Re: loss of tags

     Why not either

let s:taglist = taglist()

to save the tags before switching windows or

wincmd p

" Do something with taglist()

wincmd p

so that you return to the right window before issuing the taglist() command.

     Variants:  s:taglist could be a Dictionary, keyed on the buffer name or number.  If you save the buffer number, then you can switch to the right buffer even if there are more window-switching commands than you have told us about.

     IWBNI taglist() accepted an optional buffer identifier.

Hello!

I'm putting together a script that

  * reads a log file which contains procedure names and line numbers
  * uses taglist() to obtain a filename associated with a procedure name

The relevant script:

      exe s:prcwin."wincmd w"
     " an echomsg shows that taglist() can obtain a filename associated with a procedure name here
      exe "sil! e! ".fnameescape(proc["filename"])
     " an echomsg here shows that taglist() comes up empty

So, clearly the editing of a file causes a loss of the tags.  (btw, I used the same filename in both echomsg s)

 * how can I prevent that loss of tags from occurring?
 * or how can I get vim to re-read that tags file?

Thanks!
