Error Parsing the VB BNF

[Doug Morris]

I downloaded the latest version of Gold Parser (5.01) and tried to
build the VB.NET grammar from hte same website and it fails due to and
error with the Comment Line entry.

Does anyone have any ideas?

Thanks in advance.

Ah. I need to go through the grammar page tonight and update any line/
block comments that changed in 5.0. In 5, group definitions, such as
Comment Line, only specify a terminal name rather than a regular
expression. This was necessary since multiple groups can share the
same ending terminal.

Anyway, you can update the grammar as follows:

CommentSymbol = '' | Rem

Comment Line = CommentSymbol

... or... you can create two groups. 'Comment' is automatically
defined as noise. But, our second one will have to be set manually:

Comment Line = ''
Rem Line = rem

Rem @= {type = noise}

Now there are two line-based groups: Comment Line and Rem Line. The
container for Comment Line is 'Comment' and Rem Line is 'Rem'. Both
are noise, and will be ignored.
