[GRASS-dev] QGIS-Developer] GRASS and SAGA providers in 3

Yes - it's a work in progress still. SAGA algs are being worked on in
https://github.com/qgis/QGIS/pull/5021, we need someone to step up and
port the GRASS ones. GDAL still has a few left to port (volunteers
welcome), but the QGIS ones are 97% there (I'll do the remainder of
those).

We desperately NEED more people to step up and help here. In the worst
case scenario (no-one ports grass or the remaining GDAL algs) I'll
have to resort to reverting all the c++ processing improvements OR
have duplicate "processingv2" plugin type approach (with only the
ported algs, and a duplicate "processing v1" 2.x style plugin).

Does anyone know the current state of GRASS GIS support in QGIS3?

Thanks,

GRASS support is still completely disabled in processing. Feature freeze for 3
is next friday.

I thought someone was talking care, I read a related email some time ago.

Yes, thanks. I have right now written to Médéric Ribreux to better
understand what the current state of the port is.

tested now in windows.

tested some raster commands (e.g. r.slope.aspect, r.contour, ...); seems to
work so far.

but the vector commands may need some tuning:

it seems that some vector commands (e.g. v.buffer) doesn't work with
v.external'ed vectors.

it seems that some vector commands (e.g. v.buffer) doesn't work with
v.external'ed vectors.

ok, in the settings, following option can be set/unset:

"For vector layers, use v.external (faster) instead of v.in.ogr"

unsetting this option, also vector commands seems to work.

FYI:
For Fedora users, QGIS3 including the GRASS GIS support is now available:

sudo dnf copr enable dani/qgis-testing
sudo dnf update
sudo dnf install qgis qgis-python
