I think `syntax-ppss' has started returning incorrect information about
apostrophe-delimited strings in sql-mode in master. I am actually on
native-comp with this afternoon's master merged in myself, but I am
fairly confident you can reproduce this on master, nothing to do with
native-comp.
Steps to reproduce:
1. emacs -Q
2. Evaluate the following in *scratch*:
(let ((buf (generate-new-buffer "sql")))
(switch-to-buffer buf)
(sql-mode)
(insert "select '''")
(goto-char 1)
(delete-region 1 8)
(goto-char (point-max)))
Point should now be at the end of an `sql-mode' buffer containing
"'''" (three apostrophes).
4. Press backspace to erase the third apostrophe.
5. M-: (nth 3 (syntax-ppss)) RET
Expected result: fourth element of syntax-ppss, the delimiter character
for the current string, is nil, since we are no longer in a string
Observed result: fourth element is ?' (39), indicating that point is
still inside a string
My first guess is that this is related to commit 289d6b2265e and #40231.
I came across this while trying to get back something resembling the
behavior of `electric-pair-mode', and in particular
`electric-pair-skip-self', as it was prior to 289d6b2265e. I'm almost
there, but I ran into the above bug and got stuck.
Kind regards,
Dale
