This is an Emacs mode for editing Turtle (RDF) files.

Note: I'm no longer actively developing this. I'm willing to accept pull requests; and if someone wants to take over the code, I'd probably take little persuading to agree.

It is based on an excellent start made by Hugo Haas. I've extended it to support indentation, some electric punctuation, and hungry delete.

To use, download the file ttl-mode.el from Github (or clone the project), put the file in the emacs load path (look at the variable load-path to find where emacs currently searches), and add something like the following to your .emacs file.

(autoload 'ttl-mode "ttl-mode" "Major mode for OWL or Turtle files" t)
(add-hook 'ttl-mode-hook    ; Turn on font lock when in ttl mode
          'turn-on-font-lock)
(setq auto-mode-alist
      (append
       (list
        '("\\.n3" . ttl-mode)
        '("\\.ttl" . ttl-mode))
       auto-mode-alist))
