Evil align operator

evil-lion

This package provides gl and gL align operators: gl MOTION CHAR and right-align gL MOTION CHAR.

Use CHAR / to enter regular expression if a single character wouldn't suffice.

Use CHAR RET to align with align.el's default rules for the active major mode.

Port of vim-lion

Installation

with use-package

(use-package evil-lion
  :ensure t
  :config
  (evil-lion-mode))

without use-package

M-x package-install RET evil-lion RET, then add in init.el:

(evil-lion-mode)

Usage

Align with gl MOTION CHAR or right-align with gL MOTION CHAR.

If the align separator is / you will be prompted for a regular expression instead of a plain character. If the align separator is RET alignment will be performed with align.el's rules specific for the major mode.

You can pass count 1 to align on the first occurrence of CHAR. To pass count, use: COUNT gl MOTION CHAR.

Example, left align gl:

After pressing glip= (gl is the operator, ip text object paragraph, = separator)

one = 1
three = 3
fifteen = 15

will become:

one     = 1
three   = 3
fifteen = 15

Example, right align with gL:

After pressing gLip,

one, two, three,
fifteen, sixteen, seventeen

will become:

one,     two,     three,
fifteen, sixteen, seventeen

Example, align with major mode's alignment rules:

In perl-mode, after pressing glib RET (RET is return key, not individal keys):

my %hash = (
   a => 1,
   bbb => 2,
   cccc => 3,

   a => 1,
   bbb => 2,
   cccccc => 3
);

will become:

my $hash = (
   a    => 1,
   bbb  => 2,
   cccc => 3,

   a      => 1,
   bbb    => 2,
   cccccc => 3
););

Example, align on the first occurrence of CHAR:

After pressing 1glip"

(red "red"
(teal-green "#6fb593")
(wheat "#b9c791")
(blue "blue")
(cyan "#54b6b6")

will become:

(red        "red"
(teal-green "#6fb593")
(wheat      "#b9c791")
(blue       "blue")
(cyan       "#54b6b6")

Customization

Disable squeezing of spaces

By default, evil-lion will remove unnecessary spaces if there are any. To disable this behaviour:

(setq evil-lion-squeeze-spaces nil) ;; default t

Change the default keys

;; use `g a` (mnemonic `align`)
;; these variables should be changed before (evil-lion-mode) is called
(setq evil-lion-left-align-key (kbd "g a"))
(setq evil-lion-right-align-key (kbd "g A"))
(evil-lion-mode)

Or withuse-package and bind-key:

(use-package evil-lion
  :ensure t
  :bind (:map evil-normal-state-map
         ("g l " . evil-lion-left)
         ("g L " . evil-lion-right)
         :map evil-visual-state-map
         ("g l " . evil-lion-left)
         ("g L " . evil-lion-right)))

Bind in prog modes only

Bind evil-lion-left and evil-lion-right to your liking. The evil-lion-mode is just a convenience mode and should not be enalbed with this setup.

(evil-define-key 'normal prog-mode-map
  (kbd "g l") 'evil-lion-left
  (kbd "g L") 'evil-lion-right)

(evil-define-key 'visual prog-mode-map
  (kbd "g l") 'evil-lion-left
  (kbd "g L") 'evil-lion-right)
