Package: emacs,cc-mode
Severity: wishlist

I had to edit some ObjC++ files today in my pathetic attempt to port
Dasher [1] to GNUstep.  Emacs opens .mm files in nroff-mode, and
manually switching to c++-mode or objc-mode does not give satisfactory
results.

Objective-C++ is supported by GCC and GNUstep Make, and although there
are currently no free programs written in this language (TTBOMK, apart
from the various free software ported to Mac OS X; but it's unusable
for other reasons), this is likely to change in the near future.

I realize this is Emacs 24 or 25 material; there is no problem about
that.

So it doesn't seem like just mapping .mm to objc-mode would give
satisfactory results, and I'm closing this bug report.

(If somebody wants to add a real mode for Objective-C++, that can, of
course, be done.)

Then why close this bug, which tracks exactly this feature request?

Personally, I don't want to spend the time (and the learning effort)
coding up an Objective-C++ Mode.  If anybody else wanted to do this
(most likely as a CC Mode derived mode), which might not be very much
work, I would be prepared to answer questions, and deliver support as
usual.

Because this request was about mapping .mm to objc-mode, which wouldn't
be appropriate, and a general request "can somebody write a brand new
mode for obscure language foo?" has little value in the bug tracker --
those types of requests seldom lead to anybody writing such a mode.

(The issue is still, of course, in the issue tracker, and anybody who
wishes to can refer to it if they should wish to write this new mode.
But it's not productive for the people doing triage of the open issues to
keep staring at the issue, year after year.)
