Title: Pas2JS Version Changes

New		Line
1	+	# Releases
2	+
3	+	## Next Version
4	+
5	+	- Fixed precedence multiply and power: 100 9 ** 0.5* results in 100 (9 ** 0.5)*
6	+	- Fixed Delphi style multiline string literals containing apostrophs.
7	+
8	+	## 3.0.1
9	+
10	+	27th Feb 2024
11	+
12	+	Changes:
13	+
14	+	- New download server for the precompiled binaries: <https://getpas2js.freepascal.org>
15	+	- Namespaces (unitnames with dotted prefixes):
16	+	- added compiler option -FN\<X\>: add \<x\> to namespaces. Namespaces with trailing - are removed. Delphi calls this flag "unit scope names".
17	+	- The packages were extended to support namespaced version of units, e.g. units in packages/rtl are now in packages/rtl/src and the namespaced versions are in packages/rtl/namespaced
18	+	- This requires updating the -Fu paths in your pas2js.cfg, see [[pas2js.cfg\|pas2js.cfg Example]]
19	+	- Removed submodule "compiler" and instead support "compiler" as copy, symlink or FPCDIR environment variable. See [[pas2js\|Fetching pas2js source via git and compile]]
20	+	- Many external JS classes updated and extended
21	+	- FPC Wasm code can access the DOM and JS APIs through pas2js code: [[WebAssembly/DOM]]
22	+	- fixed marking library export function result sub elements as used
23	+	- fixed parsing var section after class var section
24	+	- fixed names of properties MultilineStringsTrimLeft and MultilineStringsEOLStyle
25	+	- fixed multilinestrings:
26	+	- combos like \`abc\`#10
27	+	- double backticks become, same as double apostrophs become one in string literals
28	+	- apostroph
29	+	- fixed anonymous procedure type
30	+	- fixed anonymous record type
31	+	- fixed searching TJSPromise in global scopes, while context is a dot scope
32	+	- fixed typecast array literal to TJSArray
33	+	- added releasecreator, tool written in fpc to compile the compiler and tools
34	+	- Support for datamodules in resources
35	+	- Tool to import typescript declaration modules as external classes
36	+	- Split Web unit into units usable in service workers and main browser window.
37	+	- Many updates on the widgets, support for bulma-styled widgets
38	+	- JSONRPC client support and tool to generate import based on ExtJS-styled API.
39	+	- Add Debugcapture to send logging to server
40	+	- Add testinsight client.
41	+
42	+	### 3.0.1 Incompatibilities
43	+
44	+	### Unitpaths of default packages in pas2js.cfg
45	+
46	+	- The default packages source paths have changed namespaced versions were added.
47	+	- Remedy: Update the -Fu paths in your pas2js.cfg, see [[pas2js.cfg\|pas2js.cfg Example]]

173	+	- added separate hints 4501 field "x" not used and 4502 field "x" assigned but never used. Delphi/FPC do not have these hints, as they treat records as one memory block and can't omit fields. pas2js can omit fields.
174	+	- The param in await(param) must now be an async function, to avoid accidentally calling the wrong function or not a function at all.

