local myString = "example string"
and then get in result:
local myList = {"e","x","a","m", etc. }

How to split string into chars and put them into array (list)?

you use string.gmatch() and use the "." string pattern, which is every character inside a string. then just literate over it and insert each character into a table.
local myString = "example string"
local myTable = {}
for character in string.gmatch(myString,".") do
table.insert(myTable, character)
end
then if you want, you can literate over the table and print each character or value.
for _,v in pairs(myTable) do
print(v) -- just prints the value or the character
end
- e
- x
- a
- m
- p
- l
- e
- s
- t
- r
- i
- n
- g
This is easily done with just string.sub and a basic for loop.
function getChars(InputString)
local ret = {}
for local i = string.len(InputString), 1, -1 do -- For every character
ret[i] = string.sub(InputString,_,_) -- Add this character to the table
end
return ret
end

why are you using _

^ You should only use _ if it's a value that won't be used. E.g for _, v in pairs. If you have no need for the index.

Thanks for help, I don't need it, as @up already did explain, but thanks for help, meaning is the most important. ;)

Changed it to not use _

Just in case for anyone who might not know what is gmatch, it returns an iterator function, kinda like how pairs returns next
Thanks, very helpful. :D
