DWScript is an object-oriented scripting engine for Delphi based on the Delphi language, with extensions borrowed from other Pascal languages (FreePascal, Prism, etc.). It introduces a few Pascal language extensions of its own as well.

Goals of the project go beyond web usages, and cover general purpose scripting.

To get started see FirstSteps or [Language], for news see the posts tagged "DWS" at DelphiTools.info. You can also have a look at the [FAQ]. If you have other questions related to DWScript programming, usage or integration, StackOverflow is a good place to ask them. For bugs, use the Issues tracker.

This project is currently maintained by Eric Grange (http://delphitools.info), and sponsored by Creative IT, it is based on original DWS2 by Matthias Ackermann (http://sourceforge.net/projects/dws/) initiated way back in the last century.

DWScript lead platform is currently Delphi 10.3, compatibility with older Delphi version is not officially maintained, it may work, or it may not.

Which repo to use? (BitBucket/GitHub)

Doesn't seem obvious - what's the purpose of two different repos?

The GitHub version seems to have more package files, and extra files for Delphinus but source code differs from Eric's BitBucket repo.

Suggest updating the main readme

Delphinus.Install.json is no valid json

there is at least one wrong comma at the end of the json file. Loading fails on Delphi XE :(
http://jsonlint.com/ reports that it's invalid, too

10.2 for Linux

When to update the 10.2 for Linux version?

Assign anonymous record to variant

Hello,
Why are "Anonymous record" not compatible with "Variant"? I tried to use CodeGen from dws program bellow:

program Test;

type TFunc = function(y: integer): integer;

procedure DoSomething(func: TFunc);
begin
end;

begin
 var t, y: variant;
 t := record
   name = 8;
   height = 10;
   size: record
     name = 'tool';
   end;
 end;
 
 DoSomething(lambda(y) => y+1);
 
 y.name := 7;
 
 t := y;
 
end.

The output is: there are former version of DWS that allow it.
