Accessing configuration across multiple modules

[Loris Bennett]

Hi,

I am using Typer to create a command-line program with multiple levels
of subcommands, so a typical call might look like

  mytool --config-file=~/test/mytool.conf serviceXYZ list people

In the top-level mytool.main, I evaluate the option '--config-file' and
read the config file to initialize the logging.  This works fine.

However, in the module which lists people, namely

  mytool.serviceXYZ.cli_people

I need to set up a connection to an LDAP server in order to actually
read the data.

If the LDAP connection details are also in the config file, what is the
best way of making them accessible at the point where the object
wrapping the LDAP server is initialized?

I found this a suggestion here which involves creating a separate module for
the configuration and then importing it 

  https://codereview.stackexchange.com/questions/269550/python-share-global-variables-across-modules-from-user-defined-config-file

I think I could probably get that to work, but are there any better
alternatives?

Cheers,

Loris
