[GRASS5] making a module that collects pixels values from a displayed map

Hi list,

I would like to make a module that runs some processing, then displays
a map and gives the user the capacity to collect pixel data by
selecting a pixel on-screen for further processing.

Could you direct me towards a good (clear,simple) example module?

thanks,
Yann

Example not, but try something like

for click in $( d.what.rast -t soils 2>&1 |grep "@" |awk '{print $2}' ); do
    echo "your values: $click"
done

for example, how to make a grass script look at help to g.parser module

hope it helps
