What is new in Ring 1.3?¶
In this chapter we will learn about the changes and new features in Ring 1.3 release.
List of changes and new features¶
Ring 1.3 comes with many new features
- Better RingQt
- Better Ring Notepad
- Ring mode for Emacs Editor
- Better StdLib
- Better Loop/Exit Command
- New Functions
- Return Self by Reference
- Using ‘<’ and ‘:’ operators as ‘from’ keyword
- Embedding Ring in Ring without sharing the State
- RingZip Library
- Form Designer
Better RingQt¶
(1) Another version of QPixMap class is added (QPixMap2) which takes (int width,int height) during object init.
Example:
Load "guilib.ring"
New qapp
{
win1 = new qwidget()
{
setwindowtitle("Drawing using QPixMap")
setgeometry(100,100,500,500)
label1 = new qlabel(win1)
{
setgeometry(10,10,400,400)
settext("")
}
imageStock = new qlabel(win1)
{
image = new qPixMap2(200,200)
color = new qcolor() {
setrgb(255,255,255,255)
}
pen = new qpen() {
setcolor(color)
setwidth(10)
}
new qpainter() {
begin(image)
setpen(pen)
drawline(0,0,200,200)
drawline(200,0,0,200)
endpaint()
}
setpixmap(image)
}
show()
}
exec()
}
Screen Shot:
- The Objects Library is updated to include the next functions
- Last_WindowID()
- Open_WindowNoShow()
- Open_WindowAndLink()
Also the class name (WindowViewBase) is changed to (WindowsViewParent).
In The next code for example the Open_WindowAndLink() will create an object from the SecondWindowController Class Then will add the Method SecondWindow() to the FirstWindowController Class Also will add the Method FirstWindow() to the SecondWindowController Class
So the SendMessage() method in FirstWindowController class can use the SecondWindow() method to access the object.
class firstwindowController from windowsControllerParent
oView = new firstwindowView
func OpenSecondWindow
Open_WindowAndLink(:SecondWindowController,self)
func SendMessage
if IsSecondWindow()
SecondWindow().setMessage("Message from the first window")
ok
func setMessage cMessage
oView.Label1.setText(cMessage)
- The next classes are added to RingQt
- QPixMap2
- QScrollArea
- QSplitter
- QCompleter
- QCompleter2
- QCompleter3
- QProcess
- QMdiArea
- QMdiSubWindow
- QCursor
- QListView
- QDesktopServices
- Many constants are defined in qt.rh (loaded by guilib.ring)
- New Classes names - Index Start from 1
We added new classes to RingQt - another version of classes where the class names doesn’t start with the “q” letter Also updated methods so the index start from 1 when we deal with the GUI controls like
- ComboBox
- ListWidget
- TableWidget
- TreeWidget
These classes are inside guilib.ring under the package name : System.GUI
To use it
load "guilib.ring"
import System.GUI
This doesn’t have any effect on our previous code, It’s just another choice for better code that is consistent with Ring rules.
Also the form designer is updated to provide us the choice between using classes where (index start from 0) or (index start from 1)
Example (Uses the Form Designer)
Better Ring Notepad¶
- Using QPlainTextEdit instead of QTextEdit
- Displaying the line number for each line in the source code file.
Screen Shot:
- Auto-Complete for Ring functions names, classes and words in the opened file.
- Functions and Methods List
- Output Window
- Classes List
- Change the Current Style
Better StdLib¶
The StdLib is updated to include the next functions
- SplitMany()
- JustFilePath()
- JustFileName()
Better Loop|Exit Command¶
The Loop|Exit command is updated to accept Expressions after the command (not only numbers).
The syntax:
Loop|Exit [Number]
Changed to
Loop|Exit [Expression]
Example
XLoop = 2 # The outer loop
YLoop = 1 # The first inner loop
for x = 1 to 10
for y = 1 to 10
see "x=" + x + " y=" + y + nl
if x = 3 and y = 5
exit XLoop
ok
next
next
New Functions¶
- PackageName() function
- Swap() function
Example:
aList = [:one,:two,:four,:three]
see aList
see copy("*",50) + nl
swap(aList,3,4)
see aList
Output
one
two
four
three
**************************************************
one
two
three
four
Return Self by Reference¶
In this release, using Return Self in class methods will return the object by reference.
Example:
mylist = [new mytest() {
see self
x = 20
see self
}]
see mylist
class mytest
x = 15
func init
return self # Return by reference
Output
x: 15.000000
x: 20.000000
x: 20.000000
Using ‘<’ and ‘:’ operators as ‘from’ keyword¶
In this release of the Ring language we can use the ‘<’ and ‘:’ operators as the ‘from’ keyword
Syntax (1):
class Cat from Animal
Syntax (2):
class Cat < Animal
Syntax (3):
class Cat : Animal
Embedding Ring in Ring without sharing the State¶
From Ring 1.0 we already have functions for embedding Ring in the C language. Also we can execute Ring code inside Ring programs using the eval() function. In this release we provide functions for embedding Ring in Ring programs without sharing the state.