248	+
249	+	5th Nov 2020
250	+
251	+	## All changes of version 2.0.0
252	+
253	+	- the binary snapshots now use same directories as "make all". E.g. bin\i386-win32 for the Windows 32bit executables.
254	+	- [[pas2js Generics\|Generics]]
255	+	- Attributes:
256	+	- Incompatibility: \$modeswitch ignoreattributes was removed
257	+	- base class System.TCustomAttribute
258	+	- \$modeswitch prefixedattributes: enabled by default in \$mode Delphi
259	+	- declare in front of any type, type member
260	+	- the Delphi compiler attributes like ref, weak, volatile, etc are not supported.
261	+	- query attributes of a type:
262	+	- use either typinfo function GetRTTIAttributes(typeinfo(SomeType).Attributes):
263	+	- or use RTTI unit r:=TRTTIContext, r.GetType(typeinfo(SomeType)).GetAttributes
264	+	- class constructors:
265	+	- for classes, records, class helpers, record helpers and type helpers.
266	+	- Called in initialization section
267	+	- Optimizer removes attributes if type is not used.
268	+	- VarArg.Free, e.g. procedure DoIt(var Arg: TObject); begin Arg.Free end; setting Arg to nil
269	+	- range checking for type helpers
270	+	- range checking for var/out arguments
271	+	- fixed low/high(nativeint) for 53 significand bits instead of only 52 explicit bits, increasing high to \$1fffffffffffff = 9007199254740991
272	+	- float literal: removing unneeded 0 in front of E e.g. 1.20E1 as 1.2E1
273	+	- Overflow checks for integers -Co {\$overflowchecks on} {\$Q+} for integer operators +, -, *. Checks if result is outside nativeint and raises EIntOverflow.
274	+	- class abstract modifier
275	+	- type helper for classtype, same as FPC
276	+	- type helper for interfacetype, no constructors, same as FPC
277	+	- Dispatch messages:
278	+	- method modifier message integer and message string
279	+	- directive {\$DispatchField fieldname} and {\$DispatchStrField fieldname}
280	+
281	+	Insert these directives in front of your dispatch methods to let the compiler check all methods with message modifiers if they pass a record with the right field.
282	+
283	+	``` pascal
284	+	TMyComponent = class
285	+	{$DispatchField Msg}
286	+	procedure Dispatch(var aMessage); virtual;
287	+	{$DispatchStrField MsgStr}
288	+	procedure DispatchStr(var aMessage); virtual;
289	+	end;
290	+	TMouseDownMsg = record
291	+	Id: integer; // Id instead of Msg, works in FPC, but not in pas2js
292	+	x,y: integer;
293	+	end;
294	+	TMouseUpMsg = record
295	+	MsgStr: string;
296	+	X,Y: integer;
297	+	end;
298	+	TWinControl = class
299	+	procedure MouseDownMsg(var Msg: TMouseDownMsg); message 3; // warning: Dispatch requires record field Msg
300	+	procedure MouseUpMsg(var Msg: TMouseUpMsg); message 'up'; // ok, record with string field name MsgStr
301	+	end;
302	+	```
303	+
304	+	- added rtti utility functions GetInterfaceProp, SetInterfaceProp, GetMethodProp, SetMethodProp
305	+	- TStream with TBytes
306	+	- TBytesStream
307	+	- convert ord(const) to a const
308	+	- Resource strings:
309	+	- Resource strings can now be written to file. This is controlled by the -Jr option, see the main wiki page for [[pas2js]].
310	+	- TJSFunction(@obj.methodname) is now converted to classtype.methodname
311	+	- Constructors of external classes are now supported in four ways:
312	+	- constructor New is translated to new ExtClass(params). Note the missing JS path.
313	+	- constructor New; external name 'GlobalFunc' is translated to new GlobalFunc(). Note the missing JS path.
314	+	- constructor SomeName; external name '{}' is translated to {} - a basic, empty JS object
315	+	- Otherwise it is translated to new ExtClass.FuncName(params)
316	+	- You can now specify a type for the procedure modifier varargs: *varargs of SomeType***. For example
317	+
318	+	``` pascal
319	+	procedure SumWords(); varargs of Word;
320	+	...
321	+	SumWords(1,2,3); // this works
322	+	SumWords(1,98765); // this gives a range check error
323	+	```
324	+
325	+	- Srcmap for pju files
326	+	- allowing using a unit twice, with different names, e.g. uses ns.unit1, unit1; or uses foo in 'unit1.pas', unit1;
327	+	- option -Sj to allow/disallow typed const to be writable
328	+	- option -im to show available modeswitches
329	+	- option -M\<modeswitch\> to enable or disable a modeswitch, see option -im
330	+	- typecasting unrelated classes now gives only a warning "Class types are not related" instead of an error, Reason: FPC/Delphi compatibility
331	+	- mode ObjFPC now checks procedural types in procedure arguments by signature, reason: FPC compatibility. Note: FPC does that too in \$mode delphi, pas2js only in mode ObjFPC.
332	+	- type helper for bytebool, wordbool, longbool
333	+	- ArrayOfChar:=String and pass string to ArrayOfChar
334	+	- safecall calling convention and rtl catch uncaught [[pas2js exceptions\|exceptions]].
335	+	- [[pas2js AsyncAWait\|Async procedure modifier]] and await functions:
336	+	- function await(AsyncFunctionOfResultT): T; // implicit promise
337	+	- function await(aType; p: TJSPromise): aType; // explicit promise requires the resolved type
338	+	- function await(aType; v: jsvalue): aType; // explicit optional promise requires the resolved type
339	+	- Descending a Pascal class from a JS Function
340	+	- The [[pas2js makestub\|makestub]] utility converts a Pascal import unit for importing Pascal classes to a unit that is compilable by Delphi
341	+	- fcl-json JSON interface from FPC.
342	+	- New units for Javascript libraries:
343	+	- libjitsimeet interface to jitsi video conferencing.
344	+	- libopentok interface to opentok video conferencing.
345	+	- libkurento interface to kurento video conferencing.
346	+	- libfullcalendar(4/5) interface to fullcalendar.io JS library
347	+	- libdatatables interface to datatables.net JS library
348	+	- pushjs interface to browser Push Notifications
349	+	- libbootstrap interface to bootstrap classes.
350	+	- gmaps interface to google maps interface.
351	+	- added separate hints 4501 field "x" not used and 4502 field "x" assigned but never used. Delphi/FPC do not have these hints, as they treat records as one memory block and can't omit fields. pas2js can omit fields.
352	+	- Optimizations:
353	+	- -O2 : Level 2 optimizations (Level 1 + not debugger friendly)
354	+	- -OoShortRefGlobals\[-\]: Insert a JS local var for each module, type and static function. Default enabled in -O2.
355	+
356	+	### 2.0.0 Incompatibilities
357	+
358	+	#### Signature for event handlers TEventListenerEvent and TJSEvent
359	+
360	+	The signature for event handlers has been corrected. The class TEventListenerEvent is now an alias for TJSEvent
361	+
362	+
363	+	That means that the 2 event handler types
364	+
365	+	` TJSEventHandler = reference to function(Event: TEventListenerEvent): boolean;`\
366	+	` TJSRawEventHandler = reference to Procedure(Event: TJSEvent);`
367	+
368	+
369	+	are now equivalent.
370	+
371	+	#### TJSEvent type definition
372	+
373	+	The TJSEvent type definition has been corrected
374	+
375	+
376	+	The currentTarget and Target properties of TJSEvent are now of type TJSEventTarget, as they are in the official specs:
377	+
378	+	` property currentTarget : TJSEventTarget Read FCurrentTarget;`\
379	+	` property target : TJSEventTarget Read FTarget;`
380	+
381	+
382	+	For convenience, a targetElement and CurrentTargetElement property have been added which are of type TJSElement:
383	+
384	+	` property currentTargetElement : TJSElement;`\
385	+	` property targetElement : TJSElement;`
386	+
387	+	#### modeswitch ignoreattributes was removed
388	+
389	+	The workaround {\$modeswitch ignoreattributes} was removed. Attributes are now implemented.

