Cannot find rule for token about bullwinkle HOT 3 CLOSED

Hi Martijn,

First, thanks for your interest in Bullwinkle! I think the problem is that your BNF file uses ::= instead of := to separate the non-terminal symbol from its cases. Try that and let me know if this fixes your problem.

On a side note, I see that the grammar defines rules down to the level of single characters, for example to define the format of a valid identifier. BW was designed to parse whitespace-separated sequences of words, so I'm not sure this is a good fit for it. This could probably be better represented in Bullwinkle as a regex that defines the format of a particular word.

Best!

Thanks! Changing ::= to := solved the error message, but now the parser produces a null object.

Now that I'm reading the instructions more thoroughly I see that Bullwinkle support only the basic BNF syntax, and not fancy things like optional elements [] and repetition * like mentioned here. I guess those are not on the development path for Bullwinkle?
