[GRASS-user] Issue with addon r.vif in MS Windows GUI installations (stand-alone v. 7.2.2 and 7.0.5)

[Helmut Kudrnovsky]

>> Did you consider using cStringIO, if you need a file-object?

>> That would avoid the temporary file and thus should be more efficient

>Implemented your patch, thanks.  Dinarzarde, can you test?

tested here in OSGeo4W-winGRASS:

-------------------

to use the new version by g.extension, you have to wait until tomorrow when
the server delivers the precompiled addons for winGRASS.

or just download it manually from

https://trac.osgeo.org/grass/browser/grass-addons/grass7/raster/r.vif

and copy r.vif.py into
