## #590 A new logo for the web sites¶

I worked with Ly on a new logo for the Lino website. #590.

Committed the new logo and my yesterday’s work.

The logo is defined in lino.sphinxcontrib.logo.

## #593 (Write a tkinter based user interface)¶

Tom Radcliffe, in his article Python GUI Programming: wxPython vs. tkinter comes to the conclusion that tkinter is better than wxPython and PyQt because it is by far the quickest: “I feel like the search may be over, and the solution was right under my nose the whole time. I just never paid attention to it because of an outdated and incorrect attitude toward Tcl/Tk and tkinter.”

I never seriously considered tkinter, if I remember well, because it has no built-in datagrid widget.

A user named AruzV asked this in Grid View (Table list) in tkinter, and another user named bvdet posted a nice and working example.

Which reminds me that I have always dreamed of having a second usable user interface for Lino. And a slim quick browser-less desktop application using Tkinter seems to be a cool thing. I opened #593 (Write a tkinter based user interface) so we can at least discuss about priorities.

## #505 : demo data¶

I discovered that the scramble script (see Wednesday, September 9, 2015) had a bug which caused it to produce invalid output.

The bug actually was just that the IBAN list of lino_xl.lib.sepa.fixtures.sample_ibans delivered two empty strings (one at the beginning, the other at the end). I now added a test case to this module which verifies that all IBANs are valid. I removed a few IBANs (those with an unknown country codes) which also triggered a ValidationError.

I replaced the file used by test_import_sepa.

So yes, I “damaged” the xml file when replacing the real data by fictive numbers. But unfortunately this was only a minor detail. The demo file contained many other statements whose IBAN is not empty.

Hamza, so it’s again your turn to work on this! The question remains: Why does it look as if the account number on all statements is missing?

The test_import_sepa case now passes, but the two following lines do not reflect what we want:

self.assertEqual(Account.objects.count(), 1)
self.assertEqual(Movement.objects.count(), 0)


We want to see many accounts and stamtements in our database after importing the file.

I suggest that you analyze that CAMT parser in lino_cosi.lib.sepa.camt and lino_cosi.lib.sepa.parserlib. Maybe the bug is there. Also look at our demo xml file with a browser and compare its content with the parser.

If you have not used lxml before, then you should also read some of these tutorials:

Note that the test suite of Lino Così currently has one failure in file “docs/tested/demo.rst”, line 36. You can ignore this for your work on #505. It is due to my #554.
