Hi,
Martin:
Markus:
Then rather implement --u as an option for some modules but not all and not
make it global?
Then we end up with the need to update manually every module which can
support update mode. Probably we could build a list of modules where
make sense to have update mode and not (having 'output' parameter).
I think so, too dangerous to make it global. In any case, I don't see a
way around going through each vector module and see if it could support --u.
How about a slight modification of Radim's suggestion:
v.random out=./shapefiles/@OGR,layer=test,format=ESRI_Shapefile
or something similar so that the out option can easily be parsed?
yes, anyway it requires adding 'format' modules to the all vector
modules which have 'output' parameter defined
Hmm, for direct OGR write access, you need to specify the format anyway
somewhere? There is already 'format' added to all vector modules which have
input defined, can't be too difficult. And as I mentioned before, I think a
Probably I don't understand, I can't see 'format' parameter only in
v.out.ogr, v.in.ogr and similar modules. Currently would be possible"
I was referring to grass7 wxGUI e.g. d.vect has a new option element
called Format with the choices Native and OGR and I suggested to (1) do
that with e.g. ./shapefiles/@OGR and make that option element a format
option in the sense of v.[in|out].ogr for output options.
v.out.ogr input=test dsn=`pwd` type=point -n
v.external dsn=. layer=test output=test
v.random out=test n=1000 --u
but probably
v.random map=`p...@ogr n=1000 olayer=test format=ESRI_Shapefile
is better approach.
new output option for output layer could make sense and AFAICT is required
for direct OGR write access.
yes, also olayer would be required. But it would make sense only for
OGR format, not the native format, am I right?
Thinking about it, there may be problems because some modules may
produce several output layers in the same output vector map if feature
cats refer to several layers. No idea how to accommodate that with
direct OGR write access where each OGR layer needs its own name not
number. Fetch layer name from input vector, append layer number to map
name if no layer name available?
v.extract in=imap layer=1 where="..." out="PG:dbname=db" olayer=omap
format=PostgreSQL
v.extract in=imap layer=1 where="..." out=omap format=native
Should work, but preferably use input layer name if available?
