更改 Eclipse 自动完成(内容辅助)的行为 [英] Changing the behavior of the Eclipse auto-complete (Content Assist)

问题描述

当我在 Eclipse 中编程时，自动完成建议框通常在键入一个点时打开(例如在键入 System. 或 SomeObject. 后，并停留键入与任何建议类似的代码时打开.

这就是我要说的:

我经常使用自动完成建议框来发挥我的优势，如果可能的话，为了提高我在编程时的工作效率，我想做出一些改变；

<小时>

• 有没有办法让建议框一直可见，实时显示建议(并在出现时显示一个空白框没有可用的建议)?

• 有什么方法可以向建议框添加永久的自定义建议(例如切换案例模板或一行代码，如 public String toString())?

• 有什么方法可以重新排列建议框的顺序(例如在通用函数之前的类私有变量或 System.out.print() 之前的 System.out.println())) ?

• 有什么方法可以重新设计建议框 - 即更改其文本颜色、背景颜色、重新调整建议框窗口的大小并删除黄色的 java-doc 弹出窗口?

解决方案

仅供参考，在 Eclipse 术语中，此功能称为 Content Assist.

不，这不可能.您可以随时通过 Ctrl+Space(Mac 上为 Command+Space)调用它

是的，您可以通过Preferences > Java > Editor > Templates

不是真的.通过 Preferences > Java > Content Assist > Advanced 可以对通过提案类型循环"的顺序进行一些控制>，但这并不是您真正要寻找的.我认为，提案的顺序基于调用 Content Assist 的当前上下文.

有什么方法可以重新设计建议框 - 即更改其文本颜色、背景颜色、重新调整建议框窗口的大小并删除黄色的 java-doc 弹出窗口?

所有自定义选项都可以在Preferences > Java > Content Assist 下使用；颜色选项在 Preferences > General > Appearance > Color and Fonts 下可用，但我认为它的颜色弹出窗口可能来自您的操作系统颜色设置.

When I am programming in Eclipse, the auto-complete suggestions box usually opens when typing a dot (for example after typing System. or SomeObject., and stays open while typing a similar code to any of the suggested.

This is what I'm talking about:

I often use the auto-complete suggestions box to my advantage, and there are couple of changes I would like to make in order to improve my productivity while programming, if possible;

---

• Is there any way to make the suggestions box visible all the time, showing suggestions in real-time (and showing a blank box when there are no available suggestions) ?

• Is there any way to add permanent custom suggestions to the suggestions box (e.g. a switch case template or a line of code like public String toString()) ?

• Is there any way to re-order the suggestions box (e.g. class private variables before general functions or System.out.println() before System.out.print()) ?

• Is there any way to re-design the suggestions box - i.e changing its text color, background color, re-sizing the suggestions box window and removing the yellow java-doc pop-up?

解决方案

FYI, in Eclipse terminology this feature is called Content Assist.

Is there any way to make the suggestions box visible all the time, showing suggestions in real-time (and showing a blank box when there are no available suggestions) ?

No, that's not possible. You can invoke it any time you want via Ctrl+Space (Command+Space on Mac)

Is there any way to add permanent custom suggestions to the suggestions box (e.g. a switch case template or a line of code like public String toString()) ?

Yes, you can add your own templates via Preferences > Java > Editor > Templates

Is there any way to re-order the suggestions box (e.g. class private variables before general functions or System.out.println() before System.out.print()) ?

Not really. There is some control of the order for "cycling" through proposal types via Preferences > Java > Content Assist > Advanced, but it's not really what you're looking for. The order of proposals is, I think, based on the current context of when Content Assist is invoked.

Is there any way to re-design the suggestions box - i.e changing its text color, background color, re-sizing the suggestions box window and removing the yellow java-doc pop-up?

All of the customization option are available under Preferences > Java > Content Assist; color options are available under Preferences > General > Appearance > Color and Fonts, but I think the colors for that pop-up might come from your operating system color settings.

If you're using (or willing to use) Eclipse Juno (4.2) then there is a new project call Code Recommenders that you might find interesting.
