X-develop发布的几款IDE的比较，挺有意思～

Compared versions: X-develop 1.2, VS.NET 2003/2005¹, Resharper 1.5, IDEA 5.0, Eclipse 3.1

¹ available in a beta/preview version
² supported by third-party plugin
³ does not add anything to VS.net functionality

首先，所有的功能在X-develop一列中的支持结果都是Yes。这也算是理所当然的事情，人家怎么可能搬起石头砸自己的脚～但是，我总是觉得假假的， 呵呵。X-develop主要标榜的是自己的多语言支持性和多平台支持性，所以把Language Support和Platform Support放在了最前面，而且极度突出了自己在这两方面的优势。看着Eclipse一列那么多的No，我忍不住笑了出来，虽然在表格最后面的附注里面 有说supported by third-party plugin，但这多少有点儿愚民的感觉。
在Code analysis & Code editor一组中，吸引我的是Checking speed，Eclipse 是Medium，其他VS.NET + Resharper和IDEA都被无情的打上了Poor。Version control support是最搞笑的一组，X-develop看上去有巨大的优势，但是我很怀疑它所额外支持的东西是否比较有用。GUI designer和Unit testing也没有什么出奇的地方，X-develop支持那么多是因为它支持多语言，这是很正常的，不支持才不正常。
最让我眼前一亮的是Debugging中的Java debugger with Step back！这个可真的是个好东西，而且我也从来没在其他IDE中发现过。它强大的地方在于，在debug的时候可以让程序倒退着运行，这对观察程序行为， 调试很复杂或tricky的bug是很有用的。

看过之后总体感觉下来，X-develop面向的用户是没有深入使用其他主流IDE的开发人员。我个人是不会因为这些比较而改变我的IDE使用习惯，但是 在debug的时候，如果真的有很难调试的bug，我也许会到X-develop下面用Step back试试。另外再提一下，X-develop是要钱的，而且我还没找到crak... :(
