[GRASS-user] v.db.connect -p

[Patricio Toledo]

Dear GRASS Developers

This is a petition:

Is it possible to add a option to v.db.connect (like g.region -p) so
the output will be somelike:

    $ v.db.connect -p map=test layer=2
    driver=dbf
    database=/the/database
    table=thetable
    column=thecolumn
    layer=2

i know -p actually does something very similar but this -p output is very useful
in g.region, so one can do inside a shell-script:

    $eval `v.db.connect -p map=test`

to recover database connection parameters.

i have noticed that a couple of vector scripts are very sloppy regarding the
actual connection parameters, and no further checking is done, so the database
connection fails to a default value which is not always triavial. Other scripts
are very careful and use awk/gawk to parse database connection, but i think this
'eval' method is pretty useful and elegant.

Thanks in advance
Best regards
Patricio
