9. Shape Script Syntax

This is the EBNF for Enterprise Architect’s Shape Script language. The start symbol is ShapeScript. Any spaces and tabs between non-terminals are ignored.

ShapeScript = { Shape | Decoration };

Shape = “shape”¹⁵ ShapeName ShapeBody;

ShapeName = /* any reserved or non-reserved string literal depending on the context */;

Decoration = “decoration” Name ShapeBody;

Name = /* an arbitrary string that should describe the form of the decoration */;

ShapeBody = “{“ {InitializationAttributeAssignment} {DrawingStatement} {SubShape} “}”

SubShape = Shape /* with a non-reserved name */;

InitializationAttributeAssignment = Attribute “=” Value “;”;

Attribute = /* see chapter Shape Attributes for a list of values /*;

Value = StringLiteral | Integer | Tuple;

StringLiteral = Quote { Character } Quote;

Quote = /* the double quote “ or a single quote ‘ */;

Character = /* any printable character except the used Quote */;

Integer = [”-“] {“0” .. “9”};

Tuple = “(“ Integer “,” Integer “)”;

Block = “{“ {DrawingStatement} “}” | DrawingStatement;

DrawingStatement = IfElseSection | Method;

IfElseSection = “if” “(“ QueryExpression “)” Block [“else” Block];

QueryExpression = /* see chapter Query Methods for the 2 methods and their parameters */;

Method = /* see chapter Shaping Elements for possible methods and their parameters */;
