[antlr-interest] importVocab exportVocab problem

[hawkwall]

Hello,

I am having trouble defining a vocabulary in one file and the
importing it into my Parser.  I have read the documentation and
everything I can find in the newgroup, plus have gone through the
TinyBasic example and I am still getting errors.  Sorry, this seems
like it should be easy.

I started by defining a lexer and parser in the same file.  When I did
this, my example ran.  I then created another grammar file, moved my
lexer to this file, added an exportVocab option.  In the original
file, I deleted the lexer and added an importVocab option to the
parser.  Compiling the lexer first and then the parser, I see the
tokens are generated in the ParserTokensTypes.txt, but I get the
following error:

line 1:1: expecting "MIKE.START", found 'MIKE.START'

Here is the Lexer:
class mikeLexer extends Lexer;

options {
	testLiterals=true;
	exportVocab=mike;
}

protected
DIGIT : ('0'..'9') ;

protected
DOT : '.' ;

protected
INTEGER : (DIGIT)+ ;


protected
DECIMAL : (DIGIT)*  DOT (DIGIT)+ ;

NUMBER : 	((DIGIT)* DOT)=> (DIGIT)* DOT (DIGIT)+ 
				{$setType(DECIMAL);} 
			| (DIGIT)+ 
				{$setType(INTEGER);}
		;

protected
LETTER : 'A'..'Z';

TAG : (LETTER | DOT)+ ;		


WS	:	(	' '
		|	'\t'
		|	'\f' 
		|	(	options {generateAmbigWarnings=false;}
			:	"\r\n"  // DOS
			|	'\r'    // Macintosh
			|	'\n'	// Unix
			)
			{newline();}
		)+

    // now the overall whitespace action -- skip it!
    { $setType(Token.SKIP); }
    ;

Here is the parser:
class P extends Parser;

options {
	k=2;
	importVocab=mike;
}

startRule	:	"MIKE.START"
				INTEGER
				"END.MIKE"
    ;


Here is the input file:
MIKE.START
100
END.MIKE

My goal is be able to share this Vocabulary with multiple Parsers, at
times extending the tokens.  What am I missing? Thanks for your time.
