Pas2JS Version Changes

Version 0.8.41

Version 0.8.41 supports enumerators:

• ordinal types: char, boolean, byte, ..., longword, enums, sets, static array, custom range
• const set
• variables: set, string, array
• class GetEnumerator

It does not support operator enumerator, IEnumerator, member modifier enumerator.

Version 0.8.40

• File read callback for pas2jslib

Version 0.8.39

• fixed circular unit dependencies

Version 0.8.38

• support for * and ? in search paths
• fixed converting a typecast to an alias proc type
• fixed inherited-identifier-as-expr
• emit warning method-hides-method-in-base-type only for virtual methods
• reduced function hides identifier from level hint to info
• fixed unit contnrs to always use mode objfpc.

Version 0.8.37

• Bugfixed a combination of overload/override

Version 0.8.36

• fixed missing brackets in binary expression and left side has a call (a-f(b)) / (c-d)

Version 0.8.35

• fixed a bug in the overload code

Version 0.8.34

• fixed skipping attributes behind procedure declarations.
• Procedures/methods now properly hides procs with same name.
• In mode delphi overloads now always require the 'overload' modifier.
• In mode objfpc the modifier is required when using different scopes.
• hints for hiding identifiers of other units.
• implemented system.built-in-identifier.

Version 0.8.33

• srcmaps with included sources now ignores untranslatable local paths and simply uses the full local path.
• custom enum ranges, e.g. TBlobType = ftBlob..ftBla
• custom integer ranges, e.g. TSome = 1..5
• custom char ranges
• set of custom enum/integer/char ranges
• the conversion of the for-to-do loop has changed. If the loop is never executed, the loop variable is not touched. And the start expression is now executed before the end expression.

Version 0.8.32

• some bug fixes for warnings

Version 0.8.31

• bugfix for implicit function calls of parameters of some built in functions.

Version 0.8.30

• nicer "can't find unit" position
• fixed a crash parsing uses clause

Version 0.8.29

• bugfixes
• it now supports directive $M alias $TypeInfo

Version 0.8.28

• fixed passing static array

Version 0.8.27

• implemented resourcestrings
• implemented logical xor
• fixed class-of-typealias
• fixed property index modifier expression

Version 0.8.26

• fixed RTTI for static arrays
• implemented property modifier index
• implemented FuncName:=

Version 0.8.25

• bugfixes
• a new modeswitch ignoreattributes to ignore attributes.

Version 0.8.24

• implemented multi dimensional SetLength
• fixed keeping old values when using SetLength
• fixed method override of override

Version 0.8.23

• property default value for sets
• custom integer ranges, like TValueRelationship
• typecast enums to integer type (same as ord function)
• new modeswitch ignoreinterfaces to parse class interfaces, but neither resolve nor convert them. Using them will cause an error.

Version 0.8.22

• fixed loading dotted units
• implemented property stored and default modifiers

Version 0.8.21

• fixed aString[index]:=
• fixed analyzer to mark default values of arguments
• many improvements for sourcemaps making step-over/into nicer in Chrome.
• new tool fpc/packages/fcl-js/examples/srcmapdump to dump the produced sourcemap.
• unicodestring and widechar are now declared by the compiler instead of system.pas

Version 0.8.20

• Static array const are now implemented. For example:
• array['a'..'d'] of integer = (1,2,3,4);
• array[1..3] of char = 'pas';

Version 0.8.19

• several bug fixes
• started static arrays:
  • array[2..6] of char
  • array['a'..'z'] of char
  • array[boolean] of longint
  • array[byte] of string
  • array[enum] of longint
  • array[char] of boolean // Note that char is widechar!
  • low(), high()

Version 0.8.18

Anonymous arrays in record members are now supported:

  TFloatRec = Record
     ...
     Digits: Array Of Char;
  End;

Version 0.8.17

• checks for semicolons between statements
• fixed proc type of procedure in Delphi mode
• implemented @@ operator for proc types in Delphi mode.
• compile time evaluation, range and overflow checking for boolean, base integer types, enums, sets, custom integer ranges, char, widechar, string, single and double.

Version 0.8.16

• bugfix release.

Version 0.8.15

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

Version 0.8.14

• 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.
