emacs 字符串插入矩形数字向量? [英] emacs string-insert-rectangle vector of numbers?
问题描述
如何使用 emacs 字符串插入矩形操作将数字向量添加到一系列行中?例如，我的 emacs 缓冲区中有一堆文本条目的缩短版本:
How can I use emacs string-insert-rectangle operation to add a vector of numbers to a series of lines? For example, I've got this shortened version of a bunch of text entries in my emacs buffer:

如何在 emacs 中使用类似 string-insert-rectangle 之类的东西来添加这个新的第三列，并增加数量?
How can I use something like string-insert-rectangle in emacs to add this new third column with increasing number count?
PS:我知道我可以用 bash/perl/python/etc 脚本来做到这一点，在这个问题中，我问这是否可以用 emacs 轻松完成.
PS: I know I could do this with a bash/perl/python/etc script, in this question I am asking if this can be easily done with emacs.
推荐答案
我觉得最简单的解决办法是在第一行标记原第三列的第一个字符，将点移到最后一行的同一个字符上，然后然后输入:
I think the simplest solution is to mark the first character of the original third column in the first line, move point to the same character of the last line, and then type:
CuCxrNRET id%d RET
rectangle-number-lines 是一个交互式编译的 Lisp 函数`rect.el'.
rectangle-number-lines is an interactive compiled Lisp function in `rect.el'.
它绑定到 C-x r N.
It is bound to C-x r N.
(rectangle-number-lines START END START-AT &optional FORMAT)
(rectangle-number-lines START END START-AT &optional FORMAT)
在区域矩形前插入数字.
Insert numbers in front of the region-rectangle.
START-AT，如果非零，应该是一个开始的数字数数.FORMAT，如果非零，应该是要传递的格式字符串与行数一起格式化".交互调用时带前缀参数，提示 START-AT 和 FORMAT.
START-AT, if non-nil, should be a number from which to begin counting. FORMAT, if non-nil, should be a format string to pass to `format' along with the line count. When called interactively with a prefix argument, prompt for START-AT and FORMAT.
regexp-replace 和宏技术都是需要了解的极好的通用工具，但矩形数字线几乎是为这个问题定制的.
The regexp-replace and macro techniques are both superb general-purpose tools to know, but rectangle-number-lines is pretty much custom-built for this very question.
编辑:当时我没有注意到，但事实证明这是 Emacs 24 中的一个新功能.早期版本的 Emacs 会将这个序列转换为 Cx rn(小写 n)运行一个完全不同的函数.
Edit: I hadn't noticed at the time, but it turns out that this is a new feature in Emacs 24. Earlier versions of Emacs will translate that sequence to C-x r n (lower-case n) which runs an entirely different function.
