You can make patterns more useful with character classes. A character class is an item in a pattern that can match any character in a specific set. For instance, the class %d matches any digit.2.4 – Strings. Strings have the usual meaning: a sequence of characters. Lua is eight-bit clean and so strings may contain characters with any numeric value, including embedded zeros. That means that you can store any binary data into a string. Strings in Lua are immutable values.11.1 – Arrays. We implement arrays in Lua simply by indexing tables with integers. Therefore, arrays do not have a fixed size, but grow as we need. Usually, when we initialize the array we define its size indirectly. For instance, after the following code. a = {} -- new array. for i=1, 1000 do. a[i] = 0.

In formal language theory and computer programming, string concatenation is the operation of joining two character strings end-to-end. For example, the concatenation of "snow" and "ball" is "snowball". —Wikipedia, Concatenation. The string concatenation operator in Lua is denoted by two dots ('..').
