13:39 <Hunar> Hello, I have a weird problem that I cant reproduce elsewhere.. I have a function drawLine which takes 4 parameters, now this (apply drawLine '(10 10 50 60)) and this  (apply drawLine (conc '(10 10 50 60))) work but this (apply drawLine (conc '(10 10) '(50 60))) causes stack overflow with this error message (apply drawLine (conc '(10 10 . (50 60

13:39 <Hunar> .)) '(50 60 .))) which I don't understand, why would (conc '(10 10 50 60)) be different than (conc '(10 10) '(50 60)) aren't they the exact same thing?

13:42 <abu[m]> Keep in mind that 'conc' is destructive

13:42 <abu[m]> In general, unless you want to modify structures, use 'append'

13:43 <abu[m]> (btw, lists starting with a number don't need to be quoted)

13:43 <Hunar> Aha, so that was my problem .. I keep forgetting those :(

13:44 <abu[m]> Yeah ☺ 'conc' is powerful but dangerous like all destructive functions

13:44 <Hunar> Right, I forgot that too

13:45 <Hunar> I forgot another thing, apply passes the arguments that are after the list to the beginning, which function passes it to the back?

13:46 <Hunar> (apply fun '(a b c) thing) I want it to become (fun a b c thing)

13:46 <abu[m]> You mean while calling 'apply'?

13:46 <abu[m]> ok, no, there is no direct way

13:46 <abu[m]> You must build the list then

13:47 <Hunar> Ah, I will just append it to the list then

13:47 <abu[m]> (apply fun (append '(a b c) (list thing))

13:47 <abu[m]> yeah, not very beautiful

13:47 <abu[m]> Do you need 'apply' here?

13:48 <Hunar> I plan to restart my raylib port, some functions take position which is a struct, and some functions take individual x y points, I needed to extract the points to pass it

13:49 <abu[m]> Makes sense then

13:50 <Hunar> Thanks :)

13:50 <abu[m]> ☺
