[GRASS-user] rgrass7 and rmarkdown: how to avoid showing the percentage of processing

Hi,

when using rgrass7 and rmarkdown, is there a way of avoiding showing the percentage of processingo of each command within execGRASS?
It might get really polluted, mainly when I perform a loop or many processings.
See the figure below:
Imagem incorporada

I tried adding “message = FALSE, warning = FALSE” to the chunks, but it does not work.

GRASS GIS itself offers a shell variable to set the message style:

https://grass.osgeo.org/grass78/manuals/variables.html#list-of-selected-(grass-related)-shell-environment-variables

GRASS_MESSAGE_FORMAT
[various modules, wxGUI] it may be set to either - `standard` - sets percentage output and message formatting style to standard formatting, - `gui` - sets percentage output and message formatting style to GUI formatting, - `silent` - disables percentage output and error messages, - `plain` - sets percentage output and message formatting style to ASCII output without rewinding control characters.

In HPC and cloud computing we commonly use “plain”. It prints the percentage like this

0…10…20…

and doesn’t use control characters.

HTH,
