Customization

See :help textobj-numeral

Change matching patterns

The pattern for the each text objects is defined by some variables. You can modify the regular expressions to suit your specific needs. For example, changing id behavior, please add the following code.

let g:textobj_numeral_digit_i_pattern = '[1-9]\d*'          " Default:'\d\+'

Disable default key mappings

If you need to change or disable the default keymappings, please define g:textobj_numeral_no_default_key_mappings, and redefine vmap and omap.

let g:textobj_numeral_no_default_key_mappings = 1

vmap an	<Plug>(textobj-numeral-a)
omap an	<Plug>(textobj-numeral-a)
vmap in	<Plug>(textobj-numeral-i)
omap in	<Plug>(textobj-numeral-i)

vmap ad	<Plug>(textobj-numeral-digit-a)
omap ad	<Plug>(textobj-numeral-digit-a)
vmap id	<Plug>(textobj-numeral-digit-i)
omap id	<Plug>(textobj-numeral-digit-i)

Application

There is a useful application to input sequential numbers. Write the following code in your .vimrc

set nrformats-=octal

function! Increment(motion, step)
    let inc_key = a:step > 0 ? "\<C-a>" : "\<C-x>"
    let @z = '"zyad' . a:motion . 'vad"zp'. abs(a:step) . inc_key
    return '@z'
endfunction

nmap <expr> + Increment('j', 1)
nmap <expr> - Increment('j', -1)
nmap <expr> ) Increment('gNd', 1)
nmap <expr> ( Increment('gNd', -1)

Move cursor to the top of '00', and type ++++++++++ or 10+

	aaa00ccc	->	aaa00ccc
	aaa00ccc	->	aaa01ccc
	aaa00ccc	->	aaa02ccc
	aaa00ccc	->	aaa03ccc
	aaa00ccc	->	aaa04ccc
	aaa00ccc	->	aaa05ccc
	aaa00ccc	->	aaa06ccc
	aaa00ccc	->	aaa07ccc
	aaa00ccc	->	aaa08ccc
	aaa00ccc	->	aaa09ccc
	aaa00ccc	->	aaa10ccc

Move cursor to the first '0', and type ) or 10)

	[0,0,0,0,0,0,0,0,0,0,0]   ->   [0,1,2,3,4,5,6,7,8,9,10]
