Does it support different ctags file chosen dynamically? about vim-gutentags HOT 2 CLOSED

As what I understand, you want to create different tagfiles for different files of one repos.

So, for example, we have cpp and py files in a repos. How to create two tags for cpp and py respectively？Here is my solution.

let g:gutentags_ctags_tagfile=&filetype.'.ctags' #optional 
au BufEnter,BufRead * let g:gutentags_ctags_tagfile=&filetype.'.ctags'

use echo g:gutentags_ctags_tagfile in vim to check your tagfile name when you open a file or switch between two files.

That's a nice trick @wow-yes thanks.

I think @marcelolima was maybe asking about switching the tagfile used for looking up a symbol? In that case, I think that temporarily setting the tags variable would work (see :help 'tags'), but frankly vim does a good job of handling multiple tag files anyway, so setting that variable to both tag files (separated by a space or comma) would let vim search both when typing g]. Usually gutentags sets that variable automatically but that could mess-up your setup in this case, so you can disable that with g:gutentags_ctags_auto_set_tags.
