Hi Germàn,

I successfully used also your code and it really works perfectly.

Thanks for sharing it!

Cheers

I'm developing a Processing provider plugin that needs some external

QGIS and loading the plugin the error message pops up (of course).

Is there a way to have a "more friendly" message without opening the
Stacktrace? For example creating a messagebox/bar with the message
"Install the package.. else you cannot use the plugin"

I've added a simple try/except in the plugin classFactory method but
I'm
still stuck in the loop somewhere.

Thanks for any suggestion

Cheers

Re: [QGIS-Developer] Skip loading plugin if errors

Another solution, not the best one and working just because the plugin 
is a Processing provider would be to put


try:
import external_library
except ImportError:
raise QgsProcessingException(self.tr('This algorithm requires the 
Python .. library. Please install this library and try again.'))


within the processAlgorithm method. I know that if there are many 
algorithms you have to repeat the code for each one, and that if the 
algorithm has many parameters, the user fills all of them and it's not 
nice to inform after, but :)

[QGIS-Developer] Skip loading plugin if errors

2022-12-28 Thread matteo via QGIS-Developer 

Hi devs,

I'm developing a Processing provider plugin that needs some external 
python packages. If these are not installed on the system, when starting 
QGIS and loading the plugin the error message pops up (of course).


Is there a way to have a "more friendly" message without opening the 
Stacktrace? For example creating a messagebox/bar with the message 
"Install the package.. else you cannot use the plugin"


I've added a simple try/except in the plugin classFactory method but I'm 
still stuck in the loop somewhere.


Thanks for any suggestion

Cheers

Matteo
