A placeholder for shared read-only data required by a Directive

[BasicWolf]

Hello,

I'm looking for a proper placeholder for the data that is collected during a directive's setup() call, so that the directive can refer to it during run() calls. I.e. something like:

class MyDirective(SphinxDirective):
    def run(self) -> list[nodes.Node]:
        read_my_data()
        ...

def setup(app: Sphinx) -> ExtensionMetadata:
    store_my_data()

    app.add_directive('mydirective', MyDirective)

Is there a place in app to store data for such purpose?

Thank you!

See the tutorials, especially how todo_all_todos is managed.

Thank you, Adam!

Looks like for my case, any event handler which includes BuildEnvironment and happens before source-read should do. But I shall rather read carefully about each event intention.

Thanks again!
