Pascal Script


PASCAL SCRIPT FOR DELPHI



Pascal Script is a free scripting engine that allows you to use most of the
Object Pascal language within your Delphi or Free Pascal projects at runtime.
Written completely in Delphi, it is composed of a set of units that can be
compiled into your executable, eliminating the need to distribute any external
files. Pascal Script started out as a need for a good working script, when there
were none available at the time.




WHY USE A SCRIPTING ENGINE?

A scripting engine allows an end user to customize an application to his or
her needs without having to recompile it. In addition, you can update your
applications by just sending a new script file that could even be compiled to
byte code, which cannot easily be transformed back to source code.



Pascal Script includes the following features:

 * Variables, Constants
 * Standard language constructs:
   * Begin/End
   * If/Then/Else
   * For/To/Downto/Do
   * Case x Of
   * Repeat/Until
   * While
   * Uses
   * Exit
   * Continue
   * Break
 * Functions inside the script
 * Calling any external DLL function (no special function headers required)
 * Calling registered external methods
 * All common types like Byte, Shortint, Char, Word, SmallInt, Cardinal,
   Longint, Integer, String, Real, Double, Single, Extended, Boolean, Array,
   Record, Enumerations, Variants
 * Allows the importing and use of classes, with events, properties, methods and
   constructors
 * Allows the importing and use of interfaces and their members
 * Allows IDispatch dynamic method invocation through Variant
 * Assignment of script functions to Delphi events
 * Uses byte code as an intermediate format and allows the storing and reloading
   of compiled scripts
 * Easy to use component version
 * Support for include files
 * Support for compiler defines
 * Capability to call RemObjects SDK Services from within scripts
 * Includes a tool to create headers for importing classes and interfaces


HISTORY



Pascal Script started out in 2001 with CajScript 1.0, which was soon superseded
by CajScript 2.0 (later called Innerfuse Pascal Script 2.0). Version 2.0
interpreted scripts while it ran them, which had the disadvantage that every
piece of code had to be reparsed every time the script engine went over it. With
Pascal Script 3.0, this was changed to a new model, where the compiler and
runtime were completely separated from each other and used a custom byte code
format to represent the compiled script. This compiled script only contained the
bare minimum that was required to execute the code. Later, when Carlo Kok joined
RemObjects, it was renamed RemObjects Pascal Script and is now being maintained
by RemObjects Software.

One prominent use of Pascal Script is the Open Source InnoSetup project.
InnoSetup is a widely used setup engine that uses Pascal Script as scripting
engine to provide advanced scripting abilities during installation and
uninstallation. Using Pascal Script, users can customize almost all parts of the
setup, add new wizard pages, call into dlls to add advanced features and provide
custom behavior and install conditions.

Pascal Script is also leveraged extensively by our own Data Abstract for Delphi
to provide business rules scripting.
