[Modeling-users] problem with qualifier parser?

Hi there, long time no see :)

First, sorry for my delay with the cimarron example. I've had to stop
working on cimarron for a while...

Now I'm working with Modeling in zope, and I seem to have come across
a bug... and I'm hoping there's an easy fix (or that it's already
fixed and I've just not seen it on sourceforge :p).

$ python
Python 2.3.3 (#2, Feb 24 2004, 09:29:20)
[GCC 3.3.3 (Debian)] on linux2
Type "help", "copyright", "credits" or "license" for more information.

from Modeling.EditingContext import EditingContext
ec=EditingContext()
ec.fetch('foo', 'orbit > 3')

Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.3/site-packages/Modeling/EditingContext.py", line 1413, in fetch
qualifier=qualifierWithQualifierFormat(qualifier)

return parser.parse(tokens)
File "/usr/lib/python2.3/site-packages/spark.py", line 204, in parse
self.error(tokens[i-1])
File "/usr/lib/python2.3/site-packages/Modeling/QualifierParser.py", line 261, in error
raise ValueError, "Syntax error near token: `%s'" % token
ValueError: Syntax error near token: `<Token OR>'

actually there's the same problem with any token: OR, AND, IN, or
NOT. Is this a known problem in spark? is my spark version wrong?
spark is 0.6.1, Modeling is 0.9-pre-16-patch892454.

Not a problem, 'having a hard time here as well :)

This is a bug, unfortunately not fixed on sf yet :/ I'll have a look at it

from Modeling.Qualifier import *
q=KeyValueQualifier('foo', QualifierOperatorGreaterThan, 3)
print q

(foo>3)

Post by John Lenton

ec.fetch('foo', q)

You can have a look at test_Qualifier.py for other examples.

HTH,

Hi John and all,

You'll find a patch solving the problem along w/ the corresponding
unittests at sf.net, bug #938096:

https://sourceforge.net/tracker/index.php?func=detail&aid=938096&group_id=58935&atid=489335

Thanks for reporting!

-- Sébastien.


PS for Yannick: I still did not find the time to investigate any further
about GNU Arch, but I will, this looks interesting (not to say about
the new name for the framework...!-). Any comparison w/ subversion,
BTW?
