Yes I think so too - IIRC in the 1987 GRASS promotional video you see an
example of GRASS being used with a standalone graphics terminal.
How about for GRASS 7 on all platforms, turning d.mon into a script that
runs an image display program that initialises the image it displays
from GRASS_PNGFILE and automatically refreshes the display when the file
is modified? If the display program was simple (I guess a very simple
cross-platform PNG viewer might not be too difficult to implement?) it
could be included in the GRASS source code and would be convenient for
people to use all their favourite non-interactive d.* commands without
having to run the GUI.
Just to add my 2 cents: I've successfully used gqview [1] in that
manner, i.e. leaving it open and displaying map.png. It automatically
updates the images when it changes. I bet there must be several other
programs that do the same, so I don't think we really need to program
anything. Maybe just offer a list of programs that users might consider.
