"  Vundle
" --------
" The following section configures the Vundle plugin mgr and assumes you've run:
" $ git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
" Don't forget to launch vim and run :PluginInstall
set nocompatible              " be iMproved, required
filetype off                  " required

" set the runtime path to include Vundle and initialize
set rtp+=~/.vim/bundle/Vundle.vim
call vundle#begin()
Plugin 'VundleVim/Vundle.vim'

" add plugins here
Plugin 'dense-analysis/ale'      " automatic linting with wide language support
Plugin 'morhetz/gruvbox'         " theme, plays nicely with gitgutter and airline
Plugin 'airblade/vim-gitgutter'
Plugin 'vim-airline/vim-airline'

" All of your Plugins must be added before the following line
call vundle#end()            " required
filetype plugin indent on    " required
" To ignore plugin indent changes, instead use:
"filetype plugin on
"
" Brief help
" :PluginList       - lists configured plugins
" :PluginInstall    - installs plugins; append `!` to update or just :PluginUpdate
" :PluginSearch foo - searches for foo; append `!` to refresh local cache
" :PluginClean      - confirms removal of unused plugins; append `!` to auto-approve removal
"
" see :h vundle for more details or wiki for FAQ
" Put your non-Plugin stuff after this line

" Better color support for the theme:
set termguicolors
colorscheme gruvbox
