Re: Syntactic sugar for function calls

[Ben Sunshine-Hill <bsunshin@...>]

I'm doing something similar. Here's my current setup. I'm using 5.0beta.

areas = {}

function nominate(t) -- takes a numeric array, 
				-- and makes it an associative table
				-- through each member's "name" member
	table.foreachi(t, function(i, v)
		t[v.name] = v
		t[i] = nil
	end)
end

function area(area)
	nominate(area.rooms)
	if not area.name then
		error "Need to name this area"
	end
	areas[area.name] = area
end

function room(room)
	if not room or not room.name then
		error "Need to name this room"
	end
	return room
end
	
area {
	name = "house"
	rooms = {
		room { 
			name = "bedroom"
			desc = "Joe's Bedroom"
			foo = function()
				print("Hello!")
			end
		},
		room { 
			name = "bathroom"
			desc = "Wendy's bathroom"
		}
	}
}

print(areas["house"].rooms["bedroom"].desc)
print(areas["house"].rooms["bathroom"].desc)
areas["house"].rooms["bedroom"].foo()

Hope this helps.
