Thanks. I'll look to test some other use cases that were difficult in
the past, particularly some advanced styles. FYI as things were as
of this morning, none of my code base needed changes to function,
which as you'd imagine is a relief -- and all the style error warnings
are now gone, too.

I've updated the save routines in my example to match yours and
the new API as well.

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

Note that I changed the blessed saving api.

OK, I've completed my sample application. It's a simple data collection
program that
gets the current bitcoin price and appends it to a spreadsheet. Appears
to work so far
on Morten's updated version as of this morning.
It can be found at:

https://github.com/deanmccarron/gnumeric-python-examples/blob/master/python-gnumeric-example.py

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.
Hopefully
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 "t3002-introspection-io.py", 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
install"
might help.

Also using your test program, as is I get an error when it hits the
sheet.cell_set_value
operation, saying it got 3 variables instead of the 2 expected. When I
change it to two, I get:
TypeError: argument cell: Expected Gnm.Cell
So it's expected a Gnm.Cell and not the col, row provided in the
program.
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
  Â
https://git.gnome.org/browse/gnumeric/tree/README-introspection
although that file may move.  This file also contains
the "blessed"
API.
This is still evolving.

My main test script is at
  Â

https://git.gnome.org/browse/gnumeric/tree/test/t3001-introspection-simple.py
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
