[GRASS-user] How to use g.extension in GRASS7.8

GRASS GRASS user
1

Hi,

I am trying to install the extension r.area using the g.extension tool in GRASS 7.8.
However, I get the error that it was not found in the Github repo (because the repo changed).
Here the error:

g.extension extension=r.area
Fetching <r.area> from GRASS GIS Addons repository (be patient)…
svn: E170000: URL ‘https://github.com/OSGeo/grass-addons/trunk/grass7/raster/r.area’ doesn’t exist
ERROR: GRASS Addons <r.area> not found

I tried adding url=https://github.com/OSGeo/grass-addons/tree/grass8/src/raster/r.area" but it also does not work:

g.extension extension=r.area url=https://github.com/OSGeo/grass-addons/tree/grass8/src/raster/r.area

The command:
g.extension extension=r.area url=https://github.com/OSGeo/grass-addons/tree/grass8/src/raster/r.area operation=add
produced an error (1) during execution:
Fetching <r.area> from
https://github.com/OSGeo/grass-addons/tree/grass8/src/raster/r.area/archive/master.zip
(be patient)…
ERROR: Extension <r.area> not found

How should I proceed to install it in GRASS 7.8?

It should work like this (g.extension will figure out the correct path):

g.extension extension=r.area

HTH,
Markus

PS: Full path is only needed when the addon isn't part of the standard
addon repository but found elsewhere.

Hi Markus,

That was my first try, and then I get the error below:

Which GRASS 7.8 you have and which operating system? Any chances you can update to GRASS 8.2?

Ah right. Then your GRASS GIS 7.8 version may be too old. G 7.8.7
should be ok (G 7.8.8 is on the way these days) but in any case, as
Vero pointed out, we highly recommend to upgrade to GRASS GIS 8.2.x.

Best,
Markus

Hi Markus and Vero,

Thanks. Indeed, my GRASS version is old:
GRASS 7.8.5
Ubuntu 18.04.6 LTS

I unfortunately do not have a way to upgrade it myself since this is a company server shared with other people (and we have been fighting with IT to change to GRASS 8).
But maybe it is easier to at lease update GRASS to version 7.8.7 (or 7.8.8).

I just talked to a colleague (@mauricio.vancince) who mentioned he had the same problem but could overcome it opening the terminal as a superuser and using
g.extension r.area -s
Unfortunately I do not have admin rights, but I will see what is possible to be done.

Thanks!
Best
Bernardo

Hei Bernardo,

The problem is likely that the layout of the addon repo changed after 7.8.5, thus the path is not constructed correctly by g.extension in that version.

A workaround could be to fetch the add on repo with git (git clone https://github.com/osgeo/grass-addons)

And then point g.extension to your local copy:
g.extension extension=r.area url=./grass-addons/src/raster/r.area

You may need a zip file, but you can try the above first...

Good luck..

Cheers,
Stefan

A workaround, without having to upgrade GRASS (which is not a good idea), is to clone the grass-addons repo and supply a local path as extension URL.

 git clone \-b grass7 https://github.com/OSGeo/grass-addons $PWD/grass\-addons
 g\.extension extension=r\.area url=$PWD/grass\-addons/src/raster/r\.area
