Respect XDG guidelines

[doron-cohen]

Hi,

I saw issue #80 is closed and it seems to be done but the functionality doesn't work. Should it? I would like tfswitch to respect XDG env vars. Alternatively, I wish I could set some env vars to tell it where to store the config and binary.

Thanks

Yes please 👍🏻

For when we get to try and implement this feature request: this seems to be a lib with most active development/support — https://github.com/adrg/xdg

Potential use cases that I can envision:

• .tfswitch.toml
  • User installation
    • XDG_CONFIG_HOME
      • $XDG_CONFIG_HOME/tfswitch/config.toml
      • $XDG_CONFIG_HOME/.tfswitch.toml
      • $HOME/.tfswitch.toml
  • System-wide installation
    • XDG_CONFIG_DIRS
      • $XDG_CONFIG_DIRS/tfswitch/config.toml
      • $XDG_CONFIG_DIRS/.tfswitch.toml
      • ❗ Caveat: since tfswitch defaults to /usr/local/bin it makes sense to search for config file in /usr/local/etc though
• .terraform.versions/ (directory with downloaded Terraform/OpenTofu binaries)
  • User installation: XDG_DATA_HOME
  • System-wide installation: XDG_DATA_DIRS
• ❔ tfswitch binary path (install.sh script)
  • User install: XDG_BIN_HOME
  • System-wide install: /usr/local/bin (current default set in tfswtich)
  • ❓ Do we at all want to mess with this part that is sort of external to tfswitch's functionality?

Alternatively, I wish I could set some env vars to tell it where to store [snip] binary.
