Works like a charm! Anybody minds it applied?
What a nice working Sunday. Thanks Jachym!
I'm wondering if flags should be exclusive or not in Grass modules, in
For example, I asked Jachym to make it possible to his new '-t' flag
not to be excluded if used together with '-g', and it works. No matter
what flag seqeunce, if both are used, first goes the '-g' output, then
'-t'. But maybe I asked him for a wrong thing, maybe flags should be
exclusive? Or if they should be not exclusive, should the order they
are called metter? Eg. should '-tg' and '-gt' output in the same sequence?
Other modules (eg. g.region and r.info) don't allow for using many
flags at the same time, and they have some hierachy in excluding them,
but I can't find a pattern for that (is there one?).
Moreover, I found a strange thing about g.region. Try this:
$ g.region -e
region north-south extent: 270.000000
region east-west extent: 300.000000
$ g.region -g
BUT A COMBINATION OF BOTH GIVES NEITHER OF THE ABOVE:
$ g.region -eg
The region extent is printed, like if -e alone was used, but instead of
"region north-south extent" we get "ns_extent". Same thing, but
