The document provides instructions for building and installing Ring, an open-source programming language, on different operating systems including Linux, MacOS, and using CMake. It describes how to build Ring's compiler/VM, extensions for networking, databases, graphics libraries, and more. Directions are given to generate source code for extensions like OpenGL and Qt. The document also covers installing Ring after building so it can be run from any folder.

6. CHAPTER
ELEVEN
GETTING STARTED - FIRST STYLE
11.1 Hello World
The next program prints the Hello World message on the screen (std-out).
see "Hello World"
11.2 Run the program
to run the program, save the code in a file, for example : hello.ring then from the command line or terminal, run it
using the ring interpreter
ring hello.ring
11.3 Not Case-Sensitive
Since the Ring language is not case-sensitive, the same program can be written in different styles
Tip: It’s better to select one style and use it in all of the program source code
SEE "Hello World"
See "Hello World"
11.4 Multi-Line literals
Using Ring we can write multi-line literal, see the next example
See "
Hello
Welcome to the Ring programming language
How are you?
"
Also you can use the nl constant to insert new line and you can use the + operator to concatenate strings
130

7. Ring Documentation, Release 1.5.4
Note: nl value means a new line and the actual codes that represent a newline is different between operating systems
See "Hello" + nl + "Welcome to the Ring programming language" +
nl + "How are you?"
11.5 Getting Input
You can get the input from the user using the give command
See "What is your name? "
Give cName
See "Hello " + cName
11.6 No Explicit End For Statements
You don’t need to use ‘;’ or press ENTER to separate statements. The previous program can be written in one line.
See "What is your name? " give cName see "Hello " + cName
11.7 Writing Comments
We can write one line comments and multi-line comments
The comment starts with # or //
Multi-lines comments are written between /* and */
/*
Program Name : My first program using Ring
Date : 2016.09.09
Author : Mahmoud Fayed
*/
See "What is your name? " # print message on screen
give cName # get input from the user
see "Hello " + cName # say hello!
// See "Bye!"
Note: Using // to comment a lines of code is just a code style.

Tip: It’s better to select one style and use it in all of the program source code
PUT "Hello World"
Put "Hello World"
12.4 Multi-Line literals
Using Ring we can write multi-line literal, see the next example
Put "
