I've found asdf to be a reasonable choice when needing to manage more than one language - especially where there are good "native" version managers that asdf wrap (eg: python, ruby, node, to a certain extent rust/cargo). Not sure I'd do this, though: mkdir -p ~/.config/fish/completions cp ~/.asdf/completions/asdf.fish ~/.config/fish/completions But more probably add a symlink to the completions managed by git/asdf: ln -s ~/.asdf/completions/asdf.fish ~/.config/fish/completions/
