Hi dear Grass users,
I'm wondering how/if one can run an Add-On command while invoking grass
from the --exec interface.
As an example, if I run :
grass79 /path/to/my/location/mapset --exec g.list rast
I succeed.
As well as checking my GRASS_ADDON_PATH :
Maybe it should be GRASS_ADDON_BASE.
micha@RMS:~$ env | grep ADDON
GRASS_ADDON_BASE=/home/micha/.grass7/addons/
Now before initializing GRASS:
micha@RMS:~$ export GRASS_ADDON_BASE=/home/micha/.grass7/addons/
micha@RMS:~$ grass /home/micha/GIS/grass/ITM/Arava/ --exec r.stream.order
Starting GRASS GIS...
Cleaning up temporary files...
Executing <r.stream.order> ...
Calculates Strahler's and more streams hierarchy.
Usage:
r.stream.order [-zma] stream_rast=name direction=name [elevation=name]
[accumulation=name] [stream_vect=name] [strahler=name] [horton=name]
[shreve=name] [hack=name] [topo=name] [memory=value] [--overwrite]
[--help] [--verbose] [--quiet] [--ui]
Flags:
-z Create zero-valued background instead of NULL
-m Use memory swap (operation is slow)
-a Use flow accumulation to trace horton and hack models
Parameters:
stream_rast Name of input raster map with stream network
direction Name of input flow direction raster map
elevation Name of input elevation raster map
accumulation Name of input accumulation raster map
stream_vect Name for output vector map to write stream attributes
strahler Name for output Strahler's stream order raster map
horton Name for output original Hortons's stream order raster map
shreve Name for output Shereve's stream magnitude raster map
hack Name for output Hack's streams or Gravelius stream
hierarchy raster map
topo Name for output topological dimension of streams
raster map
memory Max memory used in memory swap mode (MB)
default: 300
Execution of <r.stream.order> finished.
Cleaning up default sqlite database ...
Cleaning up temporary files...
echo $GRASS_ADDON_PATH

But :
grass79 /path/to/my/location/mapset --exec r.my.addon
fails :
[Errno 2] No such file or directory: 'r.my.addon': 'r.my.addon'
Exiting...
Would anyone help me solve this issue ?
Have a nice sunday,
Vincent.
