vifi is a portmandeau of 'Vi' and 'Fish', because it's a prompt for Fish shell,
primarily focused around showing proper indicators when using Vi key bindings.
Requires a NerdFont.
cargo install vifi-prompt
Then add this line to your config.fish:
fish
vifi init | source
This is just something I made for myself. I'm not going to take feature requests, but will accept well-written PRs.
