make vim a good editor for Golang and Scala

editor.md

To switch back between Golang and Scala: init.vim and init.lua

Golang

I followd the guide provided by this guy (https://octetz.com/docs/2019/2019-04-24-vim-as-a-go-ide/) and faced some problems:

• The vim.plug should be copied inside ~/.config/nvim/autoload/ not ~/.var/app/io.neovim.nvim/data/nvim/site/autoload/.
• The command :GoInstallBinaries installs the binaries like gopls (in my case) inside $HOME/go/bin. Therefore, $HOME/go/bin must be appended to the $PATH variable.

if [ -d "$HOME/go/bin" ] ; then
  PATH="$PATH:$HOME/go/bin"
fi

• gcc was not installed by default in my distribution (Ubuntu 20.04) while it was necessary for installation of some binaries.
  • To install gcc:

  apt install build-essential
  

  To verify installation:

  gcc --version
  

• :GoInstallBinaries didn't install gocode, gocode-gomod, gogetdoc, golint, gometalinter.
  • To install golint:

  apt install golint
  

  • To install godoc: https://installati.one/ubuntu/20.04/gocode/

Additional Notes

• Remove nvim using apt-get.
• Install nvim using app image.
• Move nvim app image to /use/bin/nvim.
• Point vim to nvim (alias in .bashrc).
• ~/.config/nvim: nvim dir
• ~/.config/nvim/autoload/plug.vim: for loading plugins
• coc: language server (nvim has also LSP itself)
• init.vim: LSP key bindings, etc.
• ~/.vim: Pluggins are installed here.
• init.lua vs init.vim
