在Eclipse中输入前进的自动完成 [英] Type ahead autocompletion in Eclipse

问题描述

Eclipse可以使用像Visual Studio一样的前端自动完成插件，所以我不必一直按 Ctrl + 空格来销毁空格键。 （如果你不知道它在Visual Studio中的工作原理，请不要麻烦回答）。

而且，我可以将自动填充限制为导入的包，比地球上的每一个Java类？当我和GWT一起工作时，看到了awt和swing等的建议。而且我不想将每个Java类添加到过滤器中，这只是愚蠢的。 （再次，就像在Visual Studio中做的一样）

解决方案

关于你的第二部分，，通过重新定义方法 getCompletionProposalAutoActivationCharacters（），需要一个触发表示完成的字符列表（再次，不是您要查找的）。 >

2011年11月更新：

Cristi 在他的回答（upvoted）中提到了一个很好的解决方法，其中包括将所有字母添加为java的自动激活触发器。

另请参见自动打开完成窗口在Eclipse 。

从线程 Eclipse自动完成：

  Windows  - >偏好 - > Java  - >编辑 - >内容辅助
  

• 将延迟设置为：0 （实际上> 0是更好的：50，它避免了CPU选择，因为不断的收听）


• 设置触发器为：

 
。（abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUV WXYZ @ 
 

Do Eclipse have a plugin for type ahead autocompletion like Visual Studio, so I don't have to destroy my spacebar by pressing Ctrl+Space all the time? (If you don't know how it works in Visual Studio, please don't bother answering.)

And also, can I limit the autocomplete to imported packages, rather than every single Java class on earth? It's fustrating seeing suggestions from awt and swing etc., when I'm working with GWT. And I don't want to add every single Java class to the filter, that's just stupid. (Again, like how it's done in Visual Studio!)

解决方案

Regarding your second part, yes you can

• Open Eclipse
• Select Window/Preferences from the menu
• Expand Java/Appearance/Type Filters from the menu on the left
• Click the "Add package" button, enter "java.awt" (without the quotes) and click OK
• OK your way out

This will make Eclipse remove any matching classes from the java.awt package from your type ahead list. Very nice...

So "type-ahead" exists in Eclipse (mentioned in this status report in June 2006), but is synonym of auto-completion, most often triggered by CTRL+ Space... (which is not exactly what you are looking for)

---

To be more specific, the kind of automatic auto-completion (completion while you are typing, with a "Common" or "All" list of possible completions) you have in Visual Studio is not there in Eclipse (actually read below):

Original answer January 2010:

At least, not without a dedicating plugin.
And even with that plugin, it would have to follow a TemplateCompletionProcessor, meaning it would need a list of characters triggering said completion (again, not what you are looking for), by redefining method getCompletionProposalAutoActivationCharacters().

Update November 2011:

Cristi mentions in his answer (upvoted) a great workaround, which consists adding all the letters as Auto activation triggers for java.
See also "Automatically opening completion window in Eclipse".

From the thread "Eclipse auto-completion ":

Windows -> Preferences -> Java -> Editor -> Content Assist

• Set delay to: 0 (actually >0 is better: 50, it avoids CPU picks because of constant listening)
• Set triggers to:

    .(abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUV WXYZ@
