequence, while others use **Esc** as the prefix, and still others require no escape sequence at all. I couldn’t determine the logic. Editing operations were just as likely as application options to require an escape sequence or not, and few of the letter associations made sense to me (**Ctrl+K** **D** for **save as**, for instance).
|
||||
|
||||
Luckily, JOE lets you cheat on keyboard shortcuts. Upon installation, JOE quietly creates a few symlinks for the `joe` executable. Included are:
|
||||
|
||||
* `jmacs` JOE with Emacs key bindings
|
||||
* `jpico` JOE with Pico (or GNU nano) key bindings
|
||||
* `rjoe` JOE with editing restricted only to the file passed to JOE at launch
|
||||
* `jstar` JOE with WordStar key bindings
|
||||
|
||||
|
||||
|
||||
![Black terminal with white text showing WordStar key bindings][4]
|
||||
|
||||
The persistent help menu remains, so if you’re ever unclear as to what functions you have available to you, refer to them with the help prompt at the top right of the screen. Of course, in Pico/nano mode, the main commands are always visible.
|
||||
|
||||
### Try JOE
|
||||
|
||||
JOE isn’t intended as a text editor you’ll never leave. It won’t become your IDE, email client, web browser, and file manager. In fact, it may not even be your main text editor for all tasks. It focuses on being good at one thing, and that’s general text editing.
|
||||
|
||||
JOE has all of the essential functions you need, like the ability to navigate your text quickly, the ability to select text, copy and paste, and so on. Give JOE a try, using your preferred symlink.

学习在 Linux 上使用 JOE 文本编辑器
|
||||
======
|
||||
Joe's Own Editor （JOE）是一款简单易学和使用的通用文本编辑器。
|
||||
![Person programming on a laptop on a building][1]
|
||||
|
||||
我很喜欢那些能让你轻松学会如何使用的文本编辑器。GNU nano 是我最喜欢的例子：你启动 nano，你会在整个会话的窗口底部看到一个最常用的命令列表。Joe's Own Editor（简称 `joe`）是另一个很好的例子。
|
||||
|
||||
`joe` 编辑器使用了一个基于终端的界面，提供了简单的文本编辑功能和一个易于访问的帮助屏幕。它用 C 语言编写，体积小，只对 libc 有硬性依赖（ncurses 是可选的），并且采用 GPL 授权。
|
||||
|
||||
### 安装
|
||||
|
||||
在 Linux 上，你也许能在你的发行版软件仓库中找到 JOE。虽然它有点晦涩，所以并不是所有的发行版都打包了它。如果是这样的话，你可以从 [SourceForge][2] 下载源码，然后自己编译。这是个简单的过程：
|
||||
|
||||
|
||||
```
|
||||
$ ./configure
|
||||
$ make
|
||||
$ sudo make install
|
||||
```
|
||||
|
||||
### 使用 JOE
|
||||
|
||||
据其作者介绍，JOE 的灵感来自于一个叫 WordStar 的应用和 [GNU Emacs][3]。它的大部分基本编辑键都与 WordStar 的快捷键相同，编辑器本身也在努力向 WordStar 靠拢。JOE 也有 GNU Emacs 的一些键绑定和功能。这种两种灵感来源的混合有时会让人迷惑，但话又说回来，在任何情况下，让自己脱离 Emacs（或你通常选择的文本编辑器）都会让人迷惑。重要的是，JOE 提供了帮助，而且很容易访问。
|
||||
|
||||
在 JOE 界面右上角，有一个持续的提示，你可以按 **Ctrl+K**，紧接着按 **H** 来查看帮助界面。这是一个切换键，所以一旦你激活它，帮助屏幕就会一直显示在你的编辑器窗口顶部，直到用同样的组合键（JOE 中的键盘符号为 **^KH**）解除。
|
||||
|
||||
### 键盘快捷键
|
||||
|
||||
尽管 JOE 的作者在模拟 WordStar 用户体验方面非常自豪，但我不得不承认，这对我来说是失落的。我从来没有听说过 WordStar，直到我在 JOE 的文档中读到了它，在我看来，它的键盘快捷键方案完全是任意的。有的用 **Ctrl+K** 作为转义序列的前缀，有的用 **Esc**作为前缀，还有的完全不需要转义序列。我无法确定其中的逻辑。编辑操作和应用选项一样，都有可能需要或不需要转义序列，而且很少有字母关联对我来说是有意义的（例如，**Ctrl+K** **D**代表**另存为**）。
|
||||
|
||||
幸运的是，JOE 可以让你在键盘快捷键上作弊。安装后，JOE 会悄悄为 `joe` 可执行文件创建一些符号链接。包括：
|
||||
|
||||
* `jmacs` JOE 使用 Emacs 键绑定
|
||||
* `jpico` JOE 使用 Pico （或 GNU nano） 键绑定
|
||||
* `rjoe` JOE 的编辑只限于启动时传递给 JOE 的文件
|
||||
* `jstar` JOE 使用 WordStar 键绑定
|
||||
|
||||
|
||||
|
||||
![Black terminal with white text showing WordStar key bindings][4]
|
||||
|
||||
持久的帮助菜单仍然存在，所以如果你不清楚有哪些功能可以使用，可以通过屏幕右上方的帮助提示来参考。当然，在 Pico/nano 模式下，主要命令总是可见的。
|
||||
|
||||
### 尝试 JOE
|
||||
|
||||
JOE 并不是一个你永远不会离开的文本编辑器，它不会成为你的 IDE、电子邮件客户端、网络浏览器和文件管理器。事实上，它甚至可能不是你所有任务的主要文本编辑器。它专注于做好一件事，那就是一般的文本编辑。
|
||||
|
||||
JOE 拥有你所需要的所有基本功能，比如能够快速浏览你的文本、能够选择文本、复制和粘贴等等。试试 JOE 吧，使用你喜欢的符号链接。
