Replace $HOME/.xargo with $XDG_DATA_HOME/xargo

[linkmauve]

In order to respect the XDG Base Directory Specification, like cargo before it, xargo should switch to the standard $XDG_DATA_HOME/xargo directory (by default $HOME/.local/share/xargo when $XDG_DATA_HOME isn’t set).

Cargo uses HOME not XDG_HOME_DIR AFAICT so I'd prefer not to differ from Cargo on this matter.

[linkmauve]

They use $XDG_DATA_HOME/cargo currently, which is already better than yet another dotfile, and are in the process of moving their cache and configuration to the proper $XDG_CACHE_HOME/cargo and $XDG_CONFIG_HOME/cargo directories, respectively.

Huh? Cargo still uses $HOME/.cargo for everything. I know this because I just installed and setup cargo yesterday.

@linkmauve I grepped for xdg in Cargo repository and there's only one match in a test, which actually unsets the env var.

My installation also uses ~/.cargo and there's @SShrike confirmation.

The "in the process" links you mention point to a RFC which hasn't been accepted.

I'd be happy to move Xargo to XDG after Cargo does it but I won't if Cargo doesn't.

I'm going to close this because it's not actionable until Cargo makes the change. Feel free to open a new issue by the time Cargo moves to XDG!

Cargo supports setting the CARGO_HOME environment variable, though, so there should be a XARGO_HOME environment variable.

so there should be a XARGO_HOME environment variable.

@jakbyte is anything wrong with XARGO_HOME? I've been using it for years.

it took me a year to see this, but it does seem to work 🙂
