Re: gobject-introspection for Gnumeric [Was: Python headers for pygobject 3/Gnumeric 1.12.25]

I don't know for Ruby, but with Python, you can do something like:

$ python

Due to poor naming conventions in gnumeric, the last line is not
wv.save_as(fs,uri,cc)

That will have to be enhanced in next version.

Hope this helps,
