Duplicate tip
This tip is very similar to the following:
These tips need to be merged – see the merge guidelines.
Here's a little function I put together to make some of my mappings easier to read, understand and change.
function ToggleFlag(option,flag)
exec ('let lopt = &' . a:option)
if lopt =~ (".*" . a:flag . ".*")
exec ('set ' . a:option . '-=' . a:flag)
else
exec ('set ' . a:option . '+=' . a:flag)
endif
endfunction
Examples of use:
map <silent> <F8> :call ToggleFlag("guioptions","m")<CR>
map <silent> <F9> :call ToggleFlag("guioptions","T")<CR>
The following might be more flexible (I think it should work for any flag-style option).
" my function to cycle a numeric option
function CycleNum(option,min,inc,max)
exec ('let tz_value = (((&'.a:option.'-'.a:min.')+'.a:inc.')%(('.a:max.'-'.a:min.')+'.a:inc.'))+'.a:min)
if (tz_value < a:min) " in case inc<0
let tz_value = tz_value+a:max
endif
exec ('setlocal '.a:option.'='.tz_value)
endfunction
" my function to toggle an option flag
function ToggleFlag(option,flag)
exec ('let tf_o = &'.a:option)
exec ('setlocal '.a:option.'-='.a:flag)
exec ('let tf_t = &'.a:option)
if (tf_o == tf_t)
exec ('setlocal '.a:option.'+='.a:flag)
endif
endfunction
