This is a specification that allows users to unclutter their home directory by keeping config files in (a customizable) directory and cache files in another one (also customizable). An example implementation for Unix-likes (where it's safe to assume HOME is set) has been attached. Windows has something (almost) comparable in form of the APPDATA (for user-specific configuration) and LOCALAPPDATA (for user-specific non-configuration, exists since Vista) environment variables. In case LOCALAPPDATA isn't defined, APPDATA could be used instead. I'm not 100% sure whether you can just use get-environment-variable on Windows and have it work, someone would need to test this.

With this we could (for both Windows and Unix-likes):

  • Look up a user config/cache directory for the platform
  • Check whether a config/cache file exists
  • If yes, read it from that location, otherwise fall back to a default

The last one is optional and might make this a change request. Falling back to a default would preserve default behavior, ignoring it would introduce a change. Possible candidates include ~/.csirc (config), the egg cache (cache) and setup-defaults (config).

PS: Looking up .csirc on Windows probably never worked as it relies on resolving HOME which isn't set by default. This would make it work again, albeit for a different location than previously documented.
