[Clucene-perl] Further Development of the perl library of Lucene

[Erik W. <eri...@iq...>]

Hello *,

I'm interested in the development of clucene, especially in the perl port. It 
seems that the existing perl modules are either a complete port
(http://search.cpan.org/dist/Plucene/) or very outdated
http://search.cpan.org/~pedwards/CLucene-1.00/CLucene.pm (from 2005).

Even the perl binding mentioned on our homepage 
http://search.cpan.org/~tbusch/Lucene-0.18/lib/Lucene.pm are from 2007.

Compiling the perl binding with the source from clucene 2.3.3.4 failed with 
the follwing error messages:

In file included from Lucene.xs:22:0:
/usr/local/clucene/include/CLucene/util/Reader.h:13:2: error: #error Reader 
has been refactored. It is recommended that you use strigi streams
/usr/local/clucene/include/CLucene/util/Reader.h:14:2: error: #error for all 
input into CLucene. If, however, you dont want to use that dependency,
/usr/local/clucene/include/CLucene/util/Reader.h:15:16: warning: missing 
terminating ' character [enabled by default]
/usr/local/clucene/include/CLucene/util/Reader.h:15:2: error: #error then 
you'll have to refactor your current code. The jstreams namespace
/usr/local/clucene/include/CLucene/util/Reader.h:16:2: error: #error was 
completely removed
In file included from Lucene.xs:75:0:
cpp/Tokenizer.cpp:13:14: error: conflicting return type specified for ‘virtual 
bool PerlTokenizer::next(Token*)’
...etc...

There were nearly two pages of error messages. So I think this part needs some 
refactoring. B-)

And there is this old thread "[Clucene-perl] Is Lucene.pm dead ?" from this  
mailing list 
(https://sourceforge.net/mailarchive/forum.php?thread_name=4D6692DB.30508%40tablix.org&forum_name=clucene-
perl).

So my questions are:
1) Is there active development of the perl library for the current version of 
clucene? (I guess 'no').
2) How hard are the changes to update the perl stuff from from supporting 
clucene 0.9.X to  2.3.X?
3) Can/Should I do it? Are they any hints/help/on this issue? Have some other 
tried it?

So long... Erik

Note the PLucene is a pure-Perl port of Lucene and has nothing to do
with CLucene. And AFAIK CLucene developers don't have anything common
with the group that develops the original (Java) Lucene.

No. I tried contacting the maintainer listed on CPAN and got no replies.

You should find a changelog (if it exists) or contact the CLucene
developers about this.

I am still using CLucene in some of my projects. I can contribute a few
patches, if you decide to update it.

Also note that Debian still ships CLucene 0.9.21 (which is the reason
I'm still able to use it with Perl). I don't know about other distributions.

Best regards
