** Multiple cursors implementation for evil-mode *** Synopsis evil-mc provides multiple cursors functionality for Emacs when used with evil-mode *** Usage Start with: #+BEGIN_SRC emacs-lisp (require 'evil-mc) #+END_SRC **** Local Setup To enable or disable evil-mc mode for a single buffer use:\ #+BEGIN_SRC emacs-lisp (evil-mc-mode 1) ;; enable (evil-mc-mode -1) ;; disable #+END_SRC **** Global Setup To enable or disable evil-mc mode for all buffers use:\ #+BEGIN_SRC emacs-lisp (global-evil-mc-mode 1) ;; enable (global-evil-mc-mode -1) ;; disable #+END_SRC **** Basic Usage The main commands used to create or delete cursors are:

#+BEGIN_SRC emacs-lisp (evil-mc-make-all-cursors) ;; Create cursors for all strings that match the selected ;; region or the symbol under cursor.

(evil-mc-undo-all-cursors) ;; Remove all cursors.

(evil-mc-make-and-goto-next-match) ;; Make a cursor at point and go to the next match of the ;; selected region or the symbol under cursor.

(evil-mc-skip-and-goto-next-match) ;; Go to the next match of the selected region or the symbol under ;; cursor without creating a cursor at point. #+END_SRC

The above commands as well as others, detailed below, are setup with key bindings when the evil-mc mode is enabled. The keys are defined in evil-mc-key-map. You can take a look at that variable declaration in [[https://github.com/gabesoft/evil-mc/blob/master/evil-mc.el][evil-mc.el]] to see all key bindings. But, in short, C-n / C-p are used for creating cursors, and M-n / M-p are used for cycling through cursors. The commands that create cursors wrap around; but, the ones that cycle them do not. To skip creating a cursor forward use C-t or grn and backward grp. Finally use gru to "undo" the last added cursor, and grq to remove all cursors.

Optionally set up visual mode keybindings for I and A to create cursors at the beginning or end of every visually selected line.

#+BEGIN_SRC emacs-lisp (evil-define-key 'visual evil-mc-key-map "A" #'evil-mc-make-cursor-in-visual-selection-end "I" #'evil-mc-make-cursor-in-visual-selection-beg) #+END_SRC

For an example of setting up evil-mc see this [[https://github.com/gabesoft/evil-mc/blob/master/evil-mc-setup.el][setup file]] **** Commands Here's a detailed list of all commands used to create, navigate through, or delete cursors:\ /All the commands below assume that there is a real cursor and possibly some fake cursors./

#+BEGIN_SRC emacs-lisp (evil-mc-make-all-cursors) ;; Make a cursor for every match of the selected region or the symbol at point.

(evil-mc-undo-all-cursors) ;; Remove all cursors.

(evil-mc-undo-last-added-cursor) ;; Remove the last added cursor and move point to its position.

(evil-mc-make-and-goto-next-match) ;; Make a cursor at point, and go to the next match of the ;; selected region or the symbol at point.

(evil-mc-make-and-goto-prev-match) ;; Make a cursor at point, and go to the previous match of the ;; selected region or the symbol at point.

(evil-mc-skip-and-goto-next-match) ;; Go to the next match of the selected region or symbol at point ;; without making a cursor at point. This command can be used to ;; remove unwanted cursors.

(evil-mc-skip-and-goto-prev-match) ;; Go to the previous match of the selected region or symbol at point ;; without making a cursor at point. This command can be used to ;; remove unwanted cursors.

(evil-mc-make-and-goto-prev-cursor) ;; Make a cursor at point and move point to the cursor ;; closest to it when searching backwards.

(evil-mc-make-and-goto-next-cursor) ;; Make a cursor at point and move point to the cursor ;; closest to it when searching forwards.

(evil-mc-skip-and-goto-prev-cursor) ;; Move point to the cursor closest to it when searching backwards ;; without making a cursor at point. This command can be used to ;; remove unwanted cursors.

(evil-mc-skip-and-goto-next-cursor) ;; Move point to the cursor closest to it when searching forwards ;; without making a cursor at point. This command can be used to ;; remove unwanted cursors.

(evil-mc-make-and-goto-first-cursor) ;; Make a cursor at point and move point to the cursor at the first position.

(evil-mc-make-and-goto-last-cursor) ;; Make a cursor at point and move point to the cursor at the last position.

(evil-mc-make-cursor-here) ;; Create a cursor at point. This command should be used with `evil-mc-pause-cursors'.

