Some plugins inadvertently set global options. I have the following code at the top of my vimrc, and set all options to my preferred values using the SetOption
command. Whenever I want to reset options I do :ResetOptions
which resets all user-defined options previously set by SetOption
.
let s:option_preferences = [] function! ResetOption(options) if empty(a:options) let options = s:option_preferences else let options = a:options endif for name in options let name0 = 'g:'. name .'_default' if exists(name0) exec 'let &'. name .' = '. name0 endif endfor endfunction command! -nargs=* ResetOption :call ResetOption([<f-args>]) command! -nargs=+ SetOption let s:tmlargs=[<f-args>] \ | for arg in s:tmlargs[1:-1] \ | if arg =~ '^[+-]\?=' \ | exec 'set '.s:tmlargs[0] . arg \ | else \ | exec 'let &'.s:tmlargs[0] .'='. arg \ | endif \ | endfor \ | call add(s:option_preferences, s:tmlargs[0]) \ | exec 'let g:'. s:tmlargs[0] .'_default = &'. s:tmlargs[0] \ | unlet s:tmlargs
Examples[]
Add and remove specific options
:SetOption cpo +=my -=M
Set the value
:SetOption ts 4 :SetOption ts =4
Just cache the predefined value so that it can be restored later
In this example a later reset would be the same as :set tw&
:SetOption tw
Reset specific options
:ResetOption ts tw
Reset all user-set options
:ResetOption
In order to monitor the options setting, I display changed values in &statusline
.
set statusline=%1*[%{winnr()}:%02n]%*\ %2t\ %(%M%R%H%W%k%)\ %=%{TmlStatusline()}\ %3*<%l,%c%V,%p%%>%* function! TmlStatusline() let opt = "<". &syntax ."/". &fileformat .">" if !&backup | let opt=opt." no-bak" |endif if !&et | let opt=opt." no-et" |endif if &list | let opt=opt." list" |endif if &paste | let opt=opt." paste" | endif if !&expandtab | let opt=opt." tab" | endif if &ts != g:ts_default | let opt=opt.' ts='.&ts | endif if &sw != g:sw_default | let opt=opt.' sw='.&sw | endif if &tw != g:tw_default | let opt=opt.' tw='.&tw | endif if &wm != g:wm_default | let opt=opt.' wm='.&wm | endif if &enc != g:enc_default | let opt=opt.' enc='.&enc | endif if &ve != g:ve_default | let opt=opt.' ve='. &ve | endif if &fo != g:fo_default | let opt=opt.' fo='. &fo | endif if &cpo != g:cpo_default | let opt=opt.' cpo='. &cpo | endif if &bin | let opt=opt.' [bin]' | endif if &foldlevel != s:foldlevel | let opt=opt.' F'.&foldlevel | endif let opt=opt." | ".strftime("%d-%b-%Y %H:%M") return opt endfunction

Here is a slightly modified version:
let s:options = {} function! ResetOption(options) if empty(a:options) let options = keys(s:options) else let options = a:options endif for name in options exec 'let &'. name .' = s:options[name]' endfor endfunction command! -nargs=* ResetOption :call ResetOption([<f-args>]) command! -nargs=+ SetOption let s:tmlargs=[<f-args>] \ | for arg in s:tmlargs[1:-1] \ | if arg =~ '^[+-]\?=' \ | exec 'set '.s:tmlargs[0] . arg \ | else \ | exec 'let &'.s:tmlargs[0] .'='. arg \ | endif \ | endfor \ | exec 'let s:options[s:tmlargs[0]] = &'. s:tmlargs[0] \ | unlet s:tmlargs let s:option_labels = {'fdl': 'F'} function! TmlStatusline() let opt = "<". &syntax ."/". &fileformat .">" if !&backup | let opt=opt." no-bak" |endif if !&et | let opt=opt." no-et" |endif if &list | let opt=opt." list" |endif if &paste | let opt=opt." paste" | endif if !&expandtab | let opt=opt." tab" | endif for [o, v] in items(s:options) exec 'let oo = &'.o if oo != v let opt .= ' '. (has_key(s:option_labels, o) ? s:option_labels[o] : o.'=') . oo endif endfor if &bin | let opt=opt.' [bin]' | endif if exists('b:compressed') | let opt=opt.' ['.b:compressed.']' | endif let opt=opt." | ".strftime("%d-%b-%Y %H:%M") return opt endfunction
