Customizable configuration file location

[nix6839]

Currently, Rio does not support customization of the path to the config file. Ideas for supporting it are collected in this issue.

Current Behavior

On macOS and Linux (current)

$HOME/.config/rio/config.toml

On Windows (current)

%USERPROFILE%\AppData\Local\rio\config.toml

New Behavior (draft)

On macOS and Linux (new)

1. $RIO_CONFIG_HOME/config.toml (if $RIO_CONFIG_HOME is set)
2. $XDG_CONFIG_HOME/rio/config.toml (if $XDG_CONFIG_HOME is set)
3. $HOME/.config/rio/config.toml (otherwise)

On Windows (new)

1. %RIO_CONFIG_HOME%\config.toml (if %RIO_CONFIG_HOME% is set)
2. %XDG_CONFIG_HOME%\rio\config.toml (if %XDG_CONFIG_HOME% is set)
3. %APPDATA%\rio\config.toml (otherwise)

Feel free to share your ideas!

For windows we can use the XDG_CONFIG_HOME as well right?

@raphamorim What do you think about the last fallback path on macOS being $HOME/Library/Application Support/rio/config.toml?

[raphamorim]

I would prefer to keep $HOME/.config/rio/config.toml in macos as the fallback for XDG_CONFIG_HOME and RIO_CONFIG is not set, mostly due to reasons of compatibility to old users
