This includes the PascalScript package. PascalScript is provided by REM Objects. A minimum package is provided with the Lazarus 1.1 distribution.

Simple actions

All simple Keyboard actions are represented as follows.

Move Caret one to the left (in the editor that invoked the macro)
Inserts an 'a'

See the unit SynEditKeyCmds in pacckage SynEdit, and IDECommands in IDEIntf for a full list. Or use the Recorder to get the names of actions.

Objects provided

Scripts can refer to the invoking SynEdit via the identifier "Caller".

The following methods and properties are available:

   property CaretX: Integer;
   property CaretY: Integer;
   property CaretXY: TPoint;
   property LogicalCaretXY: TPoint;
   property LogicalCaretX: TPoint;
   property BlockBegin: TPoint;
   property BlockEnd: TPoint;
   property SelAvail: Boolean; // read only
   property SelText: string;
   property SelectionMode: TSynSelectionMode;
   property Lines[Index: Integer]: string; // read only
   property LineAtCaret: string;  // read only
   function SearchReplace(const ASearch, AReplace: string; AOptions: TSynSearchOptions): integer;
   function SearchReplaceEx(const ASearch, AReplace: string; AOptions: TSynSearchOptions; AStart: TPoint): integer;
   TSynSearchOptions = set of
   ( ssoMatchCase, ssoWholeWord,
     ssoEntireScope, ssoSelectedOnly,  // Default is From Caret to End-of-text (or begin-of-text if backward) 
     ssoReplace, ssoReplaceAll,        // Otherwise the function does a search only
     ssoPrompt,                        // Show the prompt, before replacing
     ssoSearchInReplacement,           // continue search-replace in replacement (with ssoReplaceAll) // replace recursive
     ssoRegExpr, ssoRegExprMultiLine,
     ssoFindContinue                   // Assume the current selection is the last match, and start search behind selection
                                       // (before if ssoBackward) // Default is to start at caret (Only SearchReplace / SearchReplaceEx has start/end param)

Returns the number of replacements done. When Searching, returns 1 if found, 0 if not found. If found the match will be selected (use BlockBegin/End).

 if Caller.SearchReplace('FindMe', ' ', []) > 0 then begin
   // Selection is set to the first occurrence of FindMe (searched from position of caret)
