Hi,
It would be nice if d.legend could look for "map=-" and if so take
legend
cat and color info from stdin. That way vector maps and custom
legends
could be made without resorting to tricks like making a dummy
raster file
to hold
that info. [see v.colors addon script]
If data is fed from stdin (signaled by map=-) create categorical
legend
using that data. Data format: "cat|label|color"
e.g.
{{{
d.legend -m map="-" <<EOF
1|Main Street|255:0:0
2|Elm Street|0:255:0
3|Old Coach Road|0:0:255
EOF
}}}
In this way d.legend could work as a system module by the GUI
instead of
a user module, and be useful for non-raster tasks too.
see expanded thread on the -dev mailing list:

Ironically, I'm stuck in the" North Carolina data set" with a plane
delay after a stint in Washington. But have a chance to catch up on
email.
This is an excellent idea BUT please don't limit it to stdin. Allow
this to be a load from file option so that it can be used from the
GUI too.
Michael
