問題描述

我想通過方法跳過我的 java 文件，例如當(dāng)我找到我的任何地方時，執(zhí)行一個鍵盤快捷鍵即可跳轉(zhuǎn)到方法的下一個結(jié)尾或方法的開頭.

I want to jump through my java files by method, e.g. when I've got my anywhere, do a single keyboard shortcut to jump to the next end of a method or beginning of a method.

Emacs 使用 C-M-a 和 C-M-e 的通過 defuns 移動"對 C 非常有用，并且完全符合我的要求.但顯然在 Java 中，一個 defun 是一個完整的類.

Emacs' "moving by defuns" with C-M-a and C-M-e is super-useful for C and does exactly what I want. But apparently in Java a defun is a whole class.

我發(fā)現(xiàn)我可以強(qiáng)制 C-M-f 和 C-M-b 做我想做的事.它們在任何括號平衡的表達(dá)式上前后移動.問題是它們只有在從方法定義的左括號或右括號之外調(diào)用時才具有我正在尋找的功能，這是極其有限的.

I've found that I can coerce C-M-f and C-M-b to sort of do what I want. They move forward and backward over any parentheses-balanced expression. The problem is that they only have the funcitonality I'm looking for when invoked from right outside the opening or closing brackets of a method definition, which is extremely limiting.

歡迎任何想法！

推薦答案

imenu 和 speedbar 與您要找的很接近.

imenu and speedbar are close to what you are looking for.

否則你可以自己定義.你可以這樣開始:

Otherwise you can define it by yourself. You can start with something like this:

(defvar java-function-regexp
  (concat
   "^[ 	]*"                                   ; leading white space
   "\(public\|private\|protected\|"        ; some of these 8 keywords
   "abstract\|final\|static\|"
   "synchronized\|native"
   "\|[ 	

]\)*"                          ; or whitespace
   "[a-zA-Z0-9_$]+"                            ; return type
   "[ 	

]*[[]?[]]?"                        ; (could be array)
   "[ 	

]+"                                ; whitespace
   "\([a-zA-Z0-9_$]+\)"                      ; the name we want!
   "[ 	

]*"                                ; optional whitespace
   "("                                         ; open the param list
   "\([ 	

]*"                             ; optional whitespace
   "\<[a-zA-Z0-9_$]+\>"                      ; typename
   "[ 	

]*[[]?[]]?"                        ; (could be array)
   "[ 	

]+"                                ; whitespace
   "\<[a-zA-Z0-9_$]+\>"                      ; variable name
   "[ 	

]*[[]?[]]?"                        ; (could be array)
   "[ 	

]*,?\)*"                          ; opt whitespace and comma
   "[ 	

]*"                                ; optional whitespace
   ")"                                         ; end the param list
))

(defun my:next-java-method()
  (interactive)
  (re-search-forward java-function-regexp nil t)
)

(defun my:prev-java-method()
  (interactive)
  (re-search-backward java-function-regexp nil t)
)

然后將 my:next-java-method 和 my:prev-java-method 綁定到你想去的任何鍵

Then bind my:next-java-method and my:prev-java-method to whatever key you want to go to the
