[Feature Request] foldcolumn independent window

[juanMarinero]

behavior

When opening a vertical split (:vsplit) the foldcolumn setting from original window is set in the vertical split one.

Same happens with vim-peekaboo.

See next screenshots, in its command line I executed :set foldcolumn? just before pressing " in normal mode:

desired behavior

Either:

• vim-peekaboo window with :set foldcolumn=0
• or floating window for Vim: issue 68

Suggestions

• add modeline comment (to be hided by syntax that reads vim-peekaboo window)
• execute :set foldcolumn=0 in vim plugin just after create the vertical split
• customize the default plugin mapping (without modifying plugin code). My best failing try: nnoremap <silent> <F1> :<c-u>let foldcolumn_orig=&foldcolumn <bar> set foldcolumn=0 <bar> call peekaboo#aboo() <bar> exec 'set foldcolumn='.foldcolumn_orig <cr>

Desktop

Ubuntu 20.04
Vim 8.2

Thanks in advance!

See pull request 79 where at start of function! peekaboo#aboo() of vim-peekaboo/autoload/peekaboo.vim
I added

let g:foldcolumn_orig=&foldcolumn " at EO-func restore original
set foldcolumn=0  " so peekaboo vsplit has it too

and at end I appended

" restore with window foldcolumn
exec 'set foldcolumn='.g:foldcolumn_orig

But I think I would be clearer with a decorator, like:

nnoremap <leader>z <C-u>:call Peekaboo_aboo_Wrapper()<CR>
function! Peekaboo_aboo_Wrapper(...)
  " python wrapper decorator for Vim
  " ... read https://vim.fandom.com/wiki/Write_your_own_Vim_function
  
  " before call peekaboo#aboo
  let g:foldcolumn_orig=&foldcolumn
  set foldcolumn=0  " so peekaboo vsplit has it too

  " wrapped function
  let params = [] " not empty, minimun required: list
  :call call (function('peekaboo#aboo'), params)

  " after call peekaboo#aboo
  " wincmd p  " move-cursor-back-to-previous-window-after-splitting
  exec 'set foldcolumn='.g:foldcolumn_orig
endfunction
