title: Fish shell; import config into main config
body: <p>My <code>~/.config/fish/config.fish</code> is getting gigantic.</p>
  
  <p>What is the idiomatic way to write another file and "source" it from inside this file so my main config isn't so huge? </p>
  
  <p>Can I make like a <code>~/.config/fish/config-work.fish</code> and add <code>source ~/.config/fish/config-work.fish</code> into my main config?</p>
