a = one string b = string.gsub(a, one, another) -- change string parts print(a) --> one string print(b) --> another string Strings in Lua are subject to automatic memory management, like all Lua objects. That means that you do not have to worry about allocation and deallocation of strings; Lua handles this for you. A string may contain a single letter or an entire book. Lua handles long. Beispielprogramm print_4.lua print [[ Hallo Welt, wie schön bist du [[doch]] heute]] Das Ergebnis: Hallo Welt, wie schön bist du [[doch]] heute Verschachtelte Definitionen sind möglich, innere Zeichenketten werden übernommen.

Expanding on lhf's correct answer, the io library is preferred for production use.. The print function in the base library is implemented as a primitive capability. It allows for quick and dirty scripts that compute something and print an answer, with little control over its presentation. Its principle benefits are that it coerces all arguments to string and that it separates each argument in. s, e = string.find(hello Lua users, Lua) print(s, e) --> 7 9 Functions written in Lua also can return multiple results, by listing them all after the return keyword. For instance, a function to find the maximum element in an array can return both the maximum value and its location

The format string has rules similar to those of the printf function of standard C: It is composed of regular text and directives, which control where and how each argument must be placed in the formatted string. The Lua Reference says: The format string follows the same rules as the printf family of standar 3.4 - Concatenation Lua denotes the string concatenation operator by.

  1. In lua 5.1, you can iterate of the characters of a string this in a couple of ways. The basic loop would be: for i = 1, #str do local c = str:sub(i,i) -- do something with c en
  2. Remember that strings in Lua are immutable. The string.sub function, like any other function in Lua, does not change the value of a string, but returns a new string. A common mistake is to write something like string.sub(s, 2, -2) and to assume that the value of s will be modified. If you want to modify the value of a variable, you must assign the new value to the variable: s = string.sub(s, 2.

This library provides generic functions for string manipulation, such as finding and extracting substrings, and pattern matching.

So in the pattern .*%S , it takes all characters until the last non-space The Lua language provides numerous built-in methods that your program can call.

Strings, are in essence, a table of ordered characters (Known as a Character Array) with a terminating character ('\\0') at the end. In older programming languages, to declare a string you would first have to create a character list, then create a string class and pass the character list to it. In lua, though, all of this is done at run-time so you can directly assign and minipulate strings.

String interpolation in Lua. Lua is known for having a very lean standard library, and for providing mechanisms to do things instead of a ton of features. String interpolation isn't available out of the box, but doing it in Lua isn't a new trick. In fact, the manual includes it as an example of string.gsub Lua is a programming language designed primarily for embedded systems. It is popular in the video game industry as a language that can be embedded in a larger game engine.

Overview. The Corona string library provides generic functions for string manipulation, such as pattern matching and finding/extracting substrings. When indexing a string in Lua, the first character is at position 1, not at position 0 as in C. Indices are allowed to be negative and are interpreted as indexing backwards from the end of the string You can find details about the string library in section 5.4 of the Reference Manual .For practical examples of usage of the string library, have a look at StringRecipes.. Note: In Lua string indices start at index value 1, not index value 0 (as they do in C).. string.byte(s [, i [, j]]
