Full description

1. Features

  • Increment / Decrement binary, octal, decimal and hex literals.
  • Works like C-a / C-x in VIM, i.e. searches for number up to eol 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).

1.1. Detected Literals

  • Binary, e.g. 0b0101, 0B0101.
  • Octal, e.g. 0o755, 0O700.
  • Hexadecimal, e.g. 0xDEADBEEF, 0XCAFE.
  • Unicode superscript and subscript, e.g. ² and ₁.

2. Usage

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.

2.1. Customization

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 argument padded.
evil-numbers-separator-chars

This option to support separator characters, set to "_" or "," to support numeric literals such as: 16_777_216 or 4,294,967,296.

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.

2.2. Key Bindings

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)

3. Install

3.1. Basic Installation

Put in load-path, (require 'evil-numbers) and set key bindings.

3.2. Use Package

Assuming you have the melpa repository enabled, use-package can be used as follows. 

(use-package evil-numbers)

News

1. 0.7

1.1. Additions

  • evil-numbers-use-cursor-at-end-of-number option to match numbers directly before the cursor (diverging from VIM's default behavior).

1.2. Changes

  • Use message instead of error when no number is found (don't error since VIM doesn't use an error in this case).

1.3. Fixes

  • Fix #27 Number directly before the cursor manipulated when the cursor can't move forward.

2. 0.6

2.1. Additions

  • Add evil-numbers-separator-chars option to support separator characters, such as 16_777_216 or 4,294,967,296.
  • Add evil-numbers-case option for the case to use for hexadecimal values (defaults to the current case).

2.2. Fixes

  • Fix #25 increment steps to the next line.
  • Fix #24 hexadecimal values case changes when incrementing/decrementing.
  • Fix padding being ignored with block selection.
  • Fix #21 increment w/ selection ignores items before the cursor.
  • Fix padded argument is ignored on non-decimal types.
  • Fix #20 The cursor moves when increment/decrement fails.
  • Fix #18 operating on bin/hex/octal failed w/ the cursor at the start.
  • Fix #17 bin/octal/hex numbers don't support becoming negative.
  • Fix hyphen-separated numbers handling.
  • Fix auto-loading evil macros.

3. 0.5

3.1. Additions

  • Make padding optional.
  • Add support for block selections.
  • Add support for subscript and superscript numbers.
  • Add g C-a like functionality (i.e. increment first number in selection by 1, second one by 2 and so on).
  • Pad negative numbers and add a plus sign if a negative number is turned into a positive number (if padding is enabled).

3.2. Fixes

  • Fix numbers being pushed out of selections.

    (e.g. calling inc-at-pt on ^9 9$ where ^$ denote the start and end of the selection would result in 10 9).
