rbenv plugin support for the fish shell.
With fisherman
fisher install rbenv/fish-rbenv
This plugin replaces what status --is-interactive; and . (rbenv init -|psub)
does in a more fishy way. This brings the startup time of your shell down
as we do not generate full completions every time the shell starts but only
when rbenv gets called.
On Fish 2.3.0 and later support was introduced that automatically loads
snippets in conf.d. However, these snippets are evaluated before your
config.fish. If you're setting RBENV_ROOT in your config.fish to
relocate your rbenv installation this will be evaluated after our plugin
gets loaded and hence have no effect. In order to fix this you should drop
a 000-env.fish file in your ~/.config/fish/conf.d folder which sets
up your environment accordingly.
