Hello There,

I am creating an editor for the SMI format. See:
http://en.wikipedia.org/wiki/Structure_of_Management_Information

It's used to define so called MIB's used by the SNMP protocol. The SMI format is based on ASN1.
There is a antlr version of the grammar as a starting point, but that is horrifically intimidating Smile

http://www.antlr3.org/grammar/1105770765162/parsesmi-v1-15jan05.zip

Does anyone has a base ASN1 Xtext grammar or even better SMI? If not, would anyone like to cooperate on this? Or help translate the antlr grammar?

For example in ANTLR, this grammar as a bunch of tokens as :

tokens {
	
ABSENT_KW = "ABSENT" ;
ABSTRACT_SYNTAX_KW = "ABSTRACT-SYNTAX" ;
ALL_KW= "ALL" ;
ANY_KW = "ANY" ;
ARGUMENT_KW = "ARGUMENT" ;
APPLICATION_KW = "APPLICATION" ;
AUTOMATIC_KW = "AUTOMATIC" ;
BASED_NUM_KW = "BASEDNUM" ;
BEGIN_KW = "BEGIN" ;
BIT_KW = "BIT" ;
BMP_STRING_KW = "BMPString" ;
...
}


How do I convert this to Xtext? Are these literals which can be put in an enum?
I will be facing more of these issues, and need help.

Thank You.

Hi Christophe,

those token definitions can be translates as plain keywords.

Hi Sebastian,

Thanks for offering me to pay you Wink

Anyway, I made a start and quiet happy with the result sofar (At least it compiles). Anyplace where we share xtext grammars?
