Persistent :set syntax for a given filetype?

Question

I\'m working on a Symfony2 project which uses Twig, and the filetypes are myfile.html.twig. Vim doesn\'t automatically detect the syntax highlighting and so applies

Answer 1

au BufNewFile,BufRead,BufReadPost *.twig set syntax=HTML

And add this line to ~/.vimrc to make the settings persistent.
