刪除空白塊在Emacs

Question

我常常落得這樣的代碼塊：

public class CustomFile { 

    public String path; 
    public String name; 





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

我希望能夠把我的光標就行了上述public CustomFile並能夠刪除所有空白最多但不包括public String name;。有沒有可以讓我這樣做的命令或宏？

Answer 1

這看起來像你想要什麼：

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.
