Re: how to convert VB scripts to Gnumeric python

I have added column/row size to my todo list.

Note that I changed the blessed saving api.

It can be found at:

In writing it I stumbled into at least one wish-list item, which is a
blessed set of
function calls for formatting row and column widths/heights. I played
around with
doing some kind of class inheritance on the workbook object to add file
I/O using
methods, but my python-fu is weak.

I wrote in a pretty verbose commentary style, it should be fairly easy
to follow what
I'm doing. It's not especially pretty Python code, but it is exactly
what I wished I had
when I started down my VB to Gnumeric conversion more than a year ago.
this, the patches and the massive amount of work Morten on the
introspection interface
as well as his examples will make life a lot easier for those that follow.

This was added since 1.12.32, presumably installing yelp-tools will
fix this?

Commented it out and I'm up an running. I also updated goffice for
good measure.

basic and simple tests pass now with no issue. On io test I'm getting:

Traceback (most recent call last):
  File "", line 25, in <module>
    wbv = Gnm.WorkbookView.new_from_uri (src_uri, None, ioc, None)
TypeError: constructor returned NULL

The plugin test is failing as well, but this is very likely due to me
missing some components (I only use Gnumeric, not gnome) and this
isn't an especially great concern in my use case.

That's a sign you're picking up an old introspection file. "make
might help.

I suspect I'm probably testing a bit ahead of your patches on github.

This appears to be happening on the line

s_wbv=Gnm.WorkbookView.new_from_uri(s_uri, None, io, None)

Which is the actual workbook file open read. Though this may just be
me (perhaps I need to update other libraries?)

This worked on goffice-0.10.32 with the patches I'd used on gnumeric.
So we'll need to sort out what changed.

You can follow the battle at
although that file may move.  This file also contains
the "blessed"
This is still evolving.

My main test script is at

It does pretty much everything one can do to a workbook other than
file i/o.
(That's somewhere on my list.)

Note: I have marked lots of functions as "skip" because they are
low-level functions
not intended for scripting.  Most of GnmCell's methods
are like
that.  They don't do
what you would expect of them and there are proper alternatives,
typically in Sheet.Â
