Pretty much the title. I just want to use $XDG_DATA_HOME/tmux/resurrect as my save directory.

Thanks for your hard work.

You can do set -g @resurrect-dir "$XDG_DATA_HOME/tmux/resurrect". Note the double quotes.

The doc is misleading about this. This will work assuming that XDG_DATA_HOME is exported in the environment when your tmux configuration is loaded.

I think this should be re-opened. Being able to set set -g @resurrect-dir "$XDG_DATA_HOME/tmux/resurrect" isn't really supporting the XDG standard.

• Each user must find this themself and configure accordingly.
• As commented by @sgleizes, the doc says one cannot use arbitrary shell variables, so using that configuration is basically "undefined behaviour".
• Implementing the XDG spec means that "if $XDG_DATA_HOME is either not set or empty, a default equal to $HOME/.local/share should be used." (how would users do that without tmux-resurrect support?)

My config is now set-option -g @resurrect-dir "~/.local/share/tmux/resurrect", but I wish I didn't have to do that.

Agreed. This should be the order priority:

• @resurrect-dir tmux var
• TMUX_PLUGIN_MANAGER_PATH (from tpm is present) + /resurrect/
• XDG_DATA_HOME (if present) + ~~/resurrect/~~ /tmux/resurrect/
• $HOME/.tmux/resurrect

XDG_DATA_HOME (if present) + /resurrect/

Nitpick, but perhaps use one of these instead of /resurrect/?

• /tmux/resurrect/
• /tmux-resurrect/

Oh, and more importantly think if XDG_DATA_HOME is unset, the default directory ~/.local/share should be used instead (ref. the spec). That would mean that $HOME/.tmux/resurrect is only used if it already exists, for backwards compatibility.

@bjornfor Exactly! In bash, this would be as simple as using

${XDG_DATA_HOME:-$HOME/.local/share}

to use the default value for the data directory if the envvar is not set.

+1 for being XDG compliant without the need for configuration. Tmux is XDG compliant since v3.1.

Also, why would we default to ~/.tmux/resurrect (or ~/.tmux-resurrect), instead of defaulting to ~/.local/share/...? The latter feels like behavior that is more aligned with the spirit of the XDG specification.
