hello emacs users
generally, i use looking-at as follows
(when (looking-at "desired_pattern")
( do_this_and_that
(do some more things)
(when (looking-at "anther_ desired_pattern")
( do_this_and_that)
)
)
whats your expert advice on how to modify if the cursor is not at the
desired pattern in either case so that an error message is reported ?
should I wrap the looking-at in cond or can I add some kind of default
ie else like functioning clause to when ?
