When executing the command:
java -cp antlrworks-1.2.2.jar org.antlr.Tool Expr.g
on a minimal Expr.g file (and any other grammar file with language=Python):
---
grammar Expr;
options {
language=Python;
}
prog:;
---
the following happens:
- the tool exits with error code 1, and writes an error message to the console:
ANTLR Parser Generator Version 3.1.1
error(10): internal error: eval tree parse error : <AST>:0:0:
unexpected AST node:
org.antlr.stringtemplate.language.ActionEvaluator.expr(Unknown Source)
...
...
org.antlr.Tool.main(Unknown Source)
- but the ExprParser.py file is generated just fine.
Is there something wrong in org.antlr.Tool? Or am I doing something wrong?
Regards,
Bernt
