#3152: g.gui.animation issues with stvds and list of vector maps
-----------------------------+-------------------------
 Reporter:  veroandreo       |      Owner:  grass-dev@…
     Type:  defect           |     Status:  new
 Priority:  normal           |  Milestone:  7.2.0
Component:  wxGUI            |    Version:  svn-trunk
 Keywords:  g.gui.animation  |        CPU:  Unspecified
 Platform:  Linux            |
-----------------------------+-------------------------
 I want to create an animation for a weekly STVDS covering a total time
 span of 5 years. However, the STVDS only consist of 62 maps, given that
 there's no data in every week but only in those 62 weeks (summer weeks
 over the years).

 When I pass my STVDS to g.gui.animation (using the GUI or the
 CLI), I either get a lot of black screens for those time periods in which
 my STVDS has no maps or the last map with data remains there until a new
 map with data comes. Is there a way to only get the background raster in
 those periods without data, instead of the last vector with data???
 As these are cases of a disease, it has no sense (and it represents
 something that it is not true) to keep the last point for an X period of
 time until new cases appear.

 I thought that maybe only passing the list of 62 maps (not as a time
 series) would suffice, but I found I cannot use '?' in the GUI for
 the selection, and then I have to manually click on maps with no
 possibility to scroll. Is it feasible to add support for
 the '?' or a file parameter, as in other modules, to pass a file with the
 list of maps?

 The next thing I tried was to pass the list of files with the CLI, using

 {{{
 g.gui.animation vector=`g.list type=vector mapset=.
 pattern=cases_20??_??_??_* separator=comma`
 }}}

 but I get the following error:

 {{{
 Traceback (most recent call last):
   File "/home/veroandreo/software/grass-7.3.svn/dist.x86_64-pc-linux-
 gnu/scripts/g.gui.animation", line 141, in <module>
     main()
   File "/home/veroandreo/software/grass-7.3.svn/dist.x86_64-pc-linux-
 gnu/scripts/g.gui.animation", line 112, in main
     layer.cmd = ['d.vect', 'map={name=}'.format(name=vect.split(',')[0])]
 KeyError: 'name='
 }}}

 Listing the maps, however, works as expected, and I get the corresponding
 list of maps. I'm using trunk r69455M under fedora 24.
