[Qgis-user] processing script vs. processing plugin

[Ari Jolma]

To me it seems that processing algorithm provider plugins are language 
or tool specific plugins that add a new section to the processing. 
Processing is itself a plugin (although a core one).

I don't think providers should add custom GUIs beyond what is needed to 
manage itself and the algorithms it provides. That is, its GUI is for 
adding, possibly creating, etc. algorithms. It should mostly work 
through the processing plugin.

The "algorithms" are processing tools (scripts, external programs, etc) 
that only have a thin wrapper so that the provider plugin can help the 
processing plugin create a GUI for running it or linking it to other 
tools to create models.

This is my understanding that I've gained by creating a provider plugin 
for Perl programs to be used as processing algorithms.

I'm actually a bit against listing the providers separately since the 
user should not need to care what language or program the processing 
tool is written as long as it does what the user wants.

Best regards,

Ari
