:TagFiles cmd in Drew Neil Ctags Episode

In the Drew Neil video on navigation via Ctags he makes mention of a custom :TagFiles command that helps you see which tag files are loaded. It’s not listed in the accompanying show notes and I found it with some googling:

.vimrc =>
command! TagFiles :call EchoTags()
function! EchoTags()
echo join(split(&tags, “,”), “\n”)

I found this coomand useful because my tags for rbenv ctags and gem-ctags were not loading and this helped me track the problem down.
