Description
DWS is an OpenSource project. Our goal is to create a multi-purpose scripting language for use in Borland Delphi projects. DWS is distributed under Mozilla Public License 1.1

Programming Language
The programming language supported by DWS is a subset of Delphi pascal. DWSII supports all important features of an object orientated programming language.

Connection to Delphi
DWS is an invisible Delphi component. To execute a script you just have to call the component's compile method. Compile returns a TProgram object that executes your script.

To call a native-Delphi function from within a DWS script, you have to declare a DWS-wrapper-function using the Tdws2Unit component. As soon as this function is called, it's "OnEval" event is fired. The event handler now executes every Delphi code you wrote...

Technical Details
DWS uses a recursive parser to transform a script program into a data structure called "Abstract Syntax Tree" (AST). During the execution the compiled AST is beeing evaluated. Information about the variables, data types and classes used in the script program is maintained in a separate symbol table.

DWS is a typed language. This means that you have to declare a variable before you can use it. Therefore the compiler is able to find type mismatches at compile time.
