Best Way to Set up Ctags with Neovim and Vim 8

Ctags are a great way to navigate large projects when using Vim or Neovim by jumping to definition with a simple command. With the recent addition of async jobs in Vim 8 and Neovim, you can now generate your project’s tags in the background, making the whole process relatively seamless.

First, we’ll install universal-ctags for our OS. Universal-ctags is an actively maintained ctags implementation (as of November 2017). This tool will allow us to generate the tag file for our project:

Using homebrew:

Next, we’ll install vim-gutentags which is an awesome plugin that makes managing our tag file painless. When opening a project for the first time, vim-gutentags will kick off the creation of our tag file in the background. For subsequent opens, it will asynchronously update our tag file on save.

And install:

Navigate to a project that you’d like to generate tags for and open it with Vim or Neovim. The tag creation will kick off in the background and it may take a few minutes for it to finish depending on the size of the project. Once finished, you can use C-] to jump to definition.

Enjoy project navigation bliss.
