An attempt to port Kakoune's multiple selections into Emacs.

This package provides functions that simulate Kakoune's multiple selection commands. It's built on top of evil-mc's multiple cursors and evil's functions.

The package's main functions:

• | (Kakoune) - kak-exec-shell-command (command) (Emacs): execute a shell command using each cursor's region as the standard input and replace the region's content with the standard output.
• s/S (Kakoune) - kak-select (beg end invert) (Emacs): split/select a given region into multiple matching regions. invert determines whether the command should do a split (inver match).
• M-s (Kakoune) - kak-split-lines (beg end) (Emacs): split a given region into multiple lines. There will be a cursor each line.
• M-k/M-K (Kakoune) - kak-filter (keep) (Emacs): filter/keep all active cursors. keep determines whether the command should keep or remove the matching cursors.

• kak-insert-index (base) insert an index after each cursor based on a base index and the cursor's position relative to other cursors.

To install using Doom Emacs's package! macro:

(package! kak
  :recipe (:host github :repo "aome510/kak.el"))

To use the package after installation

(use-package kak)

An example mapping using Doom Emacs's map! macro:

(map!
  :v "|" #'kak-exec-shell-command
  :v "s" (lambda (beg end) (interactive "r") (kak-select beg end nil))
  :v "S" (lambda (beg end) (interactive "r") (kak-select beg end t))
  :v "M-s" #'kak-split-lines
  :v "M-k" (lambda () (interactive) (kak-filter t))
  :v "M-K" (lambda () (interactive) (kak-filter nil))
  :v ". #" #'kak-insert-index)
