Introduction Is Ring some sort of an improvement of PHP? List index start from 1 Philosophy behind data types in Ring Search of global names while defining the class attributes The documentation says functional programming is supported, but then this happens? What about predefined parameters or optional parameters in functions? What about the Boolean values in Ring? What are the advantages of using Ring over native C or C++? What are the advantages to using Ring over C# or Java? What are the advantages to using Ring over Lisp or Smalltalk? What are the advantages to using Ring over Python and Ruby? What are the advantages to using Ring over Tcl and Lua? What happens when we create a new object? What is the difference between Ring and Python? And is Ring Open Source? Where can I write a program and execute it? Which of 3 coding styles are commonly used or recommended by the community? Why I get Calling Function without definition Error? Why I get a strange result when printing nl with lists? Why Ring is not case-sensitive Why Ring uses 'See', 'Give', 'But' and 'Ok' Keywords? Why do we need Yet Another Programming Language (YAPL)? Why is Ring largely focussed on UI creation? Why is Ring weakly typed? Why setClickEvent() doesn't see the object methods directly? Why the Assignment operator uses Deep copy? Why the ability to define your own languages Instead of just handing over the syntax so you can parse it using whatever code you like? Why the window title bar is going outside the screen? Why this example use the GetChar() twice? Why we don't use () after the qApp class name? Why you can specify the number of loops you want to break out of? frFile() function FoxRing Functions Reference frFileToStr() function FoxRing Functions Reference frForceExt() function FoxRing Functions Reference frForcePath() function FoxRing Functions Reference frIIf() function FoxRing Functions Reference frInList() function FoxRing Functions Reference frInt() function FoxRing Functions Reference frJustDrive() function FoxRing Functions Reference frJustExt() function FoxRing Functions Reference frJustFName() function FoxRing Functions Reference frJustPath() function FoxRing Functions Reference frJustStem() function FoxRing Functions Reference frLen() function FoxRing Functions Reference frListToString() function FoxRing Functions Reference frLTrim() function FoxRing Functions Reference frPadL() function FoxRing Functions Reference frPadR() function FoxRing Functions Reference frProper() function FoxRing Functions Reference frReplicate() function FoxRing Functions Reference frRTrim() function FoxRing Functions Reference frSetIfEmpty() function FoxRing Functions Reference frSetSeparatorTo() function FoxRing Functions Reference frSpace() function FoxRing Functions Reference frStr() function FoxRing Functions Reference frStringToList() function FoxRing Functions Reference frStrTran() function FoxRing Functions Reference frStuff() function FoxRing Functions Reference frSubStr() function FoxRing Functions Reference frTransform() function FoxRing Functions Reference frVal() function FoxRing Functions Reference frVarType() function FoxRing Functions Reference Fseek() Files Fsetpos() Files FSize() Stdlib Functions Ftell() Files Function Prototype Extension function prototype Code Generator Function Structure Extension Functional Programming Anonymous and Nested Functions Equality of functions First-Class Functions Higher-order Functions Introduction Pure Functions Functions - First Style Call Functions Declare parameters Define Functions Introduction Main Function Recursion Return Value Send Parameters Variables Scope Functions - Second Style Call Functions Declare parameters Define Functions Introduction Main Function Recursion Return Value Send Parameters Variables Scope Functions - Third Style Call Functions Declare parameters Define Functions Introduction Main Function Recursion Return Value Send Parameters Variables Scope functions() Reflection and Meta-programming Fwrite() Files
