3. Ring Documentation, Release 1.10
8.3 New Tool: Ring2EXE
In Ring 1.6 we have a nice tool called Ring2EXE (Written in Ring itself)
Using Ring2EXE we can distribute applications quickly for Windows, Linux, macOS and Mobile devices
Read the chapter “Distributing Ring Applications using Ring2EXE” for more information!
8.4 Better Ring For Android
Ring For Android (using RingQt) is updated to use the Ring Object File ( *.ringo ) instead of using many source code
files ( *.ring )
The next screen shot is an example of building the cards game for Android
We are using cards.ringo instead of cards.ring
If you have large project (many *.ring files) it will use only one *.ringo file.
8.3. New Tool: Ring2EXE 90

4. Ring Documentation, Release 1.10
To prepare Qt project to distribute RingQt application for Mobile use Ring2EXE
Example
ring2exe cards.ring -dist -mobileqt
Example (2)
ring2exe formdesigner.ring -dist -mobileqt
8.4. Better Ring For Android 91

5. Ring Documentation, Release 1.10
8.5 New Tool: Folder2qrc
When we have large RingQt project that contains a lot of images and files, We need to add these files to the resource
file ( *.qrc ) when distributing applications for Mobile devices.
Instead of adding these files one by one, Ring 1.6 comes with a simple tool that save our time, It’s called Folder2qrc.
Example:
folder2qrc formdesigner.ring
We determine the main source file while we are in the application folder, and Folder2qrc will check all of the files in
the current folder and sub folders, Then add them to the resource file after the mainfile.ringo (In our example this will
be formdesigner.ringo)
The output file will be : project.qrc
You can open it and remove the files that you don’t need in the resources!
8.6 Better Scripts for building Ring
Ring 1.6 comes with better scripts for building Ring from source code.
The updates are tested on 32bit and 64bit systems on Windows, Linux (Ubuntu,Fedora) and macOS.
The scripts for Windows are updated to find the Visual C/C++ compiler based on your Visual Studio version.
8.7 RingConsoleColors Extension
Using the RingConsoleColors extension we can easily change the colors used in our console applications
For more information check the RingConsoleColors chapter in the documentation.
8.5. New Tool: Folder2qrc 92

6. Ring Documentation, Release 1.10
8.8 RingMurmurHash Extension
Ring 1.6 comes with the RingMurmurHash extension!
Developer: Hassan Ahmed
Example:
load "murmurhashlib.ring"
key = "Ring Language"
see murmurhash3_x86_32(key, 0, 0) + nl // Output: 1894444853
see murmurhash3_x86_32(key, 0, 1) + nl // Output: 70eaef35
For more information check the RingMurmurHash chapter in the documentation.
8.9 Better Ring Notepad
Ring Notepad comes with the next updates
1. Automatic setting for the Main File when we Run the application (using the Main file buttons).
2. Main File - Automatic save before running.
3. When we run GUI application - don’t change the focus to the text box used for the input in the Output Window.
4. A button and option to run web applications
For Windows users, Ring 1.6 comes with Apache Web server!
We can run any web application from any folder directly without doing any configuration.

2. Palindrome() function is updated (Return the output instead of printing it)
3. Using stdlibcore.ring we can use the StdLib functions (Without Classes)
Also this is useful when developing standalone console applications
Because using stdlib.ring (functions & classes) will load libraries like RingLibCurl, RingOpenSSL, etc.
4. New Functions
• SystemSilent(cCommand) Function : Execute system commands without displaying the output.
• OSCreateOpenFolder(cFolder) : Create folder then change the current folder to this new folder

8.14 Using Tab instead of char(9)
The variable Tab is defined to be used instead of char(9)
Example (1):
see :one + nl + tab + :two + nl + tab + tab + :three
Output:
one
two
three
You can change the variable to another value
Example (2):
tab = " "
see :one + nl + tab + :two + nl + tab + tab + :three
Output:
one
two
three
8.15 Using CR as Carriage return
The next example count from 1 to 10 in the same line during 10 seconds
load "stdlibcore.ring"
for x = 1 to 10 see x sleep(1) see cr next
8.16 Using the ! operator as not
We have = and != in the Ring language
But for the logical operators we have and, or & not
Now we can use the ! operator as not
Example:
if ! false
see "True!" + nl
ok
Output
True!
8.17 Using && and || operators
In Ring we have the next keywords for the logical operations
8.14. Using Tab instead of char(9) 97
