[RFC] configuration file? about dotslash

[bolinfest]

By CONFIG_DIR I meant the thing that the linked Rust code could would return, which follows the XDG Base directory specification, so I guess I should have said XDG_CONFIG_HOME.

Is there is hierarchical configuration, it would be very useful to be able to ask the tool to display the config values it’s landed on, and ideally to report where each value is set. Can help with debugging when you expect the value to be one thing and it’s something else instead.

Hierarchical configuration like this is great. Usually I'd expect to also see beyond what you already have:

• ~/.dotslash (maybe this is what you meant with <CONFIG_DIR>)
• Overrides with ENV variables

I like https://rust-cli-recommendations.sunshowers.io/hierarchical-config.html for this.
