Re: Ruby & Lucene & ApacheCon

Thomas - have you had a look at PyLucene and how they do the gcj/SWIG
wizardry? What kinds of issues did you encounter with gcj? Perhaps
Andi Vajda from PyLucene could offer some advice?
I'd rather see the gcj/SWIG approach moving forward so that SWIG
Lucene doesn't lag behind Java Lucene where all the innovation happens.
As for Lucene4C versus CLucene and moving CLucene to Apache - I'll
let the c-dev[at]lucene list discuss it. I'm happy to have CLucene at
Apache too, though it seems simpler for us to only house a single
implementation in C. The gcj version would be ideal in my mind, but
I'm also not skilled in gcj (and haven't touched C in decades,
practically) - so it certainly is up to the actual coders where to go
with it.
