Gutentags is a plugin that takes care of the much needed management of tags files in Vim. It will (re)generate tag files as you work while staying completely out of your way. It will even do its best to keep those tag files out of your way too. It has no dependencies and just works.
Install Gutentags like any other Vim plugin. I recommend something like Pathogen, so you can go:
cd ~/.vim/bundle hg clone https://bitbucket.org/ludovicchabant/vim-gutentags
If you're more into Git than Mercurial:
git clone https://github.com/ludovicchabant/vim-gutentags.git
Then you only need to do a
:call pathogen#helptags() to generate the
documentation tags (how ironic, eh?) and you can access Gutentags' help pages
In order to generate tag files, Gutentags will have to figure out what's in
your project. To do this, it will locate well-known project root markers like
SCM folders (
.hg, etc.), any custom tags you define (with
gutentags_project_root), and even things you may have defined already with
other plugins, like CtrlP.
If the current file you're editing is found to be in such a project, Gutentags will make sure the tag file for that project is up to date. Then, as you work in files in that project, it will partially re-generate the tag file. Every time you save, it will silently, in the background, update the tags for that file.
Usually, ctags can only append tags to an existing tag file, so Gutentags removes the tags for the current file first, to make sure the tag file is always consistent with the source code.
Also, Gutentags is clever enough to not stumble upon itself by triggering multiple ctags processes if you save files too fast, or your project is really big.
There are some similar Vim plugins out there (
vim-automatic-ctags, etc.). They all fail on one or more of the requirements
I set for myself with Gutentags:
seetags for deleted or renamed classes and functions.
I hope Gutentags will bring you as much closure as me regarding tag files. I know I don't want to have to think about it, and probably neither do you.
