changing g:gutentags_ctags_tagfile causes broken tags file

[crichardson332]

Describe the bug I'm trying to have gutengtags put the generated tags file into the .git directory. By default, it creates a tags file in the project root, which causes untracked files in git for every single repository, which in my case is many. However, when I change g:gutentags_ctags_tagfile to '.git/tags', according to this thread, the relative paths in the resulting tags file are missing the "../" needed to move out of the ".git" directory (for example, it contains src/module/file.cpp). Vim then tries to look for ".git/src/module/file.cpp" and fails.

Steps to reproduce

• Add let g:gutentags_ctags_tagfile = '.git/tags' to vimrc
• Open a course file in a c++ project (I'm working with this project)

Should be fixed with aa67e48f6c071ef4179dc30ac24ddf93e5eb6338, thanks!

I'm experiencing the same bug (with the same config as the OP, but on neovim and on Ubuntu 19.10: I use the gutentags plugin in combination with vimtex, not sure whether that's relevant). I've tried checking out past commits and, at least in my case, the bug was fixed by https://github.com/ludovicchabant/vim-gutentags/commit/aa67e48f6c071ef4179dc30ac24ddf93e5eb6338, and then reintroduced by https://github.com/ludovicchabant/vim-gutentags/commit/259a45af1b015addc9e17799e7c6caf982bd5b71.
