删除Emacs中的空白块

Question

我经常会遇到像这样的代码块：

public class CustomFile {

    public String path;
    public String name;





    public CustomFile (String pathToFile, String dbName) {
    path = pathToFile;
    name = dbName;
    }
}

我希望能够将光标放在public CustomFile上方的行上，并且能够删除所有空格，但不包括public String name;。是否有允许我这样做的命令或宏？

Answer 1

这看起来像你想要的：

C-x C-o runs the command delete-blank-lines, which is an interactive
compiled Lisp function in `simple.el'.

It is bound to C-x C-o.

(delete-blank-lines)

On blank line, delete all surrounding blank lines, leaving just one.
On isolated blank line, delete that one.
On nonblank line, delete any immediately following blank lines.
