The min challenge

Scripting Forums AppleScriptObjC and Xcode

A small challenge to any ASOC guru’s out there.

How would you code the following objective-c in ASOC:

float     minX = MIN(MIN(MIN(point0.x, point1.x), point2.x), point3.x);

I have come up with this, does anyone have a better solution?


	set tList to {tPoint0's x, tPoint1's x, tPoint2's x, tPoint3's x}
	set minX to min_(tList)

	on min_(theList)
		set minVal to theList's item 1
		repeat with i from 2 to count theList
			if theList's item i < minVal then
				set minVal to theList's item i
			end if
		end repeat
		return minVal
	end min_

This works too:

on min(a, b)
	if a < b then
		return a
	else
		return b
	end if
end min

set x to min(min(min(min(5, 4), 3), 2), 9)

The advantage is that you can use it on as many variables as you need to. Yours is a bit easier to read, IMHO
