Inkscape unsaved file issue

[jfowlie]

I wonder if it is possible to add a test to see if the file has been saved in Inkscape before attempting to generate the paths to OpenSCAD. I just spent an hour trying to walk the code (and I don't know Python), only to realize that I had not saved the file I had created in Inkscape before trying to export to OpenSCAD.

I kept getting these errors:
Traceback (most recent call last):
File "paths2openscad.py", line 1430, in
e.affect()
File "/usr/share/inkscape/extensions/inkex.py", line 283, in affect
self.effect()
File "paths2openscad.py", line 1213, in effect
self.handleViewBox()
File "paths2openscad.py", line 594, in handleViewBox
if self.getDocProps():
File "paths2openscad.py", line 580, in getDocProps
self.inkscape_version = re.sub(" *(unknown) *", "", inkscape_version)
File "/usr/lib/python2.7/re.py", line 155, in sub
return _compile(pattern, flags).sub(repl, string, count)
TypeError: expected string or buffer

Thanks for your work on this! I hope to make a lot more use of it.

hey. indeed happened to me too fequently. The dirty quick fix is to change

self.inkscape_version = re.sub(" *(unknown) *", "", inkscape_version)

to

self.inkscape_version = "0.92.4"

then it works. regards, Mario

okay might be more complex, because this is belonging to #1
