如何才能使emacs自动插入闭式大括号 [英] How can can I get emacs to insert closing braces automatically
问题描述
void foo()< cursor> ;
我想输入{来导致这种情况发生
void foo(){
< cursor>
}
我希望这只能在cc模式下发生,只有在结束一行,当不在一个字符串/评论/ etc
首先要想到的是重新绑定{来做这个(我可以弄清楚如何自己这样做),但是很难让它只在正确的时间发生。
任何提示都将不胜感激。
这样做:
(defun my- c-mode-insert-lcurly()
(interactive)
(插入{)
(let((pps(syntax-ppss)))
(eolp)(不是(或(nth 3 pps)(nth 4 pps))));; EOL而不是字符串或注释
(c-indent-line)
(插入\\\
(c-indent-line)
(forward-line -1)
(c-indent-line))))
(define-key c-mode-base-map{'my-c-mode-insert-lcurly)
I've just started using emacs, and there's one feature I'd really like, and searching around a bit was fruitless. I hope someone else has done this because I don't want to learn elisp just yet.
void foo()<cursor>
I would like typing an "{" to cause this to happen
void foo(){
<cursor>
}
I would like this to only happen in cc-mode, and only at the end of a line when not in a string/comment/etc
The first thing that came to mind was rebinding "{" to do this always(I could figure out how to do this myself), but it would be hard to make it only happen at the right time.
any hints would be appreciated.
This will do it:
(defun my-c-mode-insert-lcurly ()
(interactive)
(insert "{")
(let ((pps (syntax-ppss)))
(when (and (eolp) (not (or (nth 3 pps) (nth 4 pps)))) ;; EOL and not in string or comment
(c-indent-line)
(insert "\n\n}")
(c-indent-line)
(forward-line -1)
(c-indent-line))))
(define-key c-mode-base-map "{" 'my-c-mode-insert-lcurly)