(evil-mc-pause-cursors) ;; Pause all fake cursors. This can be used with `evil-mc-make-cursor-here'

(evil-mc-resume-cursors) ;; Call to resume paused cursors.

(evil-mc-make-cursor-in-visual-selection-beg) ;; Create cursors at the beginning of every visually selected line.

(evil-mc-make-cursor-in-visual-selection-end) ;; Create cursors at the end of every visually selected line. #+END_SRC

**** Customization evil-mc can be customized in several ways:

  • Every known command is executed using a command handler defined in a variable called evil-mc-known-commands in [[https://github.com/gabesoft/evil-mc/blob/master/evil-mc-known-commands.el][evil-mc-known-commands.el]]. Those can be overridden by defining the evil-mc-custom-known-commands variable. See the documentation of that variable in [[https://github.com/gabesoft/evil-mc/blob/master/evil-mc.el][evil-mc.el]] for more info.

  • Some minor modes are incompatible with evil-mc. Those modes are defined in evil-mc-incompatible-minor-modes and can be overridden by defining that variable.

  • In addition there are two hooks that can be used to temporarily disable or enable additional functionality while there are multiple cursors active #+BEGIN_SRC emacs-lisp evil-mc-before-cursors-created ;; this hook runs just before the first cursor is created

    evil-mc-after-cursors-created ;; this hook runs just after the last cursor is deleted #+END_SRC

*** Mode line text and colors There are 4 variables, that can change the mode lines text, and its color.

**** Only one cursor The emc text can be hidden, by setting this variable to nil. (default: t) #+BEGIN_SRC (setq evil-mc-one-cursor-show-mode-line-text t) #+END_SRC

**** Two or more cursors, resumed (unpaused) The resumed mode line text, can have two different colors:

  • The cursors color, when this variable is t.
  • The default colors, when this variable is nil. (default: t) #+BEGIN_SRC (setq evil-mc-mode-line-text-cursor-color t) #+END_SRC

**** Two or more cursors, paused The (paused) text can be hidden, by setting this variable to nil. (default: t) #+BEGIN_SRC (setq evil-mc-mode-line-text-paused t) #+END_SRC

The paused mode line text can have three different colors:

  • Inverse colors, when the inverse colors variable is t.
  • Cursors color, when the inverse colors variable is nil, and the cursor color variable is t.
  • Default colors, when both the inverse and cursor color variables are nil. (default: t, for both the inverse and cursor variables) #+BEGIN_SRC (setq evil-mc-mode-line-text-inverse-colors t) (setq evil-mc-mode-line-text-cursor-color t) #+END_SRC

*** Notes

  • Most evil motions and operators are supported but not every single command will work.
  • If the cursors don't seem to work during a command, either the command is not known (see evil-mc-known-commands in [[https://github.com/gabesoft/evil-mc/blob/master/evil-mc-known-commands.el][evil-mc-known-commands.el]]) or some minor modes could be interfering with the evil-mc operations.
  • Issues and pull requests are welcome.

**** Debugging

  • When a command does not work, and you want to get more information, you can enable (or disable) debugging by running any of the commands below interactively. #+BEGIN_SRC emacs-lisp (evil-mc-executing-debug-on) ;; Turn debug on while executing a command.

    (evil-mc-executing-debug-off) ;; Turn debug off while executing a command.

    (evil-mc-recording-debug-on) ;; Turn debug on while recording a command.

    (evil-mc-recording-debug-off) ;; Turn debug off while recording a command.

    (evil-mc-all-debug-on) ;; Turn all debug on.

    (evil-mc-all-debug-off) ;; Turn all debug off. #+END_SRC

**** Limitations

  • After an undo command the cursors will return to their original positions if [[http://www.emacswiki.org/emacs/UndoTree][undo-tree]] mode is enabled and evil-repeat has not been used.
  • Redo may cause the real cursor to get out of sync with the others. This can be worked around by setting a mark and returning to it after a redo.
  • Jumps work if [[https://github.com/bling/evil-jumper][evil-jumper]] mode is enabled
  • Search commands such as evil-search-forward, evil-search-backward, and evil-search-next are not supported

**** Known issues

  • Only named commands can be executed by the fake cursors.
  • There could be a performance penalty when there are too many cursors (30+).
  • Paste will not work when [[https://github.com/syl20bnr/spacemacs][spacemacs]]' paste micro state is enabled. This is due to the fact that evil-paste-pop and evil-paste-pop-next commands are not supported.
  • evil-repeat works only for some commands. In particular it doesn't work for delete. It will also interfere with the cursor positions during an undo or redo operation.
