Lua Array tables to Dictionary tables

[Santi]

I'm currently in need of some help, is there any way to make an array table (a regular one) into a "dictionary" one?
I need to convert this:

local t, v = {1,2,3,4}, {"1", "2", "3", "4"}

Into this:

local table = {1="1", 2="2", 3="3", 4="4")

Or is there any way by table.insert to make this kind of tables instead of the others?
Loops wouldn't solve the problem since I need to make this tables from scratch (t and v don't exist in my case, this is just an example)

 

[WarOfTheTitans]

t = {
	[1] = "1",
	[2] = "2",
	[3] = "3",
	[4] = "3",
	[5] = "5"
}

Edit:
Nvm... [didn't read your thread properly], sry

I barely understand you, but this might be what you want.. with loops .

local t, v = {1,2,3,4}, {"1", "2", "3", "4"}
local e = {}
for (i in pairs(t)) do
 e[i] = v[i]
end

Nop, that's the same as v, I need to somehow merge t and v or merge a regular table e.g

local t = {1,"1",2,"2",3,"3",4,"4"}

To a dictionary table like "table" shown in the first post.

 

[TGYoshi]

local t, v = {1,2,3,4}, {"1", "2", "3", "4"}
local e = {}
local a = 1;
for (i in pairs(t)) do
 e[i] = v[a]
 a = a + 1
end

Like that?

I don't know what u mean exactly and what you mean with "dictionary" all the time is still obscure to me, but I think the last version of TGYoshi is what you meant.
Maybe the example would be more clear if you had used different indices instead of 1, 2, 3, 4 in the t-array, because that is the index of the values in the v-array anyway.

If the script above still isnt what you meant feel free to give another explanation. =)

There are different ways:
We always start with an empty array 't': local t = {}

table.insert(t, 2)
Result: t = {2} or t = {[1] = 2}

table.insert(t, 55, 2) -- 55 is the position in the array
Result: t = {[55] = 2}

t[55] = 2 -- Same as table.insert example

t.colorred = "#FF0000" -- Same as t["colorred"]
Result: t = {colorred = "#FF0000"} or t = {["colorred"] = "#FF0000"}

Dunno if that helped.

When index starts with a number (no matter if it is a string or a number) you can only call it with brackets, otherwise it makes no different whether you reference it with brackets or a dot after the array name

No, uhm, okay let me try in some other way, let's imagine I want to print a list like the following:
Tic tac Orange
Piano White
Ipod Grey

Fine let's do it:

local t = {
["Tic tac"] = "Orange",
["Piano"] = "White",
["Ipod"] = "Grey"
}
--// same as my example:
local t = {tic tac="orange", piano="white" ipod="grey"

Okay so this is the way to do it, I'm aware of that (This is what I mean with dictionary table)
-
Fine, now let's say I want to make that exact thing, but by having a simple array table, just a simple table:

local t = {"Tic Tac", "Orange", "Piano", "White", "Ipod", "Grey"}

// or as my example (which is easily converted into ^):

local t, v = {"Tic tac", "Piano", "Ipod"}, {"Orange", "White", "Grey"}

Now, my question is how do I turn this table (the array one) into a dictionary one (the one above)

@Summ: That's exactly not what I mean, I'm not talking about Indexes, that's what you guys thought (passing v to e, so t indexes would be like in the table, but those are just integers not the indexes

 

[Summ]

So you got
local t = {}
and want it to get
local t = {
["Tic tac"] = "Orange",
["Piano"] = "White",
["Ipod"] = "Grey"
}
without defining it as this directly?

local t = {}

t["Tic tac"] = "Orange"
t["Piano"] = "White"
t["Ipod"] = "Grey"

Wish there was a picture which said: "Still not sure if searching for basic method or algorithm"

Kay, I struggled a bit with the code and the answer was really simple, thanks Summ

local s,v = {},{}
local goal = {}
for i = 1, 3 do
table.insert(s,i == 1 and "Tic tac" or i == 2 and "Piano" or "Ipod")
table.insert(v,i == 1 and "Orange" or i == 2 and "White" or "Grey")
end
for i = 1, 3 do
goal[""..s[i]..""] = ""..v[i]..""
end
