The document discusses different methods for distributing Ring applications, including: 1) Copying the Ring files and renaming the executable to distribute Windows applications. 2) Generating an object file from Ring code to protect the source code when distributing applications. 3) Using tools like NSIS to create Windows installers for applications. 4) Compiling Ring code with a C/C++ compiler and linker to create executable files. 5) Embedding Ring in Qt or LibSDL projects to build mobile apps and games for distribution.

FIFTYTHREE
DISTRIBUTING RING APPLICATIONS
In this chapter we will learn about distributing Ring applications.
53.1 Distributing Applications for Microsoft Windows
Step 1:
Copy c:ringbin folder to be for example c:myapp
Step 2:
Rename c:myappring.exe to c:myappmyapp.exe
Step 3:
Create a file c:myappring.ring
And write
Load "myapp.ring"
When you run myapp.exe the file ring.ring will be executed automatically
So your file myapp.ring will be called and executed
Or just rename myapp.ring to ring.ring
It’s a fast way to distribute applications.
53.2 Protecting the Source Code
Step 1:
Execute the next command
ring myapp.ring -go
This will generate one object file (myapp.ringo) from the project files (*.ring)
Step 2:
Rename myapp.ringo to ring.ringo
When you run the executable file (ring.exe) or (myapp.exe) the file ring.ringo will be executed.

53.3 Creating Windows Installer
There are many tools that you can use to distribute your application.
Check : nullsoft scriptable install system
URL : http://nsis.sourceforge.net/Main_Page
53.4 Using C/C++ Compiler and Linker
Another method to distribute applications is to use a C/C++ compiler.
Ring can be embedded in C/C++ projects, We can create executable files using a C/C++ compiler by embedding the
Ring language in our project.
Check the “Embedding Ring Language in C/C++ Programs” chapter.
Using this way we will avoid using ring.ring or ring.ringo files.
53.5 Distributing Applications and Games for Mobile
Ring can be embedded in a Qt projects or LibSDL projects to build Mobile applications and Games.
You can build the Qt project or the LibSDL project and get the Android package directly (*.apk)
Check Ring distributions for Mobile development using Qt or LibSDL.

COMMAND LINE OPTIONS
The ring language takes source code file (.ring) or the object file (.ringo) as input to execute, also the language provide
other options like
Option Description
-tokens Print a list of tokens in the source code file
-rules Print grammar rules applied on the tokens
-ic Print the intermediate byte code (before execution)
-icfinal Print the final byte code (after execution)
-cgi Print http response header before error messages
-norun Don’t run the program after compiling
-ins Print instruction operation code before execution
-performance Print clock before and after program execution
-go Generate Object File
-w Display Warnings
54.1 Printing Tokens
Example:
Func Main
See "Hello World" + nl
for x = 1 to 10
see x + nl
next
test()
func test
see "welcome" + nl
o1 = new point { x=10 y=20 z=30 }
see o1
class point x y z
Command:
ring test.ring -tokens -norun
Output:
