Version 1.0.2

Version 1.0.1

Version 1.0.0

Version 1.0.0rc1

  • 24 Jul 2018
  • fixed TObject.Create()
  • -vd shows stacktraces

Version 0.9.32

  • 17 Jul 2018
  • fixed memory leaks and double frees

Version 0.9.31

  • 10 Jul 2018
  • fixed aIntSet:=[0]
  • fixed crash on List.Items.Dummy
  • fixed some mem leaks
  • fixed -MDelphi + $mode objfpc + overloads withouts overload keyword

Version 0.9.30

  • 4 Jul 2018
  • fixed calling COM interface _Release function for expressions.
  • fixed catching exception in pju variant of pas2js
  • split reserved words into two categories: the compiler now checks global JS identifiers like "Date" only for identifiers without path. That means a local variable Date will be renamed, a property Date will not, keeping the RTTI name of properties. Identifiers like apply are still renamed.
  • fixed property RTTI for alias type in other unit
  • fixed default value of integer variables, using 0 even if it is outside range. Reason: Delphi/FPC compatibility.

Version 0.9.29

  • 29 Jun 2018
  • fixed pcu reading alias type
  • fixed analyzer: element needing typeinfo marks indirect elements as used normally
  • hint for text after final "end.", disable with $warn GARBAGE off
  • $warn BOUNDS_ERROR off: disable range check warnings at compile time
  • $warn MESSAGE_DIRECTIVE off: disable $message notes

Version 0.9.28

  • 27 Jun 2018
  • fixed static array of char = stringlit+stringlit
  • fixed libpas2js disk full error
  • $warn directive: {$warn identifier on|off|default|error}, identifier can be a message number as shown with -vq or one of the following. Note, that some hints like "Parameter %s not used" are currently using the enable state at the end of the module, not the state at the hint source position.
    • CONSTRUCTING_ABSTRACT: Constructing an instance of a class with abstract methods.
    • IMPLICIT_VARIANTS: Implicit use of the variants unit.
    • NO_RETVAL: Function result is not set
    • SYMBOL_DEPRECATED: Deprecated symbol
    • SYMBOL_EXPERIMENTAL: Experimental symbol
    • SYMBOL_LIBRARY
    • SYMBOL_PLATFORM: Platform-dependent symbol
    • SYMBOL_UNIMPLEMENTED: Unimplemented symbol
    • HIDDEN_VIRTUAL: method hides virtual method of ancestor

  • typecast function reference to JS function, e.g. TJSFunction(OnClick)
  • typecast method address to JS function, e.g. TJSFunction(@List.Sort). Note that a method address creates a function wrapper to bind the Self argument.
  • changed some types to type alias: TDateTime, TDate, TTime, Single, Real, Comp, UnicodeString, WideString. This only effects typinfo and some compiler error messages. Reason: Delphi/FPC compatibility.
  • In mode delphi dynamic array initializations must now use square brackets instead of round brackets. For example var a: array of integer = [1,2];. Reason: Delphi compatibility.
  • Assignation using constant array. For instance Arr:=[1,2,3], where Arr is a dynamic array.
  • + operator for arrays: This concatenation operator is available using the new modeswitch arrayoperators, which is enabled by default in mode delphi.

    • 4501 for virtual/override methods
    • 5024 for others

Version 0.9.25

  • 7 Jun 2018
  • TComponent now supports IInterface

  • allow typecast array to TJSObject
  • allow typecast TJSObject to array
  • Unicode character constants outside of BMP, e.g. #$10437
  • allow {$H+}, error on {$H-}

  • 2 May 2018
  • type alias type, e.g. type TCaption = type string;
  • record const, e.g. const p: TPoint = (x:1; y:2);
  • {$WriteableConst on|off}: treat typed constants as readonly, e.g. const i:byte=3;... i:=4; creates a compile time error.
  • forbid assignment of for-loop variable
  • nested classes
  • property specifier nodefault
  • default(type) returning the initial value of the type, e.g. default(recordtype).

  • Fix initializing next buffers in TDataset.
  • Implemented Currency as double, values are multiplied by 10000 and truncated, so a 2.7 is stored as 27000.
  • Implemented pointer of record. It's simply a reference.
    • p:=@r translates to p=r
    • p^.x becomes p.x
    • intrinsics new(PointerOfRecord), dispose(PointerOfRecord). dispose(p) sets p to null if possible.
  • enumerator for jsvalue: e.g. var v: jsvalue; key: string; for key in jsvalue do translates to for (key in jsvalue){}

  • case-of statement: error on duplicate values
  • fixed error on int:=double

Version 0.9.16

  • implemented class interfaces:
    • methods, properties, default property
    • {$interfaces com|corba|default}
      • COM is default, default ancestor is IUnknown (mode delphi: IInterface), managed type, i.e. automatically reference counted via _AddRef, _Release, the checks for support call QueryInterface
      • CORBA: lightweight, no automatic reference counting, no default ancestor, fast support checks.
    • inheriting
    • GUIDs are simple string literals, TGUID = string.
    • An interface without a GUID gets one autogenerated from its name and method names.
    • a class implementing an interface must not be external
    • a ClassType "supports" an interface, if it itself or one of its ancestors implements the interface. It does not automatically support an ancestor of the interface.
    • method resolution, procedure IUnknown._AddRef = IncRef;
    • delegation: property Name: interface|class read Field|Getter implements AnInterface;
    • is-operator:
      • IntfVar is IntfType - types must be releated

      • ObjVar is IntfType - can be unrelated
    • as-operator
      • IntfVar as IntfType - types must be releated
      • IntfVar as ClassType - types can be unrelated, nil returns nil, invalid raises EInvalidCast
      • ObjVar as IntfType - mode delphi: types must be related, objfpc: can be unrelated, nil if not found, COM: uses _AddRef
    • typecast:
      • IntfType(IntfVar) - must be related
      • ClassType(IntfVar) - can be unrelated, nil if invalid
      • IntfType(ObjVar) - mode delphi: must be related, objfpc: can be unrelated, nil if not found, COM: if ObjVar has delegate uses _AddRef
      • TJSObject(intfvar)
    • Assign operator:
      • IntfVar:=nil
      • IntfVar:=IntfVar2 - IntfVar2 must be same type or a descendant
      • IntfVar:=ObjVar - nil if unsupported
      • jsvalue:=IntfVar
    • Assigned(IntfVar)
    • RTTI
    • $modeswitch ignoreinterfaces was removed
    • Not supported: array of interface, interface as record member

Version 0.8.16

  • 28 Jul 2017
  • bugfix release.

