[英]Emacs regex search then write
I would like to find/extract a group in each line of a buffer, then write it to a new buffer. 我想在缓冲区的每一行中查找/提取一个组,然后将其写入新的缓冲区。
So in my comma-delimted data file, my lines basically look like this: 因此,在逗号分隔的数据文件中,行基本上如下所示:
'A-field','B-field','C-field','D-field'
ie, four single-quoted fields of data per line. 即每行四个单引号的数据字段。 I want to extract the quoted B-field and write it to a new buffer.
我想提取引用的B字段并将其写入新的缓冲区。
Is it possible at the elisp repl to extract from one buffer and write that to a new buffer? elisp repl是否有可能从一个缓冲区中提取并将其写入新缓冲区? Or is this something you'd write as a stand-alone .el file then call from the buffer (M-my-extract-write) from the mini-buffer?
还是这是您要编写为独立的.el文件,然后从迷你缓冲区从缓冲区调用(M-my-extract-write)的东西?
Here's one way to do that: 这是一种方法:
Cu Cs ^[^,]*,'\\([^']*\\)',.* M-% \\1 RET !
Cu Cs ^[^,]*,'\\([^']*\\)',.* M-% \\1 RET !
. I recommend multiple-cursors + sexp movements for stuff like this. 对于这种事情,我建议使用多光标 + sexp运动。
Macros also work well, but the immediate feedback of multiple-cursors is nice. 宏也可以很好地工作,但是多光标的即时反馈很好。
Writing elisp to handle simple repetitive tasks is overkill. 编写elisp来处理简单的重复任务实在是太过分了。
