Multiple-cursors 真的好爽!

重新设定了一下热键,变为SPC d开头,感觉好爽:

我是在evil的visual state才生效的快捷键,反正一般是在标记之后才会用这个 :grinning:

还有ace-mc,可以很方便的选择要产生光标的位置

一般用于什么场景下?

Emacs Rocks! Episode 08: mark-multiple

这里有介绍,虽然不是mc的,但是功能差不多。

Multiple-cursors 在标记了多个光标之后,没有没办法同时选中多个光标的内容(例如yw),并yank到kill ring当中。

multiple cursors和spacemacs配合的不大好,在issue里面有讨论的。

Multiple Cursors Integration Discussion

最近改用evil-mc了。spacemacs自带了这个,只要打开就可以用,但是对于某些操作(比如hungry-delete之类的)没法在多光标下执行,需要设置变量evil-mc-custom-known-commands。这是我的配置,额外增加了一个micro-state,这样在make光标的时候就不用一直按着ctrl了。只不过ace-mc没法用在evil-mc上,有些不爽。

(defun liu233w/post-init-evil-mc ()
  (add-hook 'prog-mode-hook 'evil-mc-mode)
  (add-hook 'text-mode-hook 'evil-mc-mode)

  ;; 设置在evil-mc之下可以执行的命令,主要是删除操作
  (setq evil-mc-custom-known-commands
        '((paredit-backward-delete . ((:default . evil-mc-execute-default-call-with-count)))
         (hungry-delete-backward . ((:default . evil-mc-execute-default-call-with-count)))
         (org-delete-backward-char . ((:default . evil-mc-execute-default-call-with-count)))
         ))

不错,抄你的配置试试。

多光标复制粘贴没问题(是我理解错了么?)

你用的是multi cursor,还是evil-mc

multiple-cursors + 原生 emacs

原生的emacs就不用说了,我是说Spacemacs+multiple-cursors不行。

我认为并没有什么差别,我同样是 evil-mode,进入到多光标模式下,就不要再拘泥 vi 的操作方式,切换到类似 hybrid-mode 方式,问题就解决了

上面elisp暂时看不大懂,不过貌似没人提到这个?: https://github.com/hlissner/evil-multiedit 在spacemacs自带的iedit基础上改的,支持sublime经典的渐进式选择的方式,我昨晚看day3的时候找到的,还没试不过从文档来看非常棒。

请问要如何启用和使用evil-mc? 虽然能在Spacemacs,但是在M-x中没有相关的选项。因为不知道使用时是怎样操作,所以也无法确认是不是已经开启了。

看看你想用的evil-mc-match之类的函数有没有加载咯。或者(featurep 'evil-mc)(evil-mc或者evil-mc-mode,看作者心情了)

hungry-delete 是做什么用的?

同样使用 evil-mc-mode 如果同时使用的 evil-collections 的话,按键不起作用了,有人遇到过吗?
