Hello --
I am a long term Emacs user and I use flymake together with flymake-cursor on a daily basis.
Starting Emacs 26.1, I noticed that flyamke was redesigned and no longer has the var flymake-err-info that contains the error info reported by the backend syntax checker.
This makes flymake-cursor and code like the following not work:
(defun elpy-flymake-error-at-point ()
"Return the flymake error at point, or nil if there is none."
(when (boundp 'flymake-err-info)
(let* ((lineno (line-number-at-pos))
(err-info (car (flymake-find-err-info flymake-err-info
lineno))))
(when err-info
(mapconcat #'flymake-ler-text
err-info
", ")))))
I believe this is a potential issue and wonder if someone could direct me to any alternatives to flymake-err-info in the newly designed flyamke.
Thanks.
Dave

Hi Da Zhang,
I'm the responsible for the redesign. Although I tried to keep *some*
backward compatibility to old flymake.el's API, the truth is that *all*
of it was an API.
The bad news is that this variable is gone: it couldn't be
backward-adapted. The good news is that it should be much easier to
write your function:
(defun elpy-flymake-error-at-point ()
"Return the flymake error at point, or nil if there is none."
(mapconcat #'flymake-diagnostic-text (flymake-diagnostics (point)) "\n"))
Notice that, to keep with the protocol, this returns a concatenation of
the text strings of all the errors at point. You might be better served
by returning and manipulating the objects returned by
flymake-diagnostics instead.
See section "2.2.1 Flymake utility functions" of the Flymake manual
bundled with Emacs for more information.
I don't know what flymake-cursor does, but I suspect it can be fixed
accordingly.
Hope this helps,
João

I believe (fboundp 'flymake-diagnostics) is a simple and effective enough
check.
Incidentally, I don't know what elpy does in regards to syntax checking,
but it might have been completely or partially superseded by the new
flymake python backend.
