I have some configuration in my .vimrc governing the initial folding strategy. Sometimes, I am looking to restore the initial state and would like a :refold command or something, which restores the initial state.
Is there some built-in way to do this?
would like a :refold command`
command! -range -addr=windows Refold call ResetWinOpts(<line1>, <line2>, ['fdm', 'fdl', ...])
command! RefoldAll tabdo %Refold
" reset options through a window-range to global values
function! ResetWinOpts(winid1, winid2, opts)
call execute(printf("%s,%swindo setl %s<", a:winid1, a:winid2, join(a:opts, "< ")))
endfunction
If you're only interested in undoing all effects of manual folding, like za/zo/zc etc. then, as @ChristianBrabandt suggested in the comments, the command zX will do this for you.
:e!do what you want?:enew | e#. But I doubt it should be recommended.:e!has always reset the folds for me. not sure why you would recommend opening the same file in a different window so.zaand other such commands which influence only individual folds, but not any of the window folding options. But if you ever usezR, or something like that, then its effect of setting localfoldlevelwill remain after:e!zXmight be helpful.
