Hi Folks
I have a production in a tree grammar with ST output
rule
: ^(AS_RULE rName=ID rType=ID alternative+)
;
What I'd like is to pass in all the STs from the 'alternative' matches into a
single multi-valued attribute for the ST for this production, like so
rule
: ^(AS_RULE rName=ID rType=ID alternative+)
-> someTemplate(rName={$rName.text}, alts={ ??? })
;
where alts iis a multi-valued attribute consisting of STs. I know I can do this
rule
@init { List<StringTemplate> alts = new ... }
: ^(AS_RULE rName=ID rType=ID ( a=alternative { alts.add($a.st); } )+ )
-> someTemplate(rName={$rName.text}, alts={ alts })
;
but this seems clumsy. Is there any better way?
Thanks.
