Emacs宏生成序列？ [英] Emacs macro to generate a sequence?

问题描述

我正在阅读有关如何创建vi宏的文章：
vi序列宏，我看到一个有用的宏在缓冲区中创建一个序列。

I was reading this article on how to create vi macros: vi sequence macro and I saw one useful macro to create a sequence in the buffer.

1。

2.

...

100.

1.
2.
...
100.

vi，诀窍是可以在一个数字上击中ctrl-a，它会添加一个，所以这使得宏变得容易。我想在emacs中做同样的事情。

In vi, the trick is that one can hit ctrl-a over a number and it will add one to it, so this made the macro easy. I want to be able to do the same thing in emacs.

推荐答案

如果你使用Emacs 23（也许22？） ，默认情况下使用 kmacro-insert-counter 绑定到 Cx Ck TAB 。所以，你可以这样做：

If you are using Emacs 23 (and maybe 22?), use kmacro-insert-counter which is bound to C-x C-k TAB by default. So for your example, you'd do:

Cx（Cx Ck TAB。RET Cx）

所以启动宏，插入计数器后跟'。'，换行符，结束宏。然后 Cx eeeeeee 等或 M-1 0 0 Cx e 获得100个。

So start macro, insert counter followed by '.', newline, end macro. Then C-x e e e e e e e etc. Or M-1 0 0 C-x e to get 100 of them.

编辑：

忘了提到你可以将计数器设置为初始值。例如从1开始而不是0开始 M-1 Cx Ck Cc 。

Forgot to mention you can set the counter to an initial value also. For example to start at 1 instead of 0 do M-1 C-x C-k C-c.

如果你不不要让计数器在某个特定的点增加，前缀为 Cu 。在这一点上，当然击键会变得有点可笑，所以我通常用一个键来插入，但不要增加。

And if you don't want the counter to increment at a particular point, prefix it with C-u. Of course the keystrokes are getting a bit ridiculous at this point, so I usually bind a key to insert-but-don't-increment.
