Grammar

This grammar was generated from the Parser.jj file using the jjdoc utility from JavaCC. Operators are ordered from lowest to highest precedence (from top to bottom).

Start	::=	( Expression ( <EOF> | <SEMI> ) | ( <EOF> | <SEMI> ) )
Expression	::=	AssignExpression
	|	OrExpression
AssignExpression	::=	( Variable <ASSIGN> Expression )
OrExpression	::=	AndExpression ( ( <OR> AndExpression ) )*
AndExpression	::=	EqualExpression ( ( <AND> EqualExpression ) )*
EqualExpression	::=	RelationalExpression ( ( <NE> RelationalExpression ) | ( <EQ> RelationalExpression ) )*
RelationalExpression	::=	AdditiveExpression ( ( <LT> AdditiveExpression ) | ( <GT> AdditiveExpression ) | ( <LE> AdditiveExpression ) | ( <GE> AdditiveExpression ) )*
AdditiveExpression	::=	MultiplicativeExpression ( ( <PLUS> MultiplicativeExpression ) | ( <MINUS> MultiplicativeExpression ) )*
MultiplicativeExpression	::=	UnaryExpression ( ( PowerExpression ) | ( <MUL> UnaryExpression ) | ( <DOT> UnaryExpression ) | ( <CROSS> UnaryExpression ) | ( <DIV> UnaryExpression ) | ( <MOD> UnaryExpression ) )*
UnaryExpression	::=	( <PLUS> UnaryExpression )

ListExpression	::=	( <LSQ> Expression ( <COMMA> Expression )* <RSQ> )
Variable	::=	( Identifier )
Function	::=	( Identifier <LRND> ArgumentList <RRND> )
