How to refresh taglist in vim?

Question

When I make a change to a file, for example, add a function, how can I make the taglist automatically update the \"tag list\" in its windows after I save the change?

Answer 1

I did write a little experimental script that automatically and incrementally updates, the "current" tags file on file saving.

(The question is actually redundant with Vim auto-generate ctags )

Answer 2

Haven't tested, but you could try something like:

au BufWritePre     *.cpp ks|!ctags %

Which basically executes ctags when the buffer for a file ending in .cpp gets saved(:w).

Answer 3

I adapted my setup from the C++ code completion vim tip.

map <C-F12> :!ctags -R --c++-kinds=+p --fields=+iaS --extra=+q .<CR>

When needed, I press Ctrl-F12 to regenerate tags.

If you're using vim-taglist, you could add to your .vimrc an autocommand for the BufWritePost event to update the taglist window after every save:

autocmd BufWritePost *.cpp :TlistUpdate

Just add this to your ~/.vimrc

function! DelTagOfFile(file)
  let fullpath = a:file
  let cwd = getcwd()
  let tagfilename = cwd . "/tags"
  let f = substitute(fullpath, cwd . "/", "", "")
  let f = escape(f, './')
  let cmd = 'sed -i "/' . f . '/d" "' . tagfilename . '"'
  let resp = system(cmd)
endfunction

function! UpdateTags()
  let f = expand("%:p")
  let cwd = getcwd()
  let tagfilename = cwd . "/tags"
  let cmd = 'ctags -a -f ' . tagfilename . ' --c++-kinds=+p --fields=+iaS --extra=+q ' . '"' . f . '"'
  call DelTagOfFile(f)
  let resp = system(cmd)
endfunction
autocmd BufWritePost *.cpp,*.h,*.c call UpdateTags()
