use matchpairs for g:targets_argClosing/Opening

[Konfekt]

How about using matchpairs to set g:targets_argClosing/Opening by default ? That could be achieved by

let g:targets_argOpening = '['
let g:targets_argClosing = '['

let mps = split(&g:matchpairs, ',')
for mp in mps
  let mpOC = split(mp, ':')
  let g:targets_argOpening = g:targets_argOpening . mpOC[0]
  let g:targets_argClosing = g:targets_argClosing . mpOC[1]
endfor
unlet mps
unlet mp
unlet mpOC

let g:targets_argOpening = g:targets_argOpening . ']'
let g:targets_argClosing = g:targets_argClosing . ']'

The comparison with &g:matchpairs also suggests a buffer local version b:targets_argClosing/Opening.

That's an interesting idea.

But it would change the current default to include curly braces. Also I believe the closing ] needs to be escaped inside [] unless it's the first character (that's why I put it like this).

There might be good reasons to differ from setglobal matchpairs& but as a dilettante I see none.

True that ] must be escaped. Another reason to prefer the syntax of matchpairs ? Again, as an outsider, the enclosing [ ] do not seem necessary.

My bad, now I understand that [..] is a regex. Still, perhaps the regex could by default coincide with that given by&g:matchpairs.

Here is an updated version of the above script converting &matchpairs into an opening and closing regex pattern as expected by g:targets_argOpening/Closing:

let g:targets_argOpening = '['
let g:targets_argClosing = '['

let mps = split(&g:matchpairs, ',')
for mp in mps
  let mpOC = split(mp, ':')
  let g:targets_argOpening = g:targets_argOpening . escape(mpOC[0], ']^-\')
  let g:targets_argClosing = g:targets_argClosing . escape(mpOC[1], ']^-\')
endfor
unlet mps
unlet mp
unlet mpOC

let g:targets_argOpening = g:targets_argOpening . ']'
let g:targets_argClosing = g:targets_argClosing . ']'