427	+	- New behaviour: search no namespace (i.e. as written in uses section), prepend command line namespaces, prepend default namespace (aka program namespace)
428	+	- For example program that uses "classes" and units classes.pas and system.classes.pas are in unit search path.
429	+	- fixed try exit(value) finally read Result end

614	+
615	+	## Version 1.4.0RC1
616	+
617	+	16th Feb 2019
618	+
619	+	- Highlights:
620	+	- class helpers
621	+	- record helpers
622	+	- type helpers
623	+	- advanced records
624	+	- array of const
625	+	- added locate to JSONdataset, as well as lookup and support for lookup fields.
626	+	- Added Indexes (sorting) to JSONDataset.
627	+
628	+	- Incompatibilities:
629	+	- pas2js now searches units first in the folder of the current module as Delphi does.
630	+	- JSArguments declaration was changed from an array of jsvalue to TJSFunctionArguments.
631	+
632	+	## All changes of version 1.4.0
633	+
634	+	- Pas2js supports class helpers, record helpers and type helpers since 1.3. The extend is only virtual, the helped type is kept untouched.
635	+	- A class helper can "extend" Pascal classes and external JS classes.
636	+	- A record helper can "extend" a record type. In \$mode delphi a record helper can extend other types as well, see type helper
637	+	- A type helper can extend all base types like integer, string, char, boolean, double, currency, and some user types like enumeration, set, range and array types. It cannot extend interfaces or helpers.
638	+	- Type helpers are available by default in \$mode delphi and disabled in \$mode objfpc. You can enable them with {\$modeswitch typehelpers}.
639	+	- By default only one helper is active per type, same as in FPC/Delphi. If there are multiple helpers for the same type, the last helper in scope wins. A class with ancestors can have one active helper per ancestor type, so multiple helpers can be active, same as FPC/Delphi. Using {\$modeswitch multihelpers} you can activate all helpers within scope.
640	+	- Nested helpers (e.g. TDemo.TSub.THelper) are elevated. Visibility is ignored. Same as FPC/Delphi.
641	+	- Helpers cannot be forward defined (e.g. no THelper = helper;).
642	+	- Helpers must not have fields.
643	+	- Class Var, Const, Type
644	+	- Visibility : strict private .. published
645	+	- Function, procedure: In class and record helpers Self is the class/record instance. For other types Self is a reference to the passed value.
646	+	- Class function, class procedure: Helpers for Pascal classes/records can add static and non static class functions. Helpers for external classes and other types can only add static class functions.
647	+	- Constructor. Not for external classes. Works similar to construcors, i.e. THelpedClass.Create creates a new instance, while AnObj.Create calls the constructor function as normal method. Note that Delphi does not allow calling helper construcors as normal method.
648	+	- no destructor
649	+	- Property : getters/setters can refer to members of the helper, its ancestors and the helped class/record.
650	+	- Class property : getter can be static or non static. Delphi/FPC only allows static.
651	+	- Ancestors : Helpers can have an ancestor helper, but they do not have a shared root class, especially not TObject.
652	+	- no virtual, abstract, override. Delphi allows them, but 10.3 crashes when calling.
653	+	- inherited inside a method of a class/record calls helper of ancestor.
654	+	- inherited inside a helper depends on the \$mode:
655	+	- \$mode objfpc : inherited; and inherited Name(args); work the same and searches first in HelperForType, then in ancestor(s).
656	+	- \$mode delphi: inherited; : skip ancestors and HelperForType, searches first in helper(s) of ancestor of HelperForType.
657	+	- \$mode delphi: inherited name(args); : same as \$mode objfpc first searches in HelperForType, then Ancestor(s)
658	+	- In any case if inherited; has no ancestor to call, it is silently ignored, while inherited Name; gives an error.
659	+	- RTTI: typeinfo(somehelper) returns a pointer to TTypeInfoHelper with Kind tkHelper.
660	+	- There are some special cases when using a type helper function/procedure on a value:
661	+	- function result : using a temporary variable
662	+	- const, const argument : When helper function tries to assign a value, pas2js raises a EPropReadOnly exception. FPC/Delphi use a temporary variable allowing the write.
663	+	- property : uses only the getter, ignoring the setter. This breaks OOP, as it allows to change fields without calling the setter. This is FPC/Delphi compatible.
664	+	- with value do ; : uses a temporary variable. Delphi/FPC do not support it.
665	+	- built-in function concat (string1,string2,...)
666	+	- local types (declared inside functions) are now created in the global scope
667	+	- added locate to JSONdataset, as well as lookup and support for lookup fields.
668	+	- Added Indexes (sorting) to JSONDataset.
669	+	- Added unit fpexprpars.pas, an expression parser unit (needed for dataset filtering...)
670	+	- omit unnecessary brackets on associative operations (a\\|\\|b)\\|\\|(c\\|\\|d), (a&&b)&&(c&&d), (a\\|b)\\|c, (a&b)&c, (a^b)^c, (a+b)+c, (a-b)-c, (ab)c
671	+	- *records are now created as Object, instead of JS function***
672	+	- records now have hidden (not enumerable) functions \$new, \$assign, \$clone, \$eq
673	+	- passing records to var argument now passes the record directly instead of creating a temporary setter
674	+	- Assigning a record, e.g. aRecord:=value, now copies the values, while keeping the JS object. This makes pointer of record Delphi/FPC compatible.
675	+	- Advanced records: enabled in \$mode delphi, disabled im \$mode objfpc, enable with {\$modeswitch AdvancedRecords}
676	+	- visibility private, strict private, public, default is public
677	+	- methods, class methods (must be static like in FPC/Delphi), constructors
678	+	- class vars
679	+	- const
680	+	- property, class property, array property, default array property
681	+	- nested types
682	+	- RTTI
683	+	- Records can now have external fields with '\[2\]', '\["a b"\]'
684	+	- In \$mode objfpc forward class-of and pointer declarations can now refer to types even if there are other const/var/resourcestring sections in between. Same a FPC. For example:
685	+
686	+	``` pascal
687	+	type
688	+	TClassOfBird = class of TBird;
689	+	const k = 1;
690	+	type
691	+	TBird = class end;
692	+	```
693	+
694	+	- lo(), hi() in \$mode delphi returning the lo/hi byte, in \$mode objfpc returning the lo/hi byte\\|word\\|longword.
695	+	- char range with non ascii literals: 'Б'..'Я'
696	+	- typecast char to word and other integers
697	+	- added option -Jmabsolute to store absolute filenames in sourcemaps
698	+	- JSArguments declaration was changed from an array of jsvalue to TJSFunctionArguments.
699	+	- fixed expr\[\]\[\] with default properties
700	+	- fixed assigning class vars
701	+	- pas2js now searches units first in the folder of the current module as Delphi does.
702	+	- fixed case-of with non ascii literals
703	+	- implemented ProcVar:=StaticClassMethod
704	+	- implemented ProcVar:=ClassMethod inside static class method
705	+	- class property getter/setter can now be static or non static.
706	+	- array of const:
707	+	- Works the same: vtInteger, vtBoolean, vtPointer, vtObject, vtClass, vtWideChar, vtInterface, vtUnicodeString
708	+	- longword is converted to vtNativeInt instead of mangling to vtInteger
709	+	- vtExtended is double, Delphi/FPC: PExtended
710	+	- vtCurrency is currency, Delphi/FPC: PCurrency
711	+	- Not supported: vtChar, vtString, vtPChar, vtPWideChar, vtAnsiString, vtVariant, vtWideString, vtInt64, vtQWord
712	+	- only in pas2js: vtNativeInt, vtJSValue
713	+	- fixed o.ProcVar() when ProcVar is typeless property
714	+	- fixed const evaluation float - currency
715	+	- fixed reading \#\$00xx as widechar, bug 34923
716	+	- fixed relative paths in srcmap in Windows
717	+	- nicer error message on invalid set element type
718	+
719	+	## Version 1.2.0
720	+
721	+	- 23th Dec 2018
722	+	- SVN release tag is <https://svn.freepascal.org/svn/projects/pas2js/tags/release_1_2_0>

