Topic: Closed: Test yourself (for fun). Round 2. The winner is John Kaul (Se7en)

[divtiply]

Recognize the name of (lambda (x y) (not (vl-member-if-not x y)))
(This function is exists in current AutoCAD's Lisp)

[Bhull1985]

(vl-member-if)
?

[JohnK]

I'd say vl-every but that's Visual Lisp.

[divtiply]

I'd say vl-every but that's Visual Lisp.

CORRECT!
VisualLisp is current AutoCAD Lisp

[JohnK]

I am the smartest man alive!

[divtiply]

I am the smartest man alive!

Bonus round:
Can you define vl-some?

[JohnK]

Off the top of my head? No!? To be honest, I haven't done any lisp in almost 7 years now (I'm a C++ guy); I had to look through the list of functions to get the "vl-every answer".  My Auto/Visual Lisp knowledge is running on fumes.

[VovKa]

I'd say vl-every but that's Visual Lisp.

CORRECT!
VisualLisp is current AutoCAD Lisp

but it is not 'absolutely' correct

Code: [Select]

(vl-every '= '(1 2 3) '(1 2 3))

[divtiply]

Yes, it can accept only one list.

Actually, the answer in current terms is
(lambda (x y) (and (vl-member-if x y)))
That why it is a bonus question...
