Try this Java file manager on Linux
|
||||
======
|
||||
|
||||
Computers are fancy filing cabinets, full of virtual folders and files waiting to be referenced, cross-referenced, edited, updated, saved, copied, moved, renamed, and organized. In this article, we're taking a look at a file manager for your Linux system.
|
||||
|
||||
At the tail end of the Sun Microsystem days, there was something called the Java Desktop System, which was strangely _not_ written in Java. Instead, it was a (according to sun.com at the time) "judicious selection of integrated and tuned desktop software, most based on open source and open standards." It was based on GNOME, with an office suite, email and calendaring apps, instant messaging, "and Java technology." I found myself musing about what it would take to create a desktop in Java. Objectively, a desktop doesn't actually consist of all that much. The general consensus seems to be that a desktop is made up of a panel, a system tray, an application menu, and a file manager.
|
||||
|
||||
It's an interesting thought exercise to imagine an actual Java desktop. Not enough to start an open source project with that as its aim, but enough for a quick web search for the necessary components. And as it turns out, someone has written and maintains a file manager in Java.
|
||||
|
||||
### JFileProcessor
|
||||
|
||||
The Java file manager I found is called JFileProcessor, or JFP for short. It's a fascinating exercise not just in Java, but specifically in [Groovy][1], a popular scripting language for Java.
|
||||
|
||||
![Image of the JfileProcessor folders.][2]
|
||||
|
||||
As a file manager, JFileProcessor takes a minimal approach to both design and function. It lets you view, open, move, copy, cut, or delete files on your local system and on remote systems. It's not particularly customizable, it doesn't have extra features like split panels or movable panes. It's not built around any central theme aside from managing files. JFileProcessor is refreshing, in a way, because of its simplicity. This is a file manager, and that's all. And sometimes that's all you want in a file manager.
|
||||
|
||||
I've written about options to [theme Java Swing][3] before, and that technique is technically an option for this open source application. However, I think part of the charm of this application is what OpenSolaris called its "Blueprint" theme. It's a nostalgic look of Java, and I've enjoyed running it in its native GUI appearance as a callback to my OpenSolaris (now OpenIndiana) laptop.
|
||||
|
||||
### User experience
|
||||
|
||||
Design aside, what really matters is user experience. JFileProcessor has just three buttons that you use on a daily basis: Up, back, and forward. They aren't bound to keyboard shortcuts, so you do have to click the buttons to navigate (or use the **Tab** key to select a button). I do a lot with keyboard shortcuts when using graphical applications, so this slowed me down a lot as I tried to navigate my system. However, there are times when I'm actually just lazily browsing files, and for that JFileProcessor worked exactly as I needed it.
|
||||
|
||||
There's a search component to JFileProcessor, too. As long as you set a reasonable starting folder, the search is quick and intelligent, allowing for both search globs and regex patterns. I used this feature regularly when searching for a specific e-book or comic archive or game rulebook, for instance, or any time that I had a rough idea that directory contained an item but couldn't be bothered to click all the way through to the destination. A quick search through the subdirectories inevitably returned the obvious result, and a double-click opened the file to whatever XDG preference I had set (Evince for PDFs, Foliate for eBooks, and so on.)
|
||||
|
||||
A right-click on any file or directory brings up a context menu. It's got most of the common tasks you'd expect: Copy, Cut, Paste, Delete, Rename, New. It's got some nice additions, too.
|
||||
|
||||
![Right-click context menu in JFileProcessor][4]
|
||||
|
||||
For instance, you can copy just the filename to your clipboard or save a path to a file. You can also run some scripts, including one to batch rename files, one to run a command on selected files, one to create a ZIP or TAR archive, and many more. And of course, there are several options for the coder, including opening a terminal at your current location and opening a new coding window.
|
||||
|
||||
### Install
|
||||
|
||||
I'm a real fan of Java. It's a clear language with sensible delimiters and a firm stance on cross-platform compatibility. I enjoy it as a language, and I love seeing what programmers create with it.
|
||||
|
||||
JFileProcessor is aptly named. It's an effective way to process files, in the sense that JFileProcessor gives you a simple window into the files of data on your system and allows you to interact with them, graphically, in the same way you're likely to interact with them from a terminal. It's not the most efficient file manager I've used, nor the one with the most features. However, it's a pleasant application that provides you with the basic tools you need for file management with a relatively small codebase that makes for some stellar afternoon reading.

