How to setup a new environment variable in a EnvironmentCollector?

[Yves Chevallier]

I would like to write an extension similar to the fig-numbering, but for teaching exercises. I am writing a book and I would like to define an `.. exercise::` and a `.. solution:: ` (nested into it) directives. 

At some point I would like to list all the exercices so I need an EnvironmentCollector that I setup in my application with `app.add_env_collector(ExercisesCollector)`. 

In Sphinx, the fignum environment variable is (and this is very very ugly) defined globally in the BuildEnvironment class which should NOT be aware that a feature fig numbering exists somewhere. 

Anyway. I am surprised that the EnvironmentCollector has no __init__ wheer I can say:

class ExercisesCollector(EnvironmentCollector):

    def __init__(self, app: Sphinx, env: BuildEnvironment):

        env.exercises = {}

What would be the proper way to do this in my extension?

Hi,

The EnvironmentCollector is a collection of event handlers for
environment object. It should not have a status locally. The
environment object is given from outside when event emitted. So you
don't need to give arguments to EnvironmentCollector.

Thanks,
