[GRASS-user] Add-Ons and batch job with the --exec interface

Vincent_Bain · December 20, 2020, 11:01am

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 :

echo $GRASS_ADDON_PATH
/usr/local/grass-addons/

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.

Sorry for it: I just figured out there was a mess with a wrong symlink
in my addons directory.

Now it's humming!

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

    echo $GRASS_ADDON_PATH

    But :

    fails :

    [Errno 2] No such file or directory: 'r.my.addon': 'r.my.addon'

Thank you Micha for your hint.

Not sure I catch the difference between both directories. Should I
consider GRASS_ADDON_BASE a place I can store my "user" addons, and
GRASS_ADDON_PATH the "system" one?

Yours,
V
