> how can I add missing language to my instance?

As a quick hack I added missing languages with this small addition to `app.yml`:

```plaintext
hooks:
  after_code:
    - exec:
        cd: $home
        cmd:
          - curl http://cdnjs.cloudflare.com/ajax/libs/highlight.js/8.2/languages/haskell.min.js >> $home/public/javascripts/highlight.pack.js
          - curl http://cdnjs.cloudflare.com/ajax/libs/highlight.js/8.2/languages/lua.min.js >> $home/public/javascripts/highlight.pack.js
          - curl http://cdnjs.cloudflare.com/ajax/libs/highlight.js/8.2/languages/tex.min.js >> $home/public/javascripts/highlight.pack.js

```
