Editor Macros PascalScript

From Free Pascal wiki

English (en) русский (ru)

General

The PascalScript macro functionality is available in Lazarus 1.1 and later. To use the feature you have to install the package EditorMacroScript, which includes the Pascal Script package. Pascal Script is provided by REM Objects. A minimum package is provided with the Lazarus 1.1 distribution.

Availability

This functionality is only available on selected platforms/architectures:

  • Windows
    • 32/64bit Intel/AMD
  • Linux
    • 32/64bit Intel/AMD
  • Mac
    • 32(/maybe 64)bit Intel/AMD
    • 32bit PPC

Simple actions

All simple Keyboard actions are represented as follows:

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

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

Functions

    Function InputQuery( const ACaption, APrompt: string; var Value: string): Boolean;

Objects provided

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

Caller: TSynEdit

The following methods and properties are available:

Caret
    property CaretX: Integer;
    property CaretY: Integer;
    property CaretXY: TPoint;
    property LogicalCaretXY: TPoint;
    property LogicalCaretX: Integer;
    procedure MoveCaretIgnoreEOL(const NewCaret: TPoint);
    procedure MoveLogicalCaretIgnoreEOL(const NewLogCaret: TPoint);
Selection
    property BlockBegin: TPoint;
    property BlockEnd: TPoint;
    property SelAvail: Boolean; // read only
    property SelText: string;
    property SelectionMode: TSynSelectionMode;
    procedure ClearSelection;
    procedure SelectAll;
    procedure SelectToBrace;
    procedure SelectWord;
    procedure SelectLine(WithLeadSpaces: Boolean);
    procedure SelectParagraph;
Search/Replace
    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,
      ssoBackwards,
      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)
  end;
Text
    property Lines[Index: Integer]: string; // read only
    property LineAtCaret: string;  // read only
    procedure InsertTextAtCaret(aText: String; aCaretMode : TSynCaretAdjustMode);
    property TextBetweenPoints[aStartPoint, aEndPoint: TPoint]: String              // Logical Points
    procedure SetTextBetweenPoints(aStartPoint, aEndPoint: TPoint;
                                   const AValue: String;
                                   aFlags: TSynEditTextFlags = [];

                                  );
Clipboard
    procedure CopyToClipboard;

    procedure PasteFromClipboard;
    property CanPaste: Boolean     // read only
Logical / Physical
    function LogicalToPhysicalPos(const p: TPoint): TPoint;
    function LogicalToPhysicalCol(const Line: String; Index, LogicalPos

    function PhysicalToLogicalPos(const p: TPoint): TPoint;
    function PhysicalToLogicalCol(const Line: string;
                                  Index, PhysicalPos: integer): integer;

Column Align Source code

A macro that aligns selected code to a specific token. It looks for a specific token in each selected line, and aligns each occurrence of it.

Select the 3 lines. If the selection starts right before the ":" then the ":" will be detected. A prompt will ask you to confirm the ":". Then all ":" will be aligned. (If you use a word for alignment, please note, that it will be matched regardless of word boundaries)

You can vertically align things like := or // or (

  foo := 1;
  something := 2;
  x := -3;
  foo       := 1;
  something := 2;
  x         := -3;

Count array elements

A macro to count the boundaries in an array constant.


  const foo: array [0..] of integer = (
    1, 2, 3,
    4
  );
  const foo: array [0..3] of integer = (
    1, 2, 3,
    4
  );

See http://forum.lazarus.freepascal.org/index.php/topic,27186.msg167883.html#msg167883 for counting array elements.


Add PasDoc for function declaration

Comments a procedure/function in PasDoc format

Example: Executing the macro with the caret in the line of function declaration will insert the comment before.

function AddRadioButton(const aCaption: string; aChecked: boolean = False): TCheckBox;
{ Description
  @param(aCaption description )
  @param(aChecked description )
  @returns( description )
  @raises( none )
}
function AddRadioButton(const aCaption: string; aChecked: boolean = False): TRadioButton;

Sort selected lines

There are two macros, one with the normal alphabetical order and another that orders by type

  c:integer;
  b:integer;
  d:boolean;
  a:boolean;
  //normal sorting
  a:boolean;
  b:integer;
  c:integer;
  d:boolean;
  //sorting by type
  d:boolean;
  a:boolean;
  c:integer;
  b:integer;
