Subject: 13.1.0; Company mode throws error when type "\lab" in a latex buffer
Date: Tue, 22 Feb 2022 00:40:41 -0700

Hi there,

As the title suggests, when working in a latex buffer, if I type
something starting with a backslash which has possible completions, such
as "\lab", "\mak" "\tex", company mode will throw an error. The error
trace back is as follows:

> Debugger entered--Lisp error: (wrong-type-argument stringp (lambda nil (interactive) (insert "\\parens*{") (push-mark) (insert "}") (exchange-point-and-mark)))

The first line in the output above is because I have the following code
in my init.el file:
(setq LaTeX-math-list '(("C-9" (lambda () (interactive) (insert "\\parens*{") (push-mark) (insert "}") (exchange-point-and-mark)) nil nil)))

The problem seems to be the new function
LaTeX--completion-annotation-from-math-menu does not like the anonymous
function in LaTeX-math-list. Is this a bug or should I just use named
functions in LaTeX-math-list?

Thanks in advance,
Ruiyang Wu

It's a bug which I've hopefully fixed right now.  I'll make a new ELPA
release ASAP.  Please report back if it works then.

Bye,
