Oh, good call.
New implementation, still untested:
nnoremap! <Ctrl-]> :call <SID>SmartTagSearch()<CR>
let g:last_tag_file = [];
function! s:SmartTagSearch()
" get the first tag hit for the word under the cursor
let searchstr = expand("<cword>")
let firsttag = taglist(searchstr)[0]
" save off the current file in case we need it again
call add(g:last_tag_file, expand("%:p"))
" jump to the file containing the tag (in existing window
if possible)
execute 'drop' fnameescape(firsttag.filename)
" jump to the tag itself
execute 'tag' searchstr
endfunction
nnoremap! <Ctrl-T> :call <SID>SmartTagReturn()<CR>
function! s:SmartTagReturn()
if (empty(g:last_tag_file))
return
endif
" jump to the file containing the pre-tag position (in
existing window if possible)
execute 'drop' remove(g:last_tag_file, -1)
" jump to the pre-tag position itself
pop
endfunction
Note these will need an update, to handle a count. Currently they do
not handle a count correctly. In fact, they will fail entirely with a
count due to the auto-insertion of the count when you press (or map) :
in normal mode.
:he v:count and :he v:count1 should be of interest for this.
