" Add Airline for nice status bar, and some themes for it
Plug 'vim-airline/vim-airline'
Plug 'enricobacis/vim-airline-clock'
Plug 'vim-airline/vim-airline-themes'

Plug 'tpope/vim-markdown' "markdown syntax
Plug 'ap/vim-css-color' "displays the actual colour of the css color picked
Plug 'morhetz/gruvbox' "some colour theme
Plug 'NLKNguyen/papercolor-theme' "another colour theme - seems like gruvbox doesn't really work with spelling

" Paint css colors with the real color
" Plug 'lilydjwg/colorizer'

" Relative numbering of lines (0 is the current line)
" (disabled by default because is very intrusive and can't be easily toggled
" on/off. When the plugin is present, will always activate the relative
" numbering every time you go to normal mode. Author refuses to add a setting
" to avoid that)

" FINDING FILES: ************************************************

" Search down into subfolders
" Provides tab-completion for all file-related tasks
set path+=**

" Display all matching files when we tab complete
set wildmenu

" NOW WE CAN:
" " - Hit tab to :find by partial match
" " - Use * to make it fuzzy
"
" " THINGS TO CONSIDER:
" " - :b lets you autocomplete any open buffer
"
"
" TAG JUMPING ***************************************************
"
" " Create the `tags` file (may need to install ctags first)
command! MakeTags !ctags -R .
"
" " NOW WE CAN:
" " - Use ^] to jump to tag under cursor
" " - Use g^] for ambiguous tags
" " - Use ^t to jump back up the tag stack
"
" " THINGS TO CONSIDER:
" " - This doesn't help if you want a visual list of tags

" AUTOCOMPLETE **************************************************
"
" " The good stuff is documented in |ins-completion|
"
" " HIGHLIGHTS:
" " - ^x^n for JUST this file
" " - ^x^f for filenames (works with our path trick!)
" " - ^x^] for tags only
" " - ^n for anything specified by the 'complete' option
"
" " NOW WE CAN:
" " - Use ^n and ^p to go back and forth in the suggestion list
"
" FILE BROWSING *************************************************
"
" " Tweaks for browsing
let g:netrw_banner=0        " disable annoying banner
let g:netrw_browse_split=4  " open in prior window

let g:netrw_list_hide=netrw_gitignore#Hide()
let g:netrw_list_hide.=',\(^\|\s\s\)\zs\.\S\+'
"
" " NOW WE CAN:
" " - :edit a folder to open a file browser
" " - <CR>/v/t to open in an h-split/v-split/tab
" " - check |netrw-browse-maps| for more mappings
"
" SNIPPETS *******************************************************
"
" " Read an empty HTML template and move cursor to title
nnoremap ,html :-1read $HOME/.vim/.skeleton.html<CR>3jwf>a
"
" " NOW WE CAN:
" " - Take over the world!
" "   (with much fewer keystrokes)
"
"
" BUILD INTEGRATION **********************************************
"
" " Steal Mr. Bradley's formatter & add it to our spec_helper
" " http://philipbradley.net/rspec-into-vim-with-quickfix
"
" " Configure the `make` command to run RSpec
" set makeprg=bundle\ exec\ rspec\ -f\ QuickfixFormatter
"
" " NOW WE CAN:
" " - Run :make to run RSpec
" " - :cl to list errors
" " - :cc# to jump to error by number
" " - :cn and :cp to navigate forward and back

" SPELLING ********************************************************

" only enable it on buffers containing files with potential prose
