Re: [Visualpython-users] Problem printing '%' with Text object

[Bruce S. <Bru...@nc...>]

Glad you like the new stuff!

I was aware that & doesn't display in labels on Windows, and I don't
yet know the cause. It does display on Mac and Linux.

The problem with % is a simple mistake, which none of my tests
happened to uncover. In shapes.py the statement

totlen += (vector(contour[j])-vector(contour[j+1])).mag

should read

totlen += (vis.vector(contour[j])-vis.vector(contour[j+1])).mag

You can make this change yourself, and of course it will be
incorporated in future versions. It seems likely that as people try
the new extrusion machinery (and the text object which now shares the
same machinery) they'll find bugs of this kind. I'll wait a little to
see what turns up and then release 5.51. Thanks for the clear report.
