This is an Emacs major mode for writing Turtle files that supports basic syntax highlighting and indentation.
In particular, it supports multi-line string literals reasonably well, unlike similar older modes (that I am aware of, anyway). That said, it is far from perfect and may not support more esoteric files or various corner cases of the grammar well. See the comments in the source code for details and caveats.
Put turtle-mode.el in your load path and add something like the following to
your init.el:
(require 'turtle-mode)
(add-to-list 'auto-mode-alist '("\\.n3" . turtle-mode))
(add-to-list 'auto-mode-alist '("\\.ttl" . turtle-mode))Always welcome. This mode is rather hastily written and is not at all comprehensive, but it has been written from scratch in an attempt to make things as clear as possible and should hopefully be easy to work with.
Configuration support is one obvious area for improvement. It could also probably be extended to support TriG relatively easily. If someone versed in the dark arts of font-lock could fix the laggy long-string highlighting, that would be particularly appreciated.
