- Increment / Decrement binary, octal, decimal and hex literals.
- Works like
C-a
/C-x
in VIM, i.e. searches for number up toeol
and then increments or decrements. - When a region is active, as in evil’s visual mode, all the numbers within that region will be incremented/decremented (unlike in VIM).
- Increment/decrement numbers incrementally like
g C-a
/g C-x
in VIM. - Optionally keep zero padding (off by default).
- Binary, e.g.
0b0101
,0B0101
. - Octal, e.g.
0o755
,0O700
. - Hexadecimal, e.g.
0xDEADBEEF
,0XCAFE
. - Unicode superscript and subscript, e.g.
²
and₁
.
Once this package is installed, all you need to do is bind keys to
evil-numbers/inc-at-pt
and evil-numbers/dec-at-pt
.
Position cursor over or before the literal and play with your numbers!
You may also want to bind keys to the incremental versions of these functions.
evil-numbers-pad-default
-
Set to
t
if you want numbers to be padded with zeros (numbers with a leading zero are always padded). If you want both behaviors, all commands take an optional argumentpadded
. evil-numbers-separator-chars
-
This option to support separator characters, set to “_” or “,” to support numeric literals such as:
16_777_216
or4,294,967,296
.You may wish to set this as a buffer local variable to enable this only for languages that support separators.
evil-numbers-case
-
The case to use for hexadecimal numbers.
nil
Current case (default).- ‘
upcase
Always upper case. - ‘
downcase
Always lower case.
evil-numbers-use-cursor-at-end-of-number
-
Support matching numbers directly before the cursor.
This is off by default as it doesn’t follow VIM’s behavior.
Example key bindings:
(global-set-key (kbd "C-c +") 'evil-numbers/inc-at-pt)
(global-set-key (kbd "C-c -") 'evil-numbers/dec-at-pt)
(global-set-key (kbd "C-c C-+") 'evil-numbers/inc-at-pt-incremental)
(global-set-key (kbd "C-c C--") 'evil-numbers/dec-at-pt-incremental)
or only in evil’s normal
& visual
states:
(evil-define-key '(normal visual) 'global (kbd "C-c +") 'evil-numbers/inc-at-pt)
(evil-define-key '(normal visual) 'global (kbd "C-c -") 'evil-numbers/dec-at-pt)
(evil-define-key '(normal visual) 'global (kbd "C-c C-+") 'evil-numbers/inc-at-pt-incremental)
(evil-define-key '(normal visual) 'global (kbd "C-c C--") 'evil-numbers/dec-at-pt-incremental)
Keypad +
and -
present an alternative that can be directly bound without shadowing the regular +
and -
:
(evil-define-key '(normal visual) 'global (kbd "<kp-add>") 'evil-numbers/inc-at-pt)
(evil-define-key '(normal visual) 'global (kbd "<kp-subtract>") 'evil-numbers/dec-at-pt)
(evil-define-key '(normal visual) 'global (kbd "C-<kp-add>") 'evil-numbers/inc-at-pt-incremental)
(evil-define-key '(normal visual) 'global (kbd "C-<kp-subtract>") 'evil-numbers/dec-at-pt-incremental)
Put in load-path
, (require 'evil-numbers)
and set key bindings.
Assuming you have the melpa
repository enabled, use-package
can be used as follows.
(use-package evil-numbers)
