Emacs上的Eclipse缩进

Question

我是一名emacs用户,他刚刚开始为一家以eclipse为标准的新公司工作.我已经尝试过eclipse,但我也想尝试使用JDEE(经过长时间的中断后我回到了Java).到目前为止,主要的绊脚石是让缩进匹配.有没有一种简单的方法可以做到这一点,或者我是否需要深入研究emacs缩进的细节？

编辑:对不起这个问题的困惑:我不想让Eclipse模仿emacs,我想让emacs模仿Eclipse.我希望能够使用emacs来修改代码,而不会搞砸Eclipse用户期望的缩进.

我发现Eclipse(和IntelliJ)和Emacs默认java格式之间的主要区别在于Emacs将函数参数排成一行,并使用前面的参数继续到新行,例如emacs:

BigLongJavaStuff.doFoobarToQuux("argument 1",
                                "argument 2");

和Eclipse做:

BigLongJavaStuff.doFoobarToQuux("argument 1",
        "argument 2");

以下添加〜/ .emacs文件将使Emacs java-mode执行相同的操作:

;; eclipse-java-style is the same as the "java" style (copied from
;; cc-styles.el) with the addition of (arglist-cont-nonempty . ++) to
;; c-offsets-alist to make it more like default Eclipse formatting -- function
;; arguments starting on a new line are indented by 8 characters
;; (++ = 2 x normal offset) rather than lined up with the arguments on the
;; previous line
(defconst eclipse-java-style
  '((c-basic-offset . 4)
    (c-comment-only-line-offset . (0 . 0))
    ;; the following preserves Javadoc starter lines
    (c-offsets-alist . ((inline-open . 0)
                        (topmost-intro-cont    . +)
                        (statement-block-intro . +)
                        (knr-argdecl-intro     . 5)
                        (substatement-open     . +)
                        (substatement-label    . +)
                        (label                 . +)
                        (statement-case-open   . +)
                        (statement-cont        . +)
                        (arglist-intro  . c-lineup-arglist-intro-after-paren)
                        (arglist-close  . c-lineup-arglist)
                        (access-label   . 0)
                        (inher-cont     . c-lineup-java-inher)
                        (func-decl-cont . c-lineup-java-throws)
                        (arglist-cont-nonempty . ++)
                        )))
  "Eclipse Java Programming Style")
(c-add-style "ECLIPSE" eclipse-java-style)
(customize-set-variable 'c-default-style (quote ((java-mode . "eclipse") (awk-mode . "awk") (other . "gnu"))))

您需要在java模式下自定义缩进.看看这里,这里和这里.
