[Grammatica-users] Regex Issue

[Alex Jeannopoulos]

Here is a snippet of a grammar I am trying to setup. I am looking to match the following text

PROTO CLIENT EVENT ActiveConversationsList       32 PAYLOAD[JSON(conversations):data] PAYLOAD_DESCRIPTION ""
EVENT_DESCRIPTION "List of ActiveConversations, each ActiveConversation contains conv_id, conv_name, group_id, start_indx, last_indx, uids_involved"
CATEGORY "" CODE (java)
{{{

java example
    aaa
    aaa
    aa

}}}

Here is portion of the grammar I have come up with. 

%tokens%

IDENTIFIER_STRING   = <<[a-zA-Z][a-zA-Z0-9-_]*>>

PAREN_OPEN              = "("

PAREN_CLOSE            = ")"

CODE                            = "CODE"

CODE_TEXT                 = <<(^\{\{\{\n).*(^\}\}\}\n)>>

%productions%

CODE_LANG                = "(" IDENTIFIER_STRING ")";

CODE_DEFINITION     = CODE (CODE_LANG)? CODE_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?

                    ;

[ValidateProtocol] {{{

[ValidateProtocol] [1328:1] unexpected token "{{{" <CODE_BEGIN>, expected <CODE_TEXT>, on line 1328 column: 1

[ValidateProtocol] Error parsing protocol file

As long as I have the CODE_DEFINITION tag in the definition I have errors. What am I missing, 

thanks in advance
