Install plugins in $__fish_user_data_dir

[Bekaboo]

Hi, first of all thanks for making this plugin!

As said in #568, I think it makes more sense to install fisher and other plugins under $XDG_DATA_DIR/$__fish_user_data_dir instead of $XDG_CONFIG_DIR/$__fish_config_dir.

It seems that fisher implemented this in #571, but after calling fisher install xxx, I find the plugin is installed under my config dir.

How can I install plugins under my data dir? Thanks!

If we modify the directory as you suggested, various elements like functions, completions, conf.d won't automatically load in new shells without an additional startup script (there's nothing fundamentally flawed with that, but I really appreciate how Fisher "just works" now). The PR you're talking about primarily adjusted the location of Fisher's internal data to $__fish_user_data_dir, it didn't change the plugin installation location ($fisher_path).

If you're looking to change where Fisher installs plugins, follow the instructions here.
