Custom config path xdg compliant

[adriangalilea]

Duplicate of issue as I just noticed this repo that may be more fitting, keep the one you prefer.

Hello,

I hate macOS paths with caps and spaces,

Is it possible to set my preferred location for config?

I’d like to set: ~/.config/marta reading XDG_CONFIG_HOME following XDG Directory Specification which many programs respect on macOS.

Or simply by using MARTA_CONFIG_PATH env var.
