Re: [Jflex-devel] 1.7 release?

[Gerwin K. <kl...@un...>]

Makes sense. Could you add these to the github tracker, please?

7) and 9) are no problem.

8) is interesting. I’d probably try to change the rules instead to avoid indefinite lookahead, but in a large grammar that might not make sense. In any case, it shouldn’t be hard to configure fixed buffers.

This does change the semantics, though: in the Lucene case, the long rule never matches, but if the input was different, it could - and then the scanner with fixed buffer matches different tokens to the one with growing/unbounded buffer. I don’t think it’s a huge problem, but we should document it clearly.

Cheers,
Gerwin
