Is there a way to skip some middle optional arguments? For example for this function:
f[{a_: 80, b_: 90}, {c_: 30, d_: 20}] :=
Print["a=", a, ", b=", b, ", c=", c, ", d=", d]
Call something like this:
f[{(* empty or some symbols*), 3}, {4, 5}]
and get the result:
a=80, b=3, c=4, d=5
P.S. Function will have many parameters and will have complicated form, so the answer described here may be not applicable.
Longest. Another option is to explicitly passAutomaticor similar to the function, and then do some preprocessing inside the function. But personally, I would strongly consider just passing in all values as named options in cases like these: Then it is trivial to skip arguments, and it is very clear which arguments are assigned for any given call $\endgroup$
