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 ++++++++++
