[antlr-interest] Problems parsing a file

[Dmitri Pissarenko]

Hello!

I have a file, which I want to parse (TaskJuggler III bookings file) and a
grammar for it.

When trying to parse it, I get following errors:

line 1:42 mismatched character '-' expecting set '0'..'9'
line 1:48 mismatched character ':' expecting set '0'..'9'
line 1:52 mismatched character '+' expecting set '0'..'9'
line 1:59 mismatched character ' ' expecting set '0'..'9'

at line

> project prj "Sample project" "1.0" 2010-10-24-00:00-+0200 -
2010-11-23-09:00-+0100 {


Here are parts of the grammar, which are relevant for this line:

GRAMMAR (START)
bookingsFile returns [DefaultBookingsFile bookingsFile]
    :
        {
            bookingsFile = new DefaultBookingsFile();
        }
        projectHeader
        projectIds
        (resourceDeclaration)*
        (task)*
        (
            suppStmt=supplementStatement
{bookingsFile.addSupplementStatement( $suppStmt.suppStmt ); }
        )*
    ;

projectHeader
    :
        'project prj "' ANY_TEXT '" "1.0"' TJ3_BOOKING_TIME '-'
TJ3_BOOKING_TIME '{'
        '}'
    ;
TJ3_BOOKING_TIME
    : DIGIT DIGIT DIGIT DIGIT '-' DIGIT DIGIT '-' DIGIT DIGIT '-' DIGIT
DIGIT ':' DIGIT DIGIT '-' TIMEZONE
    ;
TIMEZONE
    : ('+'|'-')DIGIT DIGIT DIGIT DIGIT
    ;
GRAMMAR (END)

What's wrong with this grammar?

Thanks in advance

Dmitri
