How is Atom different from Sublime? Atom is an open source text editor/IDE, built on JavaScript/HTML/CSS. Sublime Text is a commercial product, built on C/C++ and Python. Comparable to Atom is Adobe Brackets, another open source text editor/IDE built on JavaScript/HTML/CSS. Be minded that this makes Brackets more oriented towards Web development, specially in the front end. Advantages of open source projects are faster rate of development and, of course, price. Does it include IDE features like build tools, function definition jumps, documentations, etc.? The short answer is yes, yes, and yes. The app is completely modular. Open source will give people the freedom to fill the gaps on several of these features. Has anyone using Sublime got a Beta invitation to point out the differences? Advantages of Atom is entry-level hackability, since it's built on the same code that powers Web sites. Advantages of Sublime Text is performance, as it doesn't need to run on top of Node.js, and it's a more mature product, about to reach a stable version 3. There are a long list of minor differences that can be included in the comments (I wish this markdown could be able to draw a table for comparisons, but that's another issue). Because of Atom's rapid turnout, I am afraid some of differences I list here will become outdated over time. Per example, at the time of this writing, Atom is only available on the Macintosh while Sublime Text is already multiplatform. Can I use the themes, schemes and packages from Sublime as is, like Sublime could do with text mate. The short answer is no, but because of Atom's hackability, it will be easy to retool packages from other editors to Atom.

到目前为止还没有人指出的一个主要区别是(至少在Windows上)Atom不完全支持除US之外的其他键盘布局，这对一些人来说可能很重要。有一份关于这个漏洞的报告，几百个帖子已经开放了一年多(https://github.com/atom/atom-keymap/issues/35)。

可能与选择编辑有关。

我今天刚收到测试邀请，马上试用了亚当。GUI感觉像Sublime，是的，有一些捷径采用了Sublime。

除了上面提到的这些，我还发现了一些不同之处:

Vim mode is not as good as the Vintage mode on Sublime (which is not a fully featured vim either) because the vim package is in an early stage of development. See https://atom.io/packages/vim-mode for detail. As James mention, Atom is written using web tools, so you have access to the stylesheet of the text editor (styles.less) to do whatever appearance changes you want using CSS. There is also an option to change the startup CoffeeScript. Again, because Atom is still in the beta stage, Sublime has much more native plugin packages. However, since Atom is written in Node.js, the Atom official site said you can "choose from over 50 thousand in Node's package repository." (Because I am not a Node.js pro, I haven't look into this feature though) Atom has better Github support out of the box, but Sublime has a several Git packages. Sublime is a paid application unlimited evaluation period. Atom is free at the beta stage but we don't know whether Github wants to charge it or not.

因此，Atom是一个在测试阶段使用web技术构建的文本编辑器。相比之下，Sublime经历了许多不同的迭代。Atom仍然缺少很多Sublime支持的包，所以问题是Atom会赶上Sublime还是会变得更好?Github似乎对这个文本编辑器的未来很有信心，因为它的底层技术很受欢迎，从长远来看，Atom可能会是Sublime的一个很好的替代品。

我尝试了Atom，它看起来真的很好，但有一个主要问题(至少在0.84版):

它不支持垂直选择Alt+拖动-这是每个现代代码编辑器必须的。

一个主要的区别是支持“印度字体”，也就是南亚脚本(包括高棉语、老挝语、缅甸语和泰国语等东南亚语言)。此外，对东亚语言(中文、日语、韩语)的支持也更好。这些是已知的错误(实际上是评分最高的错误)，已经存在多年了(东亚语言支持似乎以前工作得更好，但现在已经很难使用):

Atom是使用Node.js, CoffeeScript和LESS编写的。然后它被包装在WebKit包装器中，该包装器最初只适用于OSX，尽管现在也有Windows版本可用。(Linux版本必须从源代码构建，但Ubuntu用户有一个PPA。)

很多架构和功能都复制自Sublime Text，因为它们都经过了尝试和测试。插件系统的工作原理几乎是一样的，但是通过公开新的api也打开了许多新特性和潜力。

我相信，由于肌肉记忆，快捷键基本上保持不变——人们会记住它们，并能够立即点击Atom。

首选项可以通过GUI来控制，而不是直接编辑JSON，这可能会降低人们开始使用Atom的入门门槛。我自己发现很难导航所有这些，因为在首选项中没有搜索功能。
