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

This is based on ttl-mode.el from Peter Vasil, and is not that much modified.

I discovered that I can use my experimental syntax with {} for nested named nodes with this ttl mode, I do not need to extend it.

OTOH I need to add to the syntax table at least to recognise QNames as symbols, so the current ttl-mode does not cut it.

**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](https://github.com/nxg/ttl-mode) (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 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
        '("\\.ttl" . ttl-mode)
        '("\\.ntl" . ttl-mode))
       auto-mode-alist))
