[jira] Created: (LUCENE-2699) Update StandardTokenizer and UAX29Tokenizer to Unicode 6.0.0

[David Eric Pugh (Jira)]

Update StandardTokenizer and UAX29Tokenizer to Unicode 6.0.0
------------------------------------------------------------

                 Key: LUCENE-2699
                 URL: https://issues.apache.org/jira/browse/LUCENE-2699
             Project: Lucene - Java
          Issue Type: Improvement
          Components: contrib/analyzers
    Affects Versions: 3.1, 4.0
            Reporter: Steven Rowe
            Assignee: Steven Rowe
            Priority: Minor
             Fix For: 3.1, 4.0


Newly released Unicode 6.0.0 contains some character property changes from the previous release (5.2.0) that affect word segmentation (UAX#29), and JFlex 1.5.0-SNAPSHOT now supports Unicode 6.0.0, so Lucene's UAX#29-based tokenizers should be updated accordingly.

Note that the UAX#29 word break rules themselves did not change between Unicode versions 5.2.0 and 6.0.0.

-------------------------------------

+1

does the minimal jflex revision need to be bumped (currently r591 in READ_BEFORE_REGENERATING.txt) ?

Yes, it should be bumped to r597.  I post a patch including that shortly. Thanks for the review, Robert.

Steven Rowe updated LUCENE-2699:
--------------------------------

    Attachment: LUCENE-2699.patch

The previous patches were generated on WinVista under Cygwin using a native Windows client (SlikSVN) -- apparently that isn't a good idea - mixed end-of-line styles run rampant (and rampant, whatever it is, can't be good).

This version of the patch *really* doesn't have mixed end-of-line styles.  I used the Cygwin svn client this time, and all end-of-lines are LF.

I plan on committing shortly.
