C++ mode odd // behavior

C++ mode odd // behavior

[sellputcall]

emacs: GNU Emacs 25.3.1 (x86_64-redhat-linux-gnu, GTK+ Version 3.22.19) of 2017-09-14 

OS: Fedora 25 

Very odd behavior in C mode: status line has C/l pair Abbrev.
Editing a c++ header file.

When I type // it inserts a bullet point as of today!
Dont think i have seen this before.

I have to type:/ [space] [backspace] / to get // to take effect.


Other weird c++ navigation behavior, but will post that separately.


tia,

It might be the yas-snippet package. Try disabling the yas minor mode.
If it is indeed yas, then you should find the '//' definition and disable it

in cc-mode you can also select a region then C-c C-c to comment it out with '//'

I dont load yas mode. Nor do i find any info for yaz in apropos.

Yes, the comment region has been working fine in cc-mode. Still comments out regions.

If it is not yas it might be abbrev or
something else to that extent.

Did you do 'emacs -Q' and then find test.hh?
What mode are you in? Does the same thing
happen? If it doesn't, do 'C-h m' and flush it
to a file. Then go to your normal Emacs setup
where the incorrect behavior appears
(c++-mode), do the same, and then diff(1)
the files.

This doesnt always happen! Was happening consistently on the day I posted this.
I had my emacs and my system running entire day. Had booted that morning.

No. I always start with emacs --debug-init
If you want me to disable the init files, i can try.

> What mode are you in? Does the same thing
This only happened in C and C++ mode on that day.
Will have to observe if this happens again.

When it does, what exactly do you want me to flush to file?

If it doesn't happen anymore, I suppose you had
some minor mode enabled that you were
unaware on.

The buffer you see after hitting `C-h m'.
Do this when it is sane, on 'Emacs -Q', and
when it isn't sane, and then compare what minor
modes are then enabled that could make the
difference...

Yes, it felt like some conflict between c++ mode and some outline? mode that put bullet points instead of //.

Ok. Will save at the next emacs restart and save that buffer.

If I find anything, I will update this thread.

Thanks for all the help and the suggestions!
Very much appreciated.
