Thanks to all for your answers, it's great to get good advice quickly. 
It's more clear to me now how to proceed, I'll give it a try !

If you convert your plugin functionality into Processing scripts, then
it's very easy to distribute them, no need create a plugin manually

Just create your scripts and make sure they are available in the
toolbox. Then, in the "Scripts" group of the toolbox, you will find a
tool called "Create script collection plugin". Just select the scripts
that you want to distribute, and it will package them into a plugin
that you can share in the plugins server. Installing the plugin will
add the scripts to the toolbox.

Hope this helps

Have a look at
https://github.com/jdugge/BufferByPercentage/commit/c52d161b40abf6bbd45e7ec421eb311623592e90

That's a similar commit which added a processing module to an existing
plugin.

The hardest(?) part is refactoring your plugin to split all the logic out
from any existing gui. Buts that's a good thing to do in any case.

Sorry if the answers are obvious !

Thanks,

If you convert your plugin functionality into Processing scripts, then

and add them to it.

Just create your scripts and make sure they are available in the
toolbox. Then, in the "Scripts" group of the toolbox, you will find a
tool called "Create script collection plugin". Just select the scripts

Hello,

I think that you can first try to convert your plugin to a Processing 
Python script as stated here:

https://docs.qgis.org/testing/en/docs/user_manual/processing/scripts.html

When you create a Processing Python script from the dedicated dialog, it 
is stored into your ~/.qgis3/processing/script/ directory.
To fill the script code, you will have to extract the "algorithm" part 
of your plugin (the things that do the stats or the dissolve part which 
seems to be stored into 'dissolve_stats_dialog.py') and put it into a 
Python script.


For input/output, just use the dedicated "comments" syntax at the 
beginning of the script:

##myvector=vector
defines an input vector which will be available in myvector Python 
variable.


Once inputs and outputs are defined, there is no need to deal with 
dialogs to open/choose files, just use the "comments" variables and 
Processing will build the dialogs for you.
The script will be processed by Processing as is: the code will be 
interpreted as a Python script. You can add as many classes/functions 
you'd like into the script. Don't use the `if __name__ == '__main__'` 
Python syntax for the main loop. I think it is not interpreted correctly 
by Processing (not 100% sure though).


Once your plugin is converted, you can make a PR to 
https://github.com/qgis/QGIS-Processing which is the repository for 'Get 
models from on-line scripts collection' Processing dialog box and it 
will become available to anybody.



Cheers,

[Qgis-developer] how to turn my plugin into a processing subplugin

[Julie Pierson]

Hi all,

I would like to answer this issue for my plugin : 
https://github.com/UMR-PASSAGES/DissolveWithStats/issues/2, and turn it 
into a processing subplugin. I read this : 
https://docs.qgis.org/testing/en/docs/pyqgis_developer_cookbook/processing.html, 
but I'm still not sure how to go on.


I'm guessing that my script will be accessible from the Scripts/Tools 
part of the processing toolbox. But I don't understand :

- where these scripts are hosted, and how do I submit it
- where do I start ? Should I just make  a new version of my plugin 
without the GUI ?


Sorry if the answers are obvious !

Julie.