727	+
728	+	## Version 1.2.0RC1
729	+
730	+	- 16th Dec 2018
731	+	- SVN release tag is <https://svn.freepascal.org/svn/projects/pas2js/tags/release_1_2_0RC1>
732	+	- Anonymous Functions:
733	+
734	+	``` pascal
735	+	type
736	+	TRefProc = reference to procedure;
737	+	TProc = procedure;
738	+	procedure DoIt(arg: TRefProc);
739	+	var
740	+	ref: TRefProc;
741	+	proc: TProc;
742	+	begin
743	+	ref:=procedure begin end; // assign to "reference of procedure" type
744	+	ref:=procedure // note the omitted semicolon
745	+	var i: integer; // var, types, const, local procedures
746	+	begin
747	+	end;
748	+	DoIt(procedure begin end); // pass as argument
749	+	refproc:=procedure assembler asm // embed JavaScript
750	+	console.log("foo");
751	+	end;
752	+	// Note that typecasting to non "reference to" does not make a difference
753	+	// because in JS all functions are closures:
754	+	proc:=TProc(procedure begin end);
755	+	end;
756	+	```
757	+
758	+	- added variable <i>rtl.version</i>, which corresponds to the compiler version Major10000+Minor100+Release
759	+	- added option -JoCheckVersion:
760	+	- -JoCheckVersion- : do not add rtl version check, default.
761	+	- -JoCheckVersion=main : insert rtl.checkVersion() into main.
762	+	- -JoCheckVersion=system : insert rtl.checkVersion() into system unit.
763	+	- -JoCheckVersion=unit : insert rtl.checkVersion() into every unit.
764	+	- moved classtopas function to a class2pas unit, improved the interface so it uses a stringlist. Adapted the demo.
765	+	- Fix System.Int() so it also works on IE (where Math.trunc is missing).
766	+	- allow typecasting string(apointer) and pointer(astring)
767	+	- asm-block now skips Pascal comments //... and Pascal string literals with single quotes. It no longer stops at end in such comments and string literals.
768	+	- Fix FormatFloat() rounding logic (actually FloatToDecimal)
769	+	- Fix stringofchar for count\<=0
770	+	- Fix quotestring and add quotedstr
771	+	- implemented special includes like {\$i %date%}:
772	+	- %date%: current date as string literal, '\[yyyy/mm/dd\]'
773	+	- %time%: current time as string literal, 'hh:mm:ss' Note that the inclusion of %date% and %time% will not cause the compiler to recompile the unit every time it is used: the date and time will be the date and time when the unit was last compiled.
774	+	- %line%: current source line number as string literal, e.g. '123'
775	+	- %linenum%: current source line number as integer, e.g. 123
776	+	- %currentroutine%: name of current routine as string literal
777	+	- %pas2jstarget%, %pas2jstargetos%, %fpctarget%, %fpctargetos%: target os as string literal, e.g. 'Browser'
778	+	- %pas2jstargetcpu%, %fpctargetcpu%: target cpu as string literal, e.g. 'ECMAScript5'
779	+	- %pas2jsversion%, %fpcversion%: compiler version as string literal, e.g. '1.0.2'
780	+	- If param is none of the above it will use the environment variable. Keep in mind that depending on the platform the name may be case sensitive. If there is no such variable an empty string is inserted.
781	+	- implemented pred(char), succ(char)
782	+	- allow typecasting TypedPointer(UntypedPointer)
783	+	- allow assign UntypedPointer:=TypedPointer
784	+	- skip double quotes in asm-blocks, e.g. s = "end"+"'";
785	+	- added {\$modeswitch OmitRTTI}: treat class section 'published' as 'public' and typeinfo() does not work on symbols declared with this switch. This allows to easily disable generating RTTI and allows the optimizer to omit unused published properties.
786	+	- added option -Jpcmd\<command\>: Run postprocessor. For each generated js execute command passing the js as stdin and read the new js from stdout. This option can be added multiple times to call several postprocessors in succession. Quote the \<command\> to add options for the postprocessor. For an example see [[pas2js minifier\|minifier]].
787	+	- Added built-in procedure Debugger;, which is converted to the JavaScript statement <i>debugger;</i>. If a debugger is running it will break on this line just like a break point.
788	+	- Changed operator precedence level of is to same as and, or, xor. Same as fpc/delphi.
789	+	- fixed assert to raise on false, bug 34643
790	+	- built-in procedure val(const string; out enum; out int)
791	+	- added option -JoRTL-\<x\>=\<y\> to change the name of a autogenerated identifier. See the list of available identifiers with -iJ.
792	+

