Hi,
what's wrong with the following trivial lexer grammar?
grammar Grammar;
options {
language=Python;
output=AST;
ASTLabelType=CommonTree;
}
prog : .+ ;
I am getting "no viable alternative at character ..." at every character of
input stream.
antlr-3.1.2
Of course I don't really need a 1-char chopping lexer. It is just a relevant
extraction from a real case grammar.
Comments and hints are welcome!
Best regards
