How to split string into chars and put them into array (list)?
I want to create 1, specific string and then put them into the array like this:
1 | local myString = "example string" |
and then get in result:
1 | local myList = {"e","x","a","m", etc. } |

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.
1 | local myString = "example string" |
2 | local myTable = {} |
3 |
4 | for character in string.gmatch(myString,".") do |
5 | table.insert(myTable, character) |
6 | end |
then if you want, you can literate over the table and print each character or value.
1 | for _,v in pairs(myTable) do |
2 | print(v) -- just prints the value or the character |
3 | end |
- e
- x
- a
- m
- p
- l
- e
- s
- t
- r
- i
- n
- g

Just in case for anyone who might not know what is gmatch, it returns an iterator function, kinda like how pairs returns next User#24403 69 — 6y

This is easily done with just string.sub and a basic for loop.
1 | function getChars(InputString) |
2 | local ret = {} |
3 | for local i = string.len(InputString), 1, -1 do -- For every character |
4 | ret[i] = string.sub(InputString,_,_) -- Add this character to the table |
5 | end |
6 | return ret |
7 | end |

why are you using _ User#24403 69 — 6y

^ 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. turtle2004 167 — 6y

Thanks for help, I don't need it, as @up already did explain, but thanks for help, meaning is the most important. ;) NorteX_tv 101 — 6y
