Writing Plugins#

+

Simba scripts can be extended with plugins. +Plugins are libraries (dll/so/dylib) which can be written in virtually every low-level language.

+
+

Note

+

The cdecl calling convention is used for 32bit, otherwise the default systems calling convention is used.

+
+
+
+

Importing functions#

+

To import functions the following methods must be exported to provide information to Simba.

+
function GetFunctionInfo(Index: Integer; var Address: Pointer; var Header: PChar): Integer; cdecl;
+function GetFunctionCount: Integer; cdecl;
+
+
+
+

Note

+
+
Appending native; to the header cause parameters and result passed in the lape wrapper format.
+
This is the preferred way, otherwise libffi is used.
+
+

The Lape wrapper format is:

+
procedure(const Params: PParamArray; const Result: Pointer);
+
+
+
+
+
+
+

Importing types#

+

To import types the following methods must be exported to provide information to Simba.

+
function GetTypeInfo(Index: Integer; var Name: PChar; var Str: PChar): Integer; cdecl;
+function GetTypeCount: Integer; cdecl;
+
+
+
+

Note

+

These methods are imported before GetFunctionInfo & GetFunctionCount so these types will be available when adding functions.

+
+
+
+
+

Importing code#

+

Code can be imported in the script with the following methods exported.

+
procedure GetCode(var Code: PChar); cdecl;
+function GetCodeLength: Integer; cdecl;
+
+
+
+
+
+

RegisterSimbaPlugin#

+

A plugin can export RegisterSimbaPlugin which provides access to various Simba’s infomation & methods.

+
procedure RegisterSimbaPlugin(Infomation: PSimbaInfomation; Methods: PSimbaMethods); cdecl;
+
+
+

These pointers are provided to these structures:

+
TSimbaInfomation = packed record
+  SimbaVersion: Integer;
+  SimbaMajor: Integer;
+
+  FileName: PChar;
+
+  Compiler: Pointer;
+end;
+
+TSimbaMethods = packed record
+  RunOnMainThread: procedure(Method: TMainThreadMethod; Data: Pointer = nil); cdecl;
+
+  GetMem: function(Size: NativeUInt): Pointer; cdecl;
+  FreeMem: function(P: Pointer): NativeUInt; cdecl;
+  AllocMem: function(Size: NativeUInt): Pointer; cdecl;
+  ReAllocMem: function(var P: Pointer; Size: NativeUInt): Pointer; cdecl;
+  MemSize: function(P: Pointer): NativeUInt; cdecl;
+
+  RaiseException: procedure(Message: PChar); cdecl;
+
+  GetTypeInfo: function(Compiler: Pointer; Typ: PChar): Pointer; cdecl;
+  GetTypeInfoSize: function(TypeInfo: Pointer): NativeInt; cdecl;
+  GetTypeInfoFieldOffset: function(TypeInfo: Pointer; FieldName: PChar): NativeInt; cdecl;
+
+  AllocateArray: function(TypeInfo: Pointer; Len: NativeInt): Pointer; cdecl;
+  AllocateString: function(Data: PChar): Pointer; cdecl;
+  AllocateUnicodeString: function(Data: PUnicodeChar): Pointer; cdecl;
+  AllocateIntegerArray: function(Len: NativeInt): Pointer; cdecl;
+  AllocateStringArray: function(Len: NativeInt): Pointer; cdecl;
+  AllocatePointArray: function(Len: NativeInt): Pointer; cdecl;
+
+  SetArrayLength: procedure(TypeInfo: Pointer; var AVar: Pointer; NewLen: NativeInt); cdecl;
+  GetArrayLength: function(AVar: Pointer): NativeInt; cdecl;
+end;
+
+
+

See the Example C++ plugin to see how TypeInfo is used to allocate custom records & arrays.
