如何使用emacs重构C ++源代码？ [英] How can I refactor C++ source code using emacs?

问题描述

我感兴趣的主要是C ++和方法/类名/签名自动更改。

I'm interested mostly in C++ and method/class name/signature automatic changes.

推荐答案

，所以我也一直在等待其他回复。

I do this a lot, so I'm axiously awaiting other replies too.

我知道的唯一的技巧是基本的。这是我在Emacs重构代码时最好的朋友：

The only tricks I know are really basic. Here are my best friends in Emacs when refactoring code:

M-x query-replace

这允许您进行全局搜索和替换。

This allows you to do a global search and replace. You'll be doing this a ton when you move methods and commonly-accessed data to other classes or namespaces.

C-x 3

这样可以显示两个并排的缓冲区。然后，您可以继续加载其中的不同文件，并使用 C-x o 将光标从一个移动到另一个。这是很基本的东西，但我提到它，因为它使下一个有多么强大...

This gives you a display with two buffers side-by side. You can then proceed to load different files in them, and move your cursor from one to the other with C-x o. This is pretty basic stuff, but I mention it because of how powerful it makes the next one...

C-x (
(type any amount of stuff and/or emacs commands here)
C-x )

这是如何在emacs中定义一个宏。任何时候，你发现自己需要做同样的事情一遍又一遍的代码（它对于查询替换太复杂），这是一个救命。如果你搞错了，可以按 Cg 停止宏定义，然后撤消（ C -_ ），直到你回到你开始的地方。调用宏的键是 C-x e 。如果你想多次做，你可以点击 Esc ，然后输入一个数字。例如： Esc 100 Cx e 将尝试调用您的宏100次。

This is how you define a macro in emacs. Any time you find yourself needing to do the same thing over and over to a bunch of code (and it is too complex for query-replace), this is a lifesaver. If you mess up, you can hit C-g to stop the macro definition, and then undo (C-_) until you are back to where you started. The keys to invoke the macro are C-x e. If you want to do it a bunch of times, you can hit Esc and type in a number first. Eg: Esc 100 C-x e will try to invoke your macro 100 times.

通过按Esc键或按住Alt）获得Meta。

(Note: On Windows you can get "Meta" by hitting the Esc key, or holding down Alt).
