It would be great if the r.mapcalc interface in the Grass toolbox was similar to the r.mapcalc interface in Grass 7.4. Right now, the r.mapcalc interface in the Grass toolbox is a mostly unusable graphical diagram.

Did you see https://grass.osgeo.org/grass78/manuals/r.mapcalc.simple.html ?

@neteler This is not available in the Grass toolbox.

@glaroc it is available in the Processing/GRASS toolbox. The GRASS plugin is also (sadly) unmaintained and partially broken.

@gioman Which parts of it are broken? Should I stop showing this to students in my workshops?

the last time I checked on Windows was not possible to create a mapset/location (crash). I have not tested further. It is a long time now I personally rely only on GRASS within Processing.

Creating a mapset seems to be working now.

@glaroc on what QGIS version and platform? It still crashes here on 3.4/3.10 on Windows.

Seems to work for me on 3.10 on Windows.
