I don't know if I'm dumb, ignorant, inexperienced, or asleep but while I can sometimes beat a plugin into submission, once I have setup.py working I treat it with superstition and reverence, unable to change anything with a plan or with confidence that it will do the right thing. I've looked and asked and I have never gotten a pointer to a clear explanation of what to put in it. Help!
I'm working my IQueryPreprocessor (http://trac.edgewall.org/ticket/10983) I'm now trying to port my ExtensionPoint in 0.11.6 to an OrderedExtensionsOption in 1.0 (or 1.1 or whatever the development branch is). In 0.11.6, I can test my changes to query.py with my TracPM code but that's not ported to or tested in 1.0 yet so I figured I'd just put together a trivial implementation to illustrate and test the interface (at the end of this message). My example translates "foo" to "id" so [[TicketQuery(foo=1)]] is the same as [[TicketQuery(id=1)]] and [[TicketQuery(id=1|2,foo=3)]] is the same as [[TicketQuery(id=1|2|3)]]. I put my code in trac/sample-plugins/sampleQueryPreprocessor/sampleQueryPreprocessor.py and tried and tried to create a setup.py in that directory. Nothing I try works. I build my egg and deploy it and my trac.log says: 2013-01-21 15:45:27,463 Trac[loader] DEBUG: Adding plugin SampleQueryPreprocessor 0.1 from /opt/trac/trac1.0/plugins/SampleQueryPreprocessor-0.1-py2.7.egg 2013-01-21 15:45:27,470 Trac[loader] DEBUG: Loading SampleQueryPreprocessor from /opt/trac/trac1.0/plugins/SampleQueryPreprocessor-0.1-py2.7.egg 2013-01-21 15:45:27,473 Trac[loader] ERROR: Skipping "SampleQueryPreprocessor = SampleQueryPreprocessor": Traceback (most recent call last): File "build/bdist.linux-x86_64/egg/trac/loader.py", line 68, in _load_eggs entry.load(require=True) File "build/bdist.linux-i686/egg/pkg_resources.py", line 1954, in load entry = __import__(self.module_name, globals(),globals(), ['__name__']) ImportError: No module named SampleQueryPreprocessor My setup.py (modeled on something else I found on my disk that I think works) is: #!/usr/bin/env python # -*- coding: iso-8859-1 -*- from setuptools import find_packages, setup setup( name = 'SampleQueryPreprocessor', author = 'Chris Nelson', author_email = 'chris.nel...@sixnet.com', description = 'Example of a IQueryPreprocessor implementation', version = '0.1', license='BSD', packages=find_packages(exclude=['*tests*']), entry_points = """ [trac.plugins] SampleQueryPreprocessor=SampleQueryPreprocessor """, ) What should it be?
