title: How to use different colorscheme and syntax highlighting in vim?
body: <p>Suppose I want to use this colorscheme:
  <a href="https://github.com/NLKNguyen/papercolor-theme" rel="nofollow noreferrer">https://github.com/NLKNguyen/papercolor-theme</a></p>
  
  <p>I copied the PaperColor.vim file into .vim/colors and made my .vimrc:</p>
  
  <pre><code>syntax on
  colorscheme PaperColor
  background=light
  </code></pre>
  
  <p>Now, I want to use this syntax highlighting for haskell files: <a href="https://github.com/raichoo/haskell-vim/tree/master/syntax" rel="nofollow noreferrer">https://github.com/raichoo/haskell-vim/tree/master/syntax</a></p>
  
  <p>There are two syntax highlighting files. Which one am I supposed to use, and where do it put them?</p>
  
  <p>Thanks!</p>
  
  <p>Do I put it in ./vim/syntax and vim auto-loads all files in ./vim/syntax folder?</p>
  
  <p>It seems like to load haskell.vim automatically. But doesn't load cabal.vim. Wondering if it only loads haskell.vim when I open .hs files? I'm trying to make it like that. Can vim load multiple syntax files at once?</p>
