How can I configure Emacs to recognise certain she-bang lines?it recognises the shebang line:#!/usr/bin/env rubybut not the shebang line of#!/usr/bin/env ruby1.9I figure there must be an alist somewhere with the list of scripting languages called by /usr/bin/env  and the mode, but I can't find it.
emacs: recognising the shebang line
emacs
This is controlled by interpreter-mode-alist. In my Emacs (23.2.1 on Debian), there's an entry for ruby1.9 out of the box. I guess you have an older version; you can add this to your .emacs:(add-to-list 'interpreter-mode-alist             '(ruby1.9 . ruby-mode))
