Hi,

I have this string expression in latex-mode:

$K(U_1, V_1, x_1; t_2, x_2)$

If the pointer is located on the opened "(" and I run "forward-sexp" it 
works and the
pointer goes after the closed ")".

But if, again, the pointer is located on the opened "(" and I evaluate
"(sexp-at-point)" it returns nil.

If I remove the ";" symbol from the expression it works and returns the 
sexp-at-point:

$K(U_1, V_1, x_1 t_2, x_2)$

Is it a bug?

Best regards,

Gabriele

This suggests you are using the major mode from AUCTeX, rather than the
built-in latex-mode?  Is this right?

No, I'm using the built-in latex-mode. AUCTeX is not installed on my

I don't think it's a bug.  forward-sexp moves across balanced
expressions, so it is not specific to Lisp.  By contrast,
sexp-at-point is specific to Lisp and Lisp-like syntax, and so it uses
the buffer's syntax.  Which is why ';' affects the result.

Adding Stefan in case he has comments for this.

AFAICT, `sexp-at-point` correctly finds the parenthesized thingy, but it
is asked to return the Lisp object it represents rather than a string,
so it `read`s, which inevitably obeys the ELisp syntax.

IOW, I suspect you want (thing-at-point 'sexp) rather than
(sexp-at-point).