Version 0.8.15

  • 8 Jul 2017
  • compiler can now generate source maps when passing option -Jm

Version 0.8.14

  • 17 May 2017
  • now supports TObject.Free.

In Delphi/FPC obj.Free works even if obj is nil. In JavaScript this would crash. And to free memory JS requires to clear all references, which is not required in Delphi/FPC. Therefore the compiler adds code to check for null, call the destructor and sets the variable to null.

It does not support freeing properties and function results. For example: List[i].Free; will give a compiler error. The property setter might create side effects, which would be incompatible to Delphi/FPC.

Version 0.8.13

  • 11 May 2017
  • $IF
  • $ELSEIF
  • $IFOPT
  • $Error
  • $Warning,

Version 0.8.12

  • 5 May 2017
  • dotted unit names and namespaces.

Version 0.8.11

  • 23 Apr 2017
  • dynamic arrays can now be initialized with a constant. Same syntax as static arrays: const a: array of string = ('one', 'two');
  • Classes can now be declared in the unit implementation.
  • Unit nodejs now has a console class TNJSConsole.
  • I added the fpcunit package. Successful tests already work. A fail is not yet caught.

Version 0.8.10

  • you can now use "if aJSValue then", which works just like the JS "if(v)".
  • added ParamCount, ParamStr, GetEnvironment* functions. The default is not doing much.
  • new package fcl_base_pas2js, containing custapp and nodejsapp: - TCustomApplication is the known class from the FCL, but with abstract methods.
  • TNodeJSApplication is a TCustomApplication using nodejs to read command line params and environment variables.

Version 0.8.9

  • 21 Apr 2017
  • The compiler now has the types 53bit NativeInt and 52bit NativeUInt. Keep in mind that there is still no range checking.

Current aliases:

  JSInteger = NativeInt;

  Integer = LongInt;
  Cardinal = LongWord;
  SizeInt = NativeInt;
  SizeUInt = NativeUInt;
  PtrInt = NativeInt;
  PtrUInt = NativeUInt;
  ValSInt = NativeInt;
  ValUInt = NativeUInt;
  ValReal = Double;
  Real = Double;
  Extended = Double;

  Int64 = NativeInt unimplemented;
  QWord = NativeUInt unimplemented;
  Single = Double unimplemented;
  Comp = Int64 unimplemented;

  UnicodeString = String;
  WideString = String;
  WideChar = char;

Version 0.8.8

  • 20 Apr 2017
  • bugfix release.

Version 0.8.7

  • 18 Apr 2017
  • $mod: the current module
  • Self: in a method with nested functions this holds the class or class instance.
  • overloads are now chosen like FPC/Delphi not only by type, but also by precision. This means if there are several compatible overloads, and none fits exactly it will choose the next higher. Formerly it gave an error.
  • cardinal is no longer a base type, but longword is. Same as FPC.

Version 0.8.6

  • 17 Apr 2017
  • bugfix release.

Version 0.8.5

  • indexed properties for external classes.

Version 0.8.4

  • 14 Apr 2017
  • bugfix release.

Version 0.8.3

  • 4 Apr 2017
  • pas2js now has code navigation in Lazarus

Trunk

  • added variable rtl.version, which correspond to the compiler version Major*10000+Minor*100+Release
  • added option -JoCheckVersion:
    • -JoCheckVersion- : do not add rtl version check, default.
    • -JoCheckVersion=main : insert rtl.checkVersion() into main.
    • -JoCheckVersion=system : insert rtl.checkVersion() into system unit.
    • -JoCheckVersion=unit : insert rtl.checkVersion() into every unit.
  • moved classtopas function to a class2pas unit, improved the interface so it uses a stringlist. Adapted the demo.
  • Fix System.Int() so it also works on IE (where Math.trunc is missing).
  • allow typecasting string(apointer) and pointer(astring)
  • asm-blocks now skips Pascal comments //... and Pascal string literals with single quotes. It no longer stops at end in such comments and string literals.
  • Fix FormatFloat() rounding logic (actually FloatToDecimal)
  • Fix stringofchar for count<=0
  • Fix quotestring and add quotedstr
  • implemented special includes like {$i %date%}:
    • %date%: current date as string literal, '[yyyy/mm/dd]'
    • %time%: current time as string literal, 'hh:mm:ss'
    • %line%: current source line number as string literal, e.g. '123'
    • %currentroutine%: name of current routine as string literal
    • %pas2jstarget%, %pas2jstargetos%, %fpctarget%, %fpctargetos%: target os as string literal, e.g. 'Browser'
    • %pas2jstargetcpu%, %fpctargetcpu%: target cpu as string literal, e.g. 'ECMAScript5'
    • %pas2jsversion%, %fpcversion%: compiler version as strnig literal, e.g. '1.0.2'
  • implemented pred(char), succ(char)
  • allow typecasting TypedPointer(UntypedPointer)
  • allow assign UntypedPointer:=TypedPointer
