[Grammatica-users] Multiline String & repeated terms

[Alex Jeannopoulos]

I am working through 2 issues, that I would like some advise on. Attached is a grammar and protocol files. Within the message are highlights of the grammar.

1. I am attempting to have a repeated term "CODE_DEFINITION", I am getting the following error when the CODE term is repeated.

[29:1] unexpected token "CODE", expected <EOF>, on line 29 column: 1

2. In my regex for a MULTILINE string a double quoted value breaks the parsing. Any thoughts how I can better support a python like multi line string, without escaping quotes within the """ block?

Thanks in advance.

CODE_LANG           = PAREN_OPEN IDENTIFIER_STRING PAREN_CLOSE;

CODE_DEFINITION     = CODE CODE_LANG? TEXT;


EventDefinition   = SERVER_TYPE
                    CODE_TYPE
                    EVENT_TYPE
                    IDENTIFIER_STRING DEC_NUMBER
                    VERSION_TAG?
                    PAYLOAD
                    PAYLOAD_DESCRIPTION_INFO
                    EVENT_DESCRIPTION_INFO
                    CATEGORY_INFO
                    ACTIVE_STATE?
                    CODE_DEFINITION*
                    ;

MULTILINE_STRING                        = <<(^""")([^*]|\*+[^*/])*("""$)>>
QUOTED_STRING                           = <<"([^"]|"")*+">>

TEXT              = QUOTED_STRING | MULTILINE_STRING;