824	+
825	+	`function GetItems(const i: integer): byte;`\
826	+	`property Items[i: integer]: byte read GetItems;`
827	+
828	+	- fixed high(intvar)
829	+	- fixed WPO when using record constants
830	+	- fixed include(FuncResultSet,enum)

840	+	- fixed selecting procedure overload, preferring lossy int over int to float
841	+	- fixed calling Free inside method
842	+	- fixed System.Int() so it also works on IE (where Math.trunc is missing).
843	+	- fixed FormatFloat() rounding logic (actually FloatToDecimal)
844	+	- fixed stringofchar for count\<=0
845	+	- fixed quotestring and add quotedstr

857	+	- fixed generating srcmap for precompiled javascript
858	+
859	+	## Version 1.0.0
860	+
861	+	- 9 Aug 2018
862	+	- SVN release tag is <https://svn.freepascal.org/svn/projects/pas2js/tags/release_1_0_0>
863	+	- SVN fixes branch is <https://svn.freepascal.org/svn/projects/pas2js/branches/fixes_1_0>
864	+	- fixed override method of class interface
865	+	- fixed crash on checking body element of empty proc
866	+	- use default source filename in pcu/pju files
867	+
868	+	## Version 1.0.0rc1
869	+
870	+	- 24 Jul 2018
871	+	- fixed TObject.Create()
872	+	- -vd shows stacktraces

882	+	- fixed aIntSet:=\[0\]
883	+	- fixed crash on List.Items.Dummy
884	+	- fixed some mem leaks
885	+	- fixed -MDelphi + \$mode objfpc + overloads withouts overload keyword
886	+	- TGUIDString is now type string
887	+	- RTL: added websockets
888	+
889	+	## Version 0.9.30
890	+
891	+	- 4 Jul 2018
892	+	- fixed calling COM interface _Release function for expressions.
893	+	- fixed catching exception in pju variant of pas2js
894	+	- 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.
895	+	- fixed property RTTI for alias type in other unit
896	+	- fixed default value of integer variables, using 0 even if it is outside range. Reason: Delphi/FPC compatibility.
897	+
898	+	## Version 0.9.29
899	+
900	+	- 29 Jun 2018
901	+	- fixed pcu reading alias type
902	+	- fixed analyzer: element needing typeinfo marks indirect elements as used normally

904	+	- \$warn BOUNDS_ERROR off: disable range check warnings at compile time
905	+	- \$warn MESSAGE_DIRECTIVE off: disable \$message notes
906	+
907	+	## Version 0.9.28
908	+
909	+	- 27 Jun 2018
910	+	- fixed static array of char = stringlit+stringlit
911	+	- fixed libpas2js disk full error
912	+	- \$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.
913	+	- CONSTRUCTING_ABSTRACT: Constructing an instance of a class with abstract methods.
914	+	- IMPLICIT_VARIANTS: Implicit use of the variants unit.
915	+	- NO_RETVAL: Function result is not set
916	+	- SYMBOL_DEPRECATED: Deprecated symbol
917	+	- SYMBOL_EXPERIMENTAL: Experimental symbol
918	+	- SYMBOL_LIBRARY
919	+	- SYMBOL_PLATFORM: Platform-dependent symbol

