Created page with "== Calling Convention == Call local r[,...] = sl.non([...]) Args a1...aN are of any type Results r1...rN are boolean == Usage Example == local sl = dofile(getinstalldir()....."

New page

== Calling Convention ==
Call
local r[,...] = sl.non([...])
Args
a1...aN are of any type
Results
r1...rN are boolean

== Usage Example ==

local sl = dofile(getinstalldir()..'/lib/simplelib.lua')
non = sl.non
null = sl.null
local a,b,c,d = non(false,nil,null,0)
print(a)
print(b)
print(c)
print(d)

--> 'false'
--> 'true'
--> 'true'
--> 'false'

== Description ==

Tests each supplied argument as to whether it is [[nil]] or [[null]]. If so, then non returns true for that value, otherwise false. non returns the same number of values as the number of arguments it accepted.

== Upon Error ==

If non receives no arguments, then it returns a single nil value.
