Re: newb questions re python-fu

[paul taney <paultaney@xxxxxxxxx>]

Thanks very much, Chris.

I am using your file now and made a coupla repairs, afaict.
But it still doesnt install.  Now I may know why, as running
it straight up gives  No module named gimpfu!

I am on a Mac.  Did the gimp2.4.5...dmg not compile gimpfu?
Answer may be:  Look for a dot .so file:

find /Applications/Gimp.app/ -name gimpfu\*  |  grep \.so
/Applications/Gimp.app//Contents/Resources/lib/gimp/2.0/python/gimpfu.py
/Applications/Gimp.app//Contents/Resources/lib/gimp/2.0/python/gimpfu.pyc
/Applications/Gimp.app//Contents/Resources/lib/gimp/2.0/python/gimpfu.pyo
                                   ==
false positive.

What should I do next?

...is still the case.  I am also pushing it twice, like:
  % cp python-fu-vanderwalt.py ~/.gimp-2.4/plug-ins
  % chmod +x ~/.gimp-2.4/plug-ins/python-fu-vanderwalt.py
  % cp python-fu-vanderwalt.py ~/gimp/gimp-2.4.7/plug-ins/pygimp/plug-ins
  % chmod +x ~/gimp/gimp-2.4.7/plug-ins/pygimp/plug-ins/python-fu-vanderwalt.py
