terraform-lsp

This has less to do with vim than with Terraforms poor LSP support. Vim/Neovim has had LSP support for some time with plugins and now built in natively. I use COC vim as it's the fastest to get started and I rarely have to do much config as it's based on VSCode and comes with sane bindings for go-to-def, refactoring and more. https://github.com/neoclide/coc.nvim https://github.com/prabirshrestha/vim-lsp https://github.com/neovim/nvim-lspconfig You can try to use either of these implementations: https://github.com/juliosueiras/terraform-lsp https://github.com/hashicorp/terraform-ls These are both fairly limited but you can see every editor (except intellij) uses this under the hood. I've used them at companies with 300+ terraform repos and have never had much of an issue navigating/understanding TF through Vim.

LSP is quite a life saver for me, I created https://github.com/juliosueiras/vim-terraform-completion first, but when terraform 0.12 came out, I move on to LSP implementation https://github.com/juliosueiras/terraform-lsp , since I wanted all editors to able to use it, and the biggest benefit is that I can use Terraform's HCL2 Parsing to parse the code, instead of using other languages
