For options I change often, I use the following to
display its value in the statusline.
function! OptSet(opt, string)
if(exists("a:opt") && expand(a:opt))
return a:string
else
return ""
endif
endfunction
Then put the following in the statusline:
set statusline=%<%f\%h%m%r%y%{OptSet(&ic,'[ic]')}[...]
So in this specific case, if 'ic' is set, I will
have '[ic]' in my status line.
I use that for 'ic' and 'ws' because I toggle them
quite ofen.

Is there a way to do this? I wrote a plugin that toggles "invisible" characters with F4: http://vim.sourceforge.net/scripts/script.php?script_id=363 -- Steve Hall [ digitect dancingpaper com ]

Re: Question about listchars
Thanks for all the suggestions. They helped out... If there a way to check and see if the listchar is actually set or not? In my script, I now turn off the display with 'set invlist list?', but I do not want to turn it back on if it was not previously set... Well, you can use the common idiom let l:old_list = &list set nolist " do stuff let &list = l:old_list which will allow you to temporarily disable the 'list' setting, do stuff without it, and then restore it to whatever it was previously... -tim

check and see if the listchar is actually set or not?
In my script, I now turn off the display with 'set invlist list?', but
I do not want to turn it back on if it was not previously set...

Is there a way to do this? :map l :set invlist Then type \l when you want to toggle ( is \ by default). Change the binding however you like, but invfoo inverts the foo setting.

You can toggle back and forth with:
:se invlist
This can be placed in a map like this:
nm l :se invlist list?
where "invlist" will toggle the 'list' option and "list?"
will display the new state.
For help on ":se {option}?" and ":se inv{option}" see:
:h set-option

" This shows spaces and tabs characters. Visual Whitespace. set listchars=tab:»·,trail:· set list That all work well and good, but I would like to disable this display of visual white space temporarily, do something, and then reset it back to what I had. Is there a way to do this? Well, there are a number of possible solutions. The 'listchars' setting only allows for showing trailing whitespace. If this is what you're looking for, you can do something like set listchars+=trail:_ do your thing, and then set listchars-=trail:_ to undo it. If you want to visualize all your whitespace, you can do it with 1) search highlighting (to get cleared on your next search): :set hls /\s and then optionally reset with :set nohls or :noh 2) match highlighting (to optionally be used in complement to search highlighting): :match SpellBad /\s/ and then reset with :match NONE 3) or you can do it by substituting all of your white-space with some visual character: :%s/\s/#/g and then just undoing with "u" as usual. Just a few ideas... -tkc
