I'm writing XText grammar for Markdown syntax. In markdown the h1 can be written with #heading.
So, Heading can match anything other than a newline character.
grammar org.example.domainmodel.DomainModel with org.eclipse.xtext.common.Terminals
generate domainModel "http://www.example.org/domainmodel/DomainModel"
DomainModel:
(elements += Element)*
;
Element:
Section1 | Section2
;
Section1:
'#' name += HEADING '\n'
;
Section2:
'##' name += HEADING '\n'
;
terminal HEADING: (('A'..'Z') | '_'| ('a'..'z') | ('0'..'9') | '-')* ;
But this gives error as :
The following token definitions can never be matched because prior tokens match the same input: RULE_INT
Also, heading cannot have any special characters with this.
What is correct way of writing this grammar?
instead of using a new terminal rule HEADING, use terminal rule ID which is already defined:
Section1:
'#' name = ID '\n'
;
Section2:
'##' name = ID '\n'
;
