SKILL equivalent of TCL "splatter" operator

liorscotland

Hello all. Let us assume the we have a list list1, of 2 elements. I need to feed those 2 elements as separate arguments to a proc, say proc1.
What that I would do in skill is:
proc1(   car(list1) cadr( list2  )
In TCL, I would do this:
proc1 [ lindex $list1 0] [lindex $list1 1]
or... Us the splatter operator:
proc1 {*}$list1
Naturally, the 2nd way is easier, and scalable, whereas the 1st way is not scalable, if proc1 can accept an arbitrary number of arguments.
Is there a way to achieve the same in SKILL?
Thanks.

    Hi Lior,

    Interesting - I'm not familiar with the 'splatter' operator in Tcl (and I know Tcl pretty well), but the way to do this in SKILL is to use the apply function: apply('proc1 list1).

    E.g. apply('plus list(1 2 3)) => 6

    Hopefully this does what you want. BTW, I'm assuming that the 'list2' above is a typo.

    Best regards,
    Lawrence.
