My Vimrc File

.vimrc

"
" Darin's configuration file for vim/neovim
"
" My relatively minimal vimrc/init.vim file
" Most plugins are mostly simple and don't use too much vim magic
"
" I have lots of custom setups for different languagues like Clojure, Rust,
" and Go, so if you do not use these languages, you might be better off with 
" a simpler vimrc.
"
" Set up instructions
"
" 1. Copy this file to ~/.vimrc (or ~/.config/nvim/init.vim if you are using
" neovim)
" 2. Clone vundle as ~/.vim/bundle/vundle
" 3. Open vim/nvim and type :PluginInstall
" 4. If you want autocomplete, cd into ~/.vim/bundle/YouCompleteMe
" and run ./install.py --clang-completer --gocode-completer --rust-completer
" 5. Edit the Rust configuration to add the path to the rust source code

"
" Autocommands
"
" Sets relative line numbering when entering a buffer, set line highlight
" on cursor, and set timeout from visual mode for nerdcommenter
autocmd BufEnter * set relativenumber | set nu | set cursorline | set timeoutlen=5000
