A Tale of Two Vims

I have two primary vim onfigurations depending on what I am feeling. I have my “everything is modern” configuration that I will bring out if I need to get a lot of work done. Which is below. This has autocomplete, nice dark theme, git integration, airline like, nerdtree, ctrlp, and with COC it has strong support for nearly every language. It is like running VSCode in the terminal, works fantastique.

" Specify a directory for plugins
" install vim-plug curl -fLo ~/.vim/autoload/plug.vim --create-dirs
" open up vim and run :PlugInstall
" exit and reopen then run :CoCinstall coc-java
" or whater Coc plugin you want
" - For Neovim: stdpath('data') . '/plugged'
" - Avoid using standard Vim directory names like 'plugin'
call plug#begin('~/.vim/plugged')

" Using a tagged release; wildcard allowed (requires git 1.9.2 or above)
Plug 'fatih/vim-go', { 'tag': '*' }
Plug 'itchyny/lightline.vim'
Plug 'tpope/vim-fugitive'
" Initialize plugin system
call plug#end()

"Use 24-bit (true-color) mode in Vim/Neovim when outside tmux.
