It was thus said that the Great Thomas Jericke once stated:-----Original Message-----From: "Sean Conner" <sean@conman.org> How about: foo = { a = 1 , b = 2 , c = 3 } bar = { x = 'one' , y = 'two' , z = 'three' } baz = { one = 'alpha' , two = 'beta' , three = 'gamma' } a,b,c in foo = x,y,z in bar in bazDepends on the order of the in operarator, IMO it should be right to left: foo["a", "b", "x"] = baz["bar"]["x", "y", "z"] As baz["bar"] is nil, you will get: attempt to index field bar (a nil value)I think what you wanted to write is: a,b,c in foo = baz[x,y,z in bar]Interesting. Because in my mind, I was parsing it as a,b,c in foo = (x,y,z in bar) in baz (left to right) That is: foo.a = baz[bar.x] foo.b = baz[bar.y] foo.c = baz[bar.z] I'm not saying I'm right or you are wrong, just how I would interpet it. -spc (Anybody? Anybody? Bueller? Bueller?)
You have a mistake in you inner interpreter right there I wrote: a,b,c in table -> table["a", "b", "c"] If you want to expand left to right you get a,b,c in foo = (x,y,z in bar) in bazfoo["a", "b", "c"] = (bar["x, y, z"]) in bat -- syntax error: name expected near "(bar["x, y, z"])" The statements in front of the in must be names not expressions, if you start to mix them the code will get ambiguous. Example:
local t = {}
local table = { t = "lala" }
table[t] = "dada"
local test = t in table
print (test) -- lala or dada ?