926	+	- mode delphi: fixed passing static array to open array
927	+	- allow assigning aTypeInfo:=pointer, needed by units with and without using unit typinfo
928	+
929	+	## Version 0.9.26
930	+
931	+	- 25 Jun 2018
932	+	- typecast function address to JS function, e.g. TJSFunction(@IntToStr)
933	+	- typecast function reference to JS function, e.g. TJSFunction(OnClick)
934	+	- 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.
935	+	- 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.
936	+	- 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.
937	+	- Assignation using constant array. For instance Arr:=\[1,2,3\], where Arr is a dynamic array.
938	+	- + operator for arrays: This concatenation operator is available using the new modeswitch arrayoperators, which is enabled by default in mode delphi.
939	+	- unit webgl updated
940	+	- unit webaudio added
941	+	- unit webbluetooth added

948	+	- 5024 for others
949	+
950	+	## Version 0.9.25
951	+
952	+	- 7 Jun 2018
953	+	- TComponent now supports IInterface
954	+	- -o is now always relative to working directory, even if -FU or -FE is given. Reason: FPC compatibility
955	+	- fixed typeinfo(typeintegerrange)
956	+	- fixed using interface ancestor methods
957	+	- fixed 'make' building with fpc 3.0.4
958	+
959	+	## Version 0.9.24
960	+
961	+	- 2 Jun 2018
962	+	- fixed precompiled js formatting to same options as compiled js
963	+	- fixed unit analyzer private method used by protected property
964	+	- fixed class-of RTTI
965	+	- fixed precompiled resolve pending scopes before pending units
966	+
967	+	## Version 0.9.23
968	+
969	+	- 28 May 2018
970	+	- added webgl demos from Ryan Joseph
971	+	- for value in jsarray do - where jsarray is any external class with a matching length and default property. This enumerates similar to other arrays the values, not the index.
972	+	- allow typecast array to TJSObject
973	+	- allow typecast TJSObject to array
974	+	- Unicode character constants outside of BMP, e.g. \#\$10437
975	+	- allow {\$H+}, error on {\$H-}
976	+	- added intrinsic procedure WriteStr(out s: string; params...), which works similar to str(param,s), except it can take any amount of parameters, which are concatenated.
977	+	- added option -Sm to enable macro replacements
978	+
979	+	## Version 0.9.22
980	+
981	+	- 17 May 2018

983	+
984	+	## Version 0.9.21
985	+
986	+	- 16 May 2018
987	+	- added option -FE: set the main output path, used for the main .js file, if there is no -o option or the -o option has no folder.
988	+	- fixed WPO typeinfo of inherited property
989	+	- for easier FPC integration the following message IDs were changed:
990	+	- nVirtualMethodXHasLowerVisibility = 3250; // was 3050
991	+	- nConstructingClassXWithAbstractMethodY = 4046; // was 3080
992	+	- nNoMatchingImplForIntfMethodXFound = 5042; // was 3088
993	+	- nSymbolXIsDeprecated = 5043; // was 3062

996	+	- nSymbolXIsNotPortable = 5076; // was 3058
997	+	- nSymbolXIsNotImplemented = 5078; // was 3060
998	+	- nSymbolXIsExperimental = 5079; // was 3059
999	+

1001	+
1002	+	- 11 May 2018
1003	+	- fixed passing typecasted alias type to var parameter
1004	+	- forbid typecast rectordtype to other recordtype
1005	+	- remove leading zeroes in number literals
1006	+	- added namespace option -FN\<x\>, marked -NS as obsolete. Reason: fpc compatibility.
1007	+	- added option -vz : write messages to stderr, -o. still uses stdout.
1008	+	- added option -ic : Write list of supported JS processors usable by -P\<x\>
1009	+	- added option -io : Write list of supported optimizations usable by -Oo\<x\>
1010	+	- added option -it : Write list of supported targets usable by -T\<x\>
1011	+	- added option -SIcom, -SIcorba interface style
1012	+	- added option -vv : Write pas2jsdebug.log with lots of debugging info
1013	+	- fixed option -va including option -vt
1014	+	- fixed combination of -Jc -o.

1018	+
1019	+	## Version 0.9.19
1020	+
1021	+	- 2 May 2018
1022	+	- type alias type, e.g. type TCaption = type string;
1023	+	- record const, e.g. const p: TPoint = (x:1; y:2);
1024	+	- {\$WriteableConst on\\|off}: treat typed constants as readonly, e.g. const i:byte=3;... i:=4; creates a compile time error.
1025	+	- forbid assignment of for-loop variable
1026	+	- nested classes
1027	+	- property specifier nodefault
1028	+	- default(type) returning the initial value of the type, e.g. default(recordtype).
1029	+	- external typed const: e.g. const NaN: Double; external name 'NaN';
1030	+	- case string of support for ranges
1031	+	- fixed typecast shortint(integer)
1032	+
1033	+	## Version 0.9.18
1034	+

