In the language Lua was written in C, arrays will not automatically resize. If you add values to arrays, Lua will automatically resize the arrays. However, this is all handled behind the scenes. For people only familiar with Lua and other high-level languages, arrays are in general dynamic. Some ideas might seem obvious to you if you have a background in a lower-level language, but for the people who are only familiar with Lua, I will try and explain this in Lua as much as possible.įor the example code I am going with readability and easy to explain code over efficient and optimized code. This explanation is ment for people who only know Lua. I will explain the optimisations used by Lua in another post, as this tutorial is only ment to explain how hash tables work. This library is not included by default in Lua 5. For writing the hashing functions I am going to assume there is a bit32 library. Take note that this code is intended for vanilla Lua, and will only support part of Roblox Lua.

We will however go into more things than only tables. OK, I Understand.I will try to explain how tables work internally within Lua 5.

Beginner's Roblox Scripting Tutorial #18 - Tables (Beginner to Pro 2019) The output also keeps lua syntax and the script can easily be modified for simple persistent storage by writing the output to file if modified to allow only number, boolean, string and table data types to be formatted.

In my personal usage of this function, it outputted 63k lines to file in about a second. It should also be capable of handling really large tables due to the way it handles concatenation. This print table function that I've written does not have this problem. Most pure lua print table functions I've seen have a problem with deep recursion and tend to cause a stack overflow when going too deep. Sign Upit unlocks many cool features! Lua 2.
