Hello,
I'm trying to port the sculture framework to Xtext Version 1.0.1 and have an
issue with Sculptordsl.xtext:
Output of the GenerateSculptordsl.mwe:
warning(205):
../org.xtext.example.mydsl.ui/src-gen/org/xtext/example/mydsl/ui/contentassist/antlr/internal/InternalMyDsl.g:1:8:
ANTLR could not analyze this decision in rule Tokens; often this is because
of recursive rule references visible from the left edge of alternatives.
ANTLR will re-analyze the decision with a fixed lookahead of k=1. Consider
using "options {k=1;}" for that decision and possibly adding a syntactic
predicate.
warning(209):
../org.xtext.example.mydsl.ui/src-gen/org/xtext/example/mydsl/ui/contentassist/antlr/internal/InternalMyDsl.g:32917:1:
Multiple token rules can match input such as "'w'": T129, RULE_ID,
RULE_ANY_OTHER
As a result, tokens(s) RULE_ID,RULE_ANY_OTHER were disabled for that input
warning(209):
../org.xtext.example.mydsl.ui/src-gen/org/xtext/example/mydsl/ui/contentassist/antlr/internal/InternalMyDsl.g:32917:1:
Multiple token rules can match input such as "'>'": T25, RULE_ANY_OTHER
As a result, tokens(s) RULE_ANY_OTHER were disabled for that input
...
The warning results in erroneous auto-completion in the generated DSL
Editor.
After some experiments with reducing the Xtext grammar I realized that
removing either "attributes" or "references" in the grammer rule
"DslCommandEvent" fixes the warning but some Xtend generator templates gets
broken.
What can be wrong with the grammar? There are no problems with Xtext 0.7.X
and same grammar.
I think this question is rather to Xtext/ANTLR experts.
May be there are such experts here?