1041	+	- Fix recno calculation for TJSONDataset
1042	+	- Fix initializing next buffers in TDataset.
1043	+	- Implemented Currency as double, values are multiplied by 10000 and truncated, so a 2.7 is stored as 27000.
1044	+	- Implemented pointer of record. It's simply a reference.
1045	+	- p:=@r translates to p=r
1046	+	- p^.x becomes p.x
1047	+	- intrinsics new(PointerOfRecord), dispose(PointerOfRecord). dispose(p) sets p to null if possible.
1048	+	- enumerator for jsvalue: e.g. var v: jsvalue; key: string; for key in jsvalue do** translates to for (key in jsvalue){}
1049	+	- enumerator for external class: e.g. var o: TJSObject; key: string; for key in o do translates to for (key in o){}
1050	+	- range checking \$R+
1051	+	- compile time: warnings become errors
1052	+	- run time: int:=, int+=, enum:=, enum+=, intrange:=, intrange+=, enumrange:=, enumrange+=, char:=, charrange:=
1053	+	- run time: parameters: int, enum, intrange, enumrange, char, charrange
1054	+	- run time: array\[index\], string\[index\]
1055	+	- type cast integer to integer, e.g. byte(aLongInt)
1056	+	- with range checking enabled: error if outside range
1057	+	- without range checking: emulates the FPC/Delphi behaviour: e.g. byte(value) translates to value & 0xff, shortint(value) translates to value & 0xff \<\<24 \>\>24.
1058	+	- case-of statement: error on duplicate values
1059	+	- fixed error on int:=double
1060	+
1061	+	## Version 0.9.16
1062	+
1063	+	- 21 Apr 2018
1064	+	- mode delphi: allow "ObjVar is IntfType" and "ObjVar as IntfType" with unrelated types.
1065	+	- TVirtualInterface - create an implementation at runtime. rtl unit rtti.pas
1066	+	- typecast a class type to JS Object, e.g. TJSObject(TObject)
1067	+	- typecast an interface type to JS Object, e.g. TJSObject(IUnknown)
1068	+	- typecast a record type to JS Object, e.g. TJSObject(TPoint)
1069	+	- <i>not jsvalue</i> is converted to <i>!jsvalue</i>

1072	+	- TGUID record
1073	+	- GuidVar:='{guid}', StringVar:=GuidVar, GuidVar:=IntfTypeOrVar, GuidVar=IntfTypeOrVar, GuidVar=string
1074	+	- pass IntfTypeOrVar to GuidVar parameter
1075	+	- added new type TGuidString to system unit
1076	+	- GuidString:=IntfTypeOrVar, GuidString=IntfTypeOrVar
1077	+	- pass IntfTypeOrVar to GuidString parameter
1078	+	- added option -JoUseStrict, to enable or disable adding "use strict"
1079	+
1080	+	## Version 0.9.15
1081	+
1082	+	- 8 Apr 2018
1083	+	- fixed crash when ancestor implements more interfaces than current class.
1084	+
1085	+	## Version 0.9.14
1086	+
1087	+	- 8 Apr 2018
1088	+	- fixed duplicates in rtl/strutils.pas
1089	+	- fixed reference counts on reading element lists
1090	+	- implemented using function result variable in for-loop. e.g. <i>for Result:=...</i>, <i>for Result in ...</i>
1091	+	- fixed <i>for string in arrayofstring do</i>
1092	+	- fixed \$scopedenums with anonymous enumtype. e.g. <i>type TSet = set of (A,B);</i>
1093	+	- implemented class interfaces:
1094	+	- methods, properties, default property
1095	+	- {\$interfaces com\\|corba\\|default}
1096	+	- 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
1097	+	- CORBA: lightweight, no automatic reference counting, no default ancestor, fast support checks.
1098	+	- inheriting
1099	+	- GUIDs are simple string literals, TGUID = string.
1100	+	- An interface without a GUID gets one autogenerated from its name and method names.
1101	+	- a class implementing an interface must not be external
1102	+	- 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.
1103	+	- method resolution, <i>procedure IUnknown._AddRef = IncRef;</i>
1104	+	- delegation: <i>property Name: interface\\|class read Field\\|Getter implements AnInterface;</i>
1105	+	- is-operator:
1106	+	- IntfVar is IntfType - types must be releated
1107	+	- IntfVar is ClassType - types can be unrelated, class must not be external
1108	+	- ObjVar is IntfType - can be unrelated
1109	+	- as-operator
1110	+	- IntfVar as IntfType - types must be releated
1111	+	- IntfVar as ClassType - types can be unrelated, nil returns nil, invalid raises EInvalidCast
1112	+	- ObjVar as IntfType - mode delphi: types must be related, objfpc: can be unrelated, nil if not found, COM: uses _AddRef
1113	+	- typecast:
1114	+	- IntfType(IntfVar) - must be related
1115	+	- ClassType(IntfVar) - can be unrelated, nil if invalid
1116	+	- IntfType(ObjVar) - mode delphi: must be related, objfpc: can be unrelated, nil if not found, COM: if ObjVar has delegate uses _AddRef
1117	+	- TJSObject(intfvar)
1118	+	- Assign operator:
1119	+	- IntfVar:=nil
1120	+	- IntfVar:=IntfVar2 - IntfVar2 must be same type or a descendant
1121	+	- IntfVar:=ObjVar - nil if unsupported
1122	+	- jsvalue:=IntfVar
1123	+	- Assigned(IntfVar)
1124	+	- RTTI
1125	+	- \$modeswitch ignoreinterfaces was removed
1126	+	- Not supported: array of interface, interface as record member

1141	+
1142	+	- 16 Mar 2018
1143	+	- fixed loading files encoded in non UTF-8, e.g. UTF-8 with BOM. This was a regression.
1144	+

1146	+
1147	+	- 13 Mar 2018
1148	+	- fixed renaming overloads of unit interface at end of interface, not at end of module. Needed for unit cycles.

