Vim 9 implementation of matchparen.vim

[Christian J. Robinson]

I've attached a Vim 9 implementation of the matchparen.vim plugin.

There was a fair amount of logic to determine whether features existed, but since this is a Vim 9 implementation it is safe to assume those features will exist so that logic was removed.

If there's interest I am willing to do similar work on other distribution scripts.

Somehow I missed a couple of bugs, so I've attached a fixed version.

Thank you for doing this. I hope several people try it out and let us
know how well it works. If everybody is happy I can include it in the
distribution.

I've attached another bugfix version.

I was wondering if there was any particular reason that in the middle of the matchparen script,

an eval is used as the if condition instead of just running the code directly.

    s_skip = '!empty(filter(map(synstack(line("."), col(".")), ''synIDattr(v:val, "name")''), ' ..
      '''v:val =~? "string\\|character\\|singlequote\\|escape\\|symbol\\|comment"''))'
    # If executing the expression determines that the cursor is currently in...
    try
      if eval(s_skip)
        s_skip = "0"
      endif
    catch /^Vim\%((\a\+)\)\=:E363/
      # We won't find anything, so skip searching, should keep Vim responsive.
      return
    endtry

I was trying to understand why that couldn't just be executed directly in the if condition.

Thanks,

TJ
