update tag information. This should be called after you have used
|tagbar#currenttag| manually.
*tagbar#GetTagNearLine()*
Get the current tag near the specified line number (lnum). Optionally
takes a fmt and signature specification using the same method as the
|tagbar#currenttag()| function. Defaults to GetTagNearLine(lnum, '%s', '').
This could be used in a custom foldtext function to show the current tag
the fold current fold is located in.
Example:
>
set foldtext=MyFoldFunc()
function! MyFoldFunc()
let tag = tagbar#GetTagNearLine(v:foldend, '%s', 'p')
let lines = v:foldend - v:foldstart + 1
return tag . ' --- ' . lines . ' lines'
endfunction
