我认为这主要与开发者的认知范围有关。IDE提供了开发人员工作环境的宏观视图。您可以同时看到类层次结构、引用的资源、数据库模式、SDK帮助引用等。而且，由于您的击键会影响和影响如此多的事情，以及体系结构和体系结构交叉点的数量不断扩大，一次只使用一个代码岛工作变得越来越困难。

OTOH，“只有我和vim和手册页”让我对我的工作有了一个更精简的微观——但强烈而精确的——视图。如果我有一个用一种语言和一组静态库构建的设计良好、分区良好、稀疏耦合且高度内聚的代码库，那么这是可以的——这不是典型的情况，特别是当开发团队规模随着时间、距离和个人偏好而增长并重新构建代码结构时。

I'm currently working on projects in Flex and .NET. One of the nicer things about Flex is how few different ways there are to accomplish a standard thing - pull data from a database, open/close/read/write a file, etc. (Yet I'm using the Flex Builder/Eclipse IDE - a typical heavy-weight example like VS, because I'm still learning the basics and I need the training wheels. I expect to evolve back to vim once I'm confident of my patterns.) In this view, I can do what I need to do professionally by knowing a few things really really well.

OTOH, I can't imagine getting to that point with .NET because the view I'm expected to maintain keeps expanding and shifting. There much less conceptual integrity, and over several developers on a project over several months, much less consistency - but the IDE supports that, maybe encourages it. So the developer really needs to (and can more easily) know many more things adequately. Which also has the benefit of helping them answer (or even understand) a lot higher percentage of the questions on StackOverflow. I.e. we can have a deeper knowledge stack. And we can respond to a wider variety of help-wanted ads.

事情可能会朝着两个方向发展。也许对于“仅编辑器”作用域，这就像“如果你只有一把锤子，那么所有东西看起来都像钉子”。使用IDE方法，对于任何您想要固定在一起的东西，您都有广泛的紧固件和相关的工具范围可供选择- nals/锤子，螺钉/螺丝刀，螺栓/扳手，粘合剂/胶枪/夹子，磁铁等等-所有这些都在您的指尖(有向导帮助您开始)。

I'm not sure there's a clear dividing line between a text editor and an IDE. You have the likes of Notepad at one end of the scale, and the best modern IDEs at the other, but there are a lot of thing in between. Most text editors have syntax highlighting; editors aimed at programmers often have various other features such as easy code navigation and auto complete. Emacs even lets you integrate a debugger. The IDEs of even ten years ago had far less features to help programmers than you'd expect of a serious text editor these days.

使用ide的一个很好的理由是，它们是生产现代软件的公认方式。如果您不使用，那么您可能会使用“老式”的东西，如vi和emacs。这可能会导致人们得出结论——可能是错误的——你被困在自己的方式中，无法适应新的工作方式。在软件开发这样的行业——创意可能在短短几个月内就会过时——这是一种危险的状态。这可能会严重损害你未来的工作前景。

节省开发时间 通过提供集成调试、智能感知等功能，使生活更轻松。

有很多，但我会建议使用一个，他们比明显。

代码自动完成。它对探索代码有很大帮助。

简单地说，IDE提供了比简单编辑器更省时的特性。
