Neovim configuration

README.md

• VimPlug: https://github.com/junegunn/vim-plug (easy to install)
• coc-nvim requires nodejs >= 8.10.0 as it uses a variation of VSCode's LSP implementation: https://github.com/neoclide/coc.nvim/wiki/Install-coc.nvim
• Language Server setup for coc-nvim. Some have their own coc plugins you just install once and be done, others need config: https://github.com/neoclide/coc.nvim/wiki/Language-servers
  • Ruby Solargraph LSP can be installed from within Neovim using :CocInstall coc-solargraph
  • Golang gopls needs to be configured in the coc-settings.json file (see attached file).
• The LSP you want to use with neovim must be installed (same as with VSCode).
  • Ruby gem install solargraph
  • Golang go get golang.org/x/tools/gopls
  • Puppet git clone git@github.com:lingua-pupuli/puppet-editor-services.git
