[GRASS-dev] RE: [bug #4604] (grass) tcl/tk GUI: v.digit can't create new vect or in GUI mode

[Patton, Eric]

Confirmed; some caveats below.

For starters, v.digit from the CLI fails to automatically open an X-monitor;
whether this is intentional or not, it's inconsistent with the v.digit GUI
version, as that one opens x0 automatically.

##################
#  v.digit -n CLI
##################

d.mon x0; v.digit -n map=Bugtest1 
New empty map created.


############################
#  v.digit CLI (no -n flag)
############################

d.mon x0 ; v.digit map=Opilio_ROV_Stations    

using default visual which is TrueColor
ncolors: 16777216
Graphics driver [x0] started
Segmentation fault

This is important - if I try to query the vector Opilio_ROV_Stations from
the gis.m query tool,  topology seems to be destroyed!

$ v.what -a map=Opilio_ROV_Stations east_north=647925.576373,5169619.14795
distance=16.2926107986 (copied from Output screen of gis.m)

(From Output screen): Opilio_ROV_Stations: You must build topology on vector
file

Ok, let's build some topology...

v.build Opilio_ROV_Stations
Building topology ...
18 primitives registered
Building areas:  100%
0 areas built
0 isles built
Attaching islands:
Attaching centroids:  100%
Topology was built.
Number of nodes     :   12
Number of primitives:   18
Number of points    :   12
Number of lines     :   6
Number of boundaries:   0
Number of centroids :   0
Number of areas     :   0
Number of isles     :   0

Now, if I try to edit this vector again with the CLI command 

d.mon x0 ; v.digit map=Opilio_ROV_Stations

using default visual which is TrueColor
ncolors: 16777216
Graphics driver [x0] started
Segmentation fault

Similarly, topology is again destroyed as I can't query this vector until I
rebuild topology.


Moving on to the GUI version of v.digit.....

Running the command

v.digit map=Bugtest2 'bgcmd=d.rast -o
map=CheticampAll_Aug2005_10m.shade.comb' displays my background map in x0,
but no v.digit toolbar opens! The corresponding output from gis.m:

GRASS_INFO_MESSAGE(9662,1): New empty map created.

Application initialization failed: "-n" option requires an additional
argument
Error in startup script: couldn't read file "map=Bugtest2": no such file or
directory

I thought -n was supposed to take care of creating the new vector for me.
What additional argument is it talking about?

Now let's try editing an existing vector through the GUI:

v.digit map=Disposal_Sites 

x0 opens, but that's it.

This bug is still valid in current CVS.
