DDOC support?

[russel]

Having DDOC support in the comments is something a number of people would like, both formatting and font-lock. I believe the URL you highlight is the definitive statement of DDOC.

As for process:

• Use a feature branch and work on d-mode.el. The master branch is the rolling release branch, and we need to get something fairly complete before we merge it in.
• It would be good if we can get into doing some tests for this, to avoid the historic Emacs mode problem of untested code. There are already a few tests in place for some of the comment formatting.

Ideally, DDoc support would also support highlighting .ddoc and .dd files.

I started working on one, a very early / rudimentary draft is here:
https://github.com/CyberShadow/ddoc-mode

There are already a few tests in place for some of the comment formatting.

That information is outdated. d-mode now has 91% test coverage.

OK, that coverage figure works for me. :-) Let's try and keep it high enough for our confidence.

Might it be worth having separate modes for .d, and .ddoc and .dd files with some shared code?

Yes, that makes sense.

I was planning to do some research on how to properly have a region of code highlighted in some way different from the rest of the code. Apparently doing it correctly is really, really hard in Emacs. (This is also why we still get glitches with string escapes that disappear when you make some edit and undo it.)

@CyberShadow great initiative on ddoc-mode.

Have you looked at org-mode way to handle syntax highlighting in code blocks? http://orgmode.org/
It works quite smoothly in my experience. Another example is polymode:

Polymode is an emacs package that offers generic support for multiple major modes inside a single emacs buffer. It is lightweight, object oriented and highly extensible. Creating new polymodes typically takes a few lines of code.

Polymode does not seem to be as stable as orgmode considering only this aspect of multi-mode support.
