Writing a QGIS Processing Provider

Question

Due to limitations in the processing script framework (for example, inability to specify an optional field) I'm thinking of writing a Provider.

I found the example ExampleAlgorithmProvider but no documentation.

Two questions:

• Are the interfaces used by the example provider considered stable and unlikely to change in any way that breaks compatibility?

• What is the recommended way to distribute/deploy a custom provider?

Answer 1

For the break compatibilty part, I let the dev community answers. For the second part, you can distribute your Qgis Processing Provider like a plugin (it's a plugin).

A good example is the LecoS plugin : https://plugins.qgis.org/plugins/LecoS/