Advantages:
- Quick integration for Ring programs and applications together without conflicts.
- Execute and run Ring code in safe environments that we can trace.
Example:
pState = ring_state_init()
ring_state_runcode(pState,"See 'Hello, World!'+nl")
ring_state_runcode(pState,"x = 10")
pState2 = ring_state_init()
ring_state_runcode(pState2,"See 'Hello, World!'+nl")
ring_state_runcode(pState2,"x = 20")
ring_state_runcode(pState,"see x +nl")
ring_state_runcode(pState2,"see x +nl")
v1 = ring_state_findvar(pState,"x")
v2 = ring_state_findvar(pState2,"x")
see v1[3] + nl
see V2[3] + nl
ring_state_delete(pState)
ring_state_delete(pState2)
Output:
Hello, World!
Hello, World!
10
20
10
20
RingZip Library¶
Ring 1.3 comes with the RingZip library for creating, modifying and extracting *.zip files.
Example (1): Create myfile.zip contains 4 files
load "ziplib.ring"
oZip = zip_openfile("myfile.zip",'w')
zip_addfile(oZip,"test.c")
zip_addfile(oZip,"zip.c")
zip_addfile(oZip,"zip.h")
zip_addfile(oZip,"miniz.h")
zip_close(oZip)
Example (2): Extract myfile.zip to myfolder folder.
load "ziplib.ring"
zip_extract_allfiles("myfile.zip","myfolder")
Example (3): Print file names in the myfile.zip
load "ziplib.ring"
oZip = zip_openfile("myfile.zip",'r')
for x=1 to zip_filescount(oZip)
see zip_getfilenamebyindex(oZip,x) + nl
next
zip_close(oZip)
Example (4) : Using Classes instead of Functions
load "ziplib.ring"
new Zip {
SetFileName("myfile.zip")
Open("w")
AddFile("test.c")
AddFile("zip.c")
AddFile("zip.h")
AddFile("miniz.h")
Close()
}
Form Designer¶
Ring 1.3 comes with the Form Designer to quickly design your GUI application windows/forms and generate the Ring source code.
It’s written in Ring (Around 8000 Lines of code) using Object-Oriented Programming and Meta-Programming.
We can run the From Designer from Ring Notepad
Also we can run the Form Designer in another window.

Statistics
Opencast provides an extensible mechanism to make statistics data available to the Opencast administrative user interface and also to third-party applications using the External API.
The overall idea is that sources of statistics data (StatisticsProvider) are managed at a central service (StatisticsService). The StatisticsService supports a minimal set of common attributes, in particular, the type of the StatisticsProvider which implies a data format and available parametrization.
A client can use the StatisticsService to retrieve a list of all available StatisticsProviders. The data format as well as the parameters supported by the StatisticsProviders are implied by the type of the provider. This information is used by the client to decide whether it can visualize the statistics data and which component has to be used for visualization.
Modules
The StatisticsService consists of the following modules:
statistics-service-api
An API module defining the core StatisticsService and StatisticsProvider functions.statistics-service-impl
The default implementation of the StatisticsService as an OSGi service.statistics-service remote
The remote implementation of the StatisticsService.statistics-provider-influx
An implementation of the StatisticsProvider for InfluxDBstatistics-provider-random
An implementation of the StatisticsProvider for testing and demo purposes.
Interfaces & Classes
The Opencast StatisticsService
implements the two interfaces StatisticsCoordinator
and
StatisticsService.
StatisticsCoordinator
This interface is used by StatisticsProvider
implementations to register and unregister themselves at the
statistics service.
| Method | Description |
|---|---|
| addProvider | Register a statistics provider at the statistics service |
| removeProvider | Unregister a statistics provider from the statistics service |
StatisticsService
This is the interface used by clients of the statistics service to retrieve a list of registered statistics providers
| Method | Description |
|---|---|
| getProviders | Retrieve lists of statistics providers |
StatisticsProvider
The StatisticsProvider
interface provides access to common attributes of the statistics providers:
| Method | Description |
|---|---|
| getId | Returns the unique identifier of the statistics provider |
| getType | Returns the type of the statistics provider |
| getResourceType | Returns the ResourceType of the statistics provider |
| getName | Returns the displayable name of the statistics provider |
| getDescription | Returns the displayable description of the statistics provider |
whereas supported resource types are
| ResourceType | Description |
|---|---|
| EPISODE | The statistics data relates to an episode |
| SERIES | The statistics data relates to a series |
| ORGANIZATION | The statistics data does not relate to a particular object |
Integration
The StatisticsService API is supposed to be an internal Opencast interface. External clients can use the External API to access Opencast statistics and the Opencast Admin UI has access through the Admin UI facade.
External API
The External API supports Opencast statistics by its Statistics API endpoint.
