Eclipse：可以保存格式化代码吗？ [英] Eclipse: Can you format code on save?

问题描述

在Eclipse中， Windows - > 首选项 - > Java - > 代码样式，您可以定义用于注释和代码的代码模板，您可以设置代码格式化程序。

In Eclipse, under Windows -> Preference -> Java -> Code Style, you can define code templates for comments and code, and you can setup a code formatter.

我想知道在Eclipse中是否可能每次保存源文件时都会影响这些设置。基本上，我不希望突出显示所有内容，而是按 Ctrl + Shift + F ，我希望Eclipse负责确保我的代码格式正确

I'm wondering if it is possible in Eclipse to have these setting take affect every time I save a source file. Basically, instead of me highlighting everything and pressing Ctrl+Shift+F, I want Eclipse to be responsible for making sure my code is formatted properly.

这是可能的，您如何设置？

Is this possible and how do you set it up?

注意使用自动-Format：最好选择格式化编辑行，因为当重新格式化已经没有格式化的源代码控制的整个文件时，合并更改变得非常困难。

Note On Using the Auto-Format: It's probably best to choose "Format Edited Lines" as merging changes becomes very difficult when you reformat a whole file that is in source control already that was not formatted properly. Already did this to a co-worker.

推荐答案

在首选项下，选择 Java - > 编辑器 - > 保存操作。检查在保存上执行所选的操作，并检查格式源代码框。

Under Preferences, choose Java --> Editor --> Save Actions. Check the Perform the selected actions on save, and check the Format source code box.

这可能或可能在以前的Eclipse版本中不可用。我知道它有效：

This may or may not be available in previous versions of Eclipse. I know it works in:

Version: 3.3.3.r33x_r20080129-_19UEl7Ezk_gXF1kouft<br>
Build id: M20080221-1800
