Subject [jira] [Updated] (LUCENE-3151) Make all of Analysis completely independent from Lucene Core
Date Fri, 20 Jul 2012 21:57:33 GMT


Grant Ingersoll updated LUCENE-3151:

    Attachment: LUCENE-3151.patch

Updated version for trunk.  Updated packaging to now include all of Util, as it was getting
ridiculous trying to get the exact list.  I tested this setup by taking the jar produced here,
plus the common analyzers jar and put them in a standalone project and tested them and it
seemed to work.

Thus, I think this is mostly done and ready to commit.  I'd say the only issue left is to
say how we want to document this so that people aren't confused.  My suggestion would be to
collocate a file name README-analyzers-def.txt alongside the jar that explains it.  Otherwise,
we could just put it in the README.

> Lucene's analysis package, including the definitions of Attribute, TokenStream, etc.
are quite useful outside of Lucene (for instance, Mahout uses them) for text processing. 
I'd like to move the definitions, or at least their packaging, to a separate JAR file so that
one can consume them w/o needing Lucene core.  My draft idea is to have a definition area
that Lucene core is dependent on and the rest of the analysis package can then be dependent
on the definition area.  (I'm open to other ideas as well)
