| List of errors not included in or not apparent from the XBGF files: | ||
| - lacking terminator symbol by NUMBER, assertStatement, scriptTag, libraryName | ||
| - constOb jectExpression => constObjectExpression | ||
| - things like ’;’ instead of ‘;’ in many terminals | ||
| - ‘, instead of ‘,’ (or ’,’) in formalParameterList | ||
| - ’) instead of ’(’ (or ‘(’) in libraryImport | ||
| - getterSignature and setterSignature contain "static" not in bold | ||
| - interfaceDefinition contains "interface" not in bold | ||
| - hyphenation in nonterminal names in | ||
| factoryConstructorSignature | ||
| mapLiteral | ||
| relationalExpression | ||
| additiveExpression | ||
| interfaceDefinition | ||
| functionExpression | ||
| topLevelDefinition | ||
| scriptDefinition | ||
| libraryDefinition | ||
| - The last two alternatives are just wrong, incorrectly understood from ANTLR spec: | ||
| SINGLE LINE STRING: | ||
| ‘”’ STRING CONTENT DQ* ‘”’ | ||
| | ‘’’ STRING CONTENT SQ* ‘\’’ | ||
| | ‘@’ ‘’’ ( ( ‘’’ | NEWLINE ))* ‘’’ | ||
| | ‘@’ ‘”’ ( ( ‘”’ | NEWLINE ))* ‘”’ | ||
| ; | ||