Admin UI
The Admin UI supports Opencast statistics at various levels:
| File | Description |
|---|---|
| modules/admin-ui/src/main/java/org/opencastproject/adminui/endpoint/StatisticsEndpoint.java | Implementation of the Statistics endpoint for the Admin UI facade |
| modules/admin-ui/src/main/webapp/scripts/shared/resources/statisticsResource.js | Abstracts StatisticsEndpoint for use in the web application |

Recommendations: Great Unknown Movies Copyright 1987 by Steve Upstill
Speaking of unknown great movies, here is a short list of unknown/forgotten films that populate my all-time-favorite list.
Face in the Crowd (1957) -- The writer-director team of the earlier Marlon Brando classic "On The Waterfront" collaborated on this melodrama of a bum from the South who gets on the radio and becomes what is now known as a media celebrity in the early days of television. Andy Griffith, of all people, turns in one of the most galvanizing performances you'll ever see. Turn off the lights, watch it all at once and be stunned.
The Tenant (1976) -- Roman Polanski's existential horror film about a man with a shaky lease on his own soul. Polish immigrant in Paris (Polanski) takes the apartment of a woman who hasn't quite committed suicide. The clearest example I know of Polanski's greatness as a filmmaker, this film can be seen as three or four independent great films: as straightforward mystical horror; as creepy, blackest comedy; as a depiction of existential detachment along the lines of Polanski's earlier "Repulsion"; as a brutal examination of human vampirism. Again, you have to pay full attention to get the full impact, but under the right conditions this one will have you raving for days.
McCabe and Mrs. Miller (1971) -- Robert Altman's first film after the celebrity afforded him by M*A*S*H wasn't entirely ignored, but neither does it have nearly the regard it deserves. Possibly the first "revisionist Western," it's an exquisite mood piece exactly like a Leonard Cohen song -- and a number of those appear on the soundtrack. Warren Beatty plays a gunfighter attempting to retire to a dingy mining town running a whorehouse. Or rather, getting Julie Christie to run it for him. This is a classic for illustrating the magic of cinema, as all the scenes and small bits add up to a deeply moving, melancholy finale.
Breaker Morant (1981) -- again, hardly an unknown (it enjoyed a sweep of the Australian Academy Awards), this is a courtroom drama and a moral examination of stunning perfection. "Breaker" Morant is an Australian officer in the Boer wars in South Africa brought up on war-crimes charges by British officials in search of a scapegoat. It is first a riveting courtroom drama as the attorneys for Morant struggle to overcome the system. But it is also about moral ambiguity, personal responsibility and colonial exploitation (of the Australians as well as the South Africans by the British), recalling implicitly such historic tragedies as the Holocaust and the war in Vietnam. But the show's the thing -- it isn't every day that you have to tear your eyes away from a film and forcibly remind yourself that what you're seeing is really just a movie.
Sullivan's Travels (1943) Miracle of Morgan's Creek (1941) -- the seven or eight movies made by Preston Sturges between 1939 and 1944 (other highlights are "Hail the Conquering Hero," "Palm Beach Story," the original "Unfaithfully Yours" and "The Lady Eve") are as unrecognized a set of national movie treasures as I could name. No one before or since has combined snappy wordplay, low slapstick, loony characterizations, hurtling plots, arch social commentary (especially regarding the then-sacred small-town America) and sure-handed direction in such tight packages. "Miracle at Morgan's Creek" is both the wildest of his comedies and the most cutting -- the plot concerns a small-town girl who marries and gets pregnant by one of the five soldiers ("Oh I don't know -- it was something like...Ratskiwatsky") she goes out with one night before they ship out to Europe. "Sullivan's Travels" is Sturges' masterpiece, at once a self-defense for doing comedy in a grim world, a satire of socially-conscious filmmaking, and a moving picture of the suffering comedy relieves. If that sounds like an odd mix, then you get an idea of the miracle that Sturges pulls off here. The ease and sure-footedness with which he switches from broad comedy to tragedy, again and again, will make you gasp.

I Want A God Fearing Man Who Will Share Scriptures With Me On Daily Basis – YaaYaa Reveals
by vanessa nordziEvery woman has a type of man she would date or marry and men equally have a type of women they’d like to date or marry. Some women want tall dark men, others want rich men and the list goes on s on. Ghanaian musician Yaa Yaa has presented a checklist for the kind of man she would consider for a relationship/ marriage.
According to YaaYaa, her ideal man must be God-fearing and prayerful. She wants a man who will share scriptures with her on daily basis.
“Everyone thinks I have a boyfriend but I don’t. I want a God-fearing man who prays often and can share the scriptures with me,” YaaYaa told Andy Dosty on the Daybreak Hitz.
YaaYaa who was in the studio to promote her new song titled “E be money” , further explained that, when it comes to her ideal man, she doesn’t care about his complexion or height, as long as he is God- fearing and prayerful.
” My ideal man’s complexion or height doesn’t matter that much to me. He must be a Christian and prayerful.” She reiterated.
