I think it's easier that c++-ts-mode doesn't touch that variable at all
and leave it set to "\n". I can't see it being much use, with or
without electric-pair-mode in the mix.
Following up on this, I have now tried c++-ts-mode for a while now and
can confirm this jumping-around-while-typing is terrible without
electric-pair-mode, and still pretty bad even with electric-pair-mode.
Here's just an example with emacs -Q + electric-pair-mode + c++-ts-mode
Start typing
i n t SPC m a i n ( ) SPC { RET
The buffer becomes
int main() {
<- point here
}
So far so good. Point is correctly indented at column 2 (because
electric-pair-mode has balanced the buffer and electric-indent-mode did
its thing on RET).
Type 'std'. Nothing surpising happens, good. Now type one ':' and see
the 'std:' be electrically indented to column 1, type the other ':' and
the 'std::' now jumps to column 2 again.
In bug#62412, Theo said is was OK with killing the custom setting of
electric-indent-chars in c-ts-mode.el and leave it set to the default.
Though a number of indenting problems would remain after that, at least
this one clear annoyance would be solved. So if there are no
objections, I propose to apply this patch.