在 Linux 上试试这个 Java 文件管理器
|
||||
======
|
||||
|
||||
计算机是奇特的文件柜，里面装满了等待引用、交叉引用、编辑、更新、保存、复制、移动、重命名和组织的虚拟文件夹和文件。在本文中，我将介绍一下 Linux 系统的文件管理器。
|
||||
|
||||
在 Sun Microsystem 时代的末期，出现了一种叫做 Java 桌面系统的东西，奇怪的是它_不是_用 Java 编写的。相反，它是（根据当时的 sun.com 上的描述）“对集成和优化的桌面软件的明智选择，大部分基于开源代码和开放标准”。它基于 GNOME，带有办公套件、电子邮件和日历应用、即时消息和“Java 技术”。我发现自己在思考用 Java 创建桌面需要什么。客观地说，桌面实际上并没有那么多。一般的共识似乎是桌面由面板、系统托盘、应用菜单和文件管理器组成。
|
||||
|
||||
想象一个实际的 Java 桌面是一个有趣的思维练习。不足以以此为目标启动一个开源项目，但足以在网络上快速搜索必要的组件。事实证明，有人用 Java 编写并维护了一个文件管理器。
|
||||
|
||||
### JFileProcessor
|
||||
|
||||
我找到的 Java 文件管理器叫做 JFileProcessor，简称 JFP。这不仅在 Java 中，而且在 [Groovy][1]（一种流行的 Java 脚本语言）中都是一项迷人的练习。
|
||||
|
||||
![Image of the JfileProcessor folders.][2]
|
||||
|
||||
作为文件管理器，JFileProcessor 在设计和功能上都采用了最小化的方法。它允许你查看、打开、移动、复制、剪切或删除本地系统和远程系统上的文件。它不是特别定制化的，它没有额外的功能，如拆分面板或可移动面板。除了管理文件外，它不围绕任何中心主题构建。JFileProcessor 在某种程度上令人耳目一新，因为它很简单。这是一个文件管理器，仅此而已。有时这就是你在文件管理器中想要的全部。
|
||||
|
||||
我之前写过关于[设置 Java Swing 主题][3]的方式，从技术上讲，该技术是这个开源应用的一个选项。但是，我认为这个应用的部分魅力在于 OpenSolaris 称之为 “Blueprint” 的主题。这是 Java 的怀旧外观，我喜欢以其原生 GUI 外观运行它，作为对我的 OpenSolaris（现为 OpenIndiana）笔记本电脑的回忆。
|
||||
|
||||
|
||||
### 用户体验
|
||||
|
||||
除了设计，真正重要的是用户体验。JFileProcessor 只有三个你日常使用的按钮：向上、后退和前进。它们未绑定到键盘快捷键，因此你必须单击按钮才能导航（或使用 **Tab** 键选择按钮）。在使用图形应用时，我经常使用键盘快捷键，所以当我尝试浏览我的系统时，这大大减慢了我的速度。但是，有时我实际上只是懒洋洋地浏览文件，因此 JFileProcessor 完全按照我的需要工作。
|
||||
|
||||
JFileProcessor 也有一个搜索组件。只要你设置合理的起始文件夹，搜索就会快速而智能，同时允许适用 glob 和正则模式搜索。例如，当我搜索特定的电子书或漫画档案或游戏规则手册时，或者任何时候我粗略地知道该目录包含一个项目但懒得一直点击到目的地址。在子目录中快速搜索，必然会得到明显的结果，然后双击打开文件，不管我设置了什么XDG偏好（Evince用于PDF，Foliate用于电子书，等等）。
|
||||
|
||||
右键单击任何文件或目录会弹出上下文菜单。它具有你期望的大部分常见任务：复制、剪切、粘贴、删除、重命名、新建。它也有一些不错的额外功能。
|
||||
|
||||
![Right-click context menu in JFileProcessor][4]
|
||||
|
||||
例如，你可以只将文件名复制到剪贴板或保存文件路径。你还可以运行一些脚本，包括用于批量重命名文件的脚本、用于对选定文件运行命令的脚本、用于创建 ZIP 或 TAR 存档的脚本等等。当然，编码器有多种选择，包括在当前位置打开终端和打开新的编码窗口。
|
||||
|
||||
### 安装
|
||||
|
||||
我是 Java 的忠实粉丝。它是一种清晰的语言，具有合理的分隔符和对跨平台兼容性的坚定立场。我喜欢它作为一种语言，我喜欢看到程序员用它创造的东西。
|
||||
|
||||
JFileProcessor 的名字很贴切。这是一种处理文件的有效方法，从某种意义上说，JFileProcessor 为你提供了一个简单的窗口来查看系统上的文件数据，并允许你以图形方式与它们进行交互，就像你可能在终端中与它们交互一样。它不是我用过的最高效的文件管理器，也不是功能最多的一个。然而，这是一个令人愉快的应用，为你提供了文件管理所需的基本工具，其相对较小的代码库使你可以在下午阅读一些精彩的内容。
