How I use DWS with Free Pascal?

[GoogleCodeExporter]

Hello,

What the steps to use DWScript with Free Pascal/Lazarus? I searched a LPK 
(Lazarus package) to install DWS in Lazarus, but seems that it does not exists.

Thank you!

So, I'm planning to use a pascal scripter in a new ideia that will be 
implemented in Brook framework 
(https://github.com/silvioprog/brookframework/issues/51).

If DWS run fine in Free Pascal, I'll create a broker for DWS too. (y)

You can try CodeTyphon LPK files
C:\codetyphon\lazarus\components\pl_DWScript
and samples
C:\codetyphon\CodeOcean\DWScript
Erick can check and integrate this files in Source.

Hm... So, where do I download the pl_DWSScrip package?

Is there a repository where the lpk can be found? (without installing 
CodeTyphon)

As for using DWS in FreePascal, you can just add the units to your uses and 
create the components directly, DWS isn't very "visual" anyway, so there isn't 
much added benefits to having the components in a module or form at design-time.

I'll admit to never having used LPK files, or gone through the trouble of 
setting up an environment to rebuild the Lazarus IDE, I usually just get a 
pre-compiled one from the snapshots.

Thenk you friend,

I'll test DWS in Linux too. If it works fine in Linux Mint 64, I can create a 
LPK file and send a patch.

I saw a DWS copy on Github too:

Silvio https://github.com/alexvins/dwscript is 2 years old source
Try this
1. Dowload CodeTyphon and extract
2. Extract C:\CodeTyphonIns\installbin\allzips\src\typhon_src.7z
C:\CodeTyphonIns\installbin\allzips\src\typhon_src.7z\typhon\components\pl_DWScr
ipt\
This is DWScript source for installation (FPC 2.7.1).
3. Extract Samples 
C:\Install\Lazarus\CodeTyphonIns\installbin\allzips\src\CodeOcean.7z\CodeOcean\D
WScript\samples\

Test your installation

4. Try to merge trunk version of DWScript (DWS is updated every day and maybe 
some fpc compatibility is lost.

Have fun!

You'll need latest FPC (2.7 branch), the code requires generics and Unicode.
The alexvins repo was an attempt at supporting 2.6, but there were too many 
missing tidbits in FPC.

There are still holes in the FPC 2.7 RTL for Unicode, so some string functions 
may fail or return incorrect results, and overall performance will be lower 
than in Delphi (which benefits from asm in key places).

[GoogleCodeExporter]

Committed a bunch FPC compatibility fixes.

One major remaining issue is the lack of a UnicodeString-based TStrings in FPC, 
along with a few other FPC RTL core features that don't have UnicodeString 
variants, this causes the bulk of the warnings I'm seeing here.

I think that you need to add the directive in all units, e.g.:

Free Pascal mode:

{$IFDEF FPC}
  {$mode objfpc}{$H+}
{$ENDIF}

or in Delphi mode:

{$IFDEF FPC}
  {$mode delphi}
{$ENDIF}

Ah, you already have it. So:

unit dwsDataContext;

{$I dws.inc}

...

unit dwsJSON;

{$I dws.inc}

...

unit dwsCompilerUtils;

{$I dws.inc}

Posted some fixes for FPC compilation, though at the moment the FPC 2.7.1 
compiler support for generics is broken (I'm getting an internal error: 
Undefined symbol: VMT_$DWSUTILS_$$_$GENDEF315 in the latest nightlies)

Most of the other issues remaining are Unicode/Ansi implicit conversion, which 
boil down to missing UnicodeString overloads in the FPC RTL, and the FPC RTL 
TStrings still being Ansi-based rather than Unicode.

Friends, unfortunately I couldn't compile it. :/

Is there prediction when the DWS will be compatible with Free Pascal?

Original comment by silvioprog on 11 Sep 2013 at 6:02

[GoogleCodeExporter]

It's mostly in the hands of FPC compiler guys (for the $GENDEF error in recent 
2.7 branch) and the FPC/Lazarus guys (for UnicodeString support in the RTL)... 

Though there hasn't been much progress on the Unicode front lately AFAICT, and 
the subject still seems to be taboo in the FPC mailing lists. The {$MODESWITCH 
UNICODESTRINGS} hack only affects local units, the RTL files are unaffected, so 
is is no alterantive to having the RTL by UnicodeString compatible.

If you want to help with that, I suppose the best option would be to work on an 
Unicode-capable RTL for FPC (from the basics like IntToStr or Pos up to classes 
like TStrings). Some might be tougher nuts to crack (like TClass.ClassName or 
the RTTI)

Hm... at the moment I'm out of time to study the code, understand it and solve 
this problem, so I'll wait for something new.

Anyway, thank you very much friend! (y)

@Zotov How did you get around the Unicode issues in FPC? Do the unit tests pass?

I downloaded your fork and tried to compile the demo uploaded in this issue, 
but the error continues. ;(

Please, can you show a small sample working?

Thank you!

first of all try build Lazarus\dwsLibRuntime.lpk
if you have no errors 
try
Test\LanguageTests.lpr

if you have errors tell me fpc an lazarus version
I use 
Free Pascal Compiler version 2.6.2
Lazarus 1.0.12

And your OS/Platform
I check on Win32/64 and Linux x64

Now the error is:

"The program can not start because it is missing BeaEngine32.DLL on your 
computer. Try to reinstall it to resolve this issue."

My environment:

Lazarus 1.0.14 r43446 FPC 2.6.2 i386-win32-win32/win64.

It's in Tools\BeaEngine, and used only as part of the JIT compiler unit tests.

Your test execution timings are way too fast, I suspect it didn't actually run 
the tests (or couldn't find the tests files)

to fix TdwsJSONTests.ParseJSON error you need test data 
copy /Test/Data/ to path with executable file

Windows i test on same version, but have no errors with Float
(Win64 native, Win32 WINE) 
can you help me to reproduce it?
i think problem in floating point accuracy
you can debug it in function 
TRelNotEqualFloatExpr.EvalAsBoolean
from unit dwsRelExprs

run only one test, what fails

Friend, sorry for my long delay. I'll debug this function tomorrow in my laptop 
and post the result here ...
