vim-lsp

Multiple plugins are available to add LSP support in vim, such as coc.nvim (uses node.js, more features) or vim-lsp (lighter, written in vimscript). Neovim is also going to add native LSP support as well as tree-sitter in their 5.0 release, it's already available in nightly builds. The most straightforward option is probably coc.nvim, which tries to give a similar experience to VS Code out of the box. https://github.com/neoclide/coc.nvim https://github.com/prabirshrestha/vim-lsp https://github.com/neovim/nvim-lspconfig https://github.com/neovim/neovim

If you keep up with the LSP space, this is now possible with Vim https://github.com/eclipse/eclipse.jdt.ls https://github.com/georgewfraser/java-language-server Are both good examples. You'll need a corresponding client like this one https://github.com/prabirshrestha/vim-lsp There are others, but this one is pretty good. Next release of Neovim will have one built into the editor. Frankly, it's a bit of a hassle but once you get an LSP provider set up you can get one for just about any language you're using
