This is an Emacs mode for editing Context Free Design Grammar files, aka CFDG files.
This project was inspired by the cfdg-mode posted by Brent Sanders
at the Context Free Art Forums. This project share no code with
Mr. Sanders’ mode, though. Therefore, any error are our own.
/Context Free Art/ is am amazing program that generates images from context-free grammars, defined in Context Free Design Grammar syntax.
I am starting to play with CFDG and wanted syntax highlight for my scripts, but I could not find an editor with support for CFDG Version 3. So I decided to give it a try and write my on Emacs mode for it. It is the first time I try to do such a thing, so do not expect much, but if you find this mode useful, please be welcome to use it – at your own risk, notice that right now, this is pre-alpha software :-).
Put the cfdg3-mode.el file into your Emacs load path and add the
following into your Emacs init file (~/.emacs, ~/.emacs.d/init.el,
etc.)
(require 'cfdg3-mode)
(autoload 'cfdg3-mode "cfdg3-mode" nil t)
(add-to-list 'auto-mode-alist '("\\.cfdg\\'" . cfdg3-mode))As Mr. Xah Lee wrote in his tutorial on writing Emacs’s major modes:
A full featured language mode should also handle comments, indentation, keyword completion, function documentation lookup, function template insertion, graphical menu, supporting emacs’s customize-group scheme, or any other features that may be useful for coding the language your mode is designed for.
So, we wish for the future:
- Handle comments.
- Handle indentations.
- Keyword completion.
- Function documentation search.
- Graphical menu.
- Support for Emacs’ customize-group scheme.
- Rendering and viewing of images in Emacs.
- Multiline comments are not highlighted properly.
- The
transformshape adjustment is not highlighted properly. This is due to a conflict with thetransformcontrol structure. - The
iffunction is note highlighted properly. This is due to a conflict with theifcontrol structure.