1169	+	- static arrays are now cloned on assignment or when passed as argument to a function (no const, var, out)
1170	+	- Fixed array\[enum..enum\] of
1171	+	- pas2jslib: fixed checks of directoryexists to use cache
1172	+	- uses with <i>in</i>-filename: In <i>\$mode delphi</i> the in-filenames are only allowed in the program and the unitname must fit the filename, e.g. <i>uses unit1 in 'sub/Unit1.pas'</i>. In <i>\$mode objfpc</i> units can use in-filenames too and alias are allowed, e.g. <i>uses foo in 'bar.pas'</i>.
1173	+

1389	+
1390	+	- 14 Sep 2017
1391	+	- Static array const are now implemented. For example:
1392	+	- array\['a'..'d'\] of integer = (1,2,3,4);
1393	+	- array\[1..3\] of char = 'pas';
1394	+
1395	+	## Version 0.8.19
1396	+
1397	+	- 12 Sep 2017
1398	+	- several bug fixes

1405	+	- array\[char\] of boolean // Note that char is widechar!
1406	+	- low(), high()
1407	+
1408	+	## Version 0.8.18
1409	+
1410	+	- 6 Sep 2017
1411	+	- Anonymous arrays in record members are now supported:
1412	+
1413	+	``` pascal
1414	+	TFloatRec = Record

1417	+	End;
1418	+	```
1419	+
1420	+	## Version 0.8.17

1424	+	- fixed proc type of procedure in Delphi mode
1425	+	- implemented @@ operator for proc types in Delphi mode.
1426	+	- compile time evaluation, range and overflow checking for boolean, base integer types, enums, sets, custom integer ranges, char, widechar, string, single and double.
1427	+
1428	+	## Version 0.8.16
1429	+
1430	+	- 28 Jul 2017
1431	+	- bugfix release.
1432	+
1433	+	## Version 0.8.15
1434	+
1435	+	- 8 Jul 2017
1436	+	- compiler can now generate source maps when passing option -Jm
1437	+
1438	+	## Version 0.8.14
1439	+
1440	+	- 17 May 2017
1441	+	- now supports TObject.Free.
1442	+
1443	+	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.
1444	+
1445	+	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.
1446	+
1447	+	## Version 0.8.13
1448	+
1449	+	- 11 May 2017

1453	+	- \$Error
1454	+	- \$Warning,
1455	+	- \$Note
1456	+	- \$Hint
1457	+	- And in the config files it supports \#IF, \#IFDEF, \#IFNDEF, \#ELSEIF, \#ELSE, \#ENDIF.
1458	+
1459	+	## Version 0.8.12
1460	+
1461	+	- 5 May 2017
1462	+	- dotted unit names and namespaces.
1463	+
1464	+	## Version 0.8.11
1465	+
1466	+	- 23 Apr 2017
1467	+	- dynamic arrays can now be initialized with a constant. Same syntax as static arrays: const a: array of string = ('one', 'two');
1468	+	- Classes can now be declared in the unit implementation.
1469	+	- Unit nodejs now has a console class TNJSConsole.
1470	+	- I added the fpcunit package. Successful tests already work. A fail is not yet caught.
1471	+
1472	+	## Version 0.8.10
1473	+
1474	+	- 22 Apr 2017
1475	+	- you can now use "if aJSValue then", which works just like the JS "if(v)".
1476	+	- added ParamCount, ParamStr, GetEnvironment* functions. The default is not doing much.
1477	+	- new package fcl_base_pas2js, containing custapp and nodejsapp: - TCustomApplication is the known class from the FCL, but with abstract methods.
1478	+	- TNodeJSApplication is a TCustomApplication using nodejs to read command line params and environment variables.
1479	+
1480	+	## Version 0.8.9
1481	+
1482	+	- 21 Apr 2017
1483	+	- The compiler now has the types 53bit NativeInt and 52bit NativeUInt. Keep in mind that there is still no range checking.
1484	+
1485	+	Current aliases:
1486	+
1487	+	JSInteger = NativeInt;
1488	+
1489	+	Integer = LongInt;
1490	+	Cardinal = LongWord;
1491	+	SizeInt = NativeInt;
1492	+	SizeUInt = NativeUInt;
1493	+	PtrInt = NativeInt;
1494	+	PtrUInt = NativeUInt;
1495	+	ValSInt = NativeInt;
1496	+	ValUInt = NativeUInt;
1497	+	ValReal = Double;
1498	+	Real = Double;
1499	+	Extended = Double;
1500	+
1501	+	Int64 = NativeInt unimplemented;
1502	+	QWord = NativeUInt unimplemented;
1503	+	Single = Double unimplemented;
1504	+	Comp = Int64 unimplemented;
1505	+
1506	+	UnicodeString = String;
1507	+	WideString = String;
1508	+	WideChar = char;
1509	+
1510	+	## Version 0.8.8
1511	+
1512	+	- 20 Apr 2017
1513	+	- bugfix release.
1514	+
1515	+	## Version 0.8.7
1516	+
1517	+	- 18 Apr 2017
1518	+	- \$mod: the current module
1519	+	- Self: in a method with nested functions this holds the class or class instance.
1520	+	- 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.
1521	+	- cardinal is no longer a base type, but longword is. Same as FPC.
1522	+
1523	+	## Version 0.8.6
1524	+
1525	+	- 17 Apr 2017
1526	+	- bugfix release.
