I decided it would be worthwhile to have a csv module written in Python (no
C underpinnings) for a number of reasons:
* It will probably be easier to add Unicode support to a Python version
* More people will be able to read/grok/modify/fix bugs in a Python
implementation than in the current mixed Python/C implementation.
* With alternative implementations of Python available (PyPy,
IronPython, Jython) it makes sense to have a Python version they can
use.
I'm far from having anything which will pass the current test suite, but in
diagnosing some of my current failures I noticed a couple test cases which
seem wrong. In the TestDialectExcel class I see these two questionable
tests:
def test_quotes_and_more(self):
self.readerAssertEqual('"a"b', [['ab']])
def test_quote_and_quote(self):
self.readerAssertEqual('"a" "b"', [['a "b"']])
It seems to me that if a field starts with a quote it *has* to be a quoted
field. Any quotes appearing within a quoted field have to be escaped and
the field has to end with a quote. Both of these test cases fail on or the
other assumption. If they are indeed both correct and I'm just looking at
things crosseyed I think they at least deserve comments explaining why they
are correct.
Both test cases date from the first checkin. I performed the checkin
because of the group developing the module I believe I was the only one with
checkin privileges at the time, not because I wrote the test cases.
Any ideas about why these test cases are in there? I can't imagine Excel
generating either one.
Thx,
