Actualmente, mi Vim resalta paréntesis, corchetes, comillas, etc. coincidentes con el fondo cian y el primer plano blanco; el cursor se puede mover entre ellos con %. Gracias a mi matchit.vim, también puedo cambiar %entre if / end, for / end, etc., sin embargo, estos no están resaltados en la selección.
¿Cómo puedo resaltar automáticamente estos pares coincidentes tras la selección, como se hace automáticamente con paréntesis?
Además, ¿cómo puedo modificar el color de fondo utilizado para estos pares :highlight?
Gracias por adelantado.
He actualizado la respuesta de @Tommy A a continuación para tener en cuenta los matchit.vimgrupos mal especificados y otras situaciones en las %que el operador no regresa el cursor a la posición original. Vea las diferencias en el ciclo "while". Se recomienda a cualquiera que lea este hilo que use esta versión para evitar bucles infinitos:
function! s:get_match_lines(line) abort
" Loop until `%` returns the original line number; abort if
" (1) the % operator keeps us on the same line, or
" (2) the % operator doesn't return us to the same line after some nubmer of jumps
let a:tolerance=25
let a:badbreak=1
let a:linebefore=-1
let lines = []
while a:tolerance && a:linebefore != line('.')
let a:linebefore=line('.')
let a:tolerance-=1
normal %
if line('.') == a:line
" Note that the current line number is never added to the `lines`
" list. a:line is the input argument 'line'; a is the FUNCTION BUFFER
let a:badbreak=0
break
endif
call add(lines, line('.'))
endwhile
"Return to original line no matter what, return list of lines to highlight
execute "normal ".a:line."gg"
if a:badbreak==1
return []
else
return lines
endif
endfunction
function! s:hl_matching_lines() abort
" `b:hl_last_line` prevents running the script again while the cursor is
" moved on the same line. Otherwise, the cursor won't move if the current
" line has matching pairs of something.
if exists('b:hl_last_line') && b:hl_last_line == line('.')
return
endif
let b:hl_last_line = line('.')
" Save the window's state.
let view = winsaveview()
" Delete a previous match highlight. `12345` is used for the match ID.
" It can be anything as long as it's unique.
silent! call matchdelete(12345)
" Try to get matching lines from the current cursor position.
let lines = s:get_match_lines(view.lnum)
if empty(lines)
" It's possible that the line has another matching line, but can't be
" matched at the current column. Move the cursor to column 1 to try
" one more time.
call cursor(view.lnum, 1)
let lines = s:get_match_lines(view.lnum)
endif
if len(lines)
" Since the current line is not in the `lines` list, only the other
" lines are highlighted. If you want to highlight the current line as
" well:
" call add(lines, view.lnum)
if exists('*matchaddpos')
" If matchaddpos() is availble, use it to highlight the lines since it's
" faster than using a pattern in matchadd().
call matchaddpos('MatchLine', lines, 0, 12345)
else

" highlight group is used.

unlet! b:hl_last_line
endfunction
