Michael McCandless commented on PYLUCENE-12:
--------------------------------------------
Hmm, one more unfriendliness: if the createComponents method throws an
exception (eg put xxx in there so you hit a NameError), you get back an
exception like this:
{noformat}
======================================================================
ERROR: testReusable (__main__.ReusableAnalyzerBaseTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
File "test/test_ReusableAnalyzerBase.py", line 37, in testReusable
stream = method("test", reader)
JavaError: java.lang.RuntimeException: NameError
Java stacktrace:
java.lang.RuntimeException: NameError
at
org.apache.pylucene.analysis.PythonReusableAnalyzerBase.createComponents(Native
Method)
at
org.apache.lucene.analysis.ReusableAnalyzerBase.reusableTokenStream(ReusableAnalyzerBase.java:73)
{noformat}
Somehow this is missing details (exception cause & TB) of the python source
that caused the exception.... can we fix this? If it's tricky I can open a new
issue...
> Add PythonReusableAnalyzerBase, so we can create analyzers in Python

> Lucene now has a useful helper class, ReusableAnalyzerBase; you subclass it
> and override one method, to create an analyzer that provides
> reusableTokenStream impl.
> I think we should expose it in Python... patch is simple.
