I have a combined grammar (lexer and parser on the same file). How do I set the
filter = true
to the lexer?
Thanks

See http://www.w3.org/TR/speech....
The principle is that you load a main large grammar which has some.
This can be done first with some SRGS grammar files.
It sounds like you need to use some indirection, via the a grammar rule reference.

Is there a simple way to determine wether a grammar is LL1, LR0, SLR1... just from looking on the grammar without doing any complex analysis?
For instance: To decide wether a BNF Grammar is LL1 you have to calculate First and Follow sets first - which...

With that out of the way:
You could write a parser... .
It is perfectly possible to write non-LL(1) grammars for languages for which an LL(1) grammar exists.
A grammar for it, you can only make statements about the grammar itself.

Does anyone have any experience with a tool that generates test strings from a BNF grammar that could then be fed into a unit test?

Processing language (perl/python/etc) to randomly generate sentences from a BNF grammar, and slightly more with this, of course, is that it can only generate strings in the grammar, and unless your grammar-free grammar).

Here's the grammar, which is supposed to describe a language of nested braces with commas as delimiters:
L ::= {L} | L,L |
A few more examples of strings I'd expect the grammar to accept and reject:
Accept:
{,{,,{,}},,{,}} {{{{}}}} {,{}}
Reject:
{}{} ...

::= { L } L 1 | L 1
L 1 ::= ε | , L L 1
First of all, that grammar won't accept your first example.
