Using CLucene

[Oliver Cromm]

As Lucene is not ported yet to Ruby, can I use CLucene (or another
version) for the time being?

I'm not a Real Programmer[TM] and don't have an idea about how you call
C++ from Ruby (I can't use gcc without explicit instructions, so
README.EXT is quite a hard read for me). It seems that you have to
write some kind of 'wrapper'.

Or does that amount to 'porting Lucene to Ruby' already?

I am looking to do the same thing, but fwiw, calling C (haven't tried
C++) from ruby is pretty straightforward via ruby/dl. Not sure how
straightforward CLucene's api is for this, though.

I won't have a chance to hack around before I leave on vacation later
this week, but once I hack around a bit will post my results.

well, you can use the ruby/dl module to wrap c libraries withouth c, in
pure ruby.. maybe this helps

The other option is to take the PyLucene work and make a SWIG interface
file for Ruby... getting CLucene to build is... entertaining ;-)

There's a Ruby/Lucene project by Erik Hatcher, but it seems to be
stalled, no releases so far, only available thorough cvs at:
http://rubyforge.org/projects/rubylucene

Maybe you should mail Erik and ask him if he's still interested for
team-up or you to take over.
It'd be nice to have a tool like this.

Swigging and writing an extension for something like this should be
IMHO the second step after having a good understanding of how the
thing works under the hood, especially if you claim not to be an
experienced programmer.

Anything, but please, No py-thing, please ;-)

cheers,

Did, he is the one who suggested I look into PyLucene ;-)

Is there any real advantage to using swig over ruby/dl? (Genuine
question - I don't know either way.)

well, you can even do what the OSAF guy did: take the original lucene,
compile it to native code with gcj, then use python bindigns with that..

don't ask me why.

Hey, it comes in handy that I read Japanese, so I have access to the
tutorial ... I'm not going to do much soon on this, though, the whole
project I want it for (an archiving system) is lagging behind by
months.
